Athletes must focus on hydration, carbohydrate intake, and electrolyte balance during competition. Sufficient energy levels are essential for peak performance, so consuming complex carbohydrates before events can provide sustained energy. After competition, protein aids in muscle recovery. Additionally, avoiding heavy or hard-to-digest foods close to competition time can prevent gastrointestinal issues. Timing meals strategically and ensuring immediate post-competition nutrition helps optimize recovery, making these considerations crucial for athletic success.
