文题释义:
骨密度:①全称是骨骼矿物质密度,是骨骼强度的一个重要指标,以g/cm2表示,是一个绝对值。在临床使用骨密度值时由于不同的骨密度检测仪的绝对值不同,通常使用T值判断骨密度是否正常。T值是一个相对值,正常参考值在-1和+1之间,当T值低于-2.5时为不正常;②骨密度是骨质量的一个重要标志,反映骨质疏松程度,是预测骨折危险性的重要依据。由于测量仪器的日益改进和先进软件的开发,使该方法可用于不同部位,测量精度显著提高。除可诊断骨质疏松症之外,尚可用于临床药效观察和流行病学调查,在预测骨质疏松性骨折方面有显著的优越性。
年龄段:联合国世界卫生组织对全球人体素质和平均寿命进行测定,将人的一生分为5个年龄段。44岁以下为青年人;45-59岁为中年人;60-74岁的为年轻老年人;75-89岁的为老年人;90岁以上为长寿老年人。这5个年龄段的划分,将人类的衰老期在旧标准的基础上推迟了10年,这对人们的心理健康和抗衰老意志将产生积极的影响。
摘要
背景:
目前研究表明虽然不同类型的运动对骨密度的影响程度不同,但是在运动能够提高骨密度这一问题上已经达成共识。
目的:探讨排球运动对女性骨密度的影响以及女性骨密度的年龄和侧别差异。
方法:受试者共计112人,分为青年实验组20人,青年对照组20人,中年实验组20人,中年对照组18人,老年实验组18人,老年对照组16人。实验组是来自于高校的排球教师或长期坚持排球运动的女教师。对照组也是高校女教师,但是几乎没接触过排球运动。采用美国GE公司生产的Prodigy Advance型双能X射线骨密度仪对受试者的左右桡骨远端1/3处和腰椎(L2-L4)的骨密度进行骨密度测定。利用SPSS20.0数据统计软件对所得数据进行Independent-Sample T Test和one-way ANOVA。
结果与结论:①桡骨骨密度在相同年龄段实验组均显著高于对照组(P < 0.05),青年实验组显著高于青年对照组(P < 0.05);②老年段腰椎(L2-L4)骨密度实验组显著高于对照组(P < 0.05);③各观察指标在老年组和其他两组之间差异均有显著性意义(P < 0.05);④结果说明,排球运动对女性桡骨和腰椎骨密度都有良好的作用,尤其是右侧桡骨;该运动对青年女性两侧桡骨骨密度的影响具有不对称性,这可能与两侧手臂所受的运动负荷不同有关;排球运动能够有效延缓老年人骨量的丢失。

Abstract:

BACKGROUND: It has been shown that different types of exercise can enhance bone mineral density in different degrees.
OBJECTIVE: To investigate the effect of volleyball exercise on bone mineral density in females and its age and side differences.
METHODS: Totally 112 participants were divided into young experimental (n=20) and control (n=20) groups, middle-aged experimental (n=20) and control (n=18) groups, and elderly experimental (n=18) and control (n=16) groups. The participants in each experimental group were the female volleyball teachers or those females who performed long-term volleyball exercise, while those in each control group were female teachers, but almost no contact with volleyball. The bone mineral density of the bilateral distal radius 1/3 and L2-L4 vertebrae was measured using Prodigy type Advance dual energy X-ray absorptiometry produced by the United States GE company. Independent-Sample T Test and one-way ANOVA were performed on SPSS 20.0 software.
RESULTS AND CONCLUSION: The bone mineral density of the radius in the experimental groups was significantly higher than that in the control groups at each age bracket (P < 0.05). The L2-L4 bone mineral density in the elderly experimental group was significantly higher than that in the elderly control group (P < 0.05). The observation indexes were significantly different in the elderly and the other two age bracket groups (P < 0.05). These results imply that volleyball exercise has a positive effect on the bone mineral density of radius especially the right radius and lumbar in females. The effect of this exercise on the bone mineral density of radius is different between two sides due to different exercise loads on two arms and lumbar spine in females. Moreover, volleyball exercise can effectively delay the loss of bone mass in the older adults.
