The Kinematics Study S For College Basketball Games Players By Middle And Long Distance Stop-jump Shot

Pull-up jumper is the use of offensive players on the move and fast emergencystop off two consecutive actions to get rid of the time difference defender method toachieve a jump shot shooting purposes. In this way a better use of the offensive andthe law of basketball, players can fully reflect the fast, flexible features. But thepull-up jumper is a combination of many technical movements with a single action.How, under conditions of intense confrontation, more harmonious and how thesetechnologies used in combination with a single, more coherent, making it difficult tostudy the technology.This paper mainly for outside players scram ball jump shot techniquebiomechanical study, biomechanical characteristics of its structure the action, tryingto get the data through sport biomechanics method to analyze basketball players in theprocess of long-range pull-up jumper to locate basketball players in the sportbiomechanical characteristics of each stage. Northeast Normal University basketballgoal is to use this technology professional athletes in training to provide visualreference data, and provide reference for sports training and teaching.In this paper, the experiment before consulting the relevant experts andbasketball sports biomechanics experts to determine the long-range pull-up jumperbasketball player acquisition parameters, including design of experiments, contactplayers and venues to borrow. Experiments to Northeast Normal Universitybasketball team four guard members as subjects, using the literature, expertinterviews, experiments, mathematical statistics and logical analysis of researchmethods, data for this experiment were video acquisition, post-processing andanalysis.After six trips to four players in the long-range pull-up jumper technical actionshooting acquisition, the experimental data obtained early, post-processed APASsoftware reprocessing, come to basketball players jump pull-up jumper and steppedjumper trip the main technical action kinematic parameters, including time entry, thecenter of gravity position, velocity and joint angles. Found that pull-up jumper jump in these four aspects with different stride jumpstop, embodied in from the data:(1) the temporal characteristics, pull-up jumperjump ball an average of the entire operation is completed0.76s, which three stagesproportion of the total time was31%,56%and13%, while the pull-up jumper stridecatch average time to complete the entire action0.83s, the three stages of the totaltime compared to43%,36%and21%. By comparison, the jump ball pull-up jumperat the ball with a pull-up jumper less than stride, as soon as possible if the athletewants to require the use of a jump shot pull-up jumper.2position on the center ofgravity of Athletes: gravity athletes in action during the height has been a change inbody weight buffer stage performance at the lowest point, vacated shot stage at thehighest point. Which stepped trip jumper vacated height above the jump shot pull-upjumper, athletes height advantage if you want to get space on the need to adoptstepped pull-up jumper.3speed characteristics: pull-up jumper and a jump ball catchstride pull-up jumper in the buffer and stomp off process, vertical jump height affectthe speed of the athlete’s center of gravity is more obvious.4buffer stage, the jointangles of the two pull-up jumper in the buffer action to achieve the fullest, stomp offinstantly, athletes hip, knee, ankle angle reached the maximum during the entiremovement, the pull-up jumper action relative stride pull-up jumper in the buffer andjump kicking actions more fully. More conducive to high athletes get vacated height.Shot in the vacated stage, an average angle shot pull-up jumper jump ball of62.741oand62.84o, or less.
