How is muscle endurance typically assessed?

Muscle endurance is most effectively assessed by determining the number of repetitions a person can perform at a moderate weight over a specific period, such as one minute. This method allows evaluators to gauge how long a muscle can sustain prolonged contractions without fatigue. Counting the number of correctly performed reps provides a practical measure of endurance, reflecting the muscle's ability to perform repetitive movements over time.

Options that focus on measuring heart rate during exercise, counting maximal load for one repetition, or conducting flexibility tests do not directly assess muscle endurance. Heart rate indicates cardiovascular response rather than muscular stamina. The maximal load test measures strength rather than endurance, as it identifies the maximum weight a person can lift in a single effort. Flexibility tests, on the other hand, evaluate range of motion rather than endurance capabilities. Thus, the identification of muscle endurance via the number of properly executed repetitions aligns the assessment with its true definition and physiological principles.
