What principle emphasizes the gradual increase in training demands to improve performance?

The principle that emphasizes the gradual increase in training demands to improve performance is progression. This concept is fundamental in athletic training as it ensures that athletes can safely enhance their physical capabilities over time. By systematically increasing the intensity, volume, or complexity of their training, athletes can stimulate physiological adaptations that lead to improved strength, endurance, and overall performance.

Essentially, progression helps prevent plateauing, as well as reduces the risk of injury that can arise from sudden increases in training intensity. It encourages athletes to build upon their existing fitness levels rather than attempting to make rapid changes that their bodies might not be prepared to handle. This principle aligns with the body’s natural adaptation processes, where consistent and incremental challenges lead to enhanced performance capabilities.
