Study On The Effect Of Biofeedback Relaxation Training On The Psychological Anxiety Of College Football Players

Football is a combination of techniques,tactics,psychology and other characteristics in one project.In football training,special training is important,but psychological training is more important.In the high-level competition,the psychological quality of the athletes plays a vital role in the victory of the whole match.Anxiety is an important index to measure the psychological state.Athletes’ anxiety will not only affect their physical health,but also affect their mental health and athletic performance.In the research of athletes’ anxiety,state anxiety and trait anxiety are the main typical manifestations.State anxiety refers to the emotion that athletes suddenly feel at a certain moment,while trait anxiety refers to the frequent emotional experience of athletes.If the two kinds of anxiety exceeds the critical value,they will have negative effects on the physical and mental health of the athletes and their sports performance.According to the inverted U-shaped theory,athletes’ competitive performance is closely related to their arousal level.If they want to give full play to their competitive state,they should adjust their arousal level.In football,it is best to maintain a medium arousal level.Excessive arousal level of players may lead to tension,anxiety and other negative emotions,which may lead to players’ unsatisfactory handling of some key balls,such as throwing the ball and going out of the field.At the same time,too low arousal level will also have adverse effects on athletes’ competitive state and physical and mental health.In this paper,by using multi-parameter biofeedback instrument to study the anxiety of the university football players,and USES the interview method,questionnaire survey method,experimental method and other methods were analyzed,and the biofeedback training as the main interventions designed to reduce the anxiety of athletes,the athletes in the anxiety situation of relaxation method,Learn to adjust their own anxiety state,so that it is maintained at an appropriate level.It is hoped that it can provide reference and basis for universities or clubs to carry out the psychological training of football players in the future.In this paper,16 football players in Jilin University were taken as the research samples.In order to accurately reflect the anxiety of the players,the author selected the shooting by the bar,passing the goal and chasing the goal as the test contents and gave out psychological scales to grasp the anxiety status of the players by issuing expert questionnaires.The EEG,EMG,skin electro G and skin temperature in biofeedback training were selected as monitoring indexes.The traditional group used the conventional psychological training method,namely the simulated game method,while the experimental group used the biofeedback training.It lasts for two months.There was no significant difference between the two groups before the experiment,but after different training methods intervention,there were significant differences in scores of football test and anxiety scale between the two groups.In the shooting through shot test,the mean and standard deviation of the experimental group were 1.000+0.031,and the mean and standard deviation of the traditional group were 0.534+0.188.The Sig value of the two groups was0.019,and the Sig value was < 0.05.In the registration test,the mean plus standard deviation of the experimental group was 4.500+0.925,and the mean plus standard deviation of the traditional group was 2.000+1.309.The Sig value of the two groups was 0.001,and the Sig value was < 0.05.In the chase goal test,the mean value and standard deviation of the experimental group were 0.750+0.163,and the mean value and standard deviation of the traditional group were 0.250+0.161.The Sig value of the two groups was 0.049,and the Sig value was < 0.05.The above test results showed significant differences.In terms of psychological scale scores,the two groups had significant differences in state anxiety and trait anxiety after the test.The mean plus standard deviation of state anxiety in the experimental group was38.125+1.642,and that in the traditional group was 41.375+2.722.SIG value of state anxiety in two groups was 0.012,SIG value was < 0.05.The mean plus standard deviation of trait anxiety in the experimental group was39.000+1.851,and that in the traditional group was 41.500+2.618.The Sig value of trait anxiety in the two groups was 0.045,and the Sig value was < 0.05.The mean plus standard deviation of Theta wave decreased from11.365+0.841 to 10.191+1.069 in the biofeedback training.The mean plus standard deviation of Alpha wave decreased from 6.823+0.432 before the experiment to 6.333+0.605.The mean plus standard deviation of Beta wave decreased from 6.795+0.409 to 6.445+0.629;The mean plus standard deviation of SMR wave decreased from 5.355+0.913 before the experiment to5.055+1.062,and the Sig values were all less than 0.05,showing a significant difference.After two months of anxiety intervention training for 16 college football players,the following conclusions were drawn:(1)the experimental group of biofeedback training method and the traditional group of simulation game method,can help reduce the anxiety of college students’ football player,but in a lower amplitude,application effect and scale,the performance of the experimental group is superior to the traditional group,shows that the intervention effect of biofeedback training intervention than game simulation method the effect is good.(2)through the contrast before and after the experiment,the experimental group of special test score better than traditional group test scores,and during the test,the experimental group showed the technology stability also is superior to the traditional group,biofeedback training that not only can affect college students’ football player’s emotional state,at the same time also to play to the technology and tactics with increasing the effect of the stability.(3)After the biofeedback training,SIG value of EEG,EMG,skin temperature and other indexes of the experimental group showed extremely significant changes,and it was also found that the decline of the EEG biofeedback index would significantly improve the value of the skin electricity index.The results indicated that EEG and EEG biofeedback indexes were more closely related in relaxation training.Therefore,biofeedback training with multiple parameters has a better effect on improving the anxiety of college football players.
