Don't know if there is really an answer to this question, or if it is just a matter of getting "old". I've noticed that the past few years that after a match, I have general muscle soreness for a day or two after a match. The rest of the day after a match is pretty useless. Is this just a matter of getting on in age (I just turned 53), or is it a matter of lactic acid buildup in the muscles? If it is lactic acid, how does one minimize it, or its effects? Thank you.
