Experimental Study On The Effects Of Three Different Forms Of Load Stimulation On The Explosive Power Of Lower Limbs

In sports training,only rely on their own resistance is difficult to obtain good training effect,often rely on outside instruments to influence the body’s muscles,development of lower limbs explosive force is one of them.Under the background of the study of science and technology,the explosive force training equipment emerge in endlessly,the training effect.We are the most commonly used traditional barbell development lower limbs explosive power,it has a complete theory and method of training.With simple operation,convenient,easy to grasp.Keiser outbreak of gas resistance training instrument is to use gas pressure as power resistance training equipment,its characteristic is when using can evenly and smoothly transfer positive or negative resistance,reduce the load on the athlete’s muscles,joints,ligaments and other connective tissue,cut the chances of injury to a minimum.Cormax explosive release at the end of the training equipment using liquid pressure as a resistance training equipment,simply put,is to load,its characteristic is to train more close to the special action pattern,can keep increasing speed in the process of the whole movement.Studies have shown that lower limbs explosive under 50% RM load development,keiser outbreak of vapor lock power training instrument training effect is superior to the traditional barbell sets.There are also studies prove the squat jump after 10 weeks training tests,cormax explosive release at the end of the training equipment training effect is superior to the traditional barbell sets.And among the relatively less.From three different load squats the purpose of this paper is to stimulate the perspective of form,combining with the characteristics of athletes lower limbs explosive development,main use Just Jump jumping mat as a test of lower limbs explosive power tool,through the comparison of before and after the experiment method to discuss three kinds of equipment for the development of the merits of the lower limbs explosive power.This study used the literature material law,won a large number of domestic and foreign literature about development of lower limbs explosive power,for the fruit of the research design and experimental analysis to provide adequate theoretical basis;In tianjin sports college graduate department of 18 students as experimental object,the experiment is divided into three groups: Ⅰkeiser outbreak of vapor lock power training group,Ⅱtraditional resistance training group,Ⅲgroup cormax explosive release at the end of the training group,experimental training for eight weeks,before and after the experiment through " Just Jump " bounce pad to all the participants of SJ and CMJ situ hang time of vertical Jump,fly high,four consecutive reaction time,the average height of suspension of vertical Jump,explosive index test,analysis of three different squats stimulus form after the change of the indicators,participants in the end,the following research conclusions:(1)Cormax explosive release at the end of the instrument after eight weeks of training after the intervention,the subjects leg extensor group under the spin state in advance all of a sudden start shrinking capacity and centrifugal rapid conversion to heart contraction,growth is better than the other two devices.(2)Keiser gas resistance training instrument after 8 weeks after the intervention,the subjects leg extensor group under the spin state in advance all of a sudden start shrinking capacity and centrifugal rapid conversion to heart contraction,growth rate higher than the barbell training instrument,below cormax explosive release at the end of the instrument.(3)The barbell training instrument after 8 weeks after the intervention,the subjects leg extensor group under the spin state in advance all of a sudden start shrinking capacity and rapid transformation loading centripetal contraction ability enhancement,slightly increase minimum increase compared with other two kinds of instruments.(4)After eight different way to training on Wednesday after the intervention,and then to just jump bounce and the isokinetic muscle testing,Cormax explosive release at the end of the instrument training effect of lower limbs explosive power is better than the other two kinds of training equipment.
