Delayed onset muscle soreness (DOMS), also sometimes called muscle fever, is
the pain or discomfort often felt 24 to 72 hours after exercising and
subsides generally within 2 to 3 days. It is frequently said to be caused by
lactic acid buildup;[citation needed] however, since lactic acid disperses
fairly rapidly, it could not explain pain experienced days after exercise,
and some concentric-only exercises produce lactic acid, but rarely produce
DOMS.[1]

Although the precise cause is still unknown, the type of muscle contraction
seems to be a key factor in the development of DOMS. Exercises that involve
many eccentric contractions, such as downhill running, will result in the
most severe DOMS. This has been shown to be the result of more muscle cell
damage than is seen with typical concentric contractions, in which a muscle
successfully shortens during contraction against a load.[2]

Some research claims that DOMS is not caused by the pain from damaged muscle
cells, but from the reinforcement process.[3] The muscle responds to
training by reinforcing itself up to and above its previous strength by
increasing the size of muscle fibers (muscle hypertrophy). This
reinforcement process causes the cells to swell in their compartment and put
pressure on nerves and arteries producing pain.
