Muscle fatigue

Muscle fatigue is the decline in a muscle's ability to generate force, often due to intense or prolonged activity. It results from factors like lactic acid buildup, energy depletion, and impaired nerve signals. Runners experience muscle fatigue as a decrease in performance and increased risk of injury. Managing fatigue through proper training, nutrition, and rest is crucial. For example, marathon runners may experience fatigue in the later stages of a race, impacting their pace. Understanding and mitigating muscle fatigue helps runners maintain performance and reduce recovery time.
