For senior populations, what does the back scratch fitness assessment measure?

The back scratch fitness assessment is specifically designed to measure upper body flexibility, particularly in the shoulder and chest regions. This test assesses an individual's ability to reach behind their back to touch or grasp their fingers. For senior populations, maintaining flexibility is crucial as it directly impacts daily functional movements, such as reaching and lifting. Flexibility in the upper body can help improve overall mobility, reduce the risk of injury, and enhance performance in everyday activities.

The other options focus on different aspects of physical fitness that are not the target of the back scratch test. Lower body strength assesses leg strength, cardiovascular endurance evaluates heart and lung fitness, and balance stability pertains to an individual's ability to maintain equilibrium. While all these components are important for overall health, the back scratch is specifically about upper body flexibility.
