The body compensates for muscle endurance during fatigue by utilizing different energy sources and adjusting movement strategies. Initially, it relies on stored ATP and creatine phosphate, but as fatigue sets in, it shifts to aerobic metabolism, using fatty acids and glucose. Additionally, the nervous system may alter movement patterns to recruit different muscle fibers for continued activity. This adaptation, while efficient, can lead to muscle strain or imbalance if proper form is not maintained, highlighting the importance of listening to the body’s signals.
