What does muscular endurance refer to?

Muscular endurance specifically refers to the capacity of muscles to sustain repeated contractions or to continue exerting force over an extended period. This means that a person with high muscular endurance can perform physical activities, such as running, cycling, or lifting weights, for longer durations without experiencing fatigue. Such endurance is essential for many sports and everyday activities, as it allows individuals to maintain performance even as they tire.

In contrast, other choices address different aspects of physical fitness. The ability of muscles to exert force is more aligned with muscular strength. The distance traveled per unit of time relates to speed or velocity. Lastly, the rate at which work is done refers to power. Each of these concepts is important in the realm of sports medicine and fitness, but they do not capture the specific meaning of muscular endurance.
