When does DOMS typically occur after exercise?

DOMS, or Delayed Onset Muscle Soreness, typically occurs 48-72 hours after exercise, which coincides with the body's physiological response to the stress of new or intense physical activity. During this time, the body undergoes muscle repair and recovery processes that can result in inflammation and pain at the micro-tear sites within the muscle fibers. This timing is particularly notable for individuals who engage in unfamiliar exercises or increase the intensity or duration of their workouts significantly.

This delayed onset is due to the time required for the inflammatory response and the repair mechanisms to fully develop in response to the muscle damage incurred during exercise. It is important for training and recovery protocols, as this understanding helps personal trainers guide clients through their workouts, manage expectations regarding recovery, and modify training regimens accordingly to minimize discomfort while maximizing progress.
