Which term refers to the ability of muscles to sustain repetitive contractions?

The term that refers to the ability of muscles to sustain repetitive contractions is muscular endurance. This concept is crucial in fitness and athletic performance, as it describes how well a muscle can continue to perform over time without fatigue. Muscular endurance is often assessed through exercises that require repeated efforts against resistance, such as performing a certain number of push-ups or sit-ups.

Achieving good muscular endurance is important for various physical activities and sports, as it allows for prolonged performance without compromising strength or efficiency. In contrast, flexibility pertains to the range of motion available at a joint, cardiorespiratory endurance relates to the efficiency of the cardiovascular and respiratory systems during sustained physical activity, and muscular strength is about the maximum force a muscle or group of muscles can exert in a single effort. Each of these terms plays a different role in overall fitness but does not specifically address the repeated contractions characteristic of muscular endurance.
