The Short Jumping Athlete Jumps The High-jump Bar Practice Kinematics And Dynamics Research

Undeniably, short, jumps the project result level to enhance and the rapidly expand unceasingly, benefits in more and more modern science technology, in the sports train the application, benefits trains the theory in the sports to consummate unceasingly and to develop, benefits from the trainer and the athlete to the high jump project characteristic understanding unceasing deepening, thus improves and the consummation special training method as well as athlete's special technology unceasingly.The contribution which in this process, the sports scientific research to short, jumps the project result level's progress to play the role which and does is unwise to underestimate, the sports scientific researchers relied on the research results which each kind of modernized precise and advanced technology and the method obtained for athlete's training to provide the science reliable basis.Moreover the result level is higher, the science training's demand is also higher, is also bigger to its dependence.Therefore, must our country short, jump the project result level to push to again a new level, summarizes us to train the theory and the experience existing objectively, is further short to our country, jumping aspects and so on athlete's training process, training rule and characteristic conduct thoroughly, systematic, the comprehensive research, will be very important and essential.Jumps the high-jump bar practice is the typical high grade length practice way, it forces the muscle to elongate has the centrifugal contraction then to follow closely centripetal is contracting, subsequently achieves muscle's best contraction effect.Through summarizes various scholars to discover to the high grade long practice way research in that the majority experiments are devote in jump the deep practice research, to jumps the high-jump bar practice research, the author in the consult related literature and the books foundation had not discovered that conducts the research to it.Jumps the high-jump bar practice is one common lower limb explosive force training method, when the athlete carries on jumps the high-jump bar practices trains is only designs the high-jump bar according to many year training experiences highly with the spacing, lacks the science the theory basis, down to the practice effect is unsatisfactory, even cannot achieve jumps the high-jump bar practice desired effect.Therefore, this article from training angle embarking, with the aid of the movement training study, the sport biomechanics, statistics and so on related discipline theory to short, the jumping athlete jumps the high-jump bar practice effect to conduct the thorough research and the discussion, serves the purpose which serves for the training and the teaching.Thus it can be seen, this article in the basic strokes and the training method jump in the high-jump bar movement, carries on the elaboration from the kinematics and the power angle, has the application value very much.This article innovates the place to lie in the attempt using the phantom analysis, three dimensional to measure that kinematics and dynamics and so on strength method, through the control experiment condition, jumps a kind of movement to the dash and the caper athlete - - to jump the high-jump bar to practice to carry on the test, the exploration and the analysis different special athlete to jumps the influence which the high-jump bar movement structure produces, the goal is through to these factor analysis, to further promulgate the dash special and the caper special between relational aspect provides the preliminary scientific data and to jump the high-jump bar theory to lay the foundation, simultaneously provides the new mentality for the related movement training.The findings indicated:The strength - - time curve had reflected after the human body touches Taiwan, completes takes off in the entire process the ground reaction vertical lift component change characteristic, is reflects the human body muscle endogenic force the external performance.The overall looked that the caper athlete and sprinter's strength value displays the twin peaks the stability, was only displays the small difference in the cushion stage initial period strength value curve.In the total time, the sprinter is slightly shorter than the caper athlete, but the difference does not have the significance.Dash and caper athlete, in the zero-g period, the cushion stage and the pedal extend the stage in the time not to have the significance difference, but in soared the stage actually to display the significance difference, created this kind of difference the primary cause is because two kind of athletes formed the respective movement technology in the long-term movement training to finalize to cause.The dash and the caper athlete various joints' angle in both feet Taiwan instantaneous, the most biggest cushion stage as well as in the cushion scope does not have the significance difference; Explanation sprinter and caper athlete when the transmission cushion, the pedal extend produces the strength more or less the same, in the cushion effect as well as to takes off the effect influence photograph well to be consistent, meanwhile may the objective reflection the two's collapsibility working ability have the similarity.May see from the data analysis, the caper athlete leaps compared to the sprinter center of gravity highly high, and the difference has the significance, explained the caper athlete lower limb muscle supplies the efficiency, lower limb's eruption strength as well as the pedal extend the effect is friends with in the sprinter, simultaneously reflected the caper athlete in takes off in the process the double arm's arc of oscillation to be friends with in the sprinter.After on the other hand may the indirect reflection release the impulse as well as the pedal extend stage factor and so on center of gravity speed differences.May see from the sprinter and the caper athlete's dynamics parameter, sprinter and caper athlete, in the both feet Taiwan instantaneous strength value, the biggest cushion time's strength value and the pedal extend the stage in the value not to have the significance difference most vigorously, but was displaying the remarkable difference after in the both feet Taiwan's relative impulse extreme value, this was mainly because the caper athlete in the vertical upward movement's acceleration, various links movement's coordination and the lower limb muscle's active efficiency was friends with in the sprinter causes, meanwhile objective reflection caper athlete's lower limb muscular strength well in sprinter.Sprinter to Taiwan instantaneous center of gravity speed compared to caper athlete's small, and the difference has the significance, explained that the caper athlete's final pedal extends the effect to be friends with in the sprinter, after simultaneously takes off the center of gravity most to be higher than the sprinter greatly highly.
