Nature & DOMS (Delayed Onset Muscle Soreness)

Soldier, Loaded Carry, Loaded March“Pain exists to get an animal to change its behaviour.

This functional account of pain may explain some ongoing mysteries, such as the cause of the muscle soreness that follows a day of intense exercise, which has eluded physiological explanation.

The popular idea that it is due to the build-up of lactic acid has been discounted, as have other proposed theories.

Body builders have found that the optimal way to build muscle is to take a rest day after a strenuous workout.

Perhaps nature has converged on the same idea, and muscle soreness is simply a signal to rest, to enable optimal muscle building.”
