What does the curl-up assessment measure?

The curl-up assessment specifically measures abdominal muscular endurance. This exercise focuses on how well the abdominal muscles can sustain contractions over a period of time, which is essential for maintaining good posture and core stability. Abdominal endurance is critical in many physical activities and sports, as it supports movements that require strength and control of the core.

The curl-up involves repeatedly lifting the upper body off the floor while in a supine position, which directly engages the abdominal muscles. The ability to perform numerous repetitions without significant fatigue indicates a strong level of endurance in those muscles.

Other assessments mentioned, such as upper body strength, cardiovascular endurance, and overall flexibility, target different fitness components and do not accurately describe what the curl-up assessment evaluates, thereby highlighting why the correct choice focuses on abdominal muscular endurance.
