In the past, it was believed that lactic acid accumulated in the muscles of tracking athletes as a result of intense exertion. For this reason, coaches would have athletes slowly jog to move more oxygen into the muscles so lactic acid would be oxidized and there would be less soreness the next day. Based on current research, what is the most likely consequence of lactate production in the athlete’s performance? What is more likely to be the cause of muscle soreness?
