Which test is NOT included in the methods for assessing muscular endurance?

The plank test is primarily used to assess core stability and strength rather than muscular endurance. While it does involve the muscles of the core, it focuses on maintaining a static hold rather than performing repeated movements over time, which is a key characteristic of muscular endurance assessments.

In contrast, the sit-up test and the push-up test involve performing multiple repetitions of an exercise within a specified timeframe, directly measuring the endurance of the abdominal and upper body muscles, respectively. Similarly, any upper body test that involves repeated movements would also fall under muscular endurance assessments. Therefore, the plank test stands out as it does not adhere to the same assessment principles that define muscular endurance evaluations.
