The Influence Of Moderate Intensity Exercise On The Male College Students’ Natural Killer Cells, Heat Shock Protein70under Acute Psychological Stress

Purpose:this study combined the current college physical education curriculum reform, through the way of exercise intervention, with acute psychological stress as intermediary variables, to discuss the influence of moderate intensity exercise on male college students natural killer cells and heat shock protein70under Acute Psychological Stress from the view point of psychoneuroimmunology, and try to establish the relevant theoretical model, provide relevant theoretical reference for college students to prevent, response and relieve stress, simultaneously to provide corresponding basis for the reform of school education.Methods:38male freshmen from public physical education classes of Yangzhou university were selected for the study, and divided into control group and experimental group. Then, the experimental group were intervented10weeks under a moderate intensity exercise. Combined with natural experiment, literature review, psychological measurement and mathematical statistics and so on methods to compare the experimental group with control group, and carries on the discussion.The results show that:(1) after acute stress before the trial test, the subjects before the overall state of mind is more acute psychological stress negative factor expression level increased;(2) before the test, the experimental group was negative mood state factor expression level is higher, after test, the experimental group and control group in mind level, there is no significant difference;(3) before the test, the experimental group and control group CD3-CD56+cells and molecules expression level there is no significant difference, the experimental group expression level is lower than the control group; When measuring the experimental group and control group after CD3-CD56+cells and molecules expression level exists significant differences, the expression level and the experimental group was higher than the control group;(4) measurement experimental group and control group before the heat shock protein70expression level, there is no significant difference of the experimental group expression level was higher than the control group; When measuring the experimental group and control group after heat shock protein70expression level exists significant differences, the expression level and the experimental group is lower than the control group; Research conclusions:(1) Trier social stress test play a good effect of acute psychological stress.(2) The result of Befindichkeitsskalen (BFS) shows that, the level of rivalry acute psychological stress of the male college students who intervented by a double times a week,10weeks of moderate-intensity exercise, has no significant difference compare with the male college students who do exercise once a week.(3) Through10weeks of moderate-intensity exercise intervention, the NK cell immune expression levels of the male college students who do exercises double times a week have been significantly improved comparing with the male college students who do exercise once a week after acute psychological stress, show that the double times a week, last10weeks of moderate-intensity exercise intervention improve immune function of the male college students.(4) Through10weeks of moderate-intensity exercise intervention, the HSP70expression of the male college students who do exercises double times a week have been significantly descended compare with the control group male students after acute psychological stress, it reflects that body’s that the male college students who do exercises double times a week, which last10weeks, improve the capabilities of male college students in rivalry acute psychological stress.
