What causes muscle soreness the day or two following a weight training workout?
A The muscle pain you feel a day or two after a heavy weight training workout is caused by injury to the muscle fibers and surrounding connective tissue. Contrary to popular belief, de-layed-onset muscle soreness is not caused by lactic acid buildup.
Scientists believe that injury to muscle fibers causes inflammation, which in turn causes the release of chemicals that break down part of the muscle tissue and cause pain. After a bout of intense exercise that causes muscle injury and delayed-onset muscle soreness, the muscles produce protective proteins that prevent soreness during future workouts. If you don’t work out regularly, you lose these protective proteins and become susceptible to soreness again.
