##VIDEO ID:N60BU4iGEjE## Thank you all for being here tonight. Thanks, Julie. I'm really happy to be here. So as Julie mentioned, I'm Amanda McCarthy. I am a sports dietician, and I'm also the program manager for Sports Nutrition at Children's Hospital Colorado Sports Medicine Center. My role is really taking care of young, young athletes, teaching them how to fuel themselves well for normal growth and development as well as I like to tell my athletes I have some competitive spirit in myself as well, which is why I became a sports dietitian. So not only am I trying to direct them for fueling, for normal growth and development. Health long term. But I also like to throw in some pieces that are going to help them competitively as well. So we're specifically going to talk about sports, nutrition and the teen athlete. Tonight I'm going to cover a lot of ground, but I'm hoping this can be quite informational for you guys. And then as Julie mentioned, we'll have the the Q&A at the end. I'm happy to answer any questions. So where I like to start with my presentations is just my general philosophy on sports nutrition for the young athlete. Often times I see that athletes, families, coaches want to kind of jump to the top of this pyramid and say what's going to make me faster? What supplement can I take that's going to make me a better athlete, make me healthier when in reality what we need to. Be addressing is that bottom part of the pyramid 1st and then building up from there. So we're going to talk a lot about the bottom part of this pyramid tonight and then at the end, I'm going to touch a little bit on that top piece of the pyramid. But basically, to build a solid foundation in nutrition for young athletes, we need to be focused on are they meeting their energy needs. And their macronutrient needs. Macronutrients are protein. Carbs and fat. Are we timing their nutrition appropriately and are we meeting micronutrient needs like their vitamins and minerals, and then at the top of that pyramid I have ergogenic AIDS, which is essentially food based components that have been shown to have a performance benefit. Or supplements that have been shown to have a performance benefit. Now when we look at. The habits of young athletes, it's pretty much in line with other teenagers that we see. They're not drastically different and athletes notes not drastically different than than a non athletic teenager. So when we look at these habits inconsistent, breakfast is very common or missing breakfast completely, poor hydration, poorly time snacking or no snacking, low fruit and vegetable intake, inadequate calcium and vitamin D supplementation, and then just generally like not getting enough food over the course of the day. Is really common. I put little boxes next to these. You can see. Kind of how those relate to the pyramid. But basically if we have. A standard, let's call it a standard tea. An athlete that is missing out on these pieces, we can make up a lot of ground. Not only in their health, but also in their performance just by addressing these pieces of the puzzle. And I'm going to really talk in more depth on each of these tonight. So when we start off looking at an athlete's nutrition needs, energy, total calorie need is always where I start. That is really the foundation of any diet we need to make sure that we're getting enough calories plus protein, carbs and fat to be meeting the needs of the athlete. If we're not doing that, then we are interrupting normal growth and development and we're absorbing. Going to be performing our best. So the chart that I've put up here today is the recommended dietary allowance for athletes. This is very general, so it's only an estimate and the what the numbers that you're seeing in the chart is for just low activity levels. So like. Going to school, hanging out with friends like no organized sports. So if you can see for our males between the ages of 15 and 24, I know it's a little bit beyond our age range. But basically our older teenag. About 3000 calories per day is normal. Low activity energy needs, and if you have a boy in that age range, I'm hoping you are seeing that amount of energy go into their body and are like holy cow, this this human can eat a lot. Females a little bit lower, but still pretty high energy needs around 2200 calories. Again is a low active energy level and if you look to the right of that where I've put my estimates I'm seeing with activity depending on the amount, the duration. The intensity of the activity they're doing, I can see male athletes anywhere from 3000 level all the way up to 6000 calories a day, and female athletes anywhere from 2200 up to about 4000 is pretty common. I've seen female athletes even be a little higher than that. So basically, teen athletes have really high energy needs. Now the breakdown of that energy needs. I like to think of it in three buckets. So we have our resting metabolic rate, which is in green. Resting metabolic rate is essentially the amount of energy we need for normal organ function. So this includes things like just normal brain function, breathing, heart rate, blood pressure management, muscle tone, body temperature, which takes an exorbitant amount of energy. All of that adds up to be about 60 to 70% of our total energy expenditure for the day. As an athlete. Now on top of that, in that dark Gray box, you see just kind of like normal daily activities that someone might be doing walking to the. Bathroom getting out of bed, going and sitting on the couch, walking to school, all of those things. And then our sport category is that light Gray. So that's gonna vary just depending on the type of sport that someone's doing. And again the amount, but generally around 25% of total energy expenditure is coming from sport and sometimes people are surprised to see that. Most of that energy expenditure is still coming from rusting metabolic rate, but maybe not now that you've seen the numbers ahead of time. So going into individual macro nutrients or macro nutrients are the ones that provide us with energy. We're gonna touch on these briefly, and I'm just gonna expand into more of the athletes base on these. Probably all of you are aware of protein. You're probably aware that it's a building block for muscle tissue. It also helps with building basically any component of our body. So soft tissues bone is going to be included in that and enzymes are all built by protein high protein foods. I have a list of those here. The ones on that first column, the fish, meat, poultry, tofu, those are your more protein dense items. So they just have more protein per volume, whereas things like whole grains, fortified cereals, nuts, and seeds. Those absolutely have protein in them, and they're great foods to add in. They're just a little less dense. So if I have an athlete that does need more protein, potentially we might be looking at more of those denser options to increase their protein intake. When we look at total protein needs, you can see that I've broken down the size of different athletes and approximately how much. Protein they're needing on on. Daily basis and so that is a total for a day not per meal. And then those portion sites that they gave you like the palm of the hand, the fist for vegetarian protein options, those add up to about 20 grams of protein. So if you think about what size your athlete is, I'm going to use 140 LB athlete in in future examples. But we'll take that 120 LB. Athlete on the low end. That is still enough protein for normal muscle development, strength development, bone growth like that is. Of protein. For them, the reason I have a higher range is that they're eating so much energy. They need so much energy, it can almost be hard to keep protein that low. So having 100 ish grams of protein a day for an athlete, that side is is really normal. And if they're eating a very diet and meeting their energy needs, that's generally pretty easy for them to meet. Protein choices per meal. I'm not going to go in depth here, but these are just some suggestions on