Sit and Reach Test. This test measures the flexibility of the lower back and hamstring muscles. This following describes the procedures as used in the President's Challenge Fitness Awards. There are several other versions of the sit and reach test.
Because flexibility is joint specific, determining the range of motion of a few joints does not necessarily provide an indicator of flexibility in other joints. The most accurate tests of flexibility are those in which a goniometer is used to measure the actual degrees of rotation of the various joints. A goniometer is a protractor type of instrument used to measure the joint angle at both extremes in the total range of movement. The double armed goniometer has two arms that attach to two body parts, with the center (fulcrum) of the instrument over the exact center of the joint tested (ACSM 2010b).
