What does a high level of muscular endurance indicate?

A high level of muscular endurance indicates the ability to maintain muscle contractions over time. This means that a person with good muscular endurance can perform repetitive movements or exert force for an extended period without fatigue. Examples include activities like long-distance running, cycling, or performing multiple repetitions in weight training. Muscular endurance is essential for sports and activities that require prolonged physical exertion.

In contrast, options that refer to lifting heavy weights once would indicate strength, not endurance. Flexibility pertains to the range of motion of muscles and joints, which is different from endurance. Likewise, a person's body fat percentage relates to body composition rather than the ability to sustain muscle contractions. Thus, the ability to maintain muscle contractions is the defining characteristic of high muscular endurance.
