<h2>Planning Balanced Meals</h2>
<p>When creating a meal plan for young athletes, it is important to focus on balanced meals that include a variety of food groups. A typical meal should consist of the following:</p>

<ul>
    <li><strong>Carbohydrates:</strong> Whole grains, fruits, and vegetables provide essential energy.</li>
    <li><strong>Proteins:</strong> Lean meats, poultry, fish, eggs, dairy products, and plant-based proteins like beans and lentils.</li>
    <li><strong>Fats:</strong> Healthy options such as avocados, nuts, seeds, and olive oil.</li>
</ul>

<p>Incorporating these elements into each meal can help maintain energy levels and support recovery after exercise.</p>

<h2>Meal Timing and Frequency</h2>
<p>The timing of meals and snacks is as important as the food itself. Young athletes should aim to eat small meals every 3 to 4 hours to maintain energy levels throughout the day. A good schedule might include three main meals and two to three snacks. Eating a balanced breakfast within an hour of waking up kickstarts metabolism and provides energy for morning activities.</p>

<figure id="figure-g0m685errmbfffl49"><img id="g0m685errmbfffl49" src="https://media.gettyimages.com/id/838410218/photo/kid-eating-healthy-breakfast.jpg?b=1&s=2048x2048&w=0&k=20&c=nwva6bX2Y8HNtkOun1kLLOyMIhm4eCcfnet8p0F0alE=" alt="young athlete breakfast" class="object-cover bg-gray-100" style="aspect-ratio: 16/9"></figure>

<p>Pre- and post-workout nutrition is also vital. A snack or light meal containing carbohydrates and protein consumed 1 to 2 hours before exercise can help sustain energy levels. Post-workout meals should be consumed within 30 to 60 minutes after exercise to replenish glycogen stores and support muscle recovery.</p>

<h2>Hydration: An Essential Component</h2>
<p>Proper hydration is critical for young athletes, as even slight dehydration can impair performance. Encourage kids to drink water regularly throughout the day, not just during physical activity. The amount of water required can vary depending on the individual's size, activity level, and environmental conditions.</p>

<p>A good rule of thumb is to drink at least half their body weight in ounces per day. During intense training or competition, sports drinks may be helpful to replace electrolytes lost through sweat.</p>

The Ultimate Guide to Hydration for High School Athletes

<h2>Performance in Temperature: How Physical Operations Vary in Different Settings</h2><h3>Colder Temperatures</h3><p><strong>Metabolic Changes:</strong></p><ul><li>Exposure to colder temperatures, around 10-16˚C (50-60˚F) increases metabolic rate due to shivering and thermoregulation demands as your body works to regulate its temperature in an cooler outside environment. As metabolic rate increases, more energy - from food and water - is expended/used, meaning that many athletes may require more carbohydrates and calories to sustain peak performance.<ul><li>One solution to making sure energy is sustained is by layering clothing—such as jackets, gloves, and thermal pants—to help maintain a stable core body temperature. Layering traps body heat and prevents excessive energy loss or shivering, allowing muscles to stay warm and reducing the risk of stiffness or injury.