What does the chair sit-and-reach test primarily assess?

The chair sit-and-reach test primarily assesses flexibility in the lower back and hamstrings. This test requires an individual to sit on the edge of a chair and reach forward toward their toes while keeping their legs straight. The distance reached is measured, providing an indication of both lower back and hamstring flexibility. Flexibility is an essential component of physical fitness, particularly for seniors, as it can help improve mobility, reduce the risk of injuries, and enhance overall quality of life.

While flexibility is the main focus of this test, other aspects like upper body strength, cardiovascular endurance, and balance are assessed through different tests and not through the chair sit-and-reach specifically. This reinforces the importance of understanding each fitness component separately for a comprehensive approach to fitness assessment.
