ice or cold baths day before game

Lactic acid is there because of exertion when there is not enough oxygen and glucose readily available for aerobic respiration. It is produced under anaerobic conditions to give cells another source of energy. It is not known for sure if it is the cause of pain or not after the exertion, or if it is just during the workout. Ice is there to minimize inflammation and swelling--it does not do anything for lactate buildup. Ice is always a safe thing when someone has the potential for developing any sort of inflammation. If it works use it, but don't buy in to that "pulling lactic acid out like a sponge" bs. Ice is for inflammation only as is ibuprophen.
