Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes . The anaerobic glycolysis (lactic acid) system is dominant from about 10--30 seconds during a maximal effort . It replenishes very quickly over this period and produces 2 ATP molecules per glucose molecule or about 5% of glucose's energy potential (38 ATP molecules). The speed at which ATP is produced is about 100 times that of oxidative phosphorylation . </P>

The anaerobic glycolytic system would be the primary source of atp for what type of events
