What test measures isometric endurance of the trunk musculature?

The two-minute plank test is designed specifically to assess isometric endurance of the trunk musculature. During this test, an individual maintains a plank position, engaging the core muscles without dynamic movement, which effectively evaluates the ability of the trunk muscles to sustain a contraction over time. This isometric nature of the plank allows for the measurement of endurance, distinguishing it from other tests that may assess strength or muscular endurance through repetitive movements.

The one-minute sit-up test focuses more on dynamic endurance of the abdominal muscles, while the leg-tuck test evaluates strength and endurance of the upper body and core in a different manner. The push-up test also measures muscular endurance, but it predominantly targets the chest, shoulders, and triceps rather than specifically isolating trunk musculature.