where we could get protein at each meal and I think this is one of the areas. Do see athletes struggling is if we're skipping breakfast, if lunch is ramen and that's it, right? Or Mac and cheese. Although Mac and cheese could have some some good protein in it. If we're not getting a dense protein choice. Or we're skipping meals. That's where we can see that protein is not going to be spread throughout the day, which is going to be more ideal for recovery, muscle building, bone building. Now, in childhood and adolescent, these are what we call positive nitrogen states for for us as humans, pregnancy is another. Positive nitrogen. State it's basically an anabolic state of our lifespan where we're building tissues, right? That makes sense. They're growing. They're gaining muscle mass. We're building things so in you can see in peak growth that males are putting down a lot. A lot higher lean mass accuril than females, but females are still accruing quite a bit of lean mass, and that's why we're targeting that slightly higher protein amount. So you've probably heard the recommended dietary allowance for protein for the average adult is .8g per kilogram. In young athletes, it's 1.5g per kilo, so it's significantly higher. But again, their energy needs are also significantly higher. So it's relatively easy to eat or to meet and eat the athletes that I will often see again that are missing mills I'll see are a. Little bit lower on protein needs sometimes. My vegan athletes that don't have a very varied diet or vegetarian athletes with low variability. Their protein intake might be low, but generally my athletes are doing a pretty good job on protein overall. In the same vein as protein, I like to focus on a amino acid called leucine. Amino acids are building blocks to protein. You may have heard of them before. Leucine is just one in particular that turns on enabilism in the body. So from a recovery athlete standpoint, this is a really important one to be incorporating. So foods you can see on this table you can see kind of total protein content. You can see portion size and you can see Lucene content in that third category there. So our target per meal is really that 2G of leucine at each meal and then post workout is another important time to have that leucine content. This is only a a small snippet of this whole table, but foods that are going to be highest in leucine are going to include meats, fish, dairy products and then soy products. Those are really your most bang for your buck. While a vegetarian or vegan athlete could eat. Nuts after a workout and get enough leucine. It's gonna be something like 2 cups of nuts if I'm remembering correctly, which that's a lot of nuts, and that's a lot of energy. And they're probably not gonna be hungry for a meal after that, right? So if we think more in what makes sense for the meal, what makes sense to make sure we're meeting our nutrition needs totally those four foods I mentioned are going to be a little bit easier to hit that leucine target, especially if you've got like a snack after. A workout. OK, moving on to carbohydrate next, I would argue that carbohydrates is one of the most important nutrients for young athletes. This is the brain's favorite nutrition source. So the brain prefers to run on carbs. You're going to have better focus, better attention if you're if you're eating adequate carbohydrate. Same thing the body's preferred fuel source for high intensity activity and endurance activity is carbohydrate. It's a clean burning nutrients. So the byproduct of carbohydrate metabolism is water. Whereas other nutrients have other byproducts that are secreted after they've been metabolized. So we want to make sure athletes are getting plenty of carbs. These also provide lots of vitamins and minerals for them to meet their very high nutrition needs and high carbs foods are all over the place and they're relatively varied. So it's going to include a wide vari. Of fruits that's going to include all of your grains all the way down to things like desserts, sweet foods, sports drinks, all of those are going to contain carbohydrate. So we'll see a variety of those foods incorporated. To the diet to meet the athlete's carb needs. So when we're thinking practically about carbohydrates being added onto an athlete's plate, it should generally be somewhere between 30 and 50% of the plate for total energy needs. We're trying to get about 50% of our total calories from carbs. Specifically, that's what's been shown to have best performance and best meat. The nutrition needs of the young athlete carbohydrate before. A workout is ideal. We can top off energy stores. We typically see perceived exertion being lower during exercise. There's also some research that's pointing to that's helpful for bone health as well. Having some carbs pre workout and then post workout we're going to work on that combination of both carbohydrate and protein after the exercise. So that protein that we just talked about is going to help with muscle recovery, bone recovery, more that tissue building, whereas carbohydrates are going to help with. Restoring glycogen stores, which is the storage form of carbohydrate in the body. It's also going to help with anaerobic. Glucose storage. So restoring that glucose that's available for a two second all out effort. So if someone's doing like a hard weight lifting effort or sprinting 100 meters, building those stores is important so that we can see that performance improvement over time. One note that I like to put on all my presentations is that things like cauliflower, rice, and zucchini noodles are really not good substitutes for athletes. These are great vegetable sources. I love when my athletes want to eat zucchini and cauliflower, but if they're using that in replacement of regular rice. Or regular pasta noodles rice noodles. Chickpea noodles. They're just significantly lowering their carbohydrate intake and the amount of volume they would need to eat to meet their carbohydrate needs would be really, really high and probably beyond what their appetite would allow them to eat. Not to mention if they ate that volume of ca. Rice. It's probably going to be a whole head of cauliflower. And so there's going to be some digestive distress that's going to come up with that as well. From a carbohydrate standpoint, we see in teens that their anaerobic carbohydrate utilization is less efficient than in adults, and so we'll continue to see their power and top and speed improving as they're getting older. Endurance utilization of carbohydrate is pretty similar to that as an adult and in. Obese versus non obese youth. It's pretty similar again to adults as well. When we're exercising less than an hour, carbohydrates not really necessary unless we're going out for a really early morning workout. And we haven't eaten anything pre workout. So having something to eat before that workout is ideal. I do have some swimmers and some runners who are getting up and going at 5:00 or 6:00 AM, and so they're not always that interested in getting up early enough to eat something which totally makes sense to me. But in that case, having some fuel on their on. Their actual workout is going to be helpful. Number one, to reduce perceived exertion. #2 to again make sure we're meeting that energy need during that workout somewhat and then we can refuel after that workout. And then this just that last point, just talked about kind of carbohydrate metabolism and young boys. It's pretty similar to what we're seeing in, in adults. We don't have the data on young girls, unfortunately. So total amount of carbohydrates that are needed. I just like to emphasize this point because I feel like it's a lot more than what people expect. So before an event, typically we're targeting about 1 to 4G of kilo or crumbs per kilo, about one to four hours prior to that exercise. So. For a 140 LB individual who's getting ready to compete, that's gonna be somewhere on the minimum side of 60 grams of carbohydrate and on the high side, 120 grams of carbohydrate. I know I'm