Cardiovascular Activities
The term aerobic was made popular by Dr. Kenneth Cooper in the late 1960s. The name was derived from Greek roots -- aero, or air; and bios, or life. Since aerobic training plays a role in the prevention of cardiovascular disease, it's often referred to as cardiovascular training. In order for an activity to be aerobic it must be rhythmic in its nature, use the large muscle groups and be continuously maintained for 20 to 60 minutes. It must also challenge the heart and lungs, but without overdoing it. Walking, hiking, swimming, running, cycling, rope skipping, rowing, stair climbing and group fitness classes such as low impact aerobics and indoor cycling are all aerobic.
