Question

Quizplus · Accepted Answer

Fatigued muscle cells that recover rapidly are the products of intense exercise of short duration. This is because during intense exercise of short duration, the cells use anaerobic metabolism which produces lactic acid as a byproduct. Once the exercise stops, oxygen is available and the lactic acid is quickly removed by the body allowing for rapid recovery. Slow exercise of long duration may also cause muscle fatigue, but the recovery time is longer as it relies more on aerobic metabolism which produces less lactic acid. Intense exercise of long duration may cause severe muscle fatigue and damage. Slow exercise of short duration may not cause enough muscle fatigue to require recovery.