using a lot of Graham numbers, so to put that in like practical standpoint, a slice of bread, regular bread, not altered in any way is about 20 grams of carbohydrate. So that individual that I just mentioned is gonna need anywhere from three slices of bread to six slices of bread. If we're just putting in. ICal terms. Now I don't necessarily expect an athlete to eat half a loaf of bread in one sitting before their event, so we would be mixing it up with maybe oatmeal or granola or cereal or fruit, right? So there would be a a combination of different foods that are contributing to that carbohydrate for daily recovery. And just again meeting energy needs. Overall carbohydrate needs are high. So for that same sized athlete, 140 ish pounds. If they're doing around one hour of exercise most days of the week. Four to five days a week. Their carbohydrate needs are around 300 grams for the day and that is normal and appropriate for for a teen athlete. If they're doing higher levels of training and extending more energy. So let's say closer to two hours of exercise. Most days we're talking probably closer to the 500 gram carbohydrate mark at that point. And then during sport, again when we are getting beyond that one hour mark, we would want to make sure that we're adding in sport strength that has carbohydrate and also salt. And then when we have more extended periods of exercise, we're generally targeting about 30 to 60 grams of carbohydrate per hour. OK, for fat, fat is our last macro nutrient. Fat aids in a lot of different metabolic processes, including regulating body temperature, hormone production, vitamin absorption, and can help with reducing inflammation. Foods with fat are listed there on the side with the oils and avocado. Those are foods that are mono and polyunsaturated fat, so they're typically liquid at room temperature. Aside from the nuts and avocado. And the ones that are more solid at room temperature are considered saturated fats. And that's the other column that you're seeing. Athletes need a mixture of all of these, and so there's none of these that we should be completely avoiding. But there is research that shows getting more of the ones from the oil seeds avocado side that can help with lowering inflammation a little bit more. That can also help with heart disease risk factors. That helps with joint health. So overall, we try to focus a little bit more heavily on that side and then sprinkle in the the favorite ones from the other side. Fat prescription needs are a little bit different than carbohydrates and protein. There's not necessarily a specific amount of fat that we're looking for on a daily basis. So generally we look at like 20 to 30 fiveish percent of total energy needs for fat. I like to think of it as adding it as a compliment to the meal. So if you're having a potato, you're putting butter or sour cream or cheese on it. If you're having a salad, you're putting dressing or cheese or nuts, or a combination of all of those things on it, right? I would say generally, teens are poor at getting an omega-3 fat, which is coming either from fish. Sources like mackerel, herring, tuna and salmon, if you can eat those two times a week, that gives you your Omega threes for the week. I find most of my athletes don't meet that target. You can also get it from plant based sausage which includes walnuts, chia seeds and ground flaxseed. You do need to eat at least 2 tablespoons of those every single day in order to meet those omega-3 needs. But that's a really good fat for athletes to be incorporating for all of those reasons. But then it's also been. Shown to be protective with the brain. And so if your child is in a sport that is high risk for concussion, incorporating more of these foods and getting more Omega threes is really important for just brain health in general. So how do we structure this logically when we're actually looking at a play and building a play? How do we put all of this into practice? Yes. And so I think these are the best tools that can help both athletes and parents long term when we have more of that moderate training and take this with a little grain of salt because if I have a smaller athlete versus a larger athlete, I may start. With a different plate, just depending on their nutrition needs. But say we're exercising about one hour a day. This would be the plate. I would generally choose for an athlete with a third of their plate grains, a third of their plate from a colorful food, 1/4 from. Protein and then some fat added in on the side and then as exercise goes up, as I mentioned, carbohydrate needs will go up. So now we have half of that plate from our grain portion, 1/4 from protein, 1/4 from our colourful foods, and you'll notice that fat portions also. Increase to help meet our increased energy demands. This is still assuming that the athlete is eating the same amount of snacks because our goal is really to increase total energy intake. Now I threw some sample size in here and my understanding is you guys are going to get the slides as well so that you have some resources on what are good choices. Pre workout post workout and such. So pre workout snacks again we want to focus on more easy to digest carbohydrates, granola, granola crackers. Fruit cereal. Those are all really good options pre workout. They're mostly carb. They're going to digest really fast things like crackers with cheese, yogurt, PB and J sandwiches. Trail mix. Those can also be really great choices, but I would say if you have a kiddo who their stomach just doesn't feel super great when they exercise or there's more prone to that GI distress, I would I would probably avoid those. Those food items that just have a little. Bit higher protein and fat content. They just take a little bit longer to digest. On the post work outside again, we want that combination of protein and carbohydrates after the workout. This could be a snack post workout or it could be a meal. If they're coming home from practice. One thing I would say is that there's going to be a delay from. The end of practice until a meal that's like 2 hours or three hours long. Then I would still try to get that snack item in immediately after an exercise. Within an hour, ideally so that could be chocolate milk, a Turkey sandwich. Salmon with rice and veggies. Some string cheese. Fruit or crackers? Any of these options could be great options to meet both of those needs. And then if we look at the sample menu here, you can see that I tried to keep it really simple from a food choice. So that hopefully it's mostly teenager accepted here and this is just one sample plan and to be perfectly honest, the portions are a little trivial because it's gonna it's gonna change based on the athlete, their sport and how much energy they need. But generally toast with peanut but. Greek yogurt and granola in the morning. Maybe a deli meat wrap with apples and chips on the side for lunch. A banana and granola bar. Pre practice chicken Alfredo with Sal with salad and garlic bread for dinner and then some nuts and berries. Before bed snack. So hopefully this seems like something that's relatively doable. It doesn't have to be. A crazy meal plan to be able to meet the nutrition needs of our teen athlete. So what does poor fueling look like? I get asked this question quite a bit and one of the things I'm really looking for is is the athlete needing their daily nutrition needs and if they're not then I have lots of questions and probably some adjustments. I'd like to make. So the the categories that I typically see athletes fitting into. They are back loading their nutrition intake. They're under fueling. They're restricting their food intake or they tons of fast food for all their meals, right? So with a back loading type of fueling pattern, I see kind of a standard practice where athletes aren't eating breakfast 'cause they're in a hurry to get out the door they're having a. Pretty small lunch. They're not having a snack before practice, and then they're starving, right? And that makes total sense. And they