10. ANAEROBIC FITNESS is the ability to work at a high intensity for a short period of time. Anaerobic exercise can only last for about 40 secs, about the time it takes a world class 400m runner to complete the race. The repayment comes in the form of gasping breaths at the end of activity. This is to enable as much oxygen as possible to get back into the respiratory system and to eliminate as much of the waste product as possible. This is known as OXYGEN DEBT.
