Fueling Youth and Adult Athletes: Tailored Nutrition for Performance, Growth, and Recovery

Athletes of all ages need a well-rounded diet to perform their best. However, the nutritional needs of youth athletes differ from those of adults due to growth, energy storage limitations, and developmental factors. Here’s a look at what each group needs to fuel optimally, including macronutrients, hydration, and the timing of meals.

Why Youth and Adult Athletes Have Different Needs

Youth athletes have increased energy demands due to rapid growth and a higher energy cost for physical activity. They also have lower glycogen storage and rely more on fat as a fuel source at the same exercise intensity as adults. For these reasons, youth athletes need frequent refueling and a careful balance of carbs, proteins, and fats to support both growth and athletic performance.

Did you know? Studies indicate that up to 30% of young athletes may not meet recommended daily caloric intake, leading to Relative Energy Deficiency in Sport (RED-S), a condition that affects performance, recovery, and long-term health.

Adults, on the other hand, generally have higher glycogen storage capacity and more stable metabolic rates, meaning their needs for fueling and recovery differ, especially around high-intensity or endurance activities.

Carbohydrates: The Body’s Primary Fuel

Carbohydrates are essential for both youth and adult athletes, but amounts vary based on age, sport, and training intensity. Carbs replenish glycogen stores, offering quick energy during high-intensity activities.

• Youth Athletes: Aim for 2.7–4.5 grams per pound of body weight daily if training multiple hours a day. Youth should consume simple carbs (like fruits) 30–60 minutes before a workout for quick energy and focus on complex carbs (whole grains, vegetables) throughout the day.
• Adult Athletes: Adults typically need 1.4–3.2 grams per pound of body weight daily, depending on training volume and intensity. Endurance athletes or those in multi-hour sessions may need up to 4.5 grams per pound on peak days. Ideally, have a balance of simple carbs both pre and post training, and rely on complex carbs throughout the day for sustained energy.

Did you know? About 25% of endurance athletes report failing to consume the recommended carbohydrate intake, which is linked to reduced endurance and faster onset of fatigue. Inadequate carbohydrate intake can increase injury risk by up to 30%, especially in team sports where muscle fatigue and focus are critical.

Tip: Both groups benefit from carbs post-workout to restore glycogen, ideally combined with protein to accelerate recovery. Examples include a fruit smoothie with Greek yogurt or oatmeal with almond butter.

Protein: Essential for Growth and Repair

Protein helps repair and build muscles and supports growth in youth. Both groups need regular protein intake, but young athletes especially need it to support growth on top of muscle repair.

• Youth Athletes: Require about 0.6–1 gram per pound of body weight daily. Aim to spread protein evenly across meals. Good options include lean meats, eggs, and plant-based proteins like beans and quinoa.
• Adult Athletes: Require around 0.8–1.2 grams per pound daily. Focus on 20–40 grams post-training to maximize muscle repair and synthesis. Foods like chicken, fish, and dairy are excellent options, but plant-based athletes can reach goals with tofu, lentils, and nuts.

Did you know? Nearly 40% of athletes do not meet protein intake guidelines, especially those engaged in high-intensity or frequent training. Inadequate protein intake is associated with a 15–20% higher risk of musculoskeletal injuries, emphasizing the importance of meeting daily protein needs.

Fats: For Sustained Energy and Recovery

Healthy fats are crucial for energy, especially during endurance activities. Fats also support brain health, hormone balance, and reduce inflammation.

• Youth Athletes: Youth generally need about 25–30% of daily calories from fats. Foods like avocados, nuts, olive oil, and fatty fish (for Omega-3s) are excellent choices for recovery and brain health.
• Adult Athletes: Can benefit from a similar fat intake (around 20–30% of daily calories), emphasizing unsaturated fats for anti-inflammatory benefits. Include options like salmon, flax seeds, and walnuts regularly to aid in recovery.

Adjusting Macronutrients Based on Goals and Type of Sport

The amounts and ratios of carbohydrates, proteins, and fats vary not only by age but also by individual goals and type of sport. Different sports place unique demands on the body, whether it’s endurance for distance running, power for weightlifting, or agility for team sports. Here’s a quick guide on how macronutrient needs shift with different objectives and sports:

• Weight Loss: For athletes aiming to lose weight, protein intake is generally increased (around 30–35% of total calories) to preserve muscle mass, while carbohydrates are slightly reduced (to about 25–30% of calories) to create a calorie deficit. Fats remain moderate (30–35%) to support satiety and energy levels without sacrificing nutrient density.
• Muscle Gain and Strength Building: When building muscle, athletes need higher protein (25–30% of calories) to support muscle repair and growth. Carbohydrates are also kept relatively high (40–50%) to fuel training sessions and optimize recovery. Fats make up the remaining 20–25% of total calories, supporting hormone health crucial for muscle growth.
• Endurance and Performance: Endurance athletes, such as runners or cyclists, benefit from a higher carbohydrate ratio (50–60% of total calories) to maintain long-lasting energy. This ratio supports glycogen stores, prevents fatigue during prolonged exercise, and aids in muscle repair. Protein (20–25%) and fats (20–25%) also play vital roles in recovery and sustained energy.
• Strength and Power Sports: Athletes focusing on strength or power, like weightlifters or sprinters, benefit from a higher protein intake (25–30%) to aid muscle repair and development, combined with moderate carbs (40%) and fats (30%) to fuel short bursts of intense activity.

Balancing macronutrients with specific goals and sports in mind helps athletes tailor their diets to match unique performance demands and health objectives.
