【摘要】：对铅球运动员投掷目标进行技术优化,可以提高铅球比赛成绩。进行投掷目标技术优化时,应以运动员上肢投掷训练为主,计算上肢专项训练对投掷目标训练的影响程度,获得运动员肩部肌肉群协同"推"铅球过程发力的协同作用效果指标,但是传统方法通过分析上肢投掷训练与铅球运动员成绩之间的关系进行技术优化,但是不能获取明确的运动员肩部肌肉群协同"推"铅球过程发力的协同作用效果指标,降低了技术优化效果。提出一种基于灰色关联分析的铅球运动员投掷目标技术优化模型。上述模型先融合于灰色关联分析理论获取铅球运动员成绩及上肢专项绝对力量、上肢专项速度力量训练两方面影响因素初值像,计算出上肢绝对力量训练与运动员成绩之间的相关性系数,得到上肢绝对力量训练各影响因素与运动员成绩的关联度,获取上肢肌肉组织与支撑系统之间的相互作用关系,计算出上肢专项速度力量训练下上肢肌肉的做功强度对运动员成绩的影响程度,给出逐渐增加上肢投掷训练负荷过程中运动员在"拨"及"推"铅球过程中肌肉群的发力力量,获得运动员肩部肌肉群协同"推"铅球过程发力的协同作用效果指标,并组建铅球运动员投掷目标技术优化模型。仿真结果表明,所提模型能够精确的对铅球运动员投掷目标进行技术优化。
[Abstract]:The technical optimization of shot-put players can improve the performance of shot-put competition. In the optimization of throwing target technique, athletes' upper limb throwing training should be the main factor, and the influence degree of upper limb special training on throwing target training should be calculated. The synergetic effect of shoulder muscle group in the process of pushing shot put was obtained, but the traditional method was optimized by analyzing the relationship between the training of upper limb throwing and the performance of shot put athletes. However, it can not obtain the specific cooperative effect index of the shoulder muscle group in the process of "pushing" shot put, which reduces the effect of technical optimization. This paper presents an optimization model of throwing target technique for shot put athletes based on grey correlation analysis. The above model is integrated into grey relational analysis theory to obtain the initial value image of the two factors influencing the performance of shot put athletes and the specific strength of the upper limb and the training of the specific speed strength of the upper limb. The correlation coefficient between upper limb absolute strength training and athletes' performance was calculated, and the correlation degree between the influence factors of upper extremity absolute strength training and athletes' performance was obtained, and the interaction between upper limb muscle tissue and support system was obtained. The influence of the working intensity of the upper limb muscle on the athletes' performance was calculated, and the strength of the muscle group in the process of "plucking" and "pushing" the shot put during the training process of the upper limb throwing was gradually increased, and the influence of the strength of the upper limb muscle on the performance of the upper limb muscle was calculated. The synergetic effect index of the shoulder muscle group in the process of "pushing" the shot put was obtained, and the optimization model of the throwing target technique of the shot put was set up. The simulation results show that the proposed model can accurately optimize the throwing target of shot put players.
