Study On The Effect Of The Breakable Multi-pulley Traction Training On The Run-up Speed And Performance Of Long Jump

At this stage,the long-distance movement is developing in the direction of fast running,fast boarding,fast jumping,and high rise.Therefore,speed training has a great impact in the long jump.According to the division of items,long jump is a fast-powered sport.It requires high quality for the long-distance athletes.An excellent long-distance athlete must not only have good speed,but also must have a rapid explosive force.Both of them are indispensable.Therefore,in daily training,speed training has become the focus of most researchers and coaches.A large number of literatures have found that there are fewer methods for long-distance special speed training.Most training methods are based on the training method of sprint.It is impossible to combine the complete motion technology with physical fitness training(speed training),which is the aspect that the current long-distance speed training needs to be improved.As we all know,long jump is composed of four steps: running,jumping,vacating,and landing.Among them,running is the foundation,and taking off is the key.Scientific research shows that the impact of good running speed on long jump performance is 70%,and the study found that the utilization rate of Chinese athletes' running speed is far higher than that of the world's best long jump athletes,but the long jump performance is still compared with the world's outstanding long jump athletes.There is a big gap,mainly because the absolute speed of the long jump runners in China is low.Although the speed of the running speed is higher,the actual running speed is still lower than that of the world's best long jump athletes.This is the current situation of the long jump in China..Therefore,in order to improve the athlete's running speed,it is necessary to increase the absolute speed of the athlete so that it can achieve a higher running speed with a lower running speed utilization rate,so as to prepare for a quick take-off,in order to achieve a better long jump.The results are paved.This paper uses literature data method,video analysis method,experimental method,mathematical statistics method and other research methods to study the application of breakable multi-pulley traction training in long jump running ability and long jump technology.The influence of pulley traction training on the absolute speed and performance of long jump running,and the application effect,advantages and disadvantages of breakable multi-pulley traction training in long jump running speed training,in order to improve the research and application of long jump runningspeed training method in equipment.Thereby improving the scientific and effective training of long jump running speed training,and contributing to the development of long jump technical training.To summarize the analysis,the conclusions are as follows:1.The detachable multi-pulley traction training is to use the external force to force the athlete to accelerate the running,so that the athlete can complete the take-off under high-intensity load when the athlete reaches or exceeds his maximum speed.Kind of training.Pulley pulling is a more economical training method in speed training.The tractor can develop its own strength by the resistance given by the tractor in the running,and the traction is powered by the tractor.There will be a big improvement in speed quality.The correlation coefficient of the speed of 10 meters after the multi-pulley traction training is r=0.94,and the probability value of the significance test is P=0.04<0.05.Therefore,it is considered that the speed of the athletes before the experiment is 10 meters after the running(mean±standard deviation)9.22 There was a significant difference between ±0.21 and the speed after the experiment(mean±standard deviation)9.34±0.26,that is,the multi-pulley traction training experiment had a greater impact on the speed of the athletes after 10 meters.2.The principle of the detachable multi-pulley traction training is to use the inertia of the athlete's running,before the athlete takes off(usually three steps before the jump),the rope will automatically fall off,which can improve the athlete's running speed without hindering the athlete's take-off.It can improve the athlete's ability to take off in the case of high-speed running.At present,this is a relatively economical,simple and efficient training method to improve athletes' long-distance running speed and performance.In the experimental group with multi-pulley traction training,the probability value of the long-term test of the long-term test was P=0.002<0.01.Therefore,it is considered that the experimental group has a very significant jump before the experiment(mean±standard deviation)5.70±0.42 and 6.04±0.22 after the experiment.The difference,that is,the multi-pulley traction training of the experimental group has a significant effect on the long jump performance;the probability value of the significant test before and after the training of the conventional training group is P=0.068>0.05,so it is considered that the control group has a long-term performance before the regular training(mean± There was no significant difference between the standard deviation)of 5.61±0.48 and the post-test long jump performance(mean±standard deviation)5.67±0.47,that is,theconventional long jump training in the control group had no effect on the long jump performance.3.The principle of the multi-pulley traction can improve the speed of the athletes' running speed,mainly to improve the running speed of the athletes of the school long jump team,and the impact on the stride is relatively small.Compared with the conventional long jump training,the athletes' run-up speed and long jump performance of the multi-pulley traction training are more obvious than the conventional long jump training,and the angle of lifting is closer to the optimal starting angle of scientific research,18-22°,especially for the previous For athletes with excessive take-off angles,the improvement is more obvious.In addition,the take-off time is also significantly shortened,and the pedals are more active and fast.4.The detachable pulley traction training has both advantages and disadvantages.Its advantages are simple,economical,high-efficiency,simple and easy to operate,and the effect is obvious.It can be used in a wide range of objects and has a high penetration rate.The biggest advantage used in the competition is that it meets the characteristics of the long-distance running of the long jump project: uniform acceleration movement,which is currently impossible to use with the tractor.The shortcoming is that the ability to measure the traction force can not be accurately measured.It can only be controlled by the athlete's 30 m acceleration run and the speed of the 100 m run.In addition,the use of the device requires the athlete's physical quality to be relatively good and has certain The basics of long jump,that is,all aspects of long jump technology have a certain foundation.
