Abstract: In order to probe into the effects of restrained stress on monoamine neurotransmitters and behaviors of mice as well as aerobic exercise intervention effects, the authors selected 80 1-month old C57BL/6 mice, randomly divided them into 4 groups: a control group (Control, n=20), a restrained stress group (Stress, n=20), an exercise group (Ex, n=20) and an exercise + restrained stress group (Stress + Ex, n=20), fed the control group in a calm con-dition, let the restrained stress group suffer restrained stress for 2 weeks, let the exercise group exercise on a tread-mill 2 hours a day, let the exercise + restrained stress group suffer restrained stress and exercise on a treadmill si-multaneously, and revealed the following findings: in the behavior experiment, the mice in the restrained stress group had significantly decreased social behaviors and significantly increased levels of anxiety and depression be-haviors (P<0.05), while exercise intervention could alleviate the effects of restrained stress on these behaviors. Bio-chemical indexes indicated as well that aerobic exercise effectively alleviated retrained stress induced changes of behaviors and monoamine neurotransmitters. Conclusion: restrained stress will cause changes of social communica-tion and emotion related behaviors, while exercise intervention will play an effective role of alleviation.
