Key concepts
3 concepts
- 1
Muscle soreness felt during exercise is primarily caused by a sustained isometric contraction that reduces blood flow and leads to acidosis.
- 2
Muscle cramps are thought to be caused by electrolyte imbalances or altered neuromuscular control, and can be relieved by passive stretching.
- 3
Delayed Onset Muscle Soreness (DOMS) is caused by eccentric contractions leading to muscle damage, and is NOT caused by lactic acid.
