Experimental Study On Infuence On The Explosive Force Of Lower Limbs Under Different Stretch Excercises

The purpose of this study is through comparing the influence of different stretching of explosive,and explore the influence of its internal mechanism,tries to find out different characteristics or requirements of sport as a better stretching mode of science,the preparation activities for the coaches and athletes in sports training or preparation work before the game to provide a positive reference.This study in the reading extensively,on the basis of related literature and expert interview,on 29 from Beijing sports university sports professional subjects without stretching and dynamic stretching,proprioception neuromuscular facilitation + dynamic tensile and proprioception neuromuscular facilitation method four warm-up mode of experimental intervention,and USES the three dimensional measurement of power stations and wireless synchronous multi-channel semg measurement method,through collecting squat jump test means the subjects' minimum height,power take-off and electromyographic signal indicators,and then sorts through the experimental data and statistical analysis,provide data support for this research.Conclusions:(1)The method of dynamic tensile and proprioception neuromuscular facilitation practice can make immediate jump highly significant growth,proprioception neuromuscular facilitation + dynamic stretching exercises to instantly jump height was not significant,the influence of three kinds of tensile impact on instantly jump height pair-wise comparison difference was not significant.(2)The proprioception neuromuscular facilitation practice has obviously improved the immediate take-off power method,the dynamic tensile and proprioception neuromuscular facilitation + dynamic stretching exercises to instantly jump height was not significant,the influence of three kinds of stretching to instantly jump power two two compared the influence of the difference was not significant.(3)Dynamic stretching and proprioception neuromuscular facilitation law practice no significant impact on lower limb muscle integral electromyography,proprioception neuromuscular facilitation + dynamic stretching exercises can lead to a significant decline lateralis integral of the gastrocnemius muscle electromyography,but on medial rectus muscle,shares the lateral femoral muscle,muscle,glutes,and inside of the gastrocnemius muscle integral the biceps femoris muscle in his muscle power was not significant,the influence of three kinds of tensile impact on lower limb muscle integral electromyography pair-wise comparison difference was not significant.
