    摘要:

    目的 探讨不同运动方式干预对攻击行为大鼠情绪行为的影响。 方法 12 周龄 SPF 级雄性 SD 大 鼠 50 只,适应性饲养一周后随机分为 5 组:安静(A)组、攻击模型(G)组、攻击跳台(GT)组、攻击跑台(GP)组、入侵(R)组。采用单笼饲养+外来鼠入侵建立大鼠攻击模型,观察攻击模型大鼠情绪行为的变化。采用跳台运动和 跑台运动两种运动方式干预 8 周,跳台组每周训练 3 d,跑台组每周训练 5 d,在训练中期和训练后期对各组大鼠进 行旷场实验,观察运动干预后大鼠情绪行为的变化。 结果 在实验过程中,攻击模型(G)组大鼠探究行为、活跃程度和自主活动度均显著性降低,情绪焦虑、紧张度较高。 跳台运动和跑台运动干预 4 周后,攻击跳台(GT)组和攻击跑台(GP)组在站立次数、跨格数和修饰次数均有显著性差异,两组大鼠的平均速度、中央活动时间及总路程极 显著增加,两种运动对攻击模型(G)组大鼠兴奋性、探究行为和对自身关注度等行为变化均有不同程度的提高,而 且跳台运动对大鼠行为的影响程度更明显。跳台运动和跑台运动干预 8 周后,攻击跳台(GT)组和攻击跑台(GP) 组大鼠的兴奋性极显著性提高,但是跑台运动干预后的大鼠兴奋性、探究行为及自发活动显著性降低,与攻击模型 (G)组无显著性差异。 结论 进行适宜的跳台运动和跑台运动对攻击行为大鼠的焦虑、紧张情绪和动作行为有明显改善。

    Abstract:

    Objective To investigate the effects of different types of exercise on emotion and behavior in aggressive rats. Methods Fifty-six 12-week-old SPF male SD rats were randomly divided into the following five groups after 1 week of adaptive feeding: quiet ( A), aggressive model ( G), aggressive jumping ( GT), aggressive treadmill (GP), and aggressive (R). Rats were fed in single cages, subjected to invasion by foreign rat to establish the aggressive model, and observed for changes in emotional and behavior. Interventions with jumping and treadmill exercises for 8 weeks the aggressive jumping were training for 3 days a week, and the treadmill were training for 5 days a week. in the middle and late stage of training, the open-field experiments were conducted to observe changes in emotion and behavior after exercise intervention. Results The exploratory behaviors, degrees of activity and autonomous activity of the rats in the aggressive model (G) group were significantly reduced, the anxious mood and tension were higher. After 4 weeks of jumping and treadmill exercise intervention, there were significant differences in the number of upright times, crossing numbers, washing and shaving times between the aggressive jumping (GT) and the aggressive treadmill (GP) groups. The average speed, central activity time and total distance of the two groups of rats were significantly increased. The excitability and exploration effects of the two kinds of exercises on the aggressive model (G) group were significant, and the influence of the jumping exercise on rat behavior was more obvious. After 8 weeks of jumping and treadmill exercise intervention, the excitability of rats in the aggressive jumping (GT) and aggressive treadmill (GP) groups increased significantly, but the excitability, exploratory behavior and spontaneous activity of rats following the treadmill exercise intervention decreased significantly, and there was no significant difference with the aggressive model (G) group. Conclusions Proper jumping and treadmill exercise significantly improved the anxiety, nervousness and proactive behavior of the aggressive rats.
