Abstract：With the experimental objects of Shanghai 22 fleuret athletes, adopted by the study pattern of expert-novice, using the methods of the synchronous recording technique of eye-movement with event-related brain potential, this paper studied the characteristics and the neur-mechanisms of identifying motor skill, in order to provide the theoretical and methodology for scientifically training fencer athletes. The results were as followed: During the process of identifying motor skill, the time of the first fixation point, the second fixation point, the first eye saccade and the average time of the eye saccade, fixation and the total fixation time of high-class fleuret athletes were all shorter than that of low-class fleuret athletes. Moreover, the peak amplitude of P1, N2 of high-class fleuret athletes were lower than that of low-class fleuret athletes; the peak latency of N2, P3 of high-class fleuret athletes were shorter than that of low-class fleuret athletes on the relevant brain cortex. The results indicate that the process of identifying skills of high-class fleuret athletes is not only fast but also economic. The neur-mechanisms may be the movement level of brain nerve of P1, N1 and N2 induced on the special brain cortex are lower, the time of N2 and P3 induced are early.
