What type of fitness does the sit and reach test primarily assess?

The sit and reach test primarily assesses flexibility, which is the ability of a joint or group of joints to move through a full range of motion. This test specifically measures the flexibility of the lower back and hamstring muscles. By having an individual sit on the floor with their legs extended and then reaching forward towards their toes, the test evaluates how far they can stretch without bending their knees. A greater reach indicates better flexibility, particularly in the posterior chain of muscles, which includes the hamstrings, glutes, and lower back.

Flexibility is an important component of physical fitness, as it contributes to overall body movement, sports performance, and the prevention of injuries. The sit and reach test is widely recognized for its simplicity and reliability in assessing this specific aspect of fitness.
