The aerobic energy system
It requires oxygen, which resynthesizes ATP to create the energy required. It is used in lower intensity exercise and provides the energy for most human activity during our lives it is also important in the recovery from exercise of all intensities.
Anaerobic exercise
It is a physical exercise intense enough to cause lactate (lactic acid). to form. It is used by athletes in non-endurance sports to promote strength, speed and power and by body builders to build muscle mass. Muscle energy systems trained using anaerobic exercise develop differently compared to aerobic exercise, leading to greater performance in short duration, high intensity activities, which last from mere seconds to up to about 2 minutes. Any activity lasting longer than about two minutes has a large aerobic metabolic component.
What is the difference between aerobic and anaerobic exercise?
In the simplest terms the difference comes down to the oxygen. With aerobic exercise oxygen is carried through your breath to the muscles giving them the energy needed to sustain the effort. Oxygen is not present with anaerobic exercise.