&nbsp;</li><li>Eating warmer foods in colder temperatures, like soup 1–2 hours before a race, can help maintain core body temperature and reduce the onset of shivering. A heated, carbohydrate-rich meal not only provides quick energy but also supports thermogenesis, making it easier for the body to focus energy on performance rather than temperature regulation.&nbsp;</li></ul></li></ul><p><strong>Hydration Risks</strong>:</p><ul><li>Cold weather can blunt thirst cues—making individuals feel less inclined to drink water. Because the mouth usually does not feel dry and the physical signs of dehydration are less noticeable in cooler temperatures, athletes may underestimate their hydration needs. The risk of dehydration remains significant in cooler weather due to continued fluid loss through respiration, sweat, and other metabolic processes—even if it is less noticeable.<ul><li>Proactive hydration—drinking water consistently throughout the day rather than waiting 30 minutes before or during exercise—can significantly support an athlete’s performance in cooler temperatures by maintaining optimal blood flow, regulating internal body temperature, and preventing the hidden effects of dehydration that often go unnoticed in the cold.</li></ul></li></ul><p><strong>Injury Risks</strong>:</p><ul><li><p>In colder environments, muscles are often found to be stiff and more prone to injury, especially as the body prioritizes maintaining core temperature, which can lead to reduced blood flow to the extremities, especially muscles. This can cause muscles to become stiff and less flexible, making them more prone to strains, tears, or pulls during physical activity. The reduced elasticity and flexibility can increase the likelihood of muscle strains or tears during explosive movements like sprints or jumps.</p></li><li><p><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">As the body attempts to keep warm in cooler environments, shivering may occur, causing involuntary muscle contractions. Although shivering helps generate heat, the energy it uses can also cause muscle fatigue and reduce the efficiency of muscle contractions, making the muscles more prone to strain or injury.</span></p><ul><li><p><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Proper Warm-Up: Ensure a comprehensive warm-up that includes dynamic stretches, light jogging, and joint mobility exercises to prepare the body for the physical demands of exercise. Consider starting with a few minutes of light activity in a sheltered, warmer area if possible.</span></p></li><li><p><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Layering Clothing: Wear appropriate clothing layers to keep muscles warm. This includes moisture-wicking materials, thermal clothing, and insulating layers like gloves, hats, and socks to prevent heat loss. Thermal gear can help maintain core body temperature and reduce the risk of stiffness or injury.</span></p></li><li><p><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Gradual Intensity: Start workouts or exercises at a lower intensity to allow muscles to gradually adjust to movement.

