ABSTRACT
The development of aerobic and anaerobic conditioning through physical training is significant to overall cardiovascular fitness and function. Metabolically, aerobic endurance provided by the oxidative system for long-distance performance is gained through work in the presence of oxygen, while anaerobic conditioning, made available through the use of the phosphagen or adenosine triphosphate-creatine phosphate (ATP-CP) and fast glycolytic or lactic acid systems for immediate and intensive physical activity, is attained through work without the presence of oxygen. The energy responses produced by these systems contribute to the resulting physiological work capacity of the body in regard to physical performance.
