Anaerobic Physical Activity

You're not able to do anaerobic physical activities for long periods because you have limited amounts of anaerobic fuel supplies. For this reason, you must separate bouts of intense physical activity with bouts of rest. During the rest periods, your body is regenerating the anaerobic fuel so that you may engage in another bout of intense physical activity. The sports that require anaerobic physical activity are characterized by intense bouts of activity followed by bouts of rest. For example, hockey players work in shifts of about 45 seconds and then rest while other players take the ice. Football players engage in explosive bouts of physical activity that last about 15 to 20 seconds and then rest between downs. Soccer also requires anaerobic physical activity interspersed with periods of rest. Can you think of other anaerobic physical activities that you have participated in?