Take regular breaks, and if conditions worsen, seek shelter and warmth.&nbsp;</span></p><p><br></p></li></ul></li></ul><h3>Hotter Temperatures</h3><p><strong>Core Temperature and Performance</strong></p><ul><li>Hot environments elevate core body temperature quickly as the body works - using water, energy, etc. - to cool itself down, which can reduce endurance performance due to early fatigue, dehydration, and overheating.<br><ul><li>&nbsp;A ~1°C rise in core body temperature before exercising in the heat significantly reduced endurance performance in the morning but not in the evening. This means that even a small increase in internal body temp—like from staying out in the sun, warming up too aggressively, or wearing too many layers—can cause fatigue to set in earlier during workouts or competitions if they’re in the morning.&nbsp;</li><li>Don’t sit in the sun, wear thick layers, or take hot showers right before morning practice or races. Consistent exposure to these condtitions increases core temperature, makes it harder to cool off before a practice/performance, and does not work your muscles in the direct way a warm-up lap or dynamic exercises would.<br></li><li>Use a cold towel on your neck, drink icy water, or stay in air-conditioned spaces close to the time of warm-up. Maintaining a cooler body will decrease core temperature and allow you to operate at your best.</li><li>A cold, carb-rich snack (like fruit, oatmeal, or toast) can support energy without warming your core further. &nbsp;<span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">When you eat before a workout, your body begins digesting food—this process raises your internal body temperature, especially with large or heavy meals. Choosing to avoid adding extra heat from digestion by comsuming foods with less required digestion will help.</span><br><br>Drink cool water or an electrolyte drink in small sips starting 1–2 hours before exercise. Hydration will allow your body to cool itself down</li></ul></li></ul><p><strong>Hydration</strong>:</p><ul><li>Increased Sweat Loss<ul><li>Study: Cheuvront &amp; Kenefick (2014) found that in hot environments, sweat rates can exceed 1–2.5 liters/hour, even in moderate activity.</li><li>Athletes lose fluids faster than they can drink, especially during high-intensity or prolonged exercise, increasing risk of dehydration, especially if pre-exercise hydration is poor.</li></ul></li><li>&nbsp;Delayed Thirst Response<ul><li>Study: Sawka et al. (2007) observed that the body's thirst mechanism lags behind actual fluid loss in the heat.</li><li>Athletes often underestimate how much water they need and don’t feel thirsty until they’re already dehydrated by 1–2% of body weight.</li></ul></li><li>Cognitive Performance:<ul><li>Extreme heat and cold can stress the body and distract the mind, while moderate temperatures allow for clearer thinking and better concentration during exercise or competition.</li></ul></li><li>&nbsp;Performance Drops with Mild Dehydration<ul><li>Study: Casa et al. (2010) found that just 2% dehydration can impair endurance performance, increase perceived effort, and elevate core temperature.</li><li>Even mild dehydration leads to early fatigue, slower running times, and increased risk of heat illness.</li></ul></li><li>&nbsp;Electrolyte Imbalance Risks<ul><li>Study: Bergeron et al. (2005) studied youth athletes and noted that excessive sweating in hot, humid environments without electrolyte replacement led to muscle cramps and performance decline.</li><li>Water alone may never be enough—sodium and potassium, common electrolytes, must be replenished, especially during longer sessions or repeated training days.<ul><li>Prehydrate: Start hydrating the night before and drink 16–20 oz of fluid 1–2 hours before exercise in heat.</li><li>Drink during workouts: Aim for 6–8 oz every 15–20 minutes, or more if sweat rate is high.</li><li>Use electrolytes: Choose a sports drink or add salt to water during long/hot sessions.<br></li><li>Monitor urine color: Pale yellow = hydrated. Dark = drink more water.</li><li>Cool your fluids: Cold drinks are absorbed faster and help reduce core temperature.</li></ul></li></ul></li></ul><h3>Indoor Training and Dry Atmospheres</h3><p><strong>Humidity</strong>:</p><ul><li>Performance Optimization: Training and competing in environments with lower humidity has been proven, by multiple studies, to help maintain endurance performance, especially in hot conditions.​</li><li>Thermoregulation: Lower humidity facilitates more effective sweat evaporation, meaning that the sweat used to cool the body down evaporated effectively, aiding the regulation of body temperature regulation during exercise.​</li><li>A study by Cheuvront et al. (2008) found that fluid loss in low-humidity environments (20-30%) could still lead to significant dehydration, particularly in endurance events. Despite better evaporative cooling in these conditions, the performances of athletes who didn’t consistently rehydrate with fluids were impared due to early fatigue and reduced performance.<ul><li>Hydration Strategies: Even in low-humidity environments, athletes should monitor hydration levels, as sweat evaporation can lead to significant fluid loss without the sensation of being overly sweaty.​ Consuming 16-20oz of water 2-3 hours before an exercise/training session can ensure proper hydration</li><li>Electrolyte Drinks: In dry environments, athletes sweat out important electrolytes (sodium, potassium, magnesium). Drinking sports drinks containing electrolytes or using electrolyte tablets can help maintain fluid balance, prevent cramping, and avoid fatigue.</li><li>Post-Exercise Hydration: After exercise, it's important to rehydrate with both water and electrolytes to replenish the fluids lost during the workout. Drinking water or electrolyte drinks within the first 30 minutes after exercise can enhance recovery.</li><li>Carbohydrate-Rich Foods: For long training sessions or races, athletes should consume carbohydrates before and during exercise to help maintain energy levels and support hydration.

