Endurance

Endurance

• Endurance or aerobic exercise consists of performing low- to medium-intensity exercise for very long periods of time. E.g., jogging or running several miles to hundreds of miles; cycling dozens of miles to thousands of miles; swimming hundreds of yards to dozens of miles.

• Physical endurance is differentiated from other forms of physical stress in that in endurance exercise fatigue of the muscles and cardiovascular system do not force the effort to end. The need for sleep, the buildup of non-recyclable waste chemicals, the depletion of convertible energy stores and other needed chemicals (e.g., water, sodium), physical injury, psychological failure, or attainment of the goal will bring the effort to an end.

• Abiltiy to maintain or go the distance: work hard for a long or extended amount of time.
