Study On The Technique Of Pole Vault "Human—Pole" Synergetic Characteristics

Pole Vault event is a typical "human—object" interaction of sports,sports t echnology often determine to "people" and "objects" synergistic effect.the"huma n—pole" of the elements of time and space as the research object,to the worl d high level athletes of the technical characteristics of an object by using the theory and empirical analysis method,comprehensively and systematically reve al of pole vault techniques" human—pole" space-time cooperative rules and me chanisms and on the " human—pole" collaborative movement form put forwrd according to the views.Main conclusions are:1,The relationship between the state and performance of the technical act ions of the pole vault in the technical aspects of "human" and "pole" is interd ependence and mutual relation and interaction." human-pole" in the overall te chnical needs of the cooperative movement,and presents the characteristics of space and time collaboration,the synergistic effect is an important factor affect ing the performance of the project.2,according to the process of " human—pole" distribution of the system energy and change the rules of pole vault jump,pole vault is divided into the following three stages:stage energy,energy storage stage,the stage of releasing energy.The three stages for different purposes,so put forward specific requirements of the athlete's skill.High quality of pole vault techniques,should can fully reflect the characteristics of the " human—pole" cooperative motion of the and the technical movement can not only better exert the function of the human body ability,and can effectively use the superior performance of glass steel pole.3,The connotation of the theory and technology of pole vault,"people-pole"collaboration is in complete pole vault techniques in the process,and all the elements of the rod system is to obtain good effect,cooperate with each other in terms of time and space,mutual coordination of action and its mechanism of action.4,The world first-class male and female players H1 accounted for the highest point of the center of gravity of the body jumping ratio of 80.86%and 84.94%,H2 accounted for the highest point of the body center of gravity flight 16.52%and 14.47%,H3 accounted for the highest point of the body center of gravity flight 2.62%and 0.59%.That is one of the world's best players vault height still mainly rely on to hold pole height,a major force in promoting the pole rebound human "inverted hang"transition to "upside down" posture,not push from the height of the pole.5,the energy gain stage is designed to maximize the run-up speed of the human body,to obtain the larger base of energy,in our takeoff phase should reduce speed loss,to try to keep the corresponding kinetic energy reserves.T he collaborative " human—pole" mechanism mainly as follows:in to pole app roach links of course make full use of the front tension of the pole,to mainta in and play the run-up speed of the human body;in led the takeoff phase to the rational allocation of the take-off point,direction of take-off,take-off time,and pole against the temporal and spatial relationships among points time,to reduce the rate of loss,so as to follow-up technical points to lay a good foun dation.Empirical measurements of world class pole vaulter results show that t o link pole approach "to pursue the pole type" approach,led the takeoff phase of free takeoff technique in,can show remarkable effect of this stage of "peo ple-pole" cooperative movement.6,energy storage stage is to make full use of run-up and take-off of the kinetic energy,through the human body drape swing action body have as larg e as possible bending is obtained and stored elastic potential energy of the lar ge pole.The stage" human—pole" collaborative mechanism mainly as follows:increase the body's swing range and velocity of swing body,in order to incre ase the centrifugal effect of the pole,in order to better play the physical char acteristics of the glass steel pole "large amplitude bending".On world class po le vaulter empirical measurement results show that the "whiplash" swing techn ology can increase the amount of the pole rod bending,can more effectively u se the advantages of glass steel pole.7,energy release stage is to make full use of the pole to the storage of elastic energy make it into a human body gravity potential energy and kinetic energy.This stage " human—pole" collaborative mechanism mainly as follows:the regiment body stretching in time,direction,speed to rebound and pole act ively cooperate and coordinate movement,to take full advantage of the reboun d force of the pole to obtain as much as possible the jumping height.Empiric al measurements of world class pole vaulter results show that group and stretc hing from the "L" to "I" posture more fully,the more conducive to the huma n body to exercise.
