Which assessment test measures hamstring and lower back flexibility?

The sit and reach test is specifically designed to assess flexibility in the hamstrings and lower back. During this test, an individual sits on the floor with their legs extended straight ahead and reaches forward towards their toes, allowing for a measurement of how far they can reach. This test effectively evaluates the flexibility of the muscles and connective tissues in the lower back and hamstrings, which are essential for overall mobility and injury prevention.

Other assessment tests included in the options serve different purposes and are not focused on flexibility. For instance, a bioimpedance test assesses body composition, including fat and muscle mass. The push-up test evaluates upper body strength, particularly in the chest and arms. Densitometry tests, often used to measure bone density, do not relate to flexibility but rather to skeletal health. Thus, the sit and reach test remains the most appropriate choice for measuring hamstring and lower back flexibility.
