Abstract

Epee Fencers need a good foundation of skills motor coordination. Nonlinear dynamics as the focus of one of the important theory of motor coordination, coordination of power theory point of view, this view is that the movement behavior of the human body is a complex open irreversible dissipative structure system, the characteristics of the system is nonlinear, nonlinear variation of a sudden another coordinated action value of the variable response in some specific coordinated action variable value stable linear increase. Assumption so far is still stuck at the level of theoretical discussion, the most important purpose of this experimental study is to verify Epee Fencers lunge stab motor coordination nonlinearity in the nonlinear dynamics of domestic coordination of power theory as a theory The kinetic characteristics of existence, and Epee Fencers coordination model based on this view of the differences. Through the experimental studies, on the one hand to provide empirical support for the concept of the theory of nonlinear dynamical assumptions, On the other hand, for the athletes and coaches how to train and provide a theoretical basis for the practical application of motor coordination. The subjects of the experimental study for eight of the Shanghai Institute of Physical Education subsidiary of competitive sports school Epee Fencers. This experimental study using two 2 × 3 is within experimental design, Cap a 2 × 3 trial within the experimental design: two athletes level, i.e. a high level and a low level; three scenarios, i.e. the fixed target scenario, gill movement target scenarios and game scenarios; second 2 × 3 trial within experimental design: the 2 athlete level that is high-level and low-level; 3 speeds slower speed than usual training speed (slow average of 1.15 m / s), and the peacetime training speed (medium speed average of 0.88m / s), as fast as possible (rapid mean to 0.70m / s). Nonlinear coordinated by videotaping each athlete fixed target situation and moving target scenarios under three speed and game scenarios lunge stab \dynamic characteristics. The study reached the following main results and conclusions: (1) different speed requirements, Epee Fencers able variability with minimal behavior characteristics of steady state and optimum energy efficiency status to reproduction the \(2) different speed requirements, epee athletes P2 elbow, knee same phase movement relative time, this logo stability \finger movement task experimental nonlinear changes in the results of these findings with Kelso people do, and Shapiro et al do individual gait coordination paradigm shift in the nonlinear behavior of classic experimental illustrations are very similar. Epee Fencers the \(3) epee athletes with certain conditions characterized in some scenarios, it will be out of this now specific limb movement coordination mode of self-organization, epee athletes in different contexts different stable lunge stab \motor coordination mode. (4) different contexts, Epee Fencers P2 elbow, knee same phase movement relative time the logo and stability the \linear increase resulting in a linear change. Therefore, to prove Epee Fencers the \(5) low-level epee athletes and the high level epee sports op members in peacetime training \to be significantly better than low epee athletes.
