A Comparative Study Of The Speed Changes Of The World's Best Men's Speed Climbers

With rock climbing project to join the 2020 Tokyo Olympic Games,rock climbing of China and the world will get unprecedented development.Athletes will greatly improve the athletic level,and the rock climbing will be more competitive.Speed climbing relies on its characteristics of strong visual impact,stimulate the adrenaline of the audience,attract more audience,become the most important part of the decision to enter the Olympic sports climbing list.Speed climbing will be much accounted of talents in popularization,personnel training and scientific training.Athletes want to achieve a high level of performance,not only need to have the corresponding speed climbing movement quality,more important is to understand the rules of speed the process and characteristics.Athletes should be targeted training in order to achieve better performance.This research takes the representative whole world excellent male speed rock climber's entire speed change as the main line,carries on the segmentation and the thorough comparative analysis to the athlete entire speed process.Study on the whole speed variation of the world elite male speed rock climber by means of sports literature,image analysis and mathematical statistics.Analyze and summarize the main factors affecting the speed climbing.Then summarize the data and reveal the real problem.The research conclusions are as follows:1.In order to better for speed climbing to the study and analysis of the characteristics of speed change,this article will speed climbing process is divided into four stages:The stage of climbing,Accelerated stage,Maximum speed stage,Speed keep stage.This way of piecewise conform to speed climbing kinematics characteristics of the project,also conducive to further the speed climbing speed change characteristics of all the research and analysis2.The rapidity of stages of reaction velocity influence on the performance of the account for about four percent in speed climbing project.The reaction speed in the climbing stage is very important to the final performance.Reflect speed continue to be breakthrough is the goal of speed climbing athletes.Targeted training for athletes from the climbing stage reaction speed is particularly important in sports training.3.The acceleration stage of speed climbing is closely related to sports performance and both has an important influence on sports performance.Elite athletes in the acceleration phase is more inclined to pursue as soon as possible to achieve higher climbing speed,find their own accelerated rhythm,thereby achieving excellent performance.4.The maximum speed is a necessary condition for speed climbing athletes achieved excellent results but not sufficient condition,athlete's goal is to decrease the speed of slow and small amplitude;under certain conditions,players enter sooner to the maximum speed and speed maintain stage,the more likely to obtain excellent sports results.5.The factors that affect the climbing speed of speed climbing athletes are athletes'technical characteristics and sports fatigue factors.The athlete technology factors,including the use of rock climbing speed on the track,motion connection technology,the ability of athletes lower limb strength and body coordination to relax,these factors have very important effect on athletes speed climbing;sports fatigue factors including central fatigue and peripheral fatigue,compared with the peripheral fatigue,central fatigue effects on athletes climbing speed is greater.
