Abstract: Objective To observe the balance beam exercise on psychological behavior of neonatal rats. Methods A total of 32 newborn rats were randomly divided into control group (n=16) and exercise group (n=16).The neonatal rats of the exercise group were trained by balancing for four weeks.And the rats of 36~37 day-old underwent a psychological behavior measurement by animal behaviour platform (open-field test). Results 1) The time of acting in the central area of exercise group [(1.441±0.946) min] was shorter than that of control group [(2.237±0.724) min,t=2.673,P<0.05].2)The distance of acting in the central area of exercise group [(326.633±106.218) cm] was less than that of control group [(427.116±102.185) cm,t=2.727,P<0.05].3) The time of acting in the surrounding area of exercise group [(8.559±0.946) min] was longer than that of control group [(7.735±0.721) min,t=3.226,P<0.01].4)The distance of acting in the surrounding area of exercise group [(1 208.667±176.794) cm] was longer than that of control group [(1 062.900±118.085) cm,t=2.721,P<0.05]. Conclusions Early balance beam exercise increase rats' cognitive ability and emotional stability in the new environment.

摘要: 目的 观察早期平衡木运动对新生鼠心理行为的影响。方法 32只新生鼠随机分为对照组和运动组各16只。运动组进行平衡木运动训练4周。应用动物行为学平台(旷场试验)对36~37日龄新生鼠进行心理行为测定。结果 1)运动组中心区域活动时间短(1.441±0.946)min,对照组(2.237±0.724)min,差异有统计学意义(t=2.673,P<0.05);2)运动组中心区域活动距离少(326.633±106.218)cm,对照组(427.116±102.185)cm,差异有统计学意义(t=2.727,P<0.05);3)运动组周围区域活动时间长(8.559±0.946)min,对照组(7.735±0.721)min,差异有统计学意义(t=3.226,P<0.01);4)运动组周围区域活动距离多(1 208.667±176.794)cm,对照组(1 062.900±118.085)cm,差异有统计学意义(t=2.721,P<0.05)。结论 早期平衡木运动可增加新生鼠对新环境认知能力和情绪稳定性。
