What aspect of fitness does the arm curl test primarily assess?

The arm curl test primarily assesses upper body strength. This test specifically evaluates the strength and endurance of the muscles in the arms, particularly the biceps, which are engaged during the curling movement. In the context of the Senior Fitness Test, measuring upper body strength is crucial, as it can indicate a person's ability to perform daily activities that require lifting, reaching, or pushing, which are important for maintaining independence and overall functional fitness as one ages.

The focus on upper body strength in this test also helps identify individuals who may benefit from targeted strength training interventions to improve their functionality and quality of life.
