ERP-based Cognitive Responses Of Rugby Players And Ordinary College Students In Different Emotional States

Objective of the study: Long-term sports training can improve athletes’ performance in specific sports.However,whether long-term training leads to differences in cognitive response processes between athletes and the general population needs to be further investigated.In this thesis,we want to experimentally determine how long-term exercise improves cognitive responses in different emotional states and how athletes differ from the general population in their cognitive responses.Research methods: EEG technology is a powerful tool for studying emotional and cognitive responses.event-related potential(ERP)is obtained by superimposing the EEG signals of related events,and it is an effective time-domain analysis method in EEG signal analysis,and relevant cognitive findings are obtained by peak and latency analysis of its waveform components.the P300 component is an actively evoked ERP component,relative to Its latency is related to the response time of the stimulus itself,and its energy distribution is also concentrated in certain specific brain regions,so it can be used for the study of cognitive responses.Based on this,in this paper,ERP components were collected by Biosemi EEG device,and rugby players of open sports and general college students were selected as the study subjects,and Oddball paradigm was used to study the cognitive responses of rugby players and general college students in different emotional The cognitive responses in different emotional states were studied.The P300 components were analyzed to obtain the correct cognitive response rate,reaction time and EEG component amplitude and latency of the two groups of subjects,and then to analyze their cognitive differences.Findings: 1.There was a significant difference in the correct response rates of rugby players compared to general college students in positive and negative emotional states,with rugby players having higher correct rates.2.There was no significant difference in the correct response rates of rugby players in all three emotional states;there was a significant difference in the correct response rates of general college students in both negative and neutral,negative and positive emotional states.3.There was a significant difference in the reaction times of rugby players compared to college students in all three emotional states,with rugby players using shorter reaction times.4.There was no significant difference in the reaction times of rugby players in all three emotional states;there was a significant difference in the reaction times of college students in negative and neutral,positive and neutral emotional states.5.There were significant differences in the amplitude of the P300 component in all three emotional states,with high amplitude in rugby players.6.In the comparison of topographic maps,rugby players activated a wider range of brain areas with greater intensity than the average college student.Conclusion: Rugby players’ reaction time and correct rate under different emotional states did not change much and were more stable;general college students’ reaction time and correct rate under different emotional states fluctuated significantly,indicating that long-term exercise helps individuals to improve their cognitive response ability under different emotional states.
