Sit-and-reach exercise equipment for primary and secondary school students

Abstract

The invention discloses a sit-and-reach exercise apparatus for primary and secondary school students and relates to the technical field of sit-and-reach exercise apparatuses. The sit-and-reach exercise apparatus comprises a sitting plate, a pedal plate and a measuring guide rail, wherein the pedal plate and the measuring guide rail are arranged at one end of the sitting plate, and an adjusting part is slidably arranged on the measuring guide rail; the sitting plate is rotatably connected with a pressure applying part, the pressure applying part is connected with the adjusting part through a guide traction assembly, and the adjusting part cooperates with the guide traction assembly to synchronously drive the pressure applying part to rotate so as to apply pressure to a waist, the back and shoulders of a practicer when moving on the measuring guide rail. a pressure applying part is in rotation connection with the sitting plate, the pressure applying part is connected with the adjusting part through the guide traction assembly, and when the practicer pushes the adjusting part to move on the measuring guide rail during sitting body forward bending practice, the adjusting part is matched with the guide traction assembly to synchronously drive the pressure applying part to rotate so as to apply pressure to the back of the practicer; and exerting pressure and stretching exercises on the waist, the back and the shoulders of an exerciser are facilitated.

Description

technical field [0001] The invention relates to the technical field of sitting and forward bending exercise equipment, in particular to a sitting and forward bending exercise equipment for primary and middle school students. Background technique [0002] As is well known, in order to encourage and promote students to actively participate in physical exercise and enhance students' physical fitness, the "Students' Physical Health Standards" was tried out in China in 2002. Sitting and forward bending is one of the test items stipulated in the standard. Sitting and forward bending is a basic item in the physical health test of primary and secondary schools, and it is also one of the seven selected two items in the physical education entrance examination. It is mainly used to measure the trunk and waist in a static state. The possible range of motion of joints, hips and other joints mainly reflects the extensibility and elasticity of the joints, ligaments and muscles in these par...

Problems solved by technology

[0004] The disadvantage of the prior art is that the instruments currently used as sitting and forward bending exercises and tests are all the same, and the exercises and test methods are the same as those of the subjects. Sit on the floor with straight legs and waist, place your feet on the surface of the board, keep your back against the back board, straighten your arms and fingers and drop naturally to the height of the table, keep your five fingers together, and start pushing with the middle finger In practice, the students' muscles and ligaments are not effectively stretched by using this traditional measurement method. In actual practice, one or two people are needed in order to perform effective stretching exercises on the students' muscles and ligaments. Cooperate with a practitioner to assist in pressing the practitioner's back for practice, making it impossible for a single person to practice, and it is inconvenient to use. At the same time, others assist in pressing the back for practice. Unsatisfactory effect and difficult to guarantee safety
