Jogging is considered aerobic exercise because the cardio-vascular system (heart and blood vessels) can adjust to supply the oxygen needs of working cells. In contrast, sprinting the 100-meter dash might be called anaerobic (lacking oxygen) exercise, and golf non aerobic exercise. Explain these last
