Chemical energy. The currency of metabolism is adenosine triphosphate (ATP) which is responsible for all human muscular mechanical activity. However, the type of energy is very simply "chemical".
Anaerobic exercise utilizes oxygen for energy production
protein
it can produce energy in the presence and absence of oxygen unlike aerobic exercise which can only produce energy in the presence of oxygen
Anaerobic
In Anaerobic exercise
anaerobic respiration causes a build up of lactic acid in your muscles which causes cramp.

anaerobic exercise is an exercise whereby an an individual is active in the absence of oxygen.
Anaerobic exercise uses about 10 times more energy than aerobic exercise, and you have more "fuel" available for aerobic exercise. Anaerobic exercise also produces lactic acid, which is what causes your muscles to burn.
energy and lactic acid.
In aerobic exercise, the energy used comes primarily from aerobic metabolic processes which use oxygen to process the "fuel" being metabolized. This is in contrast to anaerobic exercise where the energy used comes primarily from metabolic processes that do not require separate oxygen.
