Muscular endurance refers to a sustained given level of muscle force. It is important for standing or sitting for long periods. In endurance sports, it allows athletes to exercise at high intensities for long durations.
Muscular endurance depends on a combination of muscle strength and cellular endurance capacity.
In sports that require short bursts of explosiveness such as combat sports, the athelete must balance the ability to produce force rapidly with the ability to maintain the long-term energy demands of the contest.
Muscle endurance is best developed by many repetitions of an exercise, and practicing sports and activities that require considerable muscle endurance.
