| Male trimple jump is that our country track and field events takes the lead in entering one of strong advanced world level item. The beginning of the sixties , our country Shandong athlete selected for a sports meet Tian Zhaozhong occupy the 2nd world that time as far back as right away with 16.58 ms achievement. The beginning of the eighties , Liaoning athlete selected for a sports meet Zou Zhen Xian gain a champion in eleventh the Universiade trimple jump competition in 1981 with 17.32 m , then, m gains the 2nd in third world cup track and field events with 17.34 , he takes a wound to have participated in the 23 Olympiad still winning the 4th in 1984. On eleventh Asia game, Fujian athlete selected for a sports meet Chen Yan Ping has jumped out of outstanding 17.51 ms achievement, has gained the hop step and jump champion. But, in recent years, the Chinese hop step and jump level great disparity compared with the world is very big. This status already arouses Angst of extensive track and field boundary colleagues. Until two young generals Li Yanxi , Gu Junjie successively jump out of 17.09 meters and 17.23 meters of outstanding achievement in 2004,have let everybody see Chinese male trimple jump future hope.Maximal level our country the main body of a book is being represented in order to participating in ten luck meetings in 2005 male trimple jump competition final former 8 athletes as studying the marriage partner , this eight people are fundamental is in at present being a project's turn. The closely related to motion achievement kinematics parameter looks on three as the content studying in springing , lead into upper limb moreover first the relevance kinematics parameter carries out priority studying. The parameter carries out kinematics analysis on technology of the analytical queen , the excellent athlete compares and with the world, explore our country male person hop step and jump athlete three spring to be hit by the rational and unreasonable factor , the exploration affirms that the impact of upper limb over achievement also admits of no doubt further except that lower limbs affects the achievement factor. And for this purpose suggest that build.Pass contrast studies find that, enter the competition time athlete selected for a sports meet pendulum adopting in springing in three arm posture is: The simple pendulum arm, lays bare an arm pair , lays bare an arm pair. The angle studies from biomechanics and the kinematics , this lays bare arm way according with that project characteristic, and the general trend is identical with excellent athlete of world. Explain that the coach and the athlete answer to come having already known to this one point, and having adopted by the training scientize corresponding measure in daily training middle. Some do not worth at the same time also but existence , do not embody in several aspect of the following mainly:One. Our country athlete mounts existence compared with excellent athlete of abroad in muscle density and the absolute strength gap. Reflect the Kelaituo exponent slanting small.Two. In the field of speed, our country athlete embodies out speed utilization ratio comparatively low , this is also to restrict one of the major factor that our country male person hop step and jump achievement improves.Three. Should reinforce upper limb strength aspect exercise, need to achieve oscillating extent is big , swing speed trains priority quickly quickly. Level speed provides a guarantee to fully utilizing.Four. The training in the field of end item strength remains to be improved in going a step further: Muscle kicks putting forth self's strength holding up to the leg part direction grasps inaccurate lead to start to prance an angle slanting big or slanting small; Prop up leg making a concession nature service ability difference leads to the angle slowing a knee down slanting small: Take off leg kick stretch a strength being not worth leading to taking off too, the leg knee-joint angle small , kicks to stretch lack in strength; Weak leg takes off kicking the ability range holding up waiting a minute.Five. Enter the competition time athlete selected for a sports meet proportion and rhythm being among springing spring to three in two palm charges the ability range, keeping having emphasized the distant degree that the first spring excessively, but having ignored queen double bounce level speed. If adopt "even style " or "leap-frogging technology "upper advantage of speed is kept arriving .That the athlete selected for a sports meet should reinforce training in the respect of having brought fairly good horizontal, but drawing in end item strength quality to make approach run of speed and so on into play out in competition though entering the competition time, wants to work at sth. with great care too in the field of end item technology , makes self technology action especially perfect thereby, be create much better achievement laying down firm foundation.
