This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They had all retired from competitive sport an average of 30 years (range 7-50) ago. Sixty-six age-matched volunteers served as controls. The bone mineral density (BMD, areal density, g/cm2) in the total body, spine, and hips and the fat content and lean body mass were measured with the LUNAR DPX bone mass scanner. In ex-weight lifters 50-64 years of age, the BMD was greater than in controls. After 65 years, no difference was found between the former weight lifters and their controls.
本横断面研究旨在确定早期、长期且高强度的体育锻炼对骨矿物质密度（BMD）是否具有终身有益影响。48名男性前举重运动员参与了研究，他们的平均年龄为64岁（范围50 - 79岁）。他们平均每周进行10小时（范围4 - 20小时）的训练计划，平均持续了13年（范围1 - 34年）。他们均已从竞技体育退役，平均退役时间为30年（范围7 - 50年）。66名年龄匹配的志愿者作为对照。使用LUNAR DPX骨密度扫描仪测量全身、脊柱和髋部的骨矿物质密度（BMD，面积密度，g/cm²）以及脂肪含量和瘦体重。在50 - 64岁的前举重运动员中，BMD高于对照组。65岁以后，前举重运动员与其对照组之间未发现差异。
