Which assessment strategy matches a component of health-related fitness for measuring abdominal strength in adolescents?

The assessment strategy that effectively measures abdominal strength in adolescents involves counting the number of curl-ups completed in a specified time. This exercise specifically targets the muscles of the abdominal region, making it a direct indicator of abdominal strength. Unlike other options, which assess different components of fitness—such as push-ups for upper body strength, plank holds for core stability, and running distance for cardiovascular endurance—curl-ups focus solely on the strength and endurance of the abdominal muscles. Therefore, using curl-ups as a measurement is both relevant and standardized in fitness assessments aimed at evaluating an individual’s abdominal strength.
