aerobics (redirected from Aerobic & Group Fitness)

aerobics (ârō`biks), [Gr.,=with oxygen], system of endurance exercises that promote cardiovascular fitness by producing and sustaining an elevated heart rate for a prolonged period of time, thereby pumping an increased amount of oxygen-rich blood to the muscles being used. Such aerobic activities as running, swimming, and cycling can improve the body's use of oxygen, thereby allowing the heart to work less strenuously. Major Kenneth H. Cooper, a physician, pioneered the field with Aerobics (1968), which outlined fitness programs based on his study of 50,000 U.S. Air Force men and women. Since the 1980s, the term has indicated a specific type of physical fitness routine that involves a fast-paced series of exercises usually performed to the accompaniment of music. Variations include aerobic dance, jazz dance exercise, step aerobics, and low-impact aerobics. Aerobics has become one of the most popular forms of physical exercise in the United States, spawning growing memberships in exercise clubs and creating a large commercial market that includes celebrity exercise videotapes and aerobic gear.

aerobics

System of physical conditioning for increasing the efficiency of the body's intake of oxygen. Aerobic exercises (e.g., running, jogging, swimming, dancing) stimulate heart and lung activity. To produce a benefit, aerobic training must raise the heart rate (pulse) to the exerciser's target level for at least 20 minutes and include at least three sessions a week. The concept of aerobics was pioneered by Kenneth H. Cooper and popularized in his books Aerobics (1968) and The Aerobics Way (1977).
