Muscular endurance refers to

• A. The maximum force a muscle can exert.
• B. The degree to which a joint can move.
• C. The ability of a muscle or muscle group to repeat a movement many times or to hold a particular position for an extended period of time.
• D. The amount of fat around a muscle.

Answer: (C)

Muscular endurance is the ability of a muscle or muscle group to perform repeated contractions or to sustain a contraction for an extended period. This is different from maximal force in a single effort (muscular strength), from how far a joint can move (flexibility or range of motion), and from the amount of fat around a muscle (body composition). So, activities like holding a plank, cycling for a long time, or doing many repetitions of a movement rely on muscular endurance. To build it, train with higher repetitions and shorter rests, gradually increasing the duration or the number of reps over time.
