Temukanlah kata ganti pada artikel berikut ini dan sebutkan mengacu pada kata ganti apa? Aerobic exercise Aerobic exercise has the aim of improving the body's consumption of oxygen. The word aerobic means "with oxygen." Aerobic refers to our body's use of oxygen in its metabolic process (energy-generating process). Most aerobic exercises are done at moderate levels of intensity for longer periods, compared to other categories of exercise. An aerobic exercise session involves warming up, exercising for at least 20 minutes, and then cooling down. Aerobic exercise involves mainly the large muscle groups. A physical therapist, Col. Pauline Potts, and an exercise physiologist, Dr. Kenneth Cooper, both in the US Air Force, were the first to use the term aerobic exercise during the 1960s. Dr. Cooper wanted to find out why some very strong people were poor at long-distance running, swimming and cycling. He researched people's performance in terms of their ability to use oxygen with the use of a bicycle ergometer. In 1968, Dr. Cooper published his book Aerobics. The book included scientific programs using aerobic exercises, such as swimming, running, cycling and walking. The book became a bestseller. All present aerobic programs use Cooper's data as a baseline. Aerobic exercise is generally performed at a moderate level of intensity over a long period. Running for 20 minutes is an aerobic exercise, while sprinting 200 meters is not. Playing badminton for 30 minutes is an aerobic activity if the movements of the players are fairly continuous. Golf, on the other hand, is not seen as aerobic because the heart rate has not been raised at a sustained level for long enough.
