Question

Quizplus · Accepted Answer

Delayed onset muscle soreness (DOMS) is typically the result of microscopic tears in muscle fibers. As the muscle fibers repair and rebuild, calcium is released from the sarcoplasmic reticulum, resulting in inflammation and soreness. This process typically occurs 24-48 hours after exercise, and is not related to lactic acid buildup or glycogen depletion. Muscle cramps may occur during exercise or as a result of dehydration or electrolyte imbalances, but are not typically associated with DOMS.
