Acute muscle soreness (AMS) is the pain felt in muscles during and immediately, up to 24 hours, after strenuous physical exercise. The pain appears within a minute of contracting the muscle and it will disappear within two or three minutes or up to several hours after relaxing it.[1]
There are two causes of acute muscle soreness:[1]
- Accumulation of chemical end products of exercise in muscle cells such as lactic acid and H+
- Muscle fatigue (the muscle tires and cannot contract anymore)
