Define muscular endurance.

Define muscular endurance.

• A. The ability of a muscle to perform repeated contractions over time
• B. The maximum rate of force production
• C. The speed of muscle contraction
• D. The range of motion of a joint

Answer: (A)

Muscular endurance is the ability of a muscle to perform repeated contractions over time, resisting fatigue during sustained activity. This means you can continue an activity like push-ups, cycling, or holding a plank for longer periods without tiring rapidly. It’s not about how fast you can generate force, how quickly a muscle can shorten, or how far a joint can move. Those other qualities describe maximum force production, contraction speed, and joint range of motion, respectively.
