Analysis Of Pedal Accuracy Of Male Long Jumpers

Pedal accuracy of long jump is one of the important technical aspects that determine the long jump athlete to win the match or get to continue to participate in the competition.The quality of this technical link and the degree of mastery of the players is a long time,but also a long time to study the problem can not be solved in a very good exercise.The pedal accuracy of long jump problem exists not only in grassroots athletes.It also exists in the high level of world-class athletes,in the technical aspects of the problem is a presence in senior and junior athletes with generality and universality of the problem,is a problem to be solved urgently.Held in China in 2015 the World Athletics Championships in the long jump competition,because of problems with the pedals accuracy enable athletes missed the good result in the phenomenon abound,many outstanding athletes are on the pedal link appeared a lot of mistakes,which lead to unsatisfactory performance.Project in the long jump competition often because a small mistake and subtle gap will lead to changes in the performance of athletes during the games,many physical qualityoutstanding and high level of training athletes often in the game because the pedal inaccuracy of mistakes caused the failed to jump out of the better grades or lose to win a medal chance.One of the reasons in China held some sporting events and athletes of long jump run-up relatively poor accuracy,low success rate,which is hindered China’s level of long jump to further improve.Shanxi college sports games is a higher specification of the games,is hosted by the Shanxi Provincial Department of education,the high standard of sports events.The athlete covers(outside the training of sports majors in high level athletes,sports education professional students professional(systematic study of curriculum in high school but not in the national register)athlete and student athletes.Games.In view of the phenomenon of Shanxi Province,high school track and field will long jump athletes in the game in the lower stability of long jump run-up and jump the low success rate analysis,looking for athletes in the game sports achievements existing problems,in order to improve the performance of athletes during the games are proposed.The existence of these problems should be fully aroused the attention of coaches and athletes,and it is worth to explore.Through the research of this paper,we get the following conclusions:1,in the tournament,the top eight players were 34 times jump have 13 times jump no accurate set foot on the springboard,accounted for 38.24% of the total number of jumps,of which there are two players in the final three jump all foul,the long jump athlete pedal inaccurate phenomenon is more serious,especially is moreobvious in the last three jumps.2,the top eight athletes have three athletes using the standing position of the starting position,there are five athletes using the way of starting between the road.The standing start way athlete pedal accuracy rate reaches 71.43% and use moving starting pedal accuracy is 59.26%,to see the standing start pedal accuracy is higher than that of moving starting mode.3 after starting an athlete run-up three steps ahead is the total length of the fluctuations and the pedal accuracy,there was a significant difference(P < 0.05),former athletes before the three steps step size and the standard three steps step fluctuations smaller,pedal accuracy rate is high.On the contrary,the pedal must accuracy is lower.4,eight athletes poured four step,down three step toe plate from the standard difference and final step toe plate from the standard deviations between the correlation coefficient is relatively small,but second step toe plate from the standard deviation and standard deviation of the correlation coefficient is larger,and between the two in the p value is less than 0.05 away from the final step toe plate,which can be seen down second step toe plate distance athletes accurate footboard with highest correlation is key to athletes accurate footboard.In the run-up to the last three steps,step adjustment methods vary from person to person,the step change has three conditions:(1)3 < 2,pour 2 >pour in 1;(2)pour 3 > 2,but 2 < 1;(3)3 < 2,pour 2 < pour 1.Between the last two steps and the difference of Tata accuracy of correlation analysis,can be seen there is a significant difference(P< 0.05)between the two,smaller difference between the last two steps,pedal accuracy rate is high.On the contrary,pedal accuracy is low,but on the difference of the last two steps and athletes of long jump result analysis point of view,between the last two steps and the difference of long jump result does not exist significant difference(P > 0.05),that step changes of the last two steps not measure can achieve good results.5,athletes in the competition the first three steps stride is not fixed to the run-up speed instability,which leads to the instability of the run-up rhythm,in the run-up to the final four steps appear deliberately increase,narrowing the stride or incompletely steps phenomenon,increase the instability of the pedal.In view of the above conclusions,the following suggestions are put forward:1,players usually training,regardless of what kind of starting position,should control the starting posture adopted,especially the moving start athletes,should be in the starting control good body posture and the accuracy of the logo for the first set foot in.2,the athletes in the run-up to strictly control the starting stride the first three steps and three steps ahead is the total step,in the game as much as possible will first three steps step and usually error between the training of fixed step size control to minimum,which is convenient for the pedal error to a minimum.3,the coaches of athletes in final four steps of training should be attention in final four steps of toe plate distance training,each step of fixed athletes placement and the distance between the springboard.To approach the last three steps of the step changesaccording to the characteristics of athletes,but the last three steps of the fixed step size should give fixed to ensure that athletes in the last three steps approach does not appear to deliberately pull big stride or down in small steps.In the last two steps of the training,the coach should try to reduce the difference between the last two steps to ensure that the athlete can finally move the pedal accurately.4,run-up rhythm training to stressed after start of a three step approach of stability,run-up in final four steps of the stability of lay the foundation for and ensure athletes can accurately on the board.
