Interval training utilizes the body's two energy-producing systems: the aerobic and the anaerobic. The aerobic system is the one that allows you to walk or run for several miles, that uses oxygen to convert carbohydrates from various sources throughout the body into energy.2008-05-23 13:18:03 GMT
The anaerobic system, on the other hand, draws energy from carbohydrates (in the form of glycogen) stored in the muscles for short bursts of activity such as sprinting, jumping or lifting heavy objects. This system does not require oxygen, nor does it provide enough energy for more than the briefest of activities. And its byproduct, lactic acid, is responsible for that achy, burning sensation in your muscles that you feel after, say, running up several flights of stairs.
