Jump Box Combination Training For Boys Triple Jump An Applied Study On The Influence Of Athletes' Specific Jumping Ability

Triple jump is a track and field event with complicated skills and high requirements for athletes' physical quality.Among the various means of practice in this project,the single exercise specifically aimed at the development of athletes' speed,strength and technology is difficult to play a direct role in promoting the complete technical performance without organic integration or transition.The special jumping exercises can improve the special strength of the lower limbs,improve the technical movements,and finally improve the special jumping ability of the athletes.Special jumping ability plays a positive role in improving athletes' special performance.Developing athletes' special jumping ability is the core and foundation of improving athletes' performance.In order to improve the specific jumping ability of the triple jump athletes,it is necessary to select those jump exercises similar to the triple jump in external technical form and internal force structure.On this basis,this paper designed the vaulting box combination training,athletes through the run-up of hop,step and jump the practice combined with a combination of vaulting box,using the vaulting box and the height difference between the ground and the distance between the two vaulting box control,by practicing this special high degree of mineralization and placement is not moving in the same horizontal plane one leg to wait long practice,to develop special athletes jumping ability,so as to achieve the aim of improve the athlete special result.This study used the literature material,expert consultation,mathematical statistics,experiment.And ten young male triple jump athletes from the high-level reserve talent base of youth track and field of Wuhan university of physical education were trained for nearly four months by combination of jump boxes,aiming to improve the athletes' special jumping ability.And eventually special-item grades have been improved.After discussion and analysis with the data of the experiment,the following conclusions are drawn:(1)The special jumping ability is closely related to the triple jump performance.(2)The combination training designed in this study can develop the special jumping ability of juvenile triple jump athletes.(3)The combination training means designed in this study can develop the reasonableness of knee joint cushioning amplitude and knee and ankle joint cushioning kicking and stretching speed of triple jump athletes in the landing stage of single foot jump.It has a positive effect on improving the leg swing before folding and the knee and ankle pressing down in the landing stage.It can improve the athletes' ability to grasp the reasonable landing time.(4)The combined training method designed in this study can improve the triple jump performance of athletes in the whole run-up.
