Nutrient Intake for Active Adolescents: A Practical Guide

about us banner image

Adolescence is a powerful stage of growthand development. For active young athletes, especially swimmers, nutritionplays a central role in fuelling performance, supporting recovery, andpromoting long-term health and resilience.

At Swimmers Clinic, we guide young athletesand their families in building strong, evidence-informed nutrition habits.Here’s what matters most:

1. 🥩 Protein: Building and Repairing

Protein supports muscle repair, recovery,and strength gains—especially important during growth spurts and regulartraining.

✔ Recommended Intake: 1.2–2.0 g per kg ofbody weight, depending on training intensity.

• Choose quality sources: Lean meats,poultry, eggs, dairy, fish, tofu, lentils, and beans.

• Spread it out: Include protein in allmeals and snacks—not just dinner.

• After training: Combine protein withcarbohydrates (e.g., smoothie, sandwich, yoghurt + fruit). For longer orhigh-volume sessions, carbs may take priority post-training.

2. 💧 Hydration: A Daily Non-Negotiable

Hydration supports cognitive focus,thermoregulation, performance, and recovery. Active adolescents can losesignificant fluid through sweat and must learn to hydrate proactively.

• Before training: Begin well-hydrated(urine should be pale yellow).

• During training: Sip water regularly. Forlonger sessions, consider adding electrolytes—not sugary sports drinks, whichoffer little nutritional value.

• After training: Rehydrate with water,milk, or foods high in water content (e.g., fruits, soups).

Note: We do not recommend high-sugar drinksfor young swimmers. Our advice focuses on tailored hydration strategies basedon session intensity and recovery needs.

3. ⚙️ Micronutrients: Supporting Growth & Immunity

Micronutrients don’t just "topup" health—they drive growth, bone strength, and immune defence.

• Calcium & Vitamin D: Prioritisedairy, fortified drinks, leafy greens, and regular sunlight exposure.

• Iron: Especially important for adolescentgirls. Include lean red meat, beans, lentils, fortified cereals, and VitaminC-rich foods to improve absorption.

• Antioxidants: Berries, peppers, spinach,and other colourful fruits/veg protect against training-related oxidativestress.

4. 🥗 Balance: The Foundation of Performance

A well-balanced diet supports both dailyfunction and training adaptation. Avoid restrictive eating patterns, andprioritise whole, minimally processed foods.

• Carbs = Energy: Whole grains (oats,quinoa, brown rice) support sustained performance.

• Healthy fats = Fuel: Avocados, olive oil,nuts/seeds, and oily fish boost brain and heart health.

• Hydrating foods: Add cucumbers, oranges,melons, and soups to support fluid intake.

💬 Final Thoughts

Nutrition is more than fuelling thebody—it’s an investment in a swimmer’s future.
