摘　　要：目的探讨健美操运动对普通大学生骨密度(BMD)和部分骨代谢指标的影响,为了解运动对青春后期大学生骨代谢的影响提供依据。方法以江西师范大学40名健康男大学生作为研究对象,比较运动组(健美操)和对照组(较少参加运动)的骨密度和血清睾酮、血碱性磷酸酶(ALP)、尿羟脯氨酸(U-HOP)及尿肌酐(U-Cr)等骨代谢指标。结果与对照组相比,运动组的腰椎(L2-4)和左股骨颈骨密度均较高,腰椎骨密度差异有统计学意义;运动组的血清睾酮明显高于对照组,差异有统计学意义;运动组的血ALP要高,而U-HOP和U-HOP/U-Cr比值低,但差异均无统计学意义。结论健美操运动能够通过影响骨代谢来增加骨形成、减少骨吸收,提高青春后期男大学生的骨密度和骨量。Objective To explore the effects of bodybuilding on bone mineral density（BMD） and some indexes of bone metabolism among college students.Methods A total of 40 male students of college were divided into exercise group（participates bodybuilding frequently） and control group（sedentary）,some indexes of bone metabolism and BMD were observed and analyzed.Results The level of bone density and bone mass of spine and left femoral neck in exercise group was relatively higher than control group;the concentration of serum testosterone was remarkably higher than control group（P0.05）;blood ALP was higher,U-HOP and U-HOP/U-Cr ratio were lower in exercise group compared with control group,but failed to reach significant level.Conclusion Regular and moderate bodybuilding exercise is beneficial to the level of resting serum testerosterone in male college students;regular and moderate bodybuilding exercise may affect bone metabolism by increasing the formation of bone and decreasing the absorption of bone to increase the BMD and bone mass.
