[Abstract]:Objective: in competitive sports, sports mental fatigue will lead to poor performance of athletes in training and competition, and even serious mental health problems.In this paper, the neurotransmitter mechanism of central fatigue induced by long time cognitive processing tasks is explored through experiments based on the brain wave ultralow fluctuation technique.Methods: using Flanker task participation as independent variable, behavioral data and heart rate variability data as dependent variables.A pre-test and post-test study was conducted in 38 undergraduate students of physical education college of Ningbo University. The behavioral data and heart rate variability index were used to detect whether cognitive task participation could induce central fatigue and S-pedigree changes.Results: (1) the accuracy and reaction time of different time periods showed a decreasing trend and there were significant differences (p0.01) the total standard deviation of heart rate variability (HRV) before and after the experiment and the significant increase reflecting the fast-changing components (P0.01 + p0.01P0.01TY3) the power value of high frequency band decreased significantly (P < 0.01 or P < 0.05 or P < 0.01, P > 0.05, respectively.) the total standard deviation of heart rate variability (HRV) was significantly increased before and after the experiment.P0. 05, low frequency power,There is no significant difference between the power values of low frequency band and high frequency band. (p0.05P0. 05) the S4 strain representing serotonin has a significant rise (p0. 01), while other inhibitory neurotransmitters have no significant difference (p 0. 05%). The S6 strain with strong excitatory transmitters has a significant decrease in p0. 01, while the other S6 strains with strong excitatory transmitters have a significant decrease in p0. 01, while there is no significant difference in other inhibitory neurotransmitters (p 0. 05).There was no significant difference in perphentive neurotransmitters (p 0.05).The conclusion of the study is that: 1, long time cognitive task can cause the decrease of correct rate, the shortening of reaction time and the decrease of the vagus component of HRV by 2%, and the long time cognitive task can cause the increase of S4 significantly.It is suggested that S4 is a sensitive index for evaluating cognitive central fatigue, and long term cognitive task can not induce the increase of other inhibitory transmitters and the decrease of excitatory transmitters.
