Why do you get sore after not working out for a while, but then the next time training you don’t get sore?

Question

The muscle damage is the same, so wouldn’t the DOMS be the same?

In: Biology

Answer 1

DOMS is the result of muscle fibers being strained with tiny tears. As you probably know, muscles become stronger as those tiny tears are repaired. Doing a workout of the same intensity will no longer cause DOMS after the initial soreness goes away, as it isn’t enough to cause those tiny tears anymore.
