简介：有证据表明，青春期前的运动训练可导致骨矿物质增加，这可能会给成年人带来显着的优势。然而，缺乏支持性的前瞻性纵向数据。本研究的目的是评估骨矿物质含量（BMC）的全身（WB），全髋关节（TH），股骨颈（FN）和腰椎（LS）超过四年的青春期前的男孩和女孩7个月的跳跃intervention.Methods：研究人群包括107名女孩和98名男孩年龄在基线8.6 +/- 0.88岁。参与的学校被随机分配为干预学校或对照学校。干预学校的儿童（n = 101）参加了标准体育课程中嵌入的跳跃干预。对照学校的儿童（n = 104）有类似的暴露于体育没有跳跃干预。在基线时、干预后7个月时以及此后3年每年共5次测量机会时通过DXA评估BMC。多水平随机效应模型的构建和用于预测从研究进入BMC参数在每个measurementoccasion.Results的变化：一个显着的干预效果，发现在所有的骨网站。在干预后立即（7个月）效果最大，但在干预后三年仍然显着。在7个月时，干预参与者在LS、TH、FN和WB的BMC值分别比对照组高7.9%、8.4%、7.7%和7.3%（p
Introduction: Evidence suggests bone mineral increases attributable to exercise training prior to puberty may confer a significant advantage into adulthood. However, there is a dearth of supportive prospective longitudinal data. The purpose of this study was to assess bone mineral content (BMC) of the whole body (WB), total hip (TH), femoral neck (FN) and lumbar spine (LS) over four years in pre-pubertal boys and girls following a 7-month jumping intervention.Methods: The study population included 107 girls and 98 boys aged 8.6 +/- 0.88 years at baseline. Participating schools were randomly assigned as either intervention or control school. Children at the intervention school (n = 101) participated in a jumping intervention embedded within the standard PE curriculum. The control school children (n = 104) had similar exposure to PE without the jumping intervention. BMC was assessed by DXA at baseline, at 7-month post intervention, and annually thereafter for three years totaling 5 measurement opportunities. Multi-level random effects models were constructed and used to predict change from study entry in BMC parameters at each measurement occasion.Results: A significant intervention effect was found at all bone sites. The effect was greatest immediately following the intervention (at 7 months) but still significant three years after the intervention. At 7 months, intervention participants had BMC values that were 7.9%, 8.4%, 7.7% and 7.3% greater than the controls at the LS, TH, FN and WB, respectively (p
