What does DOMS stand for?

Delayed Onset Muscle Soreness, commonly referred to as DOMS, is a condition that occurs after intense physical activity, especially after unfamiliar or intense exercise. This type of soreness typically sets in 24 to 72 hours after the activity, which is what 'delayed onset' signifies. The soreness is caused by microscopic tears in muscle fibers that occur during exercise, leading to an inflammatory response in the body.

Understanding DOMS is essential for fitness trainers as it helps them educate clients about post-exercise recovery and the normal physiological responses to exercise. Proper management of DOMS includes strategies such as active recovery, hydration, and stretching, which can aid in alleviating discomfort and helping the muscles recover.
