This study examined whether participation in high-impact sports during adolescence and adulthood contributes to bone health in males aged 40 years. Data were analyzed on 154 Belgian men aged 13 years at study onset in 1969 and aged 40 years at the end of the 27-year follow-up. In a second analysis, subjects were divided into three groups according to their sports participation history: participation during adolescence and adulthood in high-impact sports (HH; n=18), participation during adolescence in high-impact sports and during adulthood in nonimpact sports or no sports (HN; n=15), and participation during adolescence and adulthood in nonimpact sports or no sports (NN; n=14). Body mass and impact loading during adulthood were significant predictors of total body bone mineral density (BMD) and lumbar spine BMD. Analysis of variance revealed significant differences for lumbar spine BMD between the HH (1.12 g/cm2) group and the HN (1.01 g/cm2) and NN (0.99 g/cm2) groups (F=5.07, p=0.01). Total body BMD was also higher in the HH group at age 40 years, but not significantly (F=3.17, p=0.0515). Covariance analyses for total body BMD and lumbar spine BMD, with body mass and time spent participating in sports as covariates, confirmed these results. Continued participation in impact sports is beneficial for the skeletal health of males aged 40 years.
本研究调查了在青春期和成年期参与高强度运动是否有助于40岁男性的骨骼健康。对1969年研究开始时年龄为13岁、27年随访结束时年龄为40岁的154名比利时男性的数据进行了分析。在第二项分析中，根据运动参与历史将受试者分为三组：青春期和成年期都参与高强度运动（HH组；n = 18）、青春期参与高强度运动而成年期参与非冲击性运动或不运动（HN组；n = 15），以及青春期和成年期都参与非冲击性运动或不运动（NN组；n = 14）。成年期的体重和冲击负荷是全身骨矿物质密度（BMD）和腰椎BMD的重要预测因素。方差分析显示，HH组（1.12 g/cm²）与HN组（1.01 g/cm²）和NN组（0.99 g/cm²）之间的腰椎BMD存在显著差异（F = 5.07，p = 0.01）。40岁时HH组的全身BMD也较高，但差异不显著（F = 3.17，p = 0.0515）。以体重和运动时间为协变量对全身BMD和腰椎BMD进行协方差分析，证实了这些结果。持续参与冲击性运动对40岁男性的骨骼健康有益。
