Aerobic is defined as “with oxygen” and delineates exercises and activities that use oxygen in the muscles’ energy-generating process. In a nutshell, aerobic exercise includes any type of activity performed at moderate to high intensity for extended periods of time, in which an increased heart rate is maintained. For dancers, performing full length pieces, where the heart rate is elevated for longer than two minutes at a time is considered aerobic exercise. In contrast, anaerobic is defined as “without oxygen” and delineates intense exercises that require the body to use immediate energy sources directly from the muscle as fuel. These exercises can be thought of as short (two minutes or less) bursts of energy. Dance technique classes fall into the anaerobic exercise category as combinations are usually designed to be two minutes or less in duration and then a break is taken between performing the right and left side or as each group travels across the floor. Furthermore, many class combinations rely on isometric, or static hold, exercises which fall into the anaerobic category. Because of this dichotomy in training, dancers often develop a high training affinity for power or anaerobic activity, yet burn out during performances due to an underdeveloped physiologic training of aerobic activity.
