The Analysis And Optimization Of The 200 Meter Freestyle Turn Technology In The Modernpentathlon Sports Teams In China

Through Kistier system is used to provide technieal analysis software rind supporting hatdwaie,on China's modern pnentathlon team male and female athletes,a total of 9 people,freestyle turned and shot,and analyzed. Combined with data from the literature,expert interviews,and their own experience and practice,aiming at the problems of modern pentathlon athletes in national teams in turns,stapes of making water training method. Training content is divided into four stages,pool wall stage: before turning to see reference practice; f1ip turn push off stage: standing group practice,into the upper reaeles of the water when the tegiment body exercise,wator 10 meters in a prone position with swim to roll back foot positioning practice; coasting stage prone tic from the wall oi the pool body stretched straight. stieamline piactice; water stage: push off after swimming legs to 5 meters of water after exercise complete practice: water 10 meters race pace freestyle roll onto the water 10 meters technology practice. Through the above technical exercise test to the athletes of Freestyle turn each stage performanee,index was comparod before and after the experiment. Draw the following conclusions(?) conclusions1 our countiy modern pentathlon athletes in close proximity to the pool wall stage focus correction and optimization before turn 5 meters of swimming speed and tinned up in good effect,through more targeted training effect is more obvious2 our country modern pentathlon national team after kicking off the stage there still exists shottcomings,mainly after the turn of the tic from the angle stability is poor,betuuse of the action or in the adaptation,so to plav in the training and competition of stability is not enough.3 China's modern pentathlon national learn in. eriasling stage streamlinod maintain have greatly improved,the ability in control the body has been enhanced. But the water leg is still in a relatively weak state,on the one hand,is underwater leg in play when the body is prone to two Alice and frequency on tie othet hand the thigh is relatively slow.4 our country modern pentathlon national team in the water phase increase laiger,water in a modest distance,water front leg and hand cohesion study coherence.(?) Recomiendations1 in daily trdining,coaches should remind more athletes attention turned to the derails of tne action,to athletes to instill the importance of turned in the 200 meter freestyle, strengthen the athlete's own understanding on the turn,raise a level form the realm of thought.2 suggest coaches in training increased some about swimming leg exercise,so fat,China's modern pentathlon national team athletes aftet kicking off,underwater leg effect deviation ,shall inerease exercise,help the athletes to ennsni idate and continuo to improve the swimming leg action technology.
