The aim of this study was to examine the effect of basketball practice on bone acquisition in the prepubertal age. In total, 48 prepubescent male basketball players aged 11.1 ± 0.8 yr, Tanner stage 1, were compared with 50 controls matched for age and pubertal stage. Areal bone mineral density, bone mineral content (BMC), and bone area (BA) in deferent sites associated with anthropometric parameters were measured by dual-energy X-ray absorptiometry. Running and jumping tests were performed. Analysis of Student's impaired t-test revealed that basketball players attained better results in all physical fitness tests (p < 0.05). They also exhibited significantly greater BMC and BA in whole body, upper and lower extremities, trochanter, total hip, and whole right and left radius (p < 0.001) compared with the controls. No significant differences were observed between groups in right and left ultradistal and third distal radius and spinal regions, BMC, and BA, whereas a significant positive correlation was reported between lean mass, BMC, and BA of lower limbs. In summary, basketball practice in prepubertal age is associated with improved physical fitness and enhanced lean and bone mass in loaded sites.
本研究旨在探讨篮球练习对青春期前骨量获得的影响。共比较了 48 名 11.1 ± 0.8 岁、Tanner 分期 1 期的青春期前男性篮球运动员和 50 名年龄和青春期阶段相匹配的对照组。使用双能 X 射线吸收法测量了与人体测量参数相关的不同部位的面积骨矿物质密度、骨矿物质含量（BMC）和骨面积（BA）。进行了跑步和跳跃测试。学生 t 检验分析显示，篮球运动员在所有体能测试中都取得了更好的成绩（p < 0.05）。与对照组相比，他们在全身、上下肢、转子间区、总髋部以及整个右侧和左侧桡骨中表现出显著更高的 BMC 和 BA（p < 0.001）。在右侧和左侧桡骨远端和第三远端以及脊柱区域、BMC 和 BA 方面，两组之间未观察到显著差异，而下肢的瘦体重、BMC 和 BA 之间呈显著正相关。总之，青春期前进行篮球练习与改善的身体素质以及负重部位的瘦体重和骨量增加有关。
