    Aim: Many studies have reported that aerobic exercise is effective in improving psychological well-being. However, there is little knowledge about whether it is effective at a low-frequency of one or two times aweek. The purpose of this study was to examine the effects of low-frequency aerobic exercise training on psychological well-being in young adults using a mental health questionnaire. Methods: University students who did not regularly exercise participated in the present study (training group: n=18, control group: n=16). The training group performed aerobic exercise training at a lowfrequency (total of 30 times, once a week or more), while the control group performed no exercise. Estimated V4O2max, body weight and psychological well-being were measured before and after the aerobic exercise training period. Results: V4O2max and body weight did not significantly change after aerobic exercise training. Compared with the control group, however, the training group exhibited a significant improvement in psychological well-being after the aerobic exercise training period. Conclusion: These findings suggest the possibility that even low-frequency aerobic exercise training is effective for improving psychological well-being.

    Previously, we reported the possibility that aerobic exercise training preserve the gray matter volume of anterior insular cortex( AIC) even in healthy young adult. Because aerobic exercise training simultaneously improved mental health, we hypothesized that psychological benefit of exercise was associated with AIC, which is considered to yield subjective feelings by integrating sensory input from the body. In the present study, we examined the correlation analysis between aerobic capacity and regional brain gray matter volume to examine the relationship between exercise and AIC. In addition, the relationship between gray matter volume of AIC and indices of mental health were also examined.  Right handed university students( 80 males and 21 females) were participated in the present study. After the acquisition of high resolution T1 MRI image, subjects completed self-reported questionnaires measuring mental health( generalized self-efficacy, self-acceptance, subjective happiness and development of identity). Then, V4O2max was estimated using an incremental submaximal exercise test on a cycle ergometer. The relationship between regional gray matter volume and V4O2max was analyzed using optimized voxelbased morphometry( VBM) technique. If the significantly correlated cluster was observed in AIC, the relationship between the cluster value and indices of mental health were examined.  The VBM analysis showed significant correlation between V4O2max and regional gray matter volume of left AIC( positive correlation) and striate cortex( negative correlation). The gray matter volume of left AIC was also correlated with indices of mental health( positive correlation with self-acceptance of physical area and subjective happiness).  The results of this study suggest that exercise influences the AIC structure, which may be associated with psychological benefit of exercise.