eat a boatload of food at dinner, and they eat a boatload of food after dinner because they are starving. And it's good that they're eating that amount of food because they are hungry and they need to be eating their energy needs. But we can make a lot of adjustments to this. Which is going to help them have more energy during the day. It's going to help them recover from exercise better. It'll help them play better during their sport or run better, whatever their sport is. And they should feel a lot more comfortable by the time they're actually going to bed at night. For my under fuelling athlete, it's kind of similar to backloading, except they don't backload, they just eat small portions all day long. There can be a variety of reasons why this is happening. Sometimes athletes hunger cues are poor and so we need to work on just getting them to consistently fuel more adequately. Sometimes there's intentional restriction going on where an athlete doesn't want to eat too much for fear of what might happen with their weight. But this is putting an athlete at pretty high risk of injury long term and we're going to talk about that in a minute. But we would. We would correct this by adding more fuel across the day. A restrictive eating pattern is when an athlete is cutting out one nutrient group or one whole food group. So hopefully you can see from that pattern there that the athlete is lowered their carbohydrate intake pretty significantly. Replacing regular pasta noodles with Zoodles doing mostly protein foods and in fats throughout the rest of the day. They may be meeting their energy needs, but without that carbohydrate again the brain is having to change the way that it processes fuel, which can be really hard for con. And focus. And there has been a correlation with low carbohydrate diets on increased bone risk factors, so increased risk of stress fractures. And there's been correlations with that in. Irregular menstrual cycles in female athletes, too. So low carbohydrate diets leading to. Periods of amenorrhea, or lack of a menstrual menstrual cycle. So hormone adjustments finally for fast food. Pretty straightforward. They're seeing fast food at each meal, and so we get worried that they're just not getting enough variety of nutrients, specifically colorful foods, specifically, fiber from whole grains. And so I don't. I absolutely don't mind if my athlete is eating out. I think that's pretty expected with the type of schedules that they have. But we need to be bringing some foods from home or we need to be intentional about the restaurants that we're choosing so that we can get a wide variety of foods incorporated. OK, moving on to hydration, hydration water is another essential nutrient and our bodies are anywhere from 60 to 70% water, which is pretty incredible when you actually think about it. We're mostly liquid. Fluid sources that I like athletes to be choosing are things like water, sparkling water, unsweet black and green tea or milk. Things like black coffee sports, drink, sweetened beverages, diet drinks, juices, all of those can be incorporated in. I just ask that my athletes don't drink those. The majority of the time. That's something like fun and delicious that they want to add in. The only drinks I drinks, I ask my athletes to avoid our energy drinks and alcohol. Alcohol hopefully is pretty straightforward, has no benefits from it for performance or for health, whereas energy drinks. They the labeling on energy drinks used to be that they were all labeled as supplements. We'll talk about that in a little bit, but that was that's not ideal. Now they've moved to more food based labeling. Caffeine is disclosed on the label, but a lot of them still have pretty high caffeine levels. The American Academy of Pediatrics recommends that all teen athletes have 100 milligrams or less of caffeine a day. Most of them have about two. Oh, oh, milligrams of caffeine. Often they will contain banned sources of stimulants. There's a popular one in particular that contains guarana and that one is banned at the collegiate level for high level athletes. And then they often will contain really big doses of vitamins in them as well, which which athletes don't need. And so the risk of an athlete taking this and then going into a high stress situation on their body when they're playing sports. Is not worth it. And so my question is always to ask the athlete why they're drinking those and if they feel like they need a pick up from the stimulant, we really need to investigate what's going on with their nutrition, what's going on with their sleep and their recovery. And if if all of that is looking pretty good, which usually there's some adjustments we can make, then we can go towards more natural sources like tea or coffee or some dark chocolate to get some caffeine in. So how much water do athletes need? You've probably heard the general like half your body weight in ounces. That's a good rule of thumb for an inactive person. Inactive person and when we start to add exercise on adding somewhere between 10 and 30 oz per hour of exercise is appropriate. If an athlete is really working on that 30 oz per hour, they don't need to drink all of that during practice, but it should be generally. If they drink 16 ounces during practice, they should be replacing with an additional 16 ounces. After practice. A really simple tool is just have them look at their pee when they're going to the bathroom throughout the day. Ideally, their pee would be out of Level 3 on this chart or or higher, so 1-2 or three is considered hydrated when we start to get lower than that, that darker urine is indicating that we're less hydrated, which is normal for our first morning urine or right. After a multivitamin. But if it's happening all day long, they're probably just not very well hydrated. Sweat rates can be super high in athletes. Especially larger athletes. So really tall guys, especially if they're wearing pads for football and they don't get normal evaporation, they can lose a whole lot of sweat up to somewhere around 2 liters in an hour. So if you think about a two liter bottle, that's how much some athletes will lose in an hour sweating. That's a lot of fluid to replace. If someone is not taking drink breaks and hydrating throughout practice, that will significantly impair their performance and then also can become dangerous if practice is long enough. So general hydration guidelines for our younger athletes 9:00 to 12:00, about four to 8 oz every 20 minutes. Our older athletes, again around a leader, maybe a leader and 1/2 for that hour of exercise. I don't expect that athletes are going to start drinking that during their exercise immediately, but working to replace that after exercise and working on sips of fluid during exercise is import. And then on the bottom, those guidelines for. For during exercise hydration, type again water under an hour. Is great, unless it's maybe competition or an all out effort. And then sports drink is appropriate. If we're over that hour Mark, then we're going to switch to sports drink. If we're over the hour and a half mark, then we're going to be really intentional about making sure we're getting a specific amount of carbohydrate and to sustain activ. OK. So we're gonna switch gears and go into weight control in, in adolescent athletes and adequate fuelling. So I'm first going to talk about weight control and this comes up a lot in my office where athletes are worried that their weight is too high or that they need to bring weight down to help with performance or to help with a certain aesthetic if their SP. Is aesthetically based and really in developing athletes, weight loss is not recommended. And so I'm not manipulating a diet to help an athlete lose weight. I will look at their overall nutrition and see where it is in terms of adequacy for all of those nutrients we just talked about and if it appears that we're having larger portions at some time and lower portions at another time, we might make some changes to that. Which is going to help them better