DOMS stands for Delayed Onset Muscle Soreness -- the muscle pain, stiffness, and tenderness that develops 24-72 hours after intense or unfamiliar exercise. Unlike acute pain felt during a workout, DOMS is a delayed inflammatory response caused by microscopic damage to muscle fibers, particularly during eccentric contractions.

DOMS

Delayed-onset muscle soreness can appear after unfamiliar or demanding exercise, often developing after the session rather than during it. Soreness is not caused by lactate remaining in muscle and does not measure training quality or tissue damage precisely.

Load and warning signs

Reduce or modify load when soreness changes movement or daily function. Light activity may feel helpful, but stretching does not meaningfully prevent DOMS and no single recovery method guarantees faster repair. Severe swelling, marked weakness, dark urine, fever or pain inconsistent with ordinary soreness needs medical assessment.
