| 摘 要： | 目的:探讨不同负荷跑台运动对老龄雌性大鼠骨量及骨代谢相关指标的影响.方法:将40只12月龄雌性大鼠随机分为四组:对照组、低强度组、中强度组、高强度组每周6次共训练10周,观察不同强度运动对老龄雌性大鼠全身骨密度,股骨中点皮质骨密度、血清碱性磷酸酶(AKP)骨钙素(BGP)水平的影响.结果:低、中强度运动可使老龄雌性大鼠骨密度增加;三组均可使血清碱性磷酸酶(AKP)、血清骨钙素(BGP)水平升高.结论:低、中强度的跑台运动是一种适合于老年女性的健身方式,可以减缓伴随增龄而发生的骨量丢失,起到预防老年性骨质疏松的作用.

| Abstract: | Objective: to explore the effect of treadmill running different loads on bone mass and bone metabolism of old female rats.Methods: 40 12-month-old rats are randomly divided into 4 groups(n=10 respectively):control group,low-intensity exercise group,moderate-intensive exercise group and high-intensity exercise group.They are trained for six times per week for 10 weeks.We observe the effect of treadmill running of different loads on whole body bone mass density,bone mass of cortical bone in middle point of fe... |
