technical field

The invention belongs to a sports measurement training device, in particular to a measurement training device and a measurement method for human flexibility.

Background technique

The commonly used way to measure the range of motion of joints is sitting forward flexion. The level of development of elasticity and flexibility of the body. The usual operation method is as follows: the tester sits on the mat, straightens his legs, closes his heels, and separates his toes naturally, then his palms face down, his arms close together, and his upper body bends forward, and his two fingers move forward at a constant speed until they cannot. Until the movement, continue to do it after restoring the posture. By measuring the final movement position, the physical fitness of the tester is characterized.

A common sitting body forward bending device, as shown in the Chinese Patent Application No. 201720136824.0, includes a sitting body forward bending base; the sitting body forward bending base includes a horizontal seat plate, an arc-shaped bottom plate and a support rod; the sitting body forward bending baffle; the seat body forward bending baffle is fixed on the end of one end of the horizontal seat plate; the seat body forward bending push plate; the seat body forward bending push plate is slidably arranged on the seat body forward bending baffle. The sliding distance of the push plate of the human body represents its physical quality. The longer the distance, the greater the degree of depression of the upper body of the human body, and the better the flexibility, and vice versa. This measurement method measures a single item, which is only the degree of depression of the upper body of the human body, which is far from representing the flexibility of the human body in many aspects, and it is difficult to measure accurately for special people (the upper body is particularly long and the lower body is average). its flexibility.

The Chinese Patent Publication No. CN106880358A discloses a sitting body flexion tester, which includes a top plate, a left plate, a right plate, a bottom plate and a scale, the top plate is horizontally arranged, and the left and right plates are arranged horizontally. Vertically arranged on both sides of the top plate, the bottoms of the left and right plates are provided with pulleys; the scale is arranged on the upper surface of the bottom plate and can be on the bottom plate along the length direction.
