The Experimental Study To Hang Long Jump's Teaching Effect Of The Plvometrics

Long jump is one of the main items of physical education and athletics competition,according to the air movement can be divided into the squat,and walk straight jump,and long jump teaching in our college and professional sports college track and field course to walk and stand type,the body type.But with the reform of the teaching syllabus,gradually reduce the number of skill teaching,resulting in short time,heavy task,difficult to grasp the situation,therefore,this study will be rapid expansion composite training into straight jump teaching,the purpose is through experiments to explore the effect of rapid expansion of composite training stand long jump teaching effect,to pave the way for the future development of the new teaching method,and provide new training methods and theoretical reference for straight jump teaching.This paper mainly adopts the methods of literature,questionnaire,expert interview,mathematical statistics and experimental method,study of rapid expansion composite training applied in teaching activities to prepare to jump the part,randomly selected 2 classes(42 in total)of male college students as the experimental object,will be divided into the experimental group and the the control group.The experimental class and the control class respectively through 8 class exercises,for its special quality and straight jump skill evaluation,test standard results,the data were analyzed and summarized,finally draws the following conclusion:1.Plyometrics by shortening the eccentric concentric contraction coupling time,increase the muscle power output,enhance the strength of lower limbs,so as to improve the students' three class standing long jump and 20 meters Time Hop performance.2.Plyometrics has no obvious effect on improving the performance of 30 m accelerated running.3.In the process of the Hong Long Jump teaching,the combination of the rapid stretching exercises can improve the teaching effect of the long jump.4.Plyometrics can improve the mastery of skills,improve the level of technical action and improve the quality of teaching through the positive transfer of motor skills.
