Sit-and-reach tester and testing method thereof

Abstract

The invention belongs to a sit-and-reach tester and a testing method thereof. The sit-and-reach tester comprises a testing bottom plate, a cushion device and a testing device, wherein a square grooveis formed in the left end of the testing bottom plate, trapezoidal clamping teeth are evenly arranged on the front and rear inner walls of the square groove in the testing bottom plate, a square holeis formed in the right side wall of the square groove of the testing bottom plate, testing sliding grooves are symmetrically formed in the left end of the testing bottom plate, a cushion sliding groove is formed in the middle of the right end of the testing bottom plate, the cushion device is installed at the top of the right end of the testing bottom plate, and the testing device is installed onthe testing bottom plate. By means of the sit-and-reach tester and the testing method thereof, the problems that when existing sit-and-reach testing is carried out, during sit-and-reach testing, the body of a tested person can be skewed, the knees of the sit-and-reach tested person cannot be pressed, the legs of the tested person can move during testing, and the sit-and-reach testing result is inaccurate are solved, and the function of carrying out accurate sit-and-reach testing on tested persons of different statures can be achieved.

Description

technical field [0001] The invention relates to the field of physical education teaching equipment, in particular to a seated body flexion tester and a test method thereof. Background technique [0002] Sitting and forward bending is a physical fitness test item for primary, middle and primary schools. Its purpose is to measure the possible range of motion of the trunk, waist, hip and other joints in a static state, mainly reflecting the extensibility of the joints, ligaments and muscles in these parts and the level of development of elasticity and body flexibility. [0003] Existing people sit on the test mat when the tester performs the body forward bending test, and a stopper is set at the position of the tester's feet, and the tester's body forward bending test result is measured by manually holding a ruler. Accurate and poor tester comfort. [0004] For the body flexion testing device, existing patents have also proposed some solutions. The Chinese utility model paten...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a seated body flexion tester and its testing method, which can solve the problem that the tester's body will be skewed and bent forward during the body flexion test existing in the existing body flexion test. The tester's knee cannot be pressed, the tester's legs will move during the test, and the results of the body forward test are not accurate. The tester's body will not be skewed during the forward bend test, the knee of the forward bend tester can be pressed, the tester's legs will not move during the test, and the results of the forward bend test are accurate, etc.
