Chapter 3, Problem 2CT
Jogging is considered aerobic exercise because the cardiovascular 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 “nonaerobic” exercise. Explain these last two observations.
