Explain why a games player requires carbohydrates and protein in their diet.

Carbohydrates and protein are crucial for any athlete, especially a games player who performs a mix of high-intensity sprints and endurance work. Carbohydrates are the primary fuel source, broken down into glucose and stored as glycogen. Depleting glycogen stores leads to fatigue. Protein is made of amino acids, the building blocks for tissue. After exercise, protein consumption is vital to initiate muscle protein synthesis, repairing the damage caused during the game and leading to adaptation and strengthening.
