what symptoms are normal to experience after strenuous exercise
Delayed onset muscle soreness. Delayed onset muscle soreness (DOMS), also called muscle fever, is the pain and stiffness felt in muscles several hours to days after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise. It is thought to be caused by eccentric (lengthening) exercise, which causes microtrauma to the muscle fibers.
