　　Objective: To study the effects of various exercise interventions on the emotional behavior of aggressive rats.

　　Methods: 5012-week-old SPF male SD rats were randomly divided into 5 groups after 1 week of adaptive feeding: quiet (A) group, attack model (G) group, attack jumping platform; in (GT) group, attack In the treadmill (GP) group and the invasion (R) group, single cage breeding + foreign mouse invasion was used to establish a rat attack model. We observed changes in the emotional behavior of the aggression model rats.

　　The two exercise methods are: group 3 days a week, treadmill group 5 days a week, and each group of rats in the middle and late training period to conduct field experiments to observe the changes. Changes of emotional behavior in rats after exercise intervention. Results During the experiment, the rats in the aggressive model (G) group significantly reduced exploratory behavior, activity levels and spontaneous activities, and increased emotional anxiety and tension. After four weeks of intervention on the platform and treadmill, there were significant differences in the number of standings, strides and changes between the platform jumping (GT) group and the treadmill (GP) group they attacked. Both groups of rats increased significantly. The excitability, exploratory behavior and self-attention of the rats in the aggressive model (G) group were improved to varying degrees. The platform jumped after 8 weeks of platform jumping and treadmill exercise intervention and attack platform (GT). The irritation of rats in the group and the aggressive treadmill (GP) group was significantly increased after stimulating, exploratory behavior and spontaneous treadmill exercise intervention, but different from aggression, it was significantly reduced. There was no significant difference in the model (G) group.

　　Conclusion: Appropriate platform jumping and treadmill exercise can significantly improve the anxiety, tension and behavior of rats with aggressive behavior.
