The ability to use skeletal muscles for an extended period of time is referred to as?

The correct answer is muscular endurance, which describes the capacity of skeletal muscles to sustain repeated contractions over an extended period of time without becoming fatigued. This physical fitness component is essential for activities that require continuous effort, such as running, swimming, or cycling.

Muscular endurance is different from muscular strength, which focuses on the maximum amount of weight a muscle group can lift in a single effort. Power is associated with the ability to exert maximum force in a short burst, while speed pertains to how quickly an individual can move or perform a task. Each of these components contributes to overall fitness but targets unique aspects of physical performance.
