How is muscular endurance defined?

Muscular endurance is defined as the ability to perform repetitive muscular contractions against resistance over an extended period. This involves sustaining activity without significant fatigue, allowing an individual to engage in prolonged physical activities that require strength, such as running, cycling, or weight training with lighter weights over multiple repetitions. The focus on repetitive muscular contractions is key, distinguishing muscular endurance from other concepts like maximum strength or power, which focus on single efforts or shorter bursts of activity.

Understanding muscular endurance is crucial for designing training programs tailored to specific athletic goals, where activities demand sustained effort and low to moderate intensity over time.
