The athlete’s diet should consist of..
45 to 65% from carbohydrates
15 to 25% from protein
20 to 35% from fat.
Carbohydrates – Roles carbs play in providing
Energy
Glycogen Stores:
-Exercise breaks down glycogen to glucose, fuelling ATP production, the cell's energy
source.
-Adequate glycogen availability improves endurance and exercise performance.
-Low glycogen levels result in fatigue and reduced performance.
-Maintaining glycogen stores is crucial for optimal physical output.
Carbohydrates – Roles carbs play in providing
Energy
Enhanced Performance:
-Carbs before exercise boost performance
with quick energy.
-Especially important for activities lasting
over 60-90 minutes.
-Maintains vital glycogen stores during
prolonged workouts.
How Carbs help in Anaerobic and Aerobic Energy Production:
-Carbohydrates are crucial for anaerobic and aerobic energy production.
-In anaerobic activities like weightlifting, carbs are broken down without oxygen.
-Carbs remain important in aerobic exercises, such as running or cycling, especially at higher intensities.
-They contribute substantially to energy output in both types of activities.
Carbs role for recovery
-After exercise, consuming carbohydrates is important for replenishing glycogen stores and
promoting recovery.
The post-exercise period is when your body is most efficient at restoring
glycogen levels.
Glycogen restoration rates Post event glycogen intake high GI

Importance of glycogen replenishment after intense exercise.
Muscle Recovery and Performance:
-Replenishing glycogen after intense exercise helps muscles recover and maintains performance for future workouts.
Role of protein in muscle repair and recovery.
-Muscle protein synthesis is the process of using amino acids to repair and grow
muscle fibres.
-Right protein consumption supports muscle recovery and adaptation, leading
to improve performance.
-Proteins are composed of amino acids, the building blocks of muscle tissue.
Protein intake provides amino acids for repairing and rebuilding muscles
Protein sources
Lean meats: Chicken, lean beef, pork.
Fish: Salmon, tuna, (rich in omega-3s).
Eggs: Complete protein source, versatile.
Dairy products: Greek yogurt, cottage cheese, milk.
Plant-based sources: Legumes, tofu
protein on Post-Exercise Recovery:
Protein intake is crucial after exercise.
-Protein aids muscle repair and growth.
-Protein intake rebuilds muscles for future workouts.
