摘要
研究目的:为探讨不同方式的运动对生长期大鼠长骨生长的影响,以为少年儿童的健骨方案提供理论参考。研究方法:将4周龄SD大鼠24只,根据体重随机搭配分成对照组、间歇运动组和持续运动组,每组8只,运动组分别进行为期9周的持续跑台运动和间歇跑台运动,测定血浆骨代谢指标和血浆GH、IGF-Ⅰ和E2及肝组织中IGF-Ⅰ的含量。研究结果:两运动组大鼠血浆ALP水平、肝脏IGF-Ⅰ水平均极显著高于对照组,间歇运动组和持续运动组的血浆IGF-Ⅰ水平分别极显著和非常显著地高于对照组,两组间无显著性差异。间歇运动组血浆GH和E2水平分别显著和非常显著性地高于对照组,并皆显著高于持续运动组。研究结论:9周间歇运动和持续运动运动皆可促进长骨的骨生成作用,提高肝组织中IGF-Ⅰ的生成和血浆IGF-Ⅰ的水平。间歇跑台运动对和青春生长发育相关的骨代谢系统调节因子的作用大于持续跑台运动。
To investigate the effects of different mode training on growing bone, 24 female SD rats （5 weeks old ） were randomly assigned to a prolonged running （PR, n=8）, an intermittent running （IR, n=8） and a control group （Con, n=8 ） respectively. During the 9 weeks training session, the run rats were trained at prolonged running, intermittent running on treadmill respectively. The result indicated that both of the running can significantly increase plasma ALP, IGF- I and hepatic IGF- I , further more, the intermittent running can also significantly increase plasma GH and E2, and the plasma GH and E2 levels of the intermittent running rats are all significantly higher than those of the prolonged running rats. The data suggested that both of the running can stimulate the rats＇ bone growth, and the effect of intermittent running on plasma hormones correlative to bone metabolism is stronger than that of prolonged running.
