>>128904 >Soreness happens because of lactic acid buildup and tearing of the muscle fibers. lactic acid dissipates in a manner of seconds, and only can be attributed to the "burn" you feel during an exercise. The "tearing" you're referring to should be specified as micro-tears, because there's a big difference between the two, and could cause some confusion. Anyway, it's a contributor to DOMS (delayed onset muscle soreness), but as of right now I don't think it's completely understood, there's some stuff about Concentric and Eccentric muscle contractions, but I don't recall the details.
However, it's becoming apparent that DOMS is inaccurate, and that only the first 2-3 days should be heeded, and if you're sore for 6 days or so, half that time you're already completely recovered.