produce muscle mass. Better utilize their metabolism. It may not help them lose weight, but it will help with their performance. So I really try to talk about let's change your nutrition to manipulate performance. Health as opposed to manipulating your weight, which is typically not very helpful for most people. We have a pretty high risk of low energy availability or not meeting calorie needs in very active populations, and hopefully that makes a lot of sense based on one of those first SL. That I showed you. Beaumont's risk is high if we restrict in calories and disordered eating and eating disorder. Behavior goes up if we're restricting energy as well, and just on in that same line there's data that shows up to 81% of 1010 year olds are afraid of being fat. And those thoughts and beliefs about body image can start as young as six. And so we want to make sure that we're really raising these determined, smart, strong individuals to feel comfortable and confident in their body image and comfortable and confident in their food choices so that they. Can maximize their performance and not worry about weight or anesthetic. And that can be really hard in those aesthetically based sports, I understand as well. On the opposite end, I will also see athletes who desire to gain more weight so they may be on the high end of the typical like weight, BMI skills that we look at. They may want to gain more weight, thus not uncommon. One of the things that I will also educate families on is that we need adequate androgens available. So adequate testosterone available if we're wanting to gain size, however, we can manipulate getting stronger by changing nutrition training patterns and sleep patterns. And so again, we want the athlete to stay within a healthy range for themselves. We want to help support their goals as much as possible, but we also need to let their body progress through puberty. Normally in order for them to be able to achieve those things. Any weight changes again ideally would take place in the offseason and only when age appropriate, and having a discussion with your medical provider, a sports MDI think would be a really great choice. And then if you have a dietitian, they they can also contribute to that conversation. So what we get worried about with weight manipulation is a condition called relative energy deficiency in sport. It's shortened to Reds and basically when an athlete is taking in too little calories, we start to see adjustments in the Physiology of the body to accommodate the lower energy intake. And so how I describe it to my athletes is that we continue to exercise. So we're ex. Energy there, we continue to wake up and move about through our day. So we continue to expend energy there. So where the energy gets taken away from is the RMR, the resting metabolic metabolic rate. Normal organ function, so we can often see adaptations like lowering hormone levels where some female athletes may lose or have inconsistent periods. We see bone metabolism declining and in teen athletes, bone metabolism is the highest rate it's going to be in their entire lives. So we don't want to see that. Slow down. We want to keep that going very quickly. We can see thyroid hormone declining and just overall metabolism decreasing. We can see red blood cell production decre. And so it can have some really, really big effects on the Physiology of the body. If we're not getting enough calories. The sport prevalence of Reds as, as you might imagine, sports that are focused on aesthetics, sports that are focused on a power to weight ratio. So more of your endurance based sports and sports that are anti gravitational. So think of climbing and gymnastics. Those tend to be the highest risk sports, but I have worked with athletes at. Again, all levels in a wide variety of sports, and I've seen under fueling in every single sport, even things like football, where I think a lot of people don't necessarily suspect that an athlete would be under fueling. So the overall prevalence of low energy availability is 22 to 58% in all sports. Four year athletes. These are the performance changes that they're going to experience. They're going to see a decrease in endurance. They're going to see a decrease in concentration. They're gonna see a decrease in power, a decrease in speed. All of those things are declined and for any athlete, they're generally not very excited to see a decrease in anything performance related. Often these athletes will present as they've increased their training and they haven't increased their fueling and so paying attention if your athlete is going from not doing anything to doing a lot, their food intake should also be increasing. So that can be a red flag if it's not continued exercise through injury or overtraining with an injury. Loss of menstruation is a big red flag, a preoccupation with food or highly restrictive diets. Continued training with decreasing performance, so maybe you don't necessarily notice anything, but they're still working really hard and. They're just getting slower and slower, or they're having a hard time keeping up in practices and an emphasis on a certain aesthetic or look, not one must have with their sport. Functional hypothalamic aminoria is the technical term for a loss of of menstruation related to not getting enough calories. We have a good amount of data on this. This is called the athlete triad. This is clearly since it's related to periods related to female athletes. Male athletes also experience it. We just have lower data on them since we we don't see the the menstrual cycle happening like we do in women. But when we have normal energy intake we can we see normal estrogen levels and we see normal bone health. All three of those things are related, so. If calorie intake goes down, we see a slowing of the bone growth factors. If estrogen is is too low and we're not able to build the lining of the uterus. We see that directly correlated in in women who have gone through menopause when estrogen drops. Bone health starts to drop pretty rapidly. We see the same thing in teen athletes. If they stop having periods at a time in their life where they're supposed to be having very rapid bone growth. And again in boys, what we're seeing is more related to testosterone. So we'll see that testosterone level dropping. We still see that impact on bone health from the lack of energy intake as well. Relative energy deficiency does not just happen in teen athletes. It happens at all level of athletes. So Sean Johnson, she went to the Olympics in 2008, won a gold medal. She was 12 at the time. She was taking in a 700 calorie diet reports not having grains at that time, and she performed so at a very high level, but also reports the amount of dizziness that she had in a very scary sport where she's going upside down. On a very small apparatus. And how long it took her to regain her healthy relationship with her body and her food? Missy Copeland is a dancer. She's a ballerina. She didn't even start her period until she was 19. What's considered normal is under the age of 15. She was reportedly asked to lose weight a lot and admittedly was binging after performances. And then Mary Kaye is a distance runner. Most people heard about her. This was a while ago. Now it was 2018. That her story came out. She was a high level high school runner, went professional right after high school, encouraged to lose weight. How to negative relationship with the coach lost her period and ended up with five fractures. Fractures. So all of these ladies have struggled with energy deficiency in sport. The stories about males are fewer and further between, but they're starting to come out a little bit more. But I think it's helpful for athletes to hear teen athletes, especially to see these stories that have happened and know that people at the highest levels are also. Was struggling so low energy availability exists on a spectrum from just under fueling. So like the athlete, I said that just doesn't get normal hunger cues. They're not taking in enough, but they