There are two primary energy systems in the body, one is dependent on oxygen (aerobic), the other is not (anaerobic), both burn carbohydrate – glucose in the blood and glycogen in the muscle. Intense exercise requires more oxygen than is available to the aerobic system; this is when the anaerobic system kicks in and does the trick oxygen-free. The end product of anaerobic exercise is lactic acid which, through a concatenation of chemical reactions, is recycled again and again into energy.
