Our goal was to test the effect of a brief, novel bone- and fat-targeted exercise program on bone, muscle, and fat in healthy pre and peripubertal boys. We conducted a 10-min, 3/wk capoeira and jumping exercise intervention for 9 months with year 5 and 6 school boys. Anthropometrics, maturity, heart rate, blood pressure, maximal vertical jump, aerobic capacity and calcaneal broadband ultrasound attenuation and stiffness index (BUA and SI; Achilles, GE) were assessed. Bone, lean and fat tissue (DXA; XR800, Norland), and parameters of bone geometry (pQCT, XCT3000, Stratec) were measured from a subsample of 36 boys. Of 188 boys (10.6 ± 0.5 yr) who consented, 172 completed all testing; 104 exercisers (EX) and 68 controls (CON). 30 EX and 6 CON participants underwent DXA and pQCT measures. EX improved BUA (+4.3% vs. +2.1%, p = .035), waist circumference (+2.8% vs. +6.2%, p = .001), heart rate (-5.3% vs. +1.5%, p = .005), maximal vertical jump (+12.2% vs. -0.3%, p = .001) and estimated maximal oxygen consumption (+9.1% vs. +1.2%, p = .001) compared with CON. Three 10-min sessions of capoeira and jumping per week improved calcaneal bone and metabolic health of pre and peripubertal boys over the course of a school year with little disruption to the academic schedule.
我们的目标是测试一项简短、新颖的针对骨骼和脂肪的运动计划对健康的青春期前和青春期早期男孩的骨骼、肌肉和脂肪的影响。我们对五年级和六年级的男学生进行了为期9个月、每周3次、每次10分钟的卡波耶拉舞和跳跃运动干预。评估了人体测量学指标、成熟度、心率、血压、最大垂直跳跃高度、有氧能力以及跟骨宽带超声衰减和硬度指数（BUA和SI；跟腱、跟骨）。从36名男孩的子样本中测量了骨骼、瘦组织和脂肪组织（双能X线吸收法；Norland公司的XR800）以及骨几何参数（外周定量CT，XCT3000，Stratec公司）。在188名同意参与的男孩（10.6±0.5岁）中，172名完成了所有测试；104名运动组（EX）和68名对照组（CON）。30名运动组参与者和6名对照组参与者接受了双能X线吸收法和外周定量CT测量。与对照组相比，运动组的跟骨超声衰减（+4.3%对+2.1%，p = 0.035）、腰围（+2.8%对+6.2%，p = 0.001）、心率（-5.3%对+1.5%，p = 0.005）、最大垂直跳跃高度（+12.2%对-0.3%，p = 0.001）和估计最大耗氧量（+9.1%对+1.2%，p = 0.001）均有改善。在一学年的时间里，每周进行三次10分钟的卡波耶拉舞和跳跃运动，在对学业安排几乎没有干扰的情况下，改善了青春期前和青春期早期男孩的跟骨骨骼和代谢健康状况。