Performance in Temperature: How Physical Operations Vary in Different Settings

<h3>The Importance of Drinking Water</h3><p>We all know that humans need water to live. It is essential for many bodily functions that provide the body with energy: maintaining homeostasis, regulating body temperature, and supporting cellular respiration. Without water, the average human can only survive a few days. However, many people overlook just how much water they should be drinking daily, especially high school athletes. Hydration needs vary depending on factors such as age, environment, activity level, and overall health, making it especially critical for high school athletes to understand their unique requirements.</p><p><strong>The Impact of Dehydration on Performance</strong><br>Dehydration has been linked to a decline in athletic performance. A study published in Frontiers in Physiology (2021) found that dehydration significantly impairs endurance, strength, and cognitive function in athletes (PMC8625246). This is particularly concerning for high school athletes who often participate in intense training sessions and competitions. Even mild dehydration—defined as a body mass loss of 1-2% due to fluid deficits—can reduce aerobic performance and increase notable exertion/effort. When athletes ar dehydrated, their blood volume decreases, and, as a result, the oxygen delivery to muscles is reduced and&nbsp;they experience an overall decline in efficiency.</p><p><strong>Increased Risk of Injury and Muscle Damage</strong><br>Hydration plays a crucial role in preventing injuries. A Sports Medicine study (2021) found that dehydration leads to impaired neuromuscular control and an increased likelihood of musculoskeletal injuries in athletes (PMC8566643). Muscle fibers and tendons rely on water to maintain their structural integrity and function, as it helps keep the proteins and connective tissues within muscles hydrated and replenished. Proper hydration also supports the production of synovial fluid, which lubricates joints and reduces friction. When you're well-hydrated, your muscles can contract and relax more efficiently, maintaining their elasticity and reducing stiffness. On the other hand, dehydration leads to a decrease in intracellular and extracellular fluid, making muscle fibers more rigid and prone to microtears, strains, and cramps. Additionally, inadequate fluid intake can lead to a higher risk of heat-related illnesses such as heat cramps, heat exhaustion, and heat stroke—conditions that can be life-threatening if not properly managed.</p><p><strong>Hydration and Liver Health</strong><br>While dehydration is commonly associated with muscle cramps and fatigue, it also has systemic effects, including liver dysfunction. A study in the International Journal of Molecular Sciences (2021) highlights how dehydration can induce oxidative stress and inflammation in the liver, potentially leading to long-term damage (PMC8566439). Since the liver plays a key role in detoxifying the body and metabolizing nutrients essential for recovery, dehydration-induced liver stress can hinder an athlete’s ability to recover from training and maintain optimal health.</p><p><strong>Hydration and Cognitive Function</strong><br>Beyond its physical effects, dehydration has significant consequences on cognitive function, reaction time, and mental clarity. A study published in Nutrients (2017) found that even mild dehydration (1-2% body weight loss in fluids) can impair short-term memory, concentration, and decision-making skills in athletes (PMC5640004). In high school sports, where split-second decisions, coordination, and focus are crucial, even slight dehydration can put an athlete at a disadvantage.</p><ul><li><strong>Reduced Cerebral Blood Flow:</strong> The brain is highly sensitive to fluid balance. When dehydration reduces blood volume, cerebral perfusion (blood flow to the brain) is decreased. Studies that have used functional MRI scans (fMRI) have shown that hypohydration (a state of dehydration) leads to decreased activity in regions associated with attention, memory, and executive function(D’Anci et al., 2009). With less blood flow, reaction times are slower, motor coordination is imparies, and mental fatigue is increased—all detrimental to athletic performance.</li><li><strong>Electrolyte Imbalance and Neural Communication:</strong> Hydration is essential for maintaining electrolyte balance, particularly sodium, potassium, and chloride, which play a role in regulating neuronal signaling and synaptic transmission. When you are dehydrated, electrolyte imbalances alter the electrical activity of your neurons, leading to slower nerve conduction and impairments in focus, decision-making, and motor control. This is particularly dangerous in sports requiring rapid reflexes and precision, such as sprinting, basketball, or soccer.