ABSTRACT
Muscular endurance describes the ability to perform repeated muscle actions. 1–4 Muscular endurance is an important component of physical fitness, because most activities of daily living as well as sporting activities require multiple submaximal muscle actions. For example, household activities such as gardening, lawn mowing, shoveling snow, and vacuuming require repeated actions that often utilize the same muscles. Furthermore, although success in some sports, such as power lifting and Olympic lifting, is based on the ability to perform a single, maximal muscle action, most sports, such as rowing, swimming, cross-country skiing, bicycling, wrestling, boxing, sprinting, baseball pitching, and many others, involve repeated muscle actions. Thus, although muscular strength and muscular endurance are typically related, they involve the assessment of separate components of physical fitness.
