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。
Objective To observe the effect of early balance beam on psychological behavior in neonatal rats. Methods Thirty-two newborn rats were randomly divided into control group and exercise group. Exercise group for balance beam training for 4 weeks. The behavioral platform of animal behavior (open-field test) was used to measure the psychological behavior of neonatal rats aged 36-37 days. Results The activities in the center of the exercise group were shorter (1.441 ± 0.946) min than those in the control group (2.237 ± 0.724) min, with significant difference (t = 2.673, P <0.05); 2) (326.633 ± 106.218) cm in the control group (427.116 ± 102.185 cm), the difference was statistically significant (t = 2.727, P <0.05); 3) The activities in the surrounding area of the exercise group were longer (8.559 ± 0.946) 7.735 ± 0.721) min, the difference was statistically significant (t = 3.226, P <0.01); 4) There was more distance in the area around the exercise group (1 208.667 ± 176.794) cm than that in the control group (1062.900 ± 118.085) cm, Statistical significance (t = 2.721, P <0.05). Conclusion Early balance beam exercise can increase newborn cognition and emotional stability of the new environment.
