Disclaimer [ENGLISH]
Young athletes often try special diets and supplements to improve their athletic performance.
- Many of these products do not live up to their claims to increase strength, speed, and athletic skills.
- Dietary supplements are not tested and regulated like prescription drug products.
- Problems with safety, contamination, and quality are common with these products, even if purchased from a reliable source.
Rather than using supplements, athletes should focus instead on following the basics of proper hydration and sports nutrition. Both are crucial in supporting growth and athletic performance.
Protein
- Protein is essential for growth, energy, and tissue repair.
- Proteins contain the building blocks the body uses to recover after workouts and to repair injury.
- Athletic performance depends on muscle strength, and muscles are made of protein.
- Although athletes who are involved in strength and endurance training may need slightly more protein, it’s a mistake to think you can simply build up muscles by eating lots of protein.
- Exercise (specifically, strength training), not dietary protein, increases muscle mass.
- Athletes should be able to meet the need for more protein with a balanced diet instead of supplements.
- Protein intake should be spread throughout the day, especially in the 24 to 48 hours after a hard workout. A little bit of protein in the post-workout snack may also help with recovery.
- Good sources of protein include:
- Eggs/egg whites
- Low-fat dairy products like Greek yogurt or cottage cheese
- Lean meat (chicken, lean ground beef)
- Fish
- Edamame
- Beans
- Lentils
Carbohydrates
- Carbohydrates provide energy
- They contain the fuel the body needs to perform and also protect muscle tissue from breaking down.
- Athletes should have a carbohydrate-rich meal 3 to 4 hours before exercise and a high-carbohydrate snack about 1 hour before exercise.
- Good sources of carbohydrates include:
- Bread
- Bananas, apples, or other fruit
- Pasta
- Rice
- Beans
- Dried fruit
Examples of a post-workout snack
- Peanut butter and banana sandwich on whole wheat bread
- Smoothie (milk + fruit)
- Yogurt with berries
Hydration
- Don’t forget to stay hydrated!
- Athletes can lose body fluids very rapidly, so they must make sure they are always well hydrated.
- Thirst is not a good gauge of fluid needs and waiting until thirsty to drink can decrease athletic performance.
- Drink water during workouts, especially if longer than 45-60 minutes.
- Avoid sports drinks, which are high in sugar, unless working out for longer than 60 minutes.
