健常成人における有酸素運動プログラムの気分改善効果 The Effects of an Aerobic Exercise Program on the Mood in Normal Adults
Purpose : Evidences show that strong association between mood disorder such as depression and CAD prognosis. Also, physical exercise is known to improve the hostility in patients with coronary artery disease (CAD). However, little is known on the effects of physical exercise on the mood change in healthy adults with reference to gender difference. The purpose of our study is to examine how aerobic exercise affects mood states in normal subjects. Method : 62 healthy subjects (16 males, 46 females, the mean age + / -SD was 52+ / -14 with ages ranging from 20-72) were recruited by a local public relations magazine. The subjects participated in an aerobic exercise program twice a week for three months. We assessed the pre-and post-program mood with the Profile of Mood States (POMS) and classified the subjects into two groups by T-scores (the "relatively bad mood" group was defined by T score≦50 for "Vigor" and T score≧50 for other subscales). Results : The mood states seemed to improve after the aerobic program only in those with low T-score for Vigor and high T-score for other subscales of POMS. Decrease in T-score was observed in Depression-Dejection, Tension-Anxiety, Confusion and Fatigues, and Increase in T-score in Vigor were observed in female subjects. Changes in these parameters in male were also observed in a limited umber of subjects, which may not be enough to draw conclusive comments on the effect of the aerobic program for mood status in male subjects. Conclusion : Our three month-long aerobic exercise program improved the bad moods in healthy subjects. This effect might be useful for prevention against CAD.