don't mean to not take in enough. That's a pretty for the most part, easy case to fix to disordered eating, where an athlete is maybe experimenting with some fad diets. They're intentionally restricting their food or changing their food for whatever reason, at two of full blown eating disorder where we would include diagnostic criteria for anorexia or bulimia. All of these are treated similarly and that we need to probably increase and regulate their food intake so that they. Meeting. They need for their normal exercise output, but the amount of people involved in the team and the approach are all going to vary slightly. Development. I like to talk about disordered eating and eating disorders in sports because athletes just have a higher risk than the normal population. As I mentioned earlier, athletes, especially high level athletes, tend to have some of the personality traits that do put them at higher risk for eating. Disorders. So they tend to be very determined. They tend to be able to. Move through pain at a higher rate than most individuals. They tend to be very independent and strong willed, all of which are great traits to be a high performing athlete and also they can be great traits to restrict food and maintain discipline with food and potentially get a. Little too niched in with food, right? So it's important just to pay attention and again make sure that we are supporting our athlete to include all foods in their diet and have that healthy relationship with. Their body, as they're continuing to move forward with their performance. OK. Last slide that I have on wait, I love this graph. This study was done a few years ago at this point, but this study was done on the top 100 runners in each event across the world, and they looked at what are the size of these athletes. Who are the fastest 100 people in the entire world? And I think it's really cool to see we have the distance all the way up to the marathon, which is 26.2 miles. Down to the 100m, so if you can see something like the marathon with the gold line, you can see maybe the mid range there is around abmi of 20 but the range is anywhere from like a 15 to. I don't know 2627 total. So there's a huge range and these people are all very, very fast, right? And if we go down to the 100 meter, the range grows a little bit more and you can see the shift up in BMI, which makes sense to me because they need more. Powerful units on their body, right? So we have more muscle mass, we have more mitochondria available to ramp up the speed for a shorter period of time. That makes a lot of sense. But again, the range is huge. So. Maybe a 1718 on the low end up to a 3132 on the high end. So I like to show my athletes this to say like, look, these people are all incredibly fast and they're all different in size. We're not seeing everyone just kind of narrow into one specific area. Obviously there's peaks, but there is a big range there too, and we're talking the highest level performers in the world, which is pretty incredible too. OK. We're gonna switch gears and go to micronutrients next for the teen athlete from a bone health perspective, we talked a lot about this. I feel like already, but calcium invited. We are going to be incredibly important. Calcium needs for teenagers are the highest that they'll ever be in their life. They need 1300 milligrams of calcium per day, which is the equivalent of about four high calcium foods per day. Often in my teen athletes that they're moving a little bit away from dairy milks and going more towards non dairy alternatives, which can be fine, but they're not all equal. Dairy Milk is naturally high in calcium. Plant based milks are not and so we need them to be fortified if they're using them that as their calcium source. So making sure you're looking at the label on your milk, make sure it has 30% or 300 milligrams minimum of calcium in it. If your kiddo is going to be using that as their calcium source. Vitamin D. Lots of athletes are not adequate in vitamin D. We can see this being linked to muscle pain, bone pain, muscle weakness, a slower rehab rate. We consider lots of things when we're looking at vitamin D and it can be helpful to get blood work done and we make adjustments on supplementation if needed at that point. But generally, just adding in those beverages that are high in calcium often they're also fortified with vitamin D so you can look for that as well. Vitamin D foods include things like egg yolks, which have a little bit of vitamin D in them. The best vitamin D source is salmon. And so if you're a kiddo, if your kids like salmon, like you're in a good spot, just serve it to them more often for sure. Food sources we just talked through this. The other ones I didn't mention are tofu and edamame are great sources of calcium for our vegetarian vegan athletes, and then green leafy vegetables. I'm seeing those comment pop up more sushi. Absolutely. Green leafy veggies are also another good source. It is 2 cups for one high calcium food, so a lot of my athletes are like oh, I eat green. So that's my. That's good for calcium. We're talking like half a tub of one of those big things of spinach a day to meet. Calcium needs, so don't think that's the most effective way to get all of your calcium in. Iron is another super important nutrient for growth, development and athletic performance. Post puberty females. So those who are menstruating have high needs at around 18 milligrams per day. Vegetarian vegan athletes also have higher needs. They need about 1.8 times what an omnivore athlete needs just because of the amount of fibre and phytate and other. Food substances. From a vegan and vegetarian diet, they just don't absorb the iron as well as athletes who are getting more of an omnivore diet, so their needs are very high. Things like meat, fish, those type of proteins are very high in iron and it's the most absorbable form of. Iron in the body for our bodies, but things like whole grains, fortified cereals, beans, legumes, nuts, green leafy vegetables, seeds. Those are all really good sources as well. I would say generally the kids that I see that have the best iron profile. Are getting adequate energy intake, and they also often eat fortified cereal on a pretty regular basis. I feel like that's one of your best bangs for your book from an iron standpoint, adding things that are high in vitamin C has been directly correlated with higher iron absorption and. Higher iron stores, so adding oranges to breakfast or lemon on your chicken at dinner. Strawberries with lunch. All of those are really. Efficient ways of adding a little bit more iron. Absorption, at least to your day. And finally, from a micronutrient standpoint, potassium and folate tend to be lower in our teens, especially teen athletes as well. And just getting a higher dose of antioxidants can be helpful for them because of the the higher amounts of damage they're putting their body through. Exercise is damaged. That's how we build it and get it stronger. That's how we get better at our sport, but we also want to make sure we're addressing that through our diet. Most of my athletes are not getting enough. Fruits and vegetables targeting 3 pieces of fruit per day and two plus cups of veggies per day is generally what I want them to be doing. That can feel like a really overwhelming number to an athlete who is not even getting one piece of fruit a day or. One vegetable a day. And So what? I encourage my families to do is start by adding one right so we can get one banana in a day. If we can get one apple in a day. If we can get one serving of spinach in a smoothie a day, that is a really big. And then if we can kind of start to build on that over time, it's huge. If your athlete is dealing with pickiness and just needs exposure to things working with a dietitian can be really helpful to kind of triage that. And often there's other support people that can. Help with those things too. Over consumption of fruits and vegetables does happen and often leads to underconsumption under consumption of total energy