title: Exercise-Induced Skeletal Muscle Damage.
abstract: In brief: Delayed-onset muscle soreness is most likely caused by structural damage in skeletal muscle after eccentric exercise, in which muscles produce force while lengthening, as in running downhill. This damage may take as long as 12 weeks to repair. Therefore, athletes should allow plenty of time for recovery after events that cause extreme muscle soreness. Because prostaglandin E2 may be important in muscle repair, prostaglandin blockers, such as aspirin, may be useless or even detrimental in the treatment of delayed-onset muscle soreness. Eccentric exercise training may help prevent soreness.
