Peak bone mass at skeletal maturity may be an important factor in the relative quantity of skeletal mass in old age. We have studied bone mineral in 46 young men, 28 of whom engage in regular and vigorous exercise programs. Spinal trabecular bone mineral density and spinal integral bone mineral content are significantly greater in the exercise group as compared with the 18 control subjects. Of the exercise group, subjects participating in both aerobic and weight-bearing regimens have the greatest spinal bone mineral mass, followed by those engaging in strictly weight-bearing exercise and those in a primarily aerobic program. An analysis of variance across all subject groups, including the control group, shows a significant difference in spinal trabecular bone density based on the type of physical activity.
骨骼成熟时的峰值骨量可能是老年时骨骼质量相对数量的一个重要因素。我们对46名年轻男性的骨矿物质进行了研究,其中28人参与规律且高强度的锻炼计划。与18名对照组受试者相比,运动组的脊椎小梁骨矿物质密度和脊椎整体骨矿物质含量显著更高。在运动组中,同时参加有氧运动和负重运动的受试者脊椎骨矿物质质量最大,其次是那些进行严格负重运动的受试者和主要进行有氧运动的受试者。对包括对照组在内的所有受试者组进行方差分析显示,基于体育活动类型,脊椎小梁骨密度存在显著差异。
