Applied Research On Swim-relay Feedback Instrument In The Relay Start Training

As swimming competition level unceasing enhancement, swim relay technical level is also in constant perfect, in tension, fierce swim relay competition, the athlete handover of the amount of time between great for the team to swim the relay RACES overall influence greatly. How to shorten in game 2 players handover great time, improve the team competition result, must on 2 players relay on technical put forward higher requirement, requires not only the runner when answering the stick with accurate space directional, but also to handover time, can be in judgment accurate relay RACES this complex environment for your partner's place to make faster response, and make great athletes demand more positive runner to make for more accurate timing handover great judgment, which makes 2 players, making the transition to connivance grass-stick technique is more stable, the stable transition after repeated grass-stick technique training is formed.How do you know 2 players when consumed in the handover great time, through the time the information feedback to prove 2 players the stability of the handover grass-stick technique? Therefore this research by using swimming relay feedback device, test 2 players handover great time freestyle relays. In preparation for the 11th the swimming team of shaanxi province during the swimming events relay RACES through the experiment test methods using swimming relay feedback apparatus are tests of the two schemes to stage a:project, the judge athletes choosing test underwater players arm; Scheme ii, on the choice of the athletes head and arm underwater athletes with test, the way get original data statistics and analysis of each scheme between the players the handover time was analyzed, meanwhile to between two schemes are analyzed, and through the national swimming performance announcement of shaanxi province, the teams and other ShengDui 4 x 100m and 200m freestyle and 4 x 100m medley and analyzed, meanwhile national games 4 x 100m in shaanxi province 200m freestyle,4 x 08 swimming championship and analyzed.The results of the study indicated that by swimming relay feedback instrument based on swimming relay training applications, through the test two schemes by choice, according to the results of the time before the judge a great athlete head and arm combining training than used judgment before training a great athlete arm, so the way in later swim relay training, this research suggests that should be used judgment of a great athletes before the head and arms training combined way; Through the national games, shaanxi swimming team that scores announcement in 4 x 100m and 200m freestyle relay connection time to less than other ShengDui, and shaanxi national games 4x100m and 200m freestyle after jumping time than 2008 swimming championship, then jump right around the time shorten 1s. Fully explain shaanxi teams use feedback apparatus are tested repeatedly training, shorten the handover great connection time and improve the technical level, thus swim relay team of shaanxi province of swimming relay make technical level reached the front in the whole country.
