Embodiment 1

[0049] There are infinitely many joint characteristic curves in the snatch process of athletes in the continuous space. Therefore, it is difficult to solve the snatch action by genetic algorithm, and the optimization effect is not ideal. In order to improve this problem, the inventor found through various researches. The characteristics of the whole set of snatch movements can be divided into five processes: lifting the bell, pulling the knees, exerting force, jumping back and supporting, and jerking up. Among them, the point of exerting force is the key to the success of the entire weightlifting movement. Athletes complete the specified snatch action through the transformation of external force and internal force when doing bell lifting. Considering this issue from another perspective, weightlifting is a continuous process, and the energy of human muscles is limited. How to make full use of it? Limited energy is an important indicator to examine the pros and cons of technical ...

Embodiment 2

[0090] There are infinitely many joint characteristic curves in the snatch process of athletes in the continuous space. Therefore, it is difficult to solve the snatch action by genetic algorithm, and the optimization effect is not ideal. In order to improve this problem, as follows: image 3 As shown, the embodiment of the present invention provides a snatch action optimization device, comprising:

[0091] The model building unit is used to establish a biomechanical model in advance. There are multiple biomechanical models corresponding to multiple snatch actions in the snatch process. The biomechanical model includes multiple links and links connected to the ends of the links. multiple joints of the shank, thigh, torso, upper arm, and forearm;

[0092] Wherein, a plurality of biomechanical models established by the model building unit are preferably planar models, corresponding to a plurality of snatch actions in the snatch process, such as figure 2 As shown, the embodiment...

Abstract

The embodiment of the invention provides a snatch action optimization method and device. The snatch action optimization method and device solve the problems that when snatch actions are optimized in the prior art, solving difficulty is high, and the optimization effect is not ideal. The method comprises the steps that coordinate systems are established at all joints of all biomechanical models, so movement loci of all the joints and coordinate system vectors qi of all the joints in all the biomechanical models are obtained; joint speed vectors and joint angular speed vectors in all the biomechanical models are figured out; torques Qia of all the joints in all the biomechanical models are obtained according to the joint speed vectors figured out; according to the torques Qia of all the joints and the joint angle speed vectors, the sum of the torques of all the joints and the sum of works of all the joints in all the biomechanical models are figured out; the optimal snatch action of which the sum of the torques of all the joints and the sum of the works of all the joints in all the biomechanical models are the minimum is used as the optimum action. By using the method, the solving difficulty can be lowered remarkably, the optimization effect can be improved, the method is convenient to implement, and the method and device are easy to apply and popularize.

Description

technical field [0001] The present invention relates to the field of competitive sports competitions, in particular to a snatch action optimization method and device in competitive sports competitions. Background technique [0002] In competitive sports competitions, the snatch is a highly technical and highly ornamental heavy competitive event. It is an action that quickly and continuously lifts the barbell from the weightlifting platform to the straightening of the two arms above the head: two feet left and right Stand separately, hold the bar with both hands and lift it up. When the barbell reaches the height of the chest, the body squats down, so that the body is under the barbell, the arms are straight to support the barbell, and the legs are retracted. [0003] Different from ordinary competition events and general voluntary movements of the human body, the snatch must not only meet certain biomechanical constraints, but also comply with the corresponding technical mov...
