Technical Field

[0001] The utility model relates to the technical field of physical fitness testing tools, in particular to a physical fitness testing instrument for sitting forward bending. Background Art

[0002] Sit and reach test refers to evaluating the stretchability and elasticity of the joints, ligaments and muscles of the trunk, waist, hips and other parts by testing the range of motion that these joints can reach in a static state. The sit and reach test requires the cooperation of a physical fitness tester. However, when the existing physical fitness tester is used for testing, the referee usually observes the position of the test seat on the ruler with the naked eye and reads the value on the ruler to determine whether the tester is qualified. This is not only inefficient, but also consumes a lot of physical strength and endurance for the referee. It is not suitable for sit and reach physical fitness tests for a large number of people. For this reason, the utility model improves a physical fitness testing device that can quickly and conveniently allow the referee to know whether the tester is qualified. Utility Model Content
