What is central command fatigue?

Central command fatigue refers to a decrease in the brain's ability to generate and sustain the effort required for physical activity, often experienced during prolonged exercise or intense physical exertion. This phenomenon is linked to a reduction in the motivational signals sent from the brain to the muscles, which can result in feelings of exhaustion and decreased performance. Factors such as mental fatigue, dehydration, and energy depletion can contribute to central command fatigue. It highlights the complex interplay between physical and mental factors in endurance activities.
