Question: 1 / 400

Muscular Endurance is defined as:

The ability to exert a maximal force in a single effort

The ability to exert a submaximal force repeatedly over time

Muscular endurance is defined as the ability to exert a submaximal force repeatedly over time. This means that it focuses on how long muscles can sustain a contraction or perform a specific task before fatigue sets in. For example, activities such as cycling, running, or performing multiple repetitions of a lower weight resistance exercise directly assess muscular endurance.

The emphasis on "submaximal force" highlights that muscular endurance does not deal with maximal efforts, as in heavy lifting, but rather with maintaining performance over longer durations with less weight. This characteristic is distinct from other physical capacities, such as maximal strength, which involves lifting heavy weights in one effort, or the ability to continue exercising without reaching failure, which might not accurately reflect endurance itself without a focus on the repetition of submaximal efforts.
