Nonlinear Dynamics Characteristics Analysis Of "Lunge" Action Coordination Of Epee Fencers

Epee Fencers need for good basic skills of action coordination. The important part of the coordination dynamics theory is the nonlinear dynamics characteristics, this view is that the movement of human behavior is a complex and open system of irreversible dissipative structure, the characteristics of the system is nonlinear, on the coordinated action of a particular variable value generated by a linear increase stability of a sudden another variable coordinated action of nonlinear response variation. In the national the coordination dynamics theory as a theoretical assumption so far has remained at the level of theoretical study. The most important validation of this study is the existence verification of the nonlinear dynamics characteristics in Epee Fencers "lunge" action coordination, and research the coordination model about the different level epee athletes based on this view. Through this experimental study, one can verify the theory of nonlinear dynamical assumptions, on the other hand, the theoretical can help the athletes and coaches to train and provide practical application of action coordination.This study's subjects are affiliated to 8 Epee Fencers of Shanghai Institute of Physical Education Competitive Sports School. This study uses two 2×3 with-subject designs. The first 2×3 within subjects experimental design is:2 players, ie, high and low; three kinds of situation, that is a fixed target scenario, barbed moving target situation and competition situations; the second test within 2×3 experimental design is as follows:2 players, ie, high and low; three kinds of speed, that is slower than usual training pace (slow average 1.15m/s), peacetime training speed (medium speed average 0.88m/s), as fast as the speed (fast average 0.70m/ s).Recording "lunge" action of each athlete through fixed situation, moving target situation of three speed and Competition situation,then analysis Epee Fencers "lunge" action of non-linear motor coordination kinetics in the Kinematics image.The main conclusions are as follows:(1)Under different speed requirements, Epee Fencers can to minimize the varia-bility of behavior characterized by the stability of the state and the most appropriate to reproduce the energy efficiency of state "lunge" action coordination mode.(2)Under different speed requirements, Epee Fencers' "lunge" action coordination with the control variable speed linear increase produced nonlinear variation, These findings with such people do Kelso finger movement, and the experiment task of individual who asked coordination model transformation of nonlinear gait classical experimental example are extremely behavior. It proved Epee Fencers' "lunge" action coordination of nonlinear dynamic existence.(3)Under different situations, Epee Fencers'have different stable "lunge" action coordination mode.(4)Under different situations, Epee Fencers' "lunge" action coordination with the control variable environmental complexity linear increase produced nonlinear variation. It may prove Epee Fencers' "lunge" action coordination of nonlinear dynamic existence.(5)Low-level and high-level Epee Fencers have resemble "lunge" action coordination model in training peacetime; High-level epee athletes' "lunge" action coordination to be significantly better than low-level'in the competition situation.
