Research Technology Kinematic Features On Take-off Trampoline Man Two Weeks Of Online Our Country

Trampoline project men’s and women’s single two events in the2000Sydney Olympics were classified as official event, has developed over the last50years in view of the international, China has carried out in1997in sports, and so far only15development course, the training theory, training methods and action technology of enough detail and perfect.Action of take-off technology is both a movement to complete the foundation that decides the movements of the complete quality and action of the use of technology, and the more take-off technology key. Double somersault is difficulty movement in our country that is the action of the trampoline basic, this article in view of the trampoline man double somersault in our country of take-off technology that one key link, each joint Angle to the body, your center of gravity displacement and time was analyzed, the man two weeks this online take-off technology in our country the kinematics characteristic, engaged in the movement for trampoline coaches and athletes reference and lending.This research mainly adopts literature method, expert interview method, and the high-speed photography method, video analytic method to xi’an sports college athletic trampoline team five men who sports and the completed double front and back skills, tuck position, pick position, straight position in our country as the research object. The application of Lille Sports Biomechanics Analysis System of Competitive Sports College in xi’an APAS who trampoline team five men sports online double somersault in our country of take-off technology analysis and research, conclusions and Suggestions are as follows:Conclusion1. Double somersault ahead of aerial tumbling down the body and the group take-off technology in the net Angle and away from the nets Angle no significant differences.2. Back double in our country main difference between the net Angle and away from the nets Angle, movement characteristics have no significant difference of tuck position and pick position, both with the straight position have significant differences in the main performance from the nets Angle into the horn, the former net Angle and are less than the latter from nets Angle of view.3. Doing double somersault as you roll in our country, the number of weeks how much the swivel the take-off technology into and from nets Angle of the influence on the choice no significant change. The swivel weeks increases, the pressure nets depth increases.Suggestions1. The coaches and athletes in training or practice in our country front double somersault to different action (straight position except), from the perspective of network access and can not distinguish.2. The coaches and athletes in do two weeks when our country back training group, tuck position and pick position can be put down our country movement training together, doing straight position action training, we should pay attention in the net Angle and the distinction between from nets Angle.3. The coaches more leg strength training, increasing the net and increase the intensity of the push to stretch pressure nets depth, for three weeks and over our country and more weeks swivel to build the foundation.
