What is a commonly cited contributing factor to the temporary muscle fatigue and soreness often experienced after intense physical exercise?

Explanation

A commonly cited contributing factor to the temporary muscle fatigue experienced during and after intense exercise is the buildup of lactic acid, or lactate, within the working muscles, which tends to accumulate more rapidly when muscles are working hard and demanding energy faster than the body can fully supply oxygen for typical aerobic energy production. As exercise intensity decreases and the body recovers, this accumulated lactate is gradually cleared and processed by the body. While lactic acid buildup has traditionally been closely associated with exercise-induced fatigue, modern exercise science recognizes that muscle fatigue is a complex process influenced by multiple additional factors as well.
