| Objective:Brain execution control is the core component of the brain is cognitive functions, including the execution control to remove excess irrelevant information, automatic suppression response, coordination of cognitive processes, optimization of reaction mode, to ensure the correct completion of cognitive tasks, to achieve the established goals. Core executive control of the reaction inhibition (attention and inhibition) and monitoring, that is, handling and processing of information processing ability to distinguish between useful information and useless information, that conflict control. Wherein the reaction is suppressed to prevent an upcoming stimulus and automatic response information note two aspects;and monitor is to check on memory contents and updates. Including two executive control system, a system to assess the implementation of the monitoring function, a system to regulate the completion of the reaction inhibition.P300 refers to 300ms-800ms after receiving stimulation while the forward wave. P300 amplitude refers to how much in an interview with a certain kind of stimulation to stimulate the brain assigned to the attention of the resources. P300 incubation period refers to the brain stimulation began to accept the stimuli used in the reaction time of the speed. P300 corresponds to a conflict control theory conditioning system, reflecting the execution control response inhibition. Many studies show that the degree of precision of different sports, different effects on cognitive function of the brain. Athletics, Martial Arts Sports, Martial Arts, Dance body movement as different forms of movement, degree of motion tasks of different complexity, and therefore different inputs of physical resources, spiritual resources, caused by the effect should also be different. Different forms of exercise sports have a certain fitness function, but studies on a variety of different sports on the brain cognitive function in the country is less,the study of cognitive potentials P300 see even more rare. According to the special student college entrance examination, and selected Shandong University Changqing Campus Lake Track and Field?Sports Institute of Physical Education Department, the Department of National Traditional Sports Martial Arts, Wushu, sophomore boys Arts Physical Education Department of Sports Dance classes for subjects using methods twenty-two comparison tests, lateral compare the effects of different sports on event-related potentials P300 and evaluate the different forms of exercise sports different on brain cognitive function in effect, in order to be able to enrich knowledge in the field and fitness sports motion prescription provide experimental evidence.Subjects and Methods:recruitment propaganda,using selected demographic characteristics Changqing, Shandong Normal University Lake Campus Physical Institute of Physical Education Department of Track and Field, National Traditional Sports Department Martial Arts, Martial Arts, Arts Physical Education Department of Sports Dance classes sophomore boys 54 people, informed consent. Wherein Athletics group(n=16),Sanda group (n= 14), the routine group(n=17), sports dance group(n=7) Study of literature, mathematical statistics and experimental method or the like. Experimental tests were completed in Changqing, Shandong Normal University Lake Campus Human Movement Science Laboratory. The subject does not perform any exercise, according to the original living habits.A one-time recording and analyzing the subject of P300 index. Event-related potential tests by the German Brain Products GmbH stockdorfer straBe 54D-81475 Munich produced Brain Vision Analyzer instrument. Using SPSS 17.0 for windows was used for descriptive statistics and inferential statistical difference between the groups was significant testing by independent sample T test, the difference was significant criteria used P<0.05, significant difference between the standards adopted P<0.001, the results were in order to represent.Results:(1) when the correct response Sanda group and member of the dance group was significantly shorter in track and field group (P<0.05); the correct operating rate among the four groups showed no significant difference (p>0.05). It shows the reaction Sanda and body dance group faster than athletics group.(2) the relative value of maximal oxygen uptake between the subject and the absolute value of the four groups showed no significant difference (p>0.05); Routine grip group was significantly lower than the other three groups (p<0.05). Display four groups grip lowest routine group.(3) stimulation paradigm in the S1 (>>>>>), S2 stimulation paradigm (<<<<), S3 stimulation paradigm (<<> <<), S4 stimulation paradigm (>> <>>) under four there are some differences in P300 amplitude and latency between the groups, the latency difference is more obvious (amplitude, S1,12; S2,12; S3,7; S4,3/latency, S1,23; S2,22; S3,27; S4,14), but each of the electrodes on the scalp distribution points were mixed, P300 amplitude differences between the four groups are distributed in Fc5, C3, Cpl, Cz points, while the P300 latency differences among the four groups are distributed in Fz, Fpl, Cp5, Pz, Oz, P4, P8, P7, Cp6, Fp2 points.(4) four groups P300 latency difference was the most widely used is the body of track and field and dance group group, dance group performance up to body latency. P300 amplitude difference among the four groups of the body was the most widely used is the dance group and routine group, showed the largest P300 amplitude body dance group, Sanda body dance group and similar groups. Whether P300 P300 amplitude or latency, between the track and field group and routine group was minimal.Conclusion:Athletics, Sanda, Wushu, sports dance movement as different forms of movement, on P300 to have some differences, show some selectivity for its existence affect the results, such as indicators and P300 scalp lead distribution. |
