What does the Arm Curl test primarily measure?

The Arm Curl test is specifically designed to assess upper body strength, particularly in the arms. This test typically involves performing curls with a lightweight, which isolates the muscles in the upper body, particularly the biceps and triceps.

By evaluating how many repetitions a participant can perform in a set time frame, the Arm Curl test effectively provides insight into the participant's muscular endurance and strength in the upper arms, which is crucial for various daily activities such as lifting objects, reaching, and overall arm function. This measurement of upper body strength is especially important for seniors, as maintaining muscle strength is vital for mobility, independence, and the reduction of fall risk.

While flexibility, lower body strength, and aerobic endurance are important aspects of fitness, they are not the focus of the Arm Curl test, which is solely concentrated on the upper body.
