The Studying Of Run-up Absolute Velocity Utilization Rate To Our Country’s Excellent Male Pole Vault Athlete

In today’s excellent man pole vaulter atheletes, the instantaneous velocity of Holding Pole Run-up and take-off has become the main factor to affect the final results. how to control and grasp the Holding Pole speed and rhythm, will decrease the loss of the instant level run-up speed in the instantaneous of take-off, and improve the Utilization rate of the absolute velocity of the run-up,that is the core problem in today’s Researches.In view of this, the subject taked the run-up absolute speed utilization rate of the man’s pole vault as the research objectives, through the literature and interviews Summed up the Influence factors of the Utilization rate of the absolute velocity of pole vault run-up; through field tests and video analytic method obtained Specific data of Feiliang Liu (former national record holder)and Yang Yansheng (the current national record holder) who represented the elite men’s pole vault athletes of our country. Thtough Comparing The part date of the world records maintained part Bubka (former Soviet Union) and former world record holder Vigne Long (France) with the Specific data of Liu and Yang, obtained the Influence factors of the Utilization rate of the absolute velocity of the man’s pole vault in our country.Through research, obtained the conclusions as following:1The "utilization"of the run-up speed Utilization rate has two connotations:First connotation is the use of their own maximum speed level in the run-up process, referred to as the utilization rate of the run-up speed; Second connotation is the ratio of the the horizontal velocity of the The gravity center body and the run-up controllable speed before take-off. The run-up speed is the instantaneous speed before take-off, and the the number to compared is the maximum controllable speed in the run-up, rather than the maximum horizontal velocity in the run-up. This concept applies to the long jump, and the same to the pole vault.2The main Influence factors impacted pole vault athletes absolute run-up speed utilization rate included the approach distance; the run-up starting and accelerated Modes; accuracy of the run-up; run-up rhythm; the abilities of grasping the body gravity from run-up to take-off; holding pole technology in the run-up; plug hole technology; take-off; psychological factors and special qualities in the upper and lower extremity strength and physical coordination.3The main factors restricted increasing of our country men’s pole vault run-up absolute speed utilization rate are about the six points as follows:First, domestic players relatively poor coordination of foreign players in the final steps of approaching and drop the pole, held pole action, especially the last two-step run-up convergence was bad;Second, from the point of the grasp of the run-up body center of gravity of the final stage of the domestic players and foreign players there is a gap:Yang Yansheng run-up since the penultimate step right foot to its body center of gravity changes appear larger differences, its run-up to last step left foot to body weight re-emergence of large fluctuations, the last step run-up to take-off leg kicking away from the the ground instantaneous body center of gravity height, take-off direction of the two domestic players are on the side rather than the front upper direction;Third, the domestic and foreign players greater difference in grip pole height and pole pole pound class weight difference between the domestic players is significantly less than the foreign players. The domestic two players on these two indicators is also working to improve, but at the same time increase the psychological pressure of the players, the run-up the last few steps to produce a psychological tension, and ultimately affect the run-up absolute speed utilization;Fourth, Yansheng Yang plug hole timing than two foreign players and Feiliang Liu plug hole as early opportunity, and Yang Yansheng is take off the way "ran into the pole, to force pressure Pole", cause before takeoff speed less One of the reasons for the slow;Fifth, while Yang Yansheng is "ran into the pole, the force pressure pole-style take-off hand, but the take-off point or distance point projection point remote from the take-off distance, the take-off of the two players close with them the run-up speed, the run-up utilization of absolute speed, grip pole highly correlated, Yang Yansheng limited takeoff way thus becomes more recently;Sixth, the absolute speed of our players or less, comparatively speaking, the larger the gap between the quality of the power of the upper and lower extremities, causing relatively large angle in the final run-up the backwards action and final acceleration takeoff confidence; coordinated the training of domestic players start night, less training total.