</li><li><strong>Increased Cortisol and Perceived Stress:</strong> Dehydration elevates levels of cortisol, a stress hormone that negatively affects cognitive performance, emotional stability, and memory recall. In high school athletes, increased cortisol due to dehydration can contribute to poor mental resilience under pressure, making it harder to stay composed in competitive settings.</li><li><strong>Neurotransmitter Disruption:</strong>&nbsp;<p><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Dehydration alters neurotransmitter activity and affects cognitive performance, mood regulation, and mental endurance. It indicates that dehydration can lead to lower dopamine and serotonin availability, contributing to increased fatigue, reduced motivation, and impaired mental performance—all of which are critical for high school athletes. (Cian et al., 2019, PMC8566439). </span><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Athletes experiencing dehydration often report feeling more fatigued, less motivated, and more irritable, which can decrease competitive drive and focus.</span></p></li><li><strong>Blood-Brain Barrier Permeability and Neuroinflammation:</strong> Severe dehydration has been linked to increased permeability of the blood-brain barrier (BBB), allowing harmful substances and inflammatory markers to enter the brain more easily (Zhang et al., 2015). This can trigger neuroinflammation, which may contribute to brain fog, slowed cognition, and prolonged recovery times after physical exertion.<br><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);"><br>Results from cognitive impariments:</span><br></li></ul><ul><li>Slower reaction times, leading to delayed responses in fast-paced sports.</li><li>Decreased focus and coordination, increasing the risk of errors and poor performance.</li><li>Poor memory recall and decision-making, affecting strategic gameplay and split-second choices.</li><li>Increased mental fatigue, making it harder to sustain performance over long training sessions or competitions.</li></ul><p><strong>How Much Water Should High School Athletes Drink?</strong><br><br>There is no universal hydration guideline, everyone's bodies have different needs and what might work for one person may not work for the other. However general recommendations suggest that high school athletes should:</p><ol><li>Drink at least 2-3 liters (70-100 oz, 8-12 cups) of water throughout day with increased intake during strenuous exercise.</li><li>Follow the The American College of Sports Medicine guidelines, which reccomend consuming 16-20 ounces of water 2-3 hours before exercise, 8-10 ounces every 15-20 minutes during activity, and replace lost fluids post-exercise. Electrolyte-rich drinks may be beneficial for prolonged workouts, especially in hot conditions.</li><li>Consider adding electrolytes to water, or consuming eletrolyte drinks, especially for prolonged workouts, even more so in hot and humid conditions, when water loss is greater.</li></ol><p><strong>References:</strong></p><p>Cian, Christophe, et al. “Influence of Variations in Body Hydration on Cognitive Function: Effects of Hyperhydration, Heat Stress, and Exercise-Induced Dehydration.” Frontiers in Physiology, vol. 10, 2019, p. 1046, <a href="https://doi.org/10.3389/fphys.2019.01046" data-mce-href="https://doi.org/10.3389/fphys.2019.01046">https://doi.org/10.3389/fphys.2019.01046</a>.<br><br>Mecocci, Stefano, et al. “Cognitive Performance and Dehydration: A Systematic Review and Meta-Analysis.” Nutrients, vol. 13, no. 7, 2021, p. 2186, <a href="https://doi.org/10.3390/nu13072186" data-mce-href="https://doi.org/10.3390/nu13072186">https://doi.org/10.3390/nu13072186</a>.<br><br>Pérez-González, Alba, et al. “Impact of Dehydration on Cognitive Performance: A Comprehensive Review.” Frontiers in Psychology, vol. 12, 2021, p. 704217, <a href="https://doi.org/10.3389/fpsyg.2021.704217" data-mce-href="https://doi.org/10.3389/fpsyg.2021.704217">https://doi.org/10.3389/fpsyg.2021.704217</a>.<br><br>Zhang, Yufen, et al. “Effects of Hydration on Neurotransmitter Systems: Implications for Cognitive Function and Mental Performance.” Journal of the International Society of Sports Nutrition, vol. 18, no. 1, 2021, p. 85, <a href="https://doi.org/10.1186/s12970-021-00479-5" data-mce-href="https://doi.org/10.1186/s12970-021-00479-5">https://doi.org/10.1186/s12970-021-00479-5</a>.<br></p><p>Lee, Elaine C., et al.

I am building a blog/website where I post articles going into details about fueling as a high school athlete, including rest, food, hydration, and their impacts on performances, muscle memory, and how they work for your body and impact you as an athlete. I plan to discuss what athletes should stop doing, promote healthier eating and drinking habits, and explain the biology behind it. I plant to publish articles that discuss these issues on this website.
