Description
Technical Field
The utility model relates to a sport equipment field especially relates to a testing arrangement that seat body was anteflexed.
Background
Seat forward flexion is a test item used to reflect human flexibility. Flexibility refers to the ability of the body to stretch the joints, muscles, tendons, and ligaments when performing an action. The quality of the pliability depends on the anatomy of the joint and the size of the soft tissue surrounding the joint, as well as the extensibility of ligaments, tendons, muscles and skin. In order to encourage and promote students to actively take part in physical exercise and enhance the physique of the students, the 'student health standard' is tried in China in 2002. The sitting body forward bending item belongs to one of the test contents specified by the standard. According to the research results of the national student physical health and health, the ministry of education and the national general sports bureau perfect and modify the 'student physical health standard'. The anteflexion of the sitting position is one of the selection items in the examination in Chinese sports.
The sitting body forward bending is used for testing the possible activity amplitude of joints of the trunk, the waist, the hip and the like of the student in a static state, and mainly reflects the extensibility and elasticity of the joints, ligaments and muscles of the parts and the development level of the body flexibility of the student.
The commonly used test device for forward flexion of the sitting body is shown in fig. 1. The foot supporting plate 11-1 is vertically and fixedly connected with the horizontal supporting plate 11-5; a supporting reinforcing plate 11-6 is fixed between the foot supporting plate 11-1 and the horizontal supporting plate 11-5; the front end surface of the foot supporting plate 11-1 is a test reference surface 3; a scale guide rail 11-4 is fixed at the middle upper part of the foot supporting plate 11-1; the scale guide rail 11-4 is vertical to the test datum plane 3; the upper end surface of the scale guide rail 11-4 is provided with a body scale mark 11-2 of centimeter and millimeter; the 0 scale mark of the body scale mark 11-2 on the scale guide rail 11-4 is flush with the test reference surface 3; the body sliding vernier 11-3 is sleeved outside the scale guide rail 11-4 and can slide longitudinally along the scale guide rail 11-4.
The commonly used method for testing the forward flexion of the sitting body is shown in fig. 2. The tested 15 people sit, and the sole surface is tightly attached to the testing reference surface 3 of the commonly used sitting body forward bending testing device body 11. Then the trunk bends towards the direction of the legs, the arms extend towards the direction of the tiptoes, and the arm fingertips 10 push the body sliding cursor 11-3 forwards until the forward pushing cannot be continued.
In fig. 2, the distance from the arm fingertip 10 to the shoulder joint 8 is arm length 9, the distance from the shoulder joint 8 to the hip joint 5 is trunk length 6, the included angle between the connecting line 7 from the shoulder joint 8 to the hip joint 5 and the horizontal reference line is bending included angle α, the distance from the hip joint 5 to the test datum plane 3 is leg length 4, and the test result of the forward bending of the commonly used seat at present is the distance from the arm fingertip 10 to the test datum plane 3, namely, the bending state of the finger heel distance 1 in the present invention.
As can be seen from fig. 2, the bending state refers to the following distance 1= arm length 9+ trunk length 6 · cos α -leg length 4, so the test result of the currently commonly used method for testing the forward flexion of the sitting position refers to the following distance 1 having a correlation with the arm length 9, the trunk length 6, the leg length 4 and the bending angle α, wherein only the bending angle α can reflect the flexibility of the human body more truly, and the arm length 9, the trunk length 6 and the leg length 4 have no direct correlation with the flexibility of the human body.
Therefore, the current testing method has the following disadvantages:
under the condition that the trunk length 6 and the bending included angle α are the same, the test result of the student with the arm length of 9 and the leg length of 4 is obviously better than that of the student with the arm length of 9 and the leg length of 4.
The above disadvantages indicate that the existing testing method for forward bending of sitting body can cause unfairness. Because objective factors such as leg length and arm length are influenced by genetic factors and development time, the objective factors cannot be changed in a short period by painstaking exercise. The students with long legs and short hands have inherent disadvantages in the achievement of forward bending of the seat body commonly used at present, and the final achievement can not reach the standard even though the students are subjected to hard exercise. The students with long hands and short legs have congenital advantages on the performance of forward bending of the seat body commonly used at present, and can easily obtain good performance.
