스포츠 생리학 : 운동부하별 인지적, 신체적 스트레스가 β-endorphin, Norepinephrine, IgA, IgM 반응에 미치는 영향 = The Effect of Cognitive Stress and Exercise Intensity on β-endorphin, Norepinephrine, IgA, and IgM

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the changes of profile of mood states(POMS), rate of perceived exertion(RPE), norepinephrine(NE), β-endorphine(β-EN), immuno-globulin(Ig) M, and IgA according to high and moderate intensity exercise after rebuke on evaluation of learning task for cognitive stress. Subjects were male physical education major male students in H university. The subjects divided into four groups; stress treatment+high exercise(S+H), high exercise(H), stress treatment+moderate exercise(S+M), and moderate intensity exercise(M). The subjects in high intensity exercise group were run for 25min on treadmill at 85-90% of HRmax and the subjects in moderate intensity exercise group were urn for 45min on treadmill at 65-70% of HRmax. The HR was recorded by PE-3000 with 30sec interval. Blood samples were taken from antecubital vein at pre-, post-0, post-30min of treatment. Data were analyzed with t-test and MANOVA of SPSS. The results were summarized as follows:
1. The changes of POMS and RPE were signiftcantly increased in cognitive stress treatment group than the control group.
2. The changes of NE and β-EN were significantly different among groups. Namely, the changes of NE in the group SH were significantly different from the group H, M, and MS, but the changes of β-EN were significantly different only within exercise intensity groups.
3. The changes of IgM were significantly different, but IgA did not show any significant difference between groups.
In conclusion, the inspectation of POMS and RPE verify that the rebuke on evaluation of learning task has the validity of cognitive stress model in this study. Both of high intensity exercise and cognitive stress effect harmfully on mood, endocrine, and immune system.
