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. |
