FITNESS 101: Aerobic vs. Anaerobic Exercise
Which is best for you? The answer is not as complicated as it seems.
ing up adenosine triphosphate and creatine phosphate from your body as quick-and-dirty forms of fuel. The drawback, however, is that your body cannot store ATP and it quickly runs out, lasting on average 10 to 15 seconds. After that it has to switch to another energy system.
The good news is that if you have plenty of stored glycogen, you will regenerate ATP pretty quickly and will be able to perform again explosively and powerfully with a little break in between. This is why you can do repeated sprints or several sets of box jumps for more than one round.
Aerobic training, such as distance cycling, running and hiking, uses oxygen and glycogen to power your activity.