intake. So I typically see grains and fats being under consumed. If I'm seeing really large portions of fruits and veggies. So I'm talking like if an athlete's having a really big salad at lunch. Awesome. Glad you're getting lots of veggies in, but if you're not adding quinoa or beans or corn or rolls on the side to that, you're not getting enough carbs and it would be really hard to get enough calories out of that unless you're adding a lot of differe. Fats and those carbohydrates in. So it's all about balance, right? So too much fruits and veggies can actually be a bad thing for athletes. But at least getting that that 5:00-ish servings a day is what we're really trying to target. OK. Finally, I talk a little bit about supplements and then. We can open it up for questions from there. Supplement use in athletes young athletes is quite common. The the tricky thing with supplements is that supplements are not regulated in the United States. And so if you pick up a supplement label and you're not seeing any of these additional little marks that I I have added to my slide on there, there is no way to tell if what is on the label of that supplement is actually what's in the product. When independent research studies have been done on supplements, something of the tune of like 80% of supplements are outside of the 10% recommendation from what's on the label to what's actually in the product. And there's a high amount of contamination in three types of supplements specifically, which can be more commonly used in sport. Weight loss supplements tend to be more highly contaminated. Often we're finding. Medication called zybutramine in it, which is a weight loss medication in a supplement which may or may not be on the label. Muscle building supplements are often contaminated and can have pro hormones or other banned substances in them, and then sexual enhancement. Supplements are also often contaminated, so these are three highest risk categories of supplements. And as you can imagine, for young athletes, the muscle building supplement can be quite. Popular. So we need to make sure that we're being safe if an athlete is taking supplements. So my recommendation is always if an athlete's wanting to take something. Hopefully they're discussing it with their parent first. Or they need to be talking to their pediatrician. Or, better, a sports sports doctor. And if they can get a sports scientifician in conjunction with that, I think that can be really helpful because I find a lot of my sports M DS just haven't had the time to really dive into the world of sports supplements, which is a lot of my role. As a sports scientitian, So what we can do to be safer with these things is look for 3rd party verification. So those labels that you're seeing, the USP NSF, BSCG and information. Those are third party verification. So if you're at home, you have the luxury of grabbing your supplements from the cabinet. And you can start checking out the label to see what's on there. But if you're seeing one of these labels on your supplement, it means it's been sent to a third party. Verified that. What's on the label is actually what's in the product, so that is one safety net. And that's really, really helpful. The second safety net is. If it is verified, looking through and making sure there's no proprietary blends, that's often a way that. Ingredients are hidden on a label. Reading through the label and seeing. Are there any band ingredients on there? Are there pro hormones? Are there? You know, NCAA banned ingredients on the label and I think that's where a medical professional can help to kind of tease out those things. But this is a really good place to start if your supplement doesn't have one of these labels, don't purchase it. To be perfectly honest, and you just don't know that you're actually getting anything out of that product and you don't know that you're not getting anything that you. Don't want. In that product, the list that I have here is are common supplements that I see from my teen athletes. The three that I circled I think can be really valuable as long as they have that third party certification. A multi vitamin is the first one I think that. Can be a really nice kind of insurance for teen athletes who are very highly active and have very high nutrition needs. Carbohydrate supplements for more endurance athletes. I think those can be really useful and and necessary in that type of sport. And then omega-3, if you have an athlete who's really picky about eating fish or struggling with the the plant based sources of omega-3's, that can be another one to add in. Although I will say there are contraindications for Omega threes. So if your child does have any health history, any type of medical conditions, if they're taking any medications, it is really important to make sure you're checking with their doctor 1st to make sure that is an appropriate supplement for you to add. So don't just take my word for it. Please make sure you're talking to their doctor or schedule. Again an appointment with the dietitian who kind of helped can help to navigate that. The other supplements on this list, the ones that have been. Researched well, excuse me. For performance specifically include creatine and includes caffeine, beta alanine and sodium bicarbonate. Those have been researched mostly in adults, so I don't use them a lot in my teen population, and also because the amount of performance change we're seeing from those things is so small in comparison to what we can see from a. Total, Dieter. That I really want my athletes to know that they can eat normal foods and still meet their nutrition needs and still crush their performances, right? We can absolutely do that. These other things can be a little icing on the cake. Food puns are my favorite, but they can help in those really highest tier athletes who are competing. With like within tenths of seconds, right? That can make a difference, but we're really talking like that is the that's the difference, right? Tenths of a second and so overall where we're going to see the most performance changes is going to be from these larger scale dietary changes. So I will go ahead that, oh, I'm just going to do a little summary here just to kind of keep you in mind with all that information. So basically we're encouraging regular balanced meals for athletes. Three meals a day, one to three snacks a day. Definitely a snack before we exercise. Definitely a snack afterwards if if dinner or whatever meals going to be more extended. Three to five fruits and veggies per day for high calcium foods per day. Focus on foods with high iron content supplements. Make sure you've got third party verification, and ideally you're consulting with a pediatrician, a sports doctor, and or a dietician to make sure that you're safe in those choices that you're making. So thank you guys for having me and Julie. I'll open it up for any questions that might be available. Thank you, Amanda. Yes, if you guys have questions, please post them in the Q&A section so that she can answer them for you all. That was great, Amanda. Thank you. Or in the chat if you can't access the Q&A, you can also post it in the chat and then also we posted a survey too. And that's just really helps us with future pairing academies. And then the questions come up a few times about the slides. We will post the slides along with the recording in about a week on our District 20 website under the parent academies. But please just post if you have questions. Just put them either place in the chat or the Q&A if you have any questions for AM. We just have one that says thank you. Fantastic. Welcome. My kids have GI problems and we avoid. Sorry. Let me. I don't know if you can see that one. See it my kids have GI problems and avoid eating before competitions. Is this bad? Any way to provide food without upsetting the stomach? This is a tough situation and I do have a lot of athletes who experience that and I think it can be a combination of just the sensitivity within the kid. There could be other things that