The answer is the fourth one (d): CHO - rich foods.
Explanation for each option:
a) Fat - rich foods: While fats are an important part of a balanced diet, they are not ideal for a pregame meal. Fats take longer to digest, which can lead to discomfort during physical activity.
b) Fiber - rich foods: Fiber is important for digestive health, but consuming high-fiber foods right before a game can cause gastrointestinal distress, as they also take longer to digest.
c) Protein - rich foods: Proteins are essential for muscle repair and growth, but they are not the primary source of quick energy needed for athletic performance. They also take longer to digest compared to carbohydrates.
d) CHO - rich foods: Carbohydrates (CHO) are the body's primary source of quick energy. A pregame meal rich in carbohydrates helps to maximize glycogen stores in the muscles, providing the energy needed for optimal performance during the game.
In summary, a pregame meal should focus on providing plenty of fluids and calories primarily from carbohydrate-rich foods to ensure the body has the necessary energy for athletic performance.
