Because it reflects the conditions of these vital organs, the aerobic capacity is the best index of overall physical fitness.

 Collectively, the changes induced by exercise in the various systems and organs of the body are called the training effect. Unless the exercise is of sufficient intensity and duration, it will not produce a training effect and cannot be classified as an aerobic exercise.