we need to address and then pre match pre race pre competition. Nerves can also play a role in that. It's not ideal for sure. I mean we we definitely get the most out of competitions when we're eating before them, so there can be a training effect that if we're eating a couple hours before and starting with something small like saltine crackers, right, we can start to train the gut to tolerate a. Little bit more I would probably recommend just because all of my kids with GI issues are different and tolerate different things. Seeing a sports psychician is helpful just because you can get specific recommendations, but we can train the guy. Ideally, we would train it so that we can tolerate something before competition and they will feel better and we might be able to actually improve their gut symptoms as well. OK. Next question. You're welcome, Amanda. You're welcome, Linda. S. Rusler. Yep, I love my wrestlers. Next question was, what about multivitamins? Should I look for a third party verification? Yes. So on multivitamins, you're going to see that USP symbol. So the black with the gold. But yes, they do have. You do want third party certification on those as well. They they are generally less risk. I will say, but I've seen multivitamins that have caffeine at it. I've seen multivitamins with herbal. And that study I was quoting about the 80% misinformation on the label that was specifically in, in supplements that have herbal ingredients. So I would definitely look for USP on multis. Dance teacher struggling with athletes avoiding eating. Are there some quick comments or conversations I can have with them to encourage proper fueling? Yes, we also do presentations for dancers and dance athletes as well. So if you need someone else to come out a third party, talk more about it. We can also set that up as well, but I think generally letting them know these risk factors that we've talked about telling them what relative energy deficiency is telling them how that's going to impact their bones long term. I focus on a lot of things, but when an athlete is loving their sport so much, the thought of them going out of their sport because they land on their foot and they break their foot or they break a bone in their leg because their bone health is. Poor because they've been restricting food. That's pretty scary to most athletes, and they're not out for a short period of time. It's generally anywhere from 6 to 12 weeks, depending on the degree of the injury. So letting them know that that's impacting their bone health now and. Potentially as they grow older as well. I think that can be really motivating, but then I think also like demonstrating like how do we do this? I assume you're not a dietician, but like actually having someone who can say, OK, this is how we do this. Expressing concern to parents if you're noticing it in individuals so that they can get the help of a dietitian if there's more going on under the surface as. To why they're not eating a tough sport with the aesthetics with it. Question on sleep. How much sleep to get and should they be eating before bed? That's such a great question. I think the general recommendation for sleep for teen athletes is around 9 hours per night, which is so if they're not getting that much working towards getting closer to that amount. Should they be eating before bed is a tricky question. I think if it doesn't impact the athletes sleep, I have no problem with them eating before bed. My question is if they're starving right before bed. They probably haven't eaten enough throughout the rest of the day, and so the goal would be yes on that day, eat before bed, like get adequate energy intake for the day, and let's also make an adjustment the next day so that we can get more fuel in at. More productive times during the day, but eating right before bed, especially if their exercise is later in the day. That still acts as a refuelling period. We we have a heightened absorption response to food for about four hours, four to six hours after exercise. And so they're still getting that and absorbing it really well and incorporating into their tissues well. So don't be afraid that them eating that is going to waste. It's not going to waste, but we can probably time it a little bit more efficiently so they're not so starving right before bed. Stands on MMCMCTI think oil and how to incorporate into an athlete. Sorry, MCT oil is. It stands for medium train chain triglyceride and it's typically found in coconut based products. So like the coconut oil is a rage for more endurance type athletes that specific fat can be absorbed directly through the stomach wall as opposed to going through what we call the portal system. Through the small intestine and so it's absorbed and it can be used as an energy source pretty immediately. So it's nice for endurance athletes because they can use that in conjunction with their carbohydrate intake. And fatty acids floating around in their bloodstream too. I don't use it a lot with my teen athletes because most of them are not at that level of endurance athletics like they're not doing half marathons typically or marathons, and that's usually the distance where I'll start using it more. If an athlete wanted to incorporate in some. Coconut, like coconut flakes, coconut oil into like a Curry dish or things of that nature. I support them adding it in that way, but I'm not using like a specific MCT oil as a supplement adding in. And then the question is thoughts on protein drinks and bars? So there can be a wide variety of these products. Some of them are classified as food, some of them are going to be classified as a supplement. So I would first look at the label and see does it have a nutrition facts label or does it have a supplement facts label? If it has a nutrition facts label, it's been labeled as a food. So again, what we see on the product should be what's in the product. If it's a supplement fax, we need to be looking for 3rd party verification. Generally, when I'm looking for protein drinks and protein bars. The place that I'm using those is for convenience, right? So we may be adding protein to a smoothie in the morning because the athlete is like running out the door needs a source of protein and they're smoothie and maybe they don't like Greek yogurt or whatever the reason is or protein bars for like a fast something in. The middle of the day can be helpful. But adding it in if the athlete's diet is already pretty varied and adequate in protein sources, I don't think it's necessary, but I think it can be a convenient option. And then the next question is, are there different nutrition recommendations for a child athlete with delayed growth? That's not related to growth hormone deficiency. So this can be a byproduct of that relative energy deficiency in sport that I was talking about earlier. So we're just not providing enough calories in order to support normal growth in the athlete. And so that's generally what I'm looking for, as well as micronutrients that contribute to growth. Low iron stores those things of that nature. An adequate protein intake and just kind of adequacy of the diet. So I would say yes, nutrition plays a role in that. And so if you haven't seen a dietitian seeing someone who specializes either in sport for your athlete or. In growth like we have a gap clinic in at Children's Hospital and they're really good at being able to determine where the deficiency is and what could be impacting that growth. Any other questions before we wrap up? That might be. OK. Well, just once again, if you haven't played the survey, please complete the survey. That really helps us with future ideas. And like I said at the beginning, Children's Hospital is phenomenal with us with partnering with us and offering all these parent academies. So thank you again, Amanda. We appreciate you so much doing this. This was fantastic. Thanks for having me. Best of luck to all of you guys out there feeding your kids. Thank you. Yeah. Have a good day. Have a good night everybody. Thank you for joining us.
