What makes your muscles sore after a workout?
By now, you’re probably familiar with the aches and pains that come along with exercising. These sensations are present no matter how often you work out — so what causes them?
Every time you exert your muscles, you cause microscopic damage to millions of tiny proteins that make up your muscle cells. This damage leads to inflammation of the muscle — which causes the characteristic aches, pains, and stiffness experienced after a workout.
The pain after a workout usually begins the following day.
This is referred to in the medical community as delayed onset muscle soreness (DOMS).
DOMS is a healthy part of the adaptation process. It only happens when we push our muscles harder than they have before, or in a different way than we’re used to. Over time, repeating these activities will produce less DOMS as the muscles recover and become stronger and more resistant to the same level of exertion.W
