Which term describes the ability of a muscle to perform repetitive contractions over time?

The ability of a muscle to perform repetitive contractions over time is referred to as muscular endurance. This term specifically highlights how well a muscle can sustain activity over an extended period, which is crucial for activities that require sustained effort, such as running, swimming, or rowing. Muscular endurance is different from muscular strength, which focuses on the maximum force a muscle can exert in a single contraction. Flexibility pertains to the range of motion in a joint or group of joints, and cardiovascular fitness relates to the efficiency of the heart and lungs during sustained physical activity. Each of these terms addresses distinct aspects of physical fitness, but muscular endurance is specifically about the repeatability of muscular contractions over time.
