| 探讨不同运动强度的健身跑对促进女性大学生骨骼健康的效果。方法：选取51名女性大学生，设计不同运动强度的健身跑干预方案，进行为期12个月的运动干预，其中实验1组（较大运动强度组）15人，运动时心率控制在140—160次/min,实验2组（中小运动强度组）16人，运动心率控制在100—120次/min,实验对照组20人，在实验前后分别测试研究对象的骨密度（BMD）、血清碱性磷酸酶（ALP）、血清骨钙素（BGP）。结果：①实验1组的股骨BMD、血清ALP、血清BGP实验前后比较及实验后与对照组比较差异具有高度显著性（P＜001），腰椎BMD差异具有显著性（P＜005），尺桡骨BMD差异不具有显著性；②实验2组的股骨BMD、血清ALP、血清BGP实验前后比较及实验后与对照组比较差异具有显著性（P＜005）；腰椎BMD、尺桡骨BMD差异不具有显著性。结论：①较大运动强度的健身跑锻炼在促进青年女性骨健康方面效果显著，健骨效果优于中小强度的健身跑；②健身跑运动对人体BMD的影响存在部位特异性 |

| Abstract: |
| Objective: To explore the effect of fitness exercise with different running intensity on promoting bone health of female college students. Method:Fifty one female college students are selected. The fitness running intervention programs with different exercise intensities are designed for a period of 12 months of exercise intervention. In the experimental Group One(heavier intensity, 15 students), the heart rate is controlled at 140-160 times / min, in the experimental Group Two( moderate intensity, 16 students), the heart rate is controlled at 100-120 times / min, in the Control Group, there are 20 students. BMD, serum ALP and serum BGP are measured respectively before and after the experiment. Results: ①Group One’s femoral BMD, serum ALP and serum BGP before the experiment has a highly significant difference with that measured after the experiment, and femoral BMD, serum ALP and serum BGP after experiment has highly significant difference compared with control group (P < 001), lumbar BMD has a significant difference (P < 005), ulna and radius BMD has no significant difference; ②Group Two’s femoral BMD, serum ALP and serum BGP before the experiment has a significant difference with that measured after the experiment, and femoral BMD, serum ALP and serum BGP after experiment has a significant difference compared with control group (P< 005), both lumbar BMD and ulna and radius BMD have no significant difference. Conclusions: ①The heavier intensity of running exercise has remarkable effect in promoting young female bone health, its bone enhancing effect is greater than that of moderate intensity running exercises. ② The influence of fitness running on the human body’s BMD is varies from different bones |
