What is a common reason for performance issues in runners related to nutrition?

Improper fuel intake is a common reason for performance issues in runners because the body relies on carbohydrates, proteins, and fats to provide the necessary energy for training and competition. Carbohydrates are particularly important for endurance athletes, as they provide quick and accessible energy during prolonged physical activities. If a runner does not consume enough carbohydrates, they may experience fatigue, decreased performance, and slower recovery times. Additionally, inadequate protein intake can hinder muscle repair and recovery, while improper fat consumption can affect overall energy levels.

When runners fail to fuel adequately before, during, or after their runs, they might not meet their nutritional needs, leading to decreased performance and potential health issues. Maintaining a balanced diet that aligns with an athlete's training demands is crucial for optimizing performance, reducing the risk of injury, and ensuring overall health and longevity in the sport.
