What does the Back Scratch test measure?

The Back Scratch test specifically measures upper body flexibility, particularly the flexibility of the shoulder joints and muscles. This test assesses how well an individual can reach over their shoulder and under their arm to touch their fingers, which requires mobility in the shoulder girdle and adequate arm flexibility. It is especially relevant for seniors, as maintaining flexibility in these areas can help with daily activities and overall quality of life.

The other options represent different aspects of physical fitness unrelated to the Back Scratch test. Lower body flexibility would involve tests targeting the hips and legs, cardiovascular endurance is evaluated through activities that assess heart and lung function, and strength of grip would be assessed through various hand grip tests. Each of these areas focuses on different elements of physical fitness and does not reflect the goals or outcomes of the Back Scratch test.
