Carbohydrate loading can benefit athletes before a competition by maximizing glycogen stores in muscles and the liver. This strategy involves increasing carbohydrate intake in the days leading up to an event, which helps sustain energy levels during prolonged physical exertion. By ensuring adequate glycogen availability, athletes can improve their endurance, performance, and overall race times. Carbohydrate loading is especially effective for endurance events lasting longer than 90 minutes, as it delays fatigue and enhances recovery. Proper execution requires careful planning and monitoring of dietary intake to achieve optimal results.
