What does delayed onset muscle soreness typically involve?

Delayed onset muscle soreness (DOMS) specifically refers to the muscle pain and stiffness that typically arises a day or two following unfamiliar or intense exercise. The characteristic of this soreness is that it often becomes more pronounced 24 to 48 hours after the activity, which aligns with the physiological response of muscle repair and adaptation following exercise-induced muscle damage.

This delayed response is an important aspect of DOMS, as it is not immediate but rather develops over time. The discomfort is associated with inflammation and the process of muscle recovery, which includes the reparation of microscopic tears in muscle fibers. This understanding highlights why individuals commonly report heightened soreness two days post-exercise, making the understanding of DOMS critical for athletes in managing their training and recovery protocols effectively.
