Experimental Study Of Teaching The "Core Rate" Of Speed Glide Shot Put With Lower Limb Exercises Means The Design And Implementation

Glide shot put is currently China’s track and field athletics students learning courses in a key project, due to its technical complexity and the objective requirements of the physical conditions, making the learning process of students in technical error prone to a variety of phenomena especially with the last hard Sliding and speed the process of convergence reflected in question, has been the technical difficulties Shot Put back the teaching process has not been effectively addressed.This article from improved teaching glide shot put with technology start innovation of the “core rate” means the application of lower limb exercises to speed glide shot put with teaching, to solve glide shot put during the Learning error due to lack of speed caused the emergence of Steps and Last Strength convergence pause, etc,as soon as possible to encourage students to master the correct glide shot put Shot Put technology.In this paper, the literature, found in previous studies to be improved by studying where previous studies, combined with the “core rate” concept to determine the direction of this paper; after determining research directions based on the “speed of the core” concepts related to the design of teaching methods applied to the experimental teaching methods through the teaching process; teaching after the end of the experiment the experimental group and a control group of students at the time of image capture students get complete glide shot put complete video information technology, then by image analysis of the experimental and control groups of students to parse the video data; use of mathematical statistics for video data analysis experimental group and control group students in statistics, find out the existence of correlation between the writing of this paper is to provide data support.According to the “core rate” teaching philosophy at several were designed to develop students Leg Speed teaching methods are: lower limbs fixed in place positive Shot Put; Tiaoxiang jump combination exercises; Tiaoxiang edge action done in suit Shot Put; the use of continuous power Slippery slope foot fast access floor exercises;Tiaoxiang jumped after the last pick of the technology practice hard; swash plate resistance exercise; slide ramp from the plane to complete a full technical movement exercises; exercises power ramp, through the analysis results the following conclusions:1.Ramp exercises help improve student body glide shot put focus speed has a significant effect, promote the improvement of the human body during the complete technical focus speed; the lower limbs fixed in place positive Qianpu Shot Put Shot practice means to move away from the effect of the increase is significant.2.Tiaoxiang force exercises for legs kicking significant effects. Tiaoxiang practice means to improve student Back Sliding the right foot when the speed of a pair effect is obvious; Tiaoxiang means two exercises to improve student Back Sliding force fast kicking leg from the knee instant speed to have a significant effect.3.Back Sliding learning techniques help students falling leg swing positive interim step while on the slopes, improve convergence and transition steps Sliding.4.Tiaoxiang jumped pick last exertion exercises help students quickly grasp glide shot put transitional step technology to shorten the transition time step; Slippery slope plane exercises help students experience the full technical step transition process technology, significantly improve students’ Sliding Cohesion and finally force the body center of gravity velocity.5.Shot Put in place Tiaoxiang edge tools to help students practice the formation of a reasonable standard of action beyond the instrument, will help improve student support during the final exertion kicking leg brace awareness, help improve students’ final leg force when the force of the knee and hip joints kicking transfer speed,strengthen coordination and hard to force the legs supporting leg.
