What physical quality does the chair sit and reach test primarily assess?

The chair sit and reach test primarily assesses lower body flexibility. This test specifically evaluates the flexibility of the hamstrings and lower back by measuring how far a person can reach while sitting on a chair with their legs extended. Flexibility is crucial for maintaining mobility and preventing injuries, especially as individuals age. The test is straightforward, requiring participants to sit at the edge of a chair and reach toward their toes, making it an accessible measure of flexibility for seniors. By focusing on this area, the test helps highlight the importance of flexibility in overall physical function and quality of life in older adults.
