Research On The Influence Of Elastic Belt Training On Sprint Running

With the continuous development of modern sports,sports performance is constantly updated,more and more scientific training of the high attention of the majority of sports,in order to improve the athletic performance of athletes,coaches constantly innovative methods,innovative means,this training method-a new elastic belt training,as a special physical resistance training through training,the weight of the athlete's elastic and dynamic resistance,athletes in training to control resistance,can effectively by increasing the muscle dimensions and muscle strength to promote the speed,power,endurance,the elastic belt of economy,simplicity,effectiveness is widely recognized and fully affirmed the domestic and foreign professionals who engaged in sports work.But in our country,using elastic belt training is not very wide,the relatively mature elastic belt training most used in the national team,professional sports teams and other high level training;sports school and University Amateur Training because of the expertise and equipment facilities because of the lack of training of the elastic belt elastic belt stay the low level of training in this aspect.Furthermore,through access to relevant literature,elastic belt training is widely used in swimming,canoeing and other projects,especially in track and field sprint pole vault in the sprint with no,even in some literature wrote elastic belt training is overview,not applied to elastic belt link training and special features to improve the technology,has less effect on sports performance;so the combination of the above factors is suitable for the special technical training method of elastic belt,elastic belt help can make training application wider and more improvement on sprint training.This paper uses literature,expert interviews,questionnaire survey method,experimental method,mathematical statistics method,6 athletes of Yunnan Normal University Sports Institute 100 meters sprint training level two of the elastic belt training adopted elastic belt training method in design is the implementation of a special combination of technical characteristics of sprint after 16 weeks,the elastic belt training,the training of athletes before and after running special technology,results were compared and analyzed,the purpose is to find and close contact of the elastic band sprint training method.The results of this paper are as follows:1,from the sprint kinematics analysis of special technical data can be seen: theplayers support the leg moment and from the instant of lower limb joints angle,swinging leg swinging hip joint and knee joint angle,the location before and after hip joint projection distance,trunk anteversion,upper limb swing angle on the way to run several special technology,for before and after training data were analyzed: by using the elastic belt training in dash running,the runners of the special technology tends to be reasonable,that,by combining with the short run midway run special technical elastic belt training method,not only improve the the athletes in high speed running in running special technology,also effectively improve the performance of the dash.In 2,the increase of analysis of change of training before and after training 100 meters performance and the special technical training methods: through the elastic belt in sprint training combined with special technology,the athletes of the special technical training increased significantly,and after 100 meters scores have significant difference.From now on,it can be concluded that the method of using elastic belt training in the short run on the road can effectively promote the improvement of the special performance of the sprinters.3,based on the statistical analysis of 100 meters scores and the number of steps before and after the training,the training of athletes after training 100 phase 100 meters before the better performance,the number of steps has been reduced,after training before the training frequency is relatively faster,that in sprint training in the implementation of elastic belt training,not only improve the athletes step,and relatively improve their stride length and stride frequency,the coordination,the dash technology is more reasonable,improves the running speed.In sprint training using a combination of special characteristics of elastic belt training methods,not only the athletes after training each sprint specific technical features need to be able to match when the special skill,but also greatly improve the sprinter's athletic performance,which can meet the special needs of the movement with elastic training method,let the athletes in high speed running will run in the way special technology play more economic effect.
