why do muscles start to REALLY hurt the following day

1.03K viewsBiologyOther

So been being more cautious about my health since I’m in my late twenties and decided to try to exercise some more. Starting out with 25 pushups and 10 burpees (probably not a lot but I felt winded) and after the exercise I felt fine. Then the next day it starts to hurt like something smart. Why though? Shouldn’t the muscles be rested after that point?

DOMS is the answer to your question. Delayed onset muscle soreness. Others might have mentioned the mechanisms or reasons.

Could be totally wrong but, I think it’s due to the fact that… When we work out, our muscle’s contractile units (called sarcomeres) become damaged. Damage in the body leads to inflammation. It’s likely the inflammation, or our bodies response to repairing damage, that causes this pain. The body releases a cascade of inflammatory cytokines (messengers) at the site of damage and this eventually causes a release of prostaglandins which I think are the cause of pain from inflammation.  This particular phenomenon is called DOMS (delayed onset muscle soreness).
