Study On The Influence Of High-intensity Functional Training On Executive Control Ability And Functional Exercise Ability Of College Students

Background: Previous studies have shown that people’s awareness of the benefits of exercise has gone through two general processes.From the early exercise to promote the exerciser’s physical quality and fitness level,improve the exercise ability and improve the physical state of the process.In 2008,after the publication of Professor John Reddy’s book "Exercise Changes the Brain",people realized that exercise can not only keep fit,but also strengthen the brain.Thus,the understanding of exercise changes the brain took a leap forward.Since then,the effect of exercise on brain cognition has attracted wide attention.Recently,high intensity functional training(HIFT),as an emerging exercise mode,has been favored by athletes because of its short time and quick effect.However,there is still no clear answer as to how high intensity functional training(HIFT)affects brain cognitive ability,especially executive control ability.Objective: This paper wants to test the effects of 6-week high-intensity functional training on executive control ability and functional motor ability of college students in Shandong Normal University,and to explore whether there is gender difference in the effects.The aim is to have a deeper understanding of the after-effect of high-intensity functional training,an emerging exercise mode,on exercisers and provide accurate reference for public fitness.Methods: 25 male volunteers and 27 female volunteers were randomly selected from Shandong Normal University.Parq&you questionnaire was used to screen the subjects who met the requirements of the experiment.The experiment was designed with longitudinal follow-up and control experiment.HIFT group was trained on rope,ladder,bounce,high leg lift,rope jump and fight ball,and RPE value was recorded after each training.3 days of training per week(according to the time of each subject,each training plan,but make sure that 3 times a week,the test leader is present during the training to ensure the training intensity and safety of subjects.The training will be postponed in case of the subject’s physical condition,such as the female menstrual cycle),and the training will last for 6 weeks.Before the start of the experiment,the indicators of the subjects were premeasured at 0 weeks,and then the data were collected every two weeks,and the indicators of 2 weeks of training,4weeks of training and 6 weeks of training were measured.Two weeks after the completion of training,the indicators of the subjects after the 2-week suspension were tested to observe the changes in the indicators of the subjects after the suspension of training.The control group did not participate in any form of training and maintained the normal life of the original schedule and rest system.The control group participated in the 0 week test,2 week test,4week test and 6 week test at the same time.No test was arranged for the control group in the8 th week(when the experimental group stopped training for 2 weeks).Results: The scores of the Montreal questionnaire showed a significant increase in the experimental group of male subjects at the second week of the test(P < 0.05),and after the sixth week.Compared with the control group,after six weeks of training and two weeks after suspension of training,there was a significant difference in the value added before training between men and women in the experimental group(P < 0.05),that is,the change of men was greater than that of women.In Stroop Color-word Test,the response time of male and female subjects decreased gradually and reached significant level at week 4(male)and week 6(female)respectively(P<0.05),There was no significant difference in Control Group(P0.05).There was a significant difference between the male experimental group and the Control Group in the shortening of the reaction time in the fourth and sixth weeks(P<0.05)In the experimental group,the ERP P300 response time of male and female subjects at Fz and Cz points showed a gradually decreasing trend.There was no significant difference between the two groups and between the two sexes(P> 0.05).At the Pz point,the ERP P300 response time showed a gradually decreasing trend.Males in the experimental group showed a significant decrease compared with the control group,from the second week(P < 0.05).There were significant differences in the change values between male and female in the fourth week and two weeks after suspension of training(P < 0.05).The decrease in ERP P300 was even greater in men.The total FMS scores of the experimental group showed a trend of gradual increase,and the total FMS scores of women in the experimental group showed significant differences in the fourth week and the sixth week respectively(P < 0.05).There was a significant difference between male and female in the experimental group(P < 0.05).FMSshoulder flexibility score of women in the experimental group increased,and the difference was significant at week 4 and week 6(P < 0.05).The fms-shoulder Joint Flexibility Score in the experimental group decreased significantly at the 4th and 6th Week(P<0.05).There was significant difference between the experimental group and the Second Week(P<0.05).The absolute value of VO2 Max,the relative value of body weight per kilogram and the relative value of body weight per kilogram of male and female subjects in the experimental group increased,but there was no significant difference between the group and the Group(P>0.05).There was no significant difference in the amplitude of P300 between the two groups at Cz(P>0.05).The changes of male and female athletes in the experimental group were significantly higher than that of male athletes at the 2nd week after training and after training suspension(P<0.05).There was no significant difference in pom-tmd scores between female and male subjects(P>0.05).There was significant difference between male and female in Control Group(P<0.05).Conclusion:⑴ High intensity functional training can effectively improve the executive control ability of college students.This is reflected in the increase of Montreal score,the decrease of Stroop Color-word Test response time and response time/accuracy,and the decrease of ERP-P300 response time and response time/accuracy at Cz and Pz points.(2)The effect of high-intensity functional training on executive brain control ability of college students showed certain gender differences.The change of Montreal score improvement was greater in men than in women,and the decrease of ERP-P300 response time and response time/accuracy in Pz point was greater in men than in women.(3)The mediating variable of the improvement of executive control ability by high intensity functional training might be the shortening of the latency period of ERP-P300.The findings do not support the cardiovascular fitness hypothesis.(4)High intensity functional training can significantly improve the functional sports ability of college students.This is reflected in an increase in the total FMS score.Especially over the hurdles,squats,torso stability push-up test and other movements score.(5)The influence of high intensity functional training on functional sports ability of college students shows certain gender differences.Reflected in the difference in the value of men and women,the increase of women is greater.In view of the safety,efficiency,high motivation,high persistence and other characteristics of high intensity functional training,combined with the results of this study,it is suggested that high intensity functional training can be used as one of the priority options for college students to strengthen the brain and physical exercise prescription.
