Which term describes the ability of muscles to exert force repeatedly over time?

Muscular endurance is the term that refers to the capacity of muscles to exert force repeatedly over an extended period. This is crucial for activities that require sustained efforts, such as long-distance running, cycling, or performing multiple repetitions of an exercise without fatigue. Muscular endurance allows an individual to perform a task continuously and maintain performance levels over time, making it essential for both athletes and individuals engaging in regular physical activities.

In contrast, muscular strength emphasizes the maximum amount of force that can be generated by a muscle in a single effort, which differs significantly from the concept of enduring repeated exertions. Power output relates to the ability to exert force quickly and is often measured during activities that require speed and strength, while flexibility pertains to the range of motion around a joint and does not focus on muscular exertion capacity over time.
