Abstract: Objective To explore the effect of sports training on premature animal by intrauterine infection caused. Method sThe preterm animal model was made by injection the lipopolysaccharide in the pregnant mice.Premature animal were randomly divided into two groups:the physical training intervention group,the model group,without premature rats birth from the normal pregnant rats were as control group.After 7 days,all young rats born of intervention group were different to the corresponding acupuncture and exercise training,At 28 days of age,the results of open field test and rotarod test of were recorded and analyzed. Results Physical training could significantly improve the premature animal athleticism and exploratory behavior,the difference was statistically significant (P<0.05). Conclusion Early physical training can obviously improve the premature animal's athleticism and exploratory behavior abilities.

摘要： 目的 探讨早期运动训练对宫内感染所致早产幼鼠运动行为的影响。方法 对孕鼠腹腔注射脂多糖以制备早产幼鼠模型,将早产幼鼠随机分为2组:运动训练组及造模组,将为未造模组孕鼠所产无早产的正常幼鼠设为对照组。出生第7天后对不同干预组幼鼠予相应的针刺及运动训练,28 日龄对各组仔鼠进行旷场实验及转棒实验测试,记录各项测试结果,进行统计分析。结果 运动训练可明显改善早产大鼠运动及探索行为能力,且运动干预后与造模组早产幼鼠的运动行为能力之间的差异有统计学意义(P<0.05)。结论 早期运动训练可明显改善早产幼鼠运动及探索行为能力。
