目的探讨体育锻炼对高校教学科研工作者骨密度(BMD)的影响。方法采用美国X线指骨BMD检测仪对高校教学科研工作者2356人非常用手的食指、中指、无名指的中排指骨BMD进行X线曝光测值。结果无论男性、女性各年龄段BMD正常(normal)人数锻炼组高于未锻炼组。骨量减少(osteopenia)、骨质疏松(osteoporosis)人数未锻炼组高于锻炼组;抽样分析显示无论男女,各年龄组BMD值锻炼组均高于未锻炼组;BMD峰值出现年龄,锻炼组比未锻炼组均推迟(除男20岁年龄组)。结论高校教学科研工作者长期坚持合理的体育锻炼可以使BMD值增加,BMD峰值出现推迟,尤其对孕龄期、哺乳期和绝经期女性BMD影响显著;各年龄段BMD均与合理的体育锻炼呈正相关。
Objective To explore the effect of physical exercise on bone mineral density (BMD) in teaching and research workers in colleges and universities. Methods By using American X-ray phalanx BMD detector, 2356 people in teaching and research workers in university were examined by X-ray exposure of middle finger phalanx BMD of the index finger, middle finger and ring finger. Results Both men and women of all ages had higher BMD normal exercise group than non-exercise group. The number of osteopenia and osteoporosis in non-exercise group was higher than that in exercise group. Sampling analysis showed that the BMD value of exercise group was higher than that of non-exercise group regardless of men’s and women’s age, BMD peak age, exercise group ratio Non-exercise group were postponed (except men 20 years of age group). CONCLUSIONS: Long-term adherence to reasonable physical training by teaching and research workers in colleges and universities can increase the BMD and postpone the peak BMD, especially in BMD of gestational age, lactation and menopausal women. BMD in all age groups is positively correlated with reasonable physical activity Related.
