Study Of Kinematics And Dynamics Analysis Of Track Start Of Elite Swimming Athletes In Shandong Province

The study on the use of foreign Kistler Force platform,for the first time thr-oughthe kimematics and dynamics of two sports biomechanics indexes,to carry out atheletrack start and grab start of province,and discuss forward start and backward start indynamic advantage.This is the first study from twoa-spects of kinematics and dynam-ics and of track start swimming,find out mypro-vince outstanding swimming atheletof the technical advantage anddisadvantage In order to understand the essence of te-chnology advantage provide theory for the coachers scientific training.The departure time,flighttime,angle of knee joint kinematic parameters and themaximum force and atheletes from the step value,force time and kineticpara-mertersthrough the test.Based on the above experimental results analysis,get the conclusionof the study.The main conclusion are as follows:Shandong Province Swimmers starting platform technology exists muscle reactiontime rather long hind knee angle starting block small forward starting block legskicking force is small, the angle of instability into the water, into the water a shortdistance downstream, underwater fight Tuixi joint angle, the frequency of slow andother issues.Since starting players crouch adopted immature technology, some action is notfinalized, the proposed master reasonable angle of the knee, give full play to pull thehand pedal power station platform role and feet, rapid start, a long time to overcomethe stagnation Taiwan weaknesses. Through analytical biomechanical kinematicsdynamics of crouching departure, the proposed aid training aids players take atargeted approach to the technology training, strengthening exercises swimmers legstrength, can effectively improve the athlete’s departure quickly results...
