目的观察早期空间爬行运动训练对子鼠心理行为的影响,为0~3岁婴幼儿运动方式促进心理行为发展提供理论依据。方法 25只新生鼠随机分为对照组(n=13)和运动组(n=12)。运动组进行早期空间运动训练4周。应用动物行为学平台(转棒仪和旷场试验)对36~37日龄子鼠进行心理行为测定。结果 1)运动组子鼠降落的潜伏期非常明显长于对照组(t=3.031,P<0.01);2)运动组子鼠跨格次数少于对照组(t=3.710,P<0.01);中心区域活动时间明显短于对照组(t=4.259,P<0.01);中心区域活动距离少于对照组(t=3.437,P<0.01);周边区域活动时间长于对照组(t=3.018,P<0.01);3)5min时间分段分析显示运动组子鼠中心区域活动距离少表现在首5 min,活动时间短表现在后5min。结论早期空间爬行运动可使子鼠对新环境认知能力增加、情绪稳定和运动协调性明显增加。
Objective To observe the effects of early space crawling training on the psychological behavior of the offspring rats and to provide a theoretical basis for the promotion of psychological behavior of infants and young children aged 0 ~ 3 years old. Methods Twenty-five newborn rats were randomly divided into control group (n = 13) and exercise group (n = 12). Exercise group for early space exercise training for 4 weeks. The animal behavioral platform (switch rod instrument and open field test) was used to conduct psychological behavior test on 36- to 37-day-old mice. The results showed that: 1) The incubation period of exercise group rats was significantly longer than that of the control group (t = 3.031, P <0.01); 2) (T = 4.259, P <0.01). The activities in the central area were less than those in the control group (t = 3.437, P <0.01), and the activities in the peripheral area were longer than those in the control group ); 3) 5min time segmentation analysis showed that the movement of rats in the center area of exercise less than the performance of the first 5 min, short activity time in the latter 5min. Conclusion Early space creeping exercise can increase the cognitive ability of the offspring to the new environment, with a marked increase in emotional stability and motor coordination.
