Sports Nutrition for Teenage Athletes: Fueling the Future

Sports nutrition is an essential component of any athlete’s training regimen. For teenage athletes, it becomes even more crucial as their bodies are still developing and require the right nutrients to support their growth and performance. In this context, sports nutrition refers to the science of consuming a balanced diet and nutritional supplements to optimize performance, support recovery, and reduce the risk of injuries. In this article, we’ll explore some useful tips and insights for teenage athletes to fuel their body with the right nutrition and achieve their athletic goals.

Understanding the Nutritional Needs of Teenage Athletes

Teenagers are an active group, participating in sports and other high-energy activities that require proper nutrition to support growth and development. For teenage athletes, this means consuming enough calories to fuel their activity level while also providing the necessary nutrients to support a healthy body.

Caloric Intake

On average, teenage athletes require around 2,500-3,000 calories per day, depending on their activity level and body composition. It is important to note that this number is just an estimate, and individual needs may vary.


Teenage athletes require a balanced intake of carbohydrates, protein, and fat to support their activity level. Carbohydrates are the body’s primary source of fuel and should make up around 45-65% of an athlete’s total caloric intake. Protein is important for muscle growth and repair and should make up around 10-30% of total caloric intake. Fat is necessary for hormone production and should make up around 20-35% of total caloric intake.

Hydration for Teenage Athletes

Proper hydration is essential for teenage athletes to perform their best and avoid dehydration-related health issues.

Key takeaway: Teenage athletes require proper nutrition to support their growth, development, and activity level. This includes consuming enough calories from a balanced intake of carbohydrates, protein, and fat, proper hydration, timing of meals and snacks, mindful eating practices, and meal planning with balanced and varied options. Individual needs may vary, and planning ahead can help ensure they have healthy options available when they need them.

Fluid Intake

Teenage athletes should aim to consume around 8-10 cups of fluid per day, with additional fluid intake before, during, and after exercise.

During exercise, the body loses electrolytes through sweat. Electrolytes are essential minerals that help regulate fluid balance in the body. Teenage athletes should consume foods and drinks that contain electrolytes, such as sports drinks or coconut water, to replenish lost electrolytes during exercise.

Timing of Meals and Snacks

The timing of meals and snacks is important for teenage athletes to ensure they have enough energy to perform their best during exercise.


Teenage athletes should consume a meal or snack that is high in carbohydrates and low in fat and fiber 2-4 hours before exercise. This will provide the body with enough energy to perform at its best without causing digestive discomfort.

During Exercise

During exercise, teenage athletes should consume carbohydrates in the form of sports drinks, gels, or snacks to maintain energy levels.


After exercise, teenage athletes should consume a meal or snack that contains carbohydrates and protein to help repair and rebuild muscle tissue. This will also help replenish glycogen stores in the body, which can be depleted during exercise.

Mindful Eating for Teenage Athletes

Mindful eating is a practice that involves paying attention to the food we eat and how it affects our body. This can be beneficial for teenage athletes in several ways.

Decreased Risk of Overeating

Mindful eating can help teenage athletes become more aware of their hunger and fullness cues, which can reduce the risk of overeating.

Improved Digestion

Eating slowly and mindfully can improve digestion and reduce the risk of digestive discomfort during exercise.
