Aerobics came about when a physician named Dr. Kenneth Cooper developed a series of exercises used to prevent coronary artery disease. Dr. Cooper authored a book in 1968 called Aerobics, that detailed his exercises which included running, swimming, bicycling and walking. Aerobic dance came about shortly after Dr. Coopers book was published, by a woman named Jackie Sorenson. She developed dance routines that were found to improve cardiovascular fitness. Sportaerobics was introduced in 1983 by Howard and Karen Schwartz. The first national aerobic championship was held in 1984 and by the year 2002, the competition included six athletes performing a 1 minute and 45 second rhythmic routine. Scores were based on artistic and technical merit. By 1996 gymnastique discipline had replaced the name sportaerobics.
