Embodiment 1

[0086] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0087] An artificial intelligence diagnosis method for standing long jump, comprising:

[0088] 1. Optimization of take-off technology:

[0089] The plantar pressure test system is used to collect the data of the whole process of the standard long jump and triple jump athletes standing long jump take-off, and establish the forward dynamic equation; set the objective function, according to the pressure distribution between the foot and the support surface during the standing long jump, Optimize the design of the standing long jump technology to give full play to the ergonomics of the metatarsophalangeal joints.

[0090] 1.1. Calculation of the pressure in the vertical direction during the take-off phase:

[0091]

[0092] where P ij (t) is the vertical pressure at a certain moment t, p (i,j) (t) represents the pressure value of the sensor at the position (i, j) at a certain moment, T is the ti...

Embodiment 2

[0125] Please refer to Figure 2-Figure 8 , the second embodiment of the present invention is:

[0126] This embodiment corresponds to Embodiment 1, and provides data analysis and comparison cases of standing long jump using normal postures and the optimal standing long jump technical template obtained according to Embodiment 1 to fully utilize the working posture of the metatarsophalangeal joint winch:

[0127] see figure 2 and image 3 ,in, figure 2 It is a schematic diagram of the key action points when performing a standing long jump with a normal posture, image 3 It is a schematic diagram of the key action points when performing the standing long jump using the optimal standing long jump technical template (that is, giving full play to the working posture of the metatarsophalangeal joint winch).

[0128] see Figure 4 , for the respective figure 2 posture and image 3 The figure of the support surface rebound force-time relationship in the whole process of stan...

Abstract

The present invention provides a method for obtaining the optimal standing long jump technical template, which includes collecting the kinematics and dynamics data of an athlete's standing long jump whole process; establishing a forward dynamics equation for taking off according to the data corresponding to the whole process of taking off in the data, and combining the standing The pressure distribution between the foot-support surface during the long jump is used to obtain the take-off technical equation; the objective function of the lower limbs is established according to the data corresponding to the flight time in the data, and the technical equation of the flight is obtained in combination with the relative motion law of the human body in the air; according to the athlete's ankle Establish the geometric model and finite element model of the foot bone based on the high-resolution tomographic images of the upper part, and calculate the best landing action; establish the optimal standing long jump technical template. The invention can provide a matching template for the artificial intelligence diagnosis of the standing long jump technology (joint kinematics), and provide a theoretical basis for the optimal design of sports aids.

Description

technical field [0001] The invention relates to the field of sports rehabilitation engineering, in particular to a method for obtaining an optimal standing long jump technical template. Background technique [0002] "National fitness and health first" is the national development strategy, and the "National Physical Exercise Standards" are the basic requirements of the country for students' physical health. In order to further implement this standard, the importance of "physical education" is highlighted. For example, in the senior high school entrance examination (junior high school academic level examination), the standing long jump can not only develop the explosive power of the lower limbs, but also develop the strength and coordination of the trunk and upper limbs. In 2014, the "National Physical Health Standards for Students" stipulated that the standing long jump is an annual compulsory test for junior high schools, high schools, and universities. About 10 million stu...
