Delayed onset muscle soreness (DOMS)

After a hard workout, most people begin to experience soreness in the body parts trained within 24-48 hours, lasting for as long a week after the soreness sets in. This type of pain is called “Delayed onset muscle soreness” or DOMS.

Scientists aren’t 100% sure of all the causes of DOMS, but they have a pretty good idea. The burn you feel during the performance of an exercise is caused by the buildup of lactic acid, a by-product of exercise metabolism. It was once thought that the next day soreness was a result of this lactic acid staying in the muscle. Today, most exercise physiologists agree that the primary cause of DOMS is the tiny tears that occur in the muscle that as a result of high intensity exercise – especially resistance training.

When you work out, you literally “tear down” muscle tissue (these are microscopic tears – not like a “torn” muscle ) During the days after the workout, the muscle begins to rebuild itself, provided it is allowed enough time to recover and sufficient nutrients are provided. This rebuilding process creates a “new” muscle that is bigger and stronger than before. (think “scar tissue”) This is how the process of muscle growth takes place.
DID YOU KNOW THAT???
Hope this helps!
