Kinematical analysis of the takeoff preparation techniques for high jump
The authors carried out a statistical analysis on the technical videos and photos regarding the games per-formed by 4 excellent high jump athletes in the world,such as Soto and Mayo,and revealed the following findings: All the technical moves performed in the entire run-up process in Fosbury style high jump were prepared by the athletes in order to accomplish good takeoff;all technical links affected the athlete’s takeoff effect directly.By com-bining with sports training practice,the authors carried out a kinematical analysis on the characteristics of the take-off preparation techniques for Fosbury style high jump in such 4 aspects as the athlete’s run-up rhythm,takeoff leg support at the third countdown step,swinging leg support at the second countdown step,and takeoff support at the last step,and summarized the characteristics of different preparation techniques adopted by the athletes,such as step frequency type and stride type,as well as tilted support type and bended leg support type.
