女子足球运动员与无运动训练女大学生腰椎、股骨颈骨密度比较

目的:探讨足球运动对女性骨密度(BMD)的影响。方法:选择女子足球运动员36例作为实验组,年龄19.56±1.46岁(17～23岁),参加足球运动2年,每年至少参加10个月足球运动。另选在校就读学生33例作为对照组,年龄19.82±1.78岁(17～23岁),2年间仅参加学校规定体育课程的运动。应用双能X线吸收法测量2年实验前后腰椎和股骨颈骨密度。结果:实验组实验后腰椎和股骨颈骨密度较实验前分别上升了2.25%(P>0.05)和4.90%(P<0.05),对照组分别上升0.89%(P>0.05)和2.03%(P>0.05)。与对照组相比,实验组实验后腰椎、股骨颈骨密度显著升高(P<0.05)。结论:长期参与足球运动的年轻女性运动员与无运动训练女性相比可获得更高的骨密度。

A Comparison of Bone Mineral Density between Female Soccer Players and Sedentary College Students

Objective To determine the effect of high-intensity physical activity on bone mineral density(BMD). Methods Thirty-six female soccer players (19.56±1.46 years) with more than two years training history and at least ten months soccer training annually were recruited as experiment group. Thirty-three female sedentary college students, whose physical activities were limited to the compulsory physical education curriculum,were assigned to the control group. BMD of lumbar spine and femoral neck were obtained before and after 24 months research,using dual energy X-ray absorptiometry. Results After 24 months research, increased BMD were found in both groups. Soccer players had 2.25% increase of lumbar spine BMD(P<0.05) and 4.90% increase of femoral neck BMD(P<0.05). Sedentary college students had 0.89% increase of lumbar spine BMD(P>0.05) and 2.03% increase of femoral neck BMD(P>0.05). Compared with sedentary college students,Lumbar spine and femoral neck BMD in soccer players were significantly higher(P<0.05) after 24 months research. Conclusion Long-term soccer training had the effect of greater acquisition of BMD.
