what acid is responsible for muscle soreness
Delayed Onset Muscle Soreness (DOMS). Lactic acid is responsible for the burning muscles during and after exercise and this is why many suspect it to be responsible for soreness 24-36 hours after intense exercise.However, lactic acid is completely flushed out of muscles within 30-60 minutes of finishing intense exercise.owever this is a fallacy. Lactic acid is not the culprit for this muscle soreness. Lactic acid is produced during high levels of activity when the oxygen requirements of the muscles are higher than can be supplied by the blood circulation system.
