Kinematic Analysis Of The Take-off Of The Different Levels Fosbury Flop Athlete

Objective:The kinematic analysis is an important means for the movement of technical analysis and diagnosis, the purpose of this paper is to be resolved by three-dimensional high-speed technology video of different grades of High Jumpers stage, eight movement to transport the kinematics of take-off technology indicators,these kinematic indicators for horizontal and vertical comparison, and summarized the inadequacies of the different levels of athletes, from the kinematic point of view, to identify the problems of the eight athletes in the take-off technology for the athletes after training technological improvements to provide more accurate data reference for the training of coaches to provide a theoretical basis to improve the technical level of China’s high jump athletes to improve their theoretical basis.Methods:Using literature, interviews, mathematical statistics, logical analysis and comparative in this paper, analysis of eight different levels of men’s high jump athletes jump.Conclusion:1. Played an important impact of the run-up level of speed changes on take-off process of the kinematic parameters. The level of high-grade athletes significantly faster than low-grade athletes, the take-off the relative difficulty increases.2.Although the two athletes of different levels of height there differences (H1), but reflected in the percentage of the H2and the height is very close to the height for the jump and effect there is no direct correlation between the H3is a direct reflection ofJumpers effect and over the bar an important indicator of the performance of high-level athletes in this regard is very clear.3.Three high-level athletes buffer stage to show an instant hip angle larger and larger buffer margin (maximum buffer instantaneous angle is small), have a certain ability to jump instantly to dare to reach take-off leg, and take advantage of the larger hip flexion to obtainthe effective distance of the muscle work.Low levels of athletes subject to capacity constraints, lack of performance in this regard.4.Four high-level athletes in the buffer longer than low-level athletes short, indicating that high-level athletes is a quick take-off, kicking rate is relatively low-level athletes longer buffer time.5.Technique of Swing Leg can be seen high-level athletes leg folding technology is good, but smaller swings.Low-level athletes in the take-off phase of swing leg big leg folding and late swing timing.6.From the vertical arms swing speed, high-grade athletes are crossing his arms and swing technique, high-level athletes upper limb swing faster than low-level athletes, low-grade athletes on the lower limb swing vertical velocity ratio imbalance, Affecting the overall swing.
