Which of the following is a test used to assess muscle endurance?

The push-up test is a widely recognized method for assessing muscle endurance, particularly in the upper body. This exercise requires participants to perform as many repetitions as possible within a set time frame or until they can no longer maintain proper form. The focus of the push-up test is to evaluate how well a person's muscles can sustain repeated contractions over time, which is the essence of muscular endurance.

Muscle endurance is vital for various physical activities, and tests like push-ups can provide useful insights into an individual’s fitness level. This is especially important for athletes and individuals looking to improve their overall strength and stamina, as it helps identify areas for targeted training.

In contrast, other tests mentioned have different purposes. Flexibility tests generally assess the range of motion in joints rather than muscular endurance. Body composition analysis determines the proportion of fat and lean mass in the body, which does not directly reflect endurance capabilities. Similarly, the VO2 Max measurement evaluates cardiovascular fitness and aerobic capacity rather than focusing on muscle endurance specifically.
