How is "muscular endurance" defined in TC 7-22.7?

Muscular endurance is defined as the ability of a muscle or group of muscles to sustain repeated contractions over time. This definition emphasizes the importance of performing physical tasks for extended periods without experiencing fatigue, which is essential in many athletic and physical activities. Muscular endurance is critical for activities that involve prolonged muscle use, such as running, cycling, or performing multiple repetitions in resistance training.

The focus is on the sustained effort of the muscles rather than on maximum strength or the ability to lift heavy weights in a single effort. This key distinction makes it clear that muscular endurance is about maintaining performance over time, rather than the intensity of a single contraction or the recovery rate of muscles. Understanding this definition helps in developing training programs that target the improvement of endurance through specific types of exercises and repetition schemes.
