Researching The Technical Features Of Outstanding Female Trampoline Athletes Do Back Flip Turn Class Two Weeks Early

The trampoline is a technology winning project, at the same time, it’s a difficult and beautiful performance, developing action technology is the foundation of training, transfer class backflip two weeks early is the main action in women’s trampoline competition, and the type of action is indispensable. The video will adopt the International Gymnastics Federation for the 2011 trampoline World Cup Series (Wu xi station) and the 2012 International Gymnastics Federation trampoline World Cup Series (Tai yuan station), and elects outstanding Female athlete backflip turn two weeks earlier class action, to carry out such an action stage division and index selection, operate of all aspects of kinematics analysis, combined with experts and scholars on the pair trampoline action research, improving backflip two weeks early success rate of the class action is completed turn, it not only reflects the movement difficulty value, but enriches the type of action, to optimize the training has an important role.Mainly using of literature, video analysis, expert interviews and other methods, for outstanding female athlete transfer class action backflip two weeks early, consider carefully every action, screening, seeking to turn the class action backward two weeks early comprehensive and systematic study of technology, while providing some of the theoretical and practical application of reference for training.The main conclusions are as follows:1.Two weeks earlier class action backflip turn quantitative evaluation indicators include six indicators,such as movement time, movement height, action angle, flip speed, the speed of development of the body, twist rate, etc., related to several aspects of time, space, angle and speed.2.Backflip two weeks early turn off class action technology includes posture forming techniques, the body postures form technology, exhibition technology, keep a straight body somersault whereabouts technology, prepare to touch the net technology, but it does not involve the body in direct actions.3.Backflip two weeks earlier should keep a certain network area when contacting the net,and the best network angle is 85°-87°, Put the body to the center of gravity of the body to adjust to just above the anchor, and enhance the net effect of pressure. By analyzing, it’s visible that the main reason of the pressure is not sufficient is the network angle is too small.4.Two weeks earlier class action backflip turn away from the net should choose the right corner off from the network, the most reasonable off-grid angle 58°-65°, move the arms, head to upright, Avoiding to appear off-grid angle is too small. By analyzing, the upper body down prematurely is the main reason of resulting in insufficient pressure network.5.Two weeks earlier class action backflip turn somersault before the end of the first week of the formation of body posture, the somersault speed should be as fast as possible.By analyzing, the outstanding female athletes’speed somersault is between 325°/s-556°/s, and it’s often accompanied by the somersault twist6.Backflip two weeks early in the development of body transfer class action stage show body the faster, the better, in order to maintain a straight body whereabouts a longer period of time to provide a guarantee. Generally speaking, the outstanding female athletes’exhibition body speed is between has significant differences.It directly affect the completion of the quality of the action, which needs to adjust the time distribution at different stages, adjusting indicators at different stages to reasonable.
