What is muscular endurance?

Muscular endurance refers to the ability of muscles to sustain repeated contractions or exert force over an extended period without fatigue. This means that a person with good muscular endurance can perform an activity, such as cycling, running, or weightlifting, for a longer duration without becoming overly fatigued. This characteristic is essential for sports and activities that require sustained physical effort, such as long-distance running or continuous swimming, where maintaining performance over time is crucial.

Understanding muscular endurance is important for designing training programs that enhance an athlete's ability to perform sustained activities effectively and efficiently. The other options describe different aspects of muscular fitness, such as the ability to exert force in short bursts, peak power output, or flexibility, but they do not accurately define muscular endurance.
