[Abstract]:Research purpose: attention is an important prerequisite for athletes to master skills. In the process of competition or training, the athletes' judgment of the field environment and the mastery of sports skills can not be ignored. The attention characteristics of different sports athletes have certain differences. This study is to observe the athletes' attention by observing Wushu routines and Wushu Sanda projects. Characteristics and the changes of ERP, in order to further reveal the intrinsic neural mechanism of the characteristics of Wushu athletes, and then provide scientific basis for the selection of Wushu athletes and the scientific training of Wushu. Research objects and methods are divided into three groups: the Wushu Routine Athletes of Shanghai Institute of Physical Education (38 people), Wushu Sanda Athletes (37 people) and non sports ordinary college students (27). The athletes are required to have more than five years of martial arts training years and more than two levels of sports; ordinary college students are required to have no sports level certificate of sports level, and do not participate in systematic exercise training. The study is divided into three parts: the first part, the unified fill. Write attention measurement scale: attention span, attention to stability, attention transfer and attention distribution; the second part: through the E-Prime program, conduct behavior measurement experiments, the index is the reaction time and the error rate; the third part: through the E-Prime program and the EEG acquisition system, the ERP experiment, the index for the response, positive error rate, amplitude and potential The results of the study: 1. there was no significant difference between the three groups of attention characteristics between the attention span and the attention stability two indexes; attention transfer had significant difference (P0.05); attention allocation was very significant difference (P0.01); attention allocation was significant difference (P0.05) in the Sanda group and the set group, and the Sanda group and the control group were very significant. The difference (P0.01), the group and the control group were significantly different (P0.01).2. selective attention behavior test results (1) endogenous attention behavior characteristics of three groups of subjects under the effective stimulus conditions were better than the invalid stimulus, but the difference was not significant (P0.05). Under the effective stimulus conditions, the three groups of reaction time There were significant differences (P0.05). The specific performance was that the Sanda group was superior to the control group (P0.01); the routine group was superior to the control group and had a very significant difference (P0.01); the routine group was superior to the Sanda group, but the difference was not significant (P0.05). The three groups had very significant differences (P0.01) under the conditions of non effective stimulation (P0.01). The body performance was as follows: the Sanda group was superior to the control group (P0.01); the routine group was superior to the control group (P0.01), and the Sanda group was superior to the routine group, but the difference was not significant (P0.05). The reaction speed of the three groups was accelerated with the extension of SOA, and there was a significant difference (P0.05) when SOA was 500ms. The reaction speed of the group was the fastest, followed by the Sanda group, and the control group had the slowest reaction speed. (2) the response speed of the three groups was better than that of the invalid stimulus, but the difference was not significant (P0.05). The response of the three groups had significant difference (P0.05) under the effective stimulus. The body performance was as follows: the Sanda group was superior to the control group (P0.01); the routine group was superior to the control group and had a very significant difference (P0.01); the Sanda group was superior to the routine group, but the difference was not significant (P0.05). The response of the three groups was very significant (P0.01) under the condition of ineffective stimulation (P0.01), and the specific performance was that the Sanda group was superior to that of the Sanda group. The control group had a very significant difference (P0.01); the routine group was superior to the control group (P0.01), and the Sanda group was better than the routine group, but the difference was not significant (P0.05). Each group had a inhibition effect when SOA was 300ms, and the reaction speed was slower than the other conditions. Then the reaction speed of each group was accelerated with the prolongation of SOA. When SOA was 800ms, there was a significant difference (P0.05). The reaction rate of the Sanda group was the fastest, followed by the routine group. The ERP change group and the routine group of the control group, which had the slowest reaction speed,.3. selective attention, induced the N1 components in the parietal lobe and the top and top occipital leaves in the ERP experiment. The control group failed to induce the N1 component, but in the parietal lobe. And the top occipital leaf induced more obvious N2 components, PZ, P2, P7, P8, POz, PO4, PO7 and other electrodes showed significant difference in the main effect and the time main effect. After the superposition of the waveform, the N2 wave amplitude induced by the Sanda group was obviously higher than that of the control group and the routine group. 1. There are some craftsmanship and perennial martial arts training can improve the attention distribution and attention transfer ability of the athletes' attention characteristic to a certain extent, but there is no obvious influence on the attention stability and attention span. The information processing and search strategies of the.2. Wushu Sanda Athletes' selective attention are superior to the routine group and the control group. Under the condition of ineffective stimulation, the Sanda athletes can quickly mobilize more attention resources, the speed of visual attention is faster, the.3. Sanda athletes and the routines can induce more obvious N2 components under the exogenous attention search paradigm, and the N2 components induced by SOA as 500ms and 800ms are particularly significant.
