Eli5: Why do you feel the burn after exercise such as lifting weights or a run after two days rather than immediately afterwards?
In: Biology
I was just listening to a podcast on this, and basically, we don’t know..
The mechanism of both immediate and delayed muscle soreness aren’t really known it seems like its not actually the same as fatigue and also not necessarily related to other things like micro muscle tears or whatever. Just because your muscle is sore doesn’t mean you can’t exercise or even hit a PR..
I mean I almost think any discussion of soreness should clarify if we’re talking about soreness you experience when you’re new to exercise vs general muscle soreness because I’ve never ever in my entire life been as sore as day 2-3 of the first time I decided to go to the gym (or went back to the gym after a long absence) and we’re talking about a factor of 10x so no, if you don’t normally exercise it doesn’t always feel like this in fact it almost never feels anywhere near this bad
