The skeleton of the hand fingers was studied roentgenographically and osteometrically in swimmers 8--10 and 17--19 years of age. As the investigation demonstrated, it is necessary to take into account sports selection in order to study adaptive peculiarities of the osseous system in young sportsmen. Increasing rate in osteogenesis noted in the hand bones of swimmers 8--10 years old does not result from increasing physical loading on the hand but is a cause of the original selection of more physically suitable and biologically mature children for swimming. In order to study adaptive peculiarities of the most loaded skeletal parts in sportsmen, it is necessary to compare them rather with other sportsmen experiencing physical loading on similar skeletal parts, and differing only in the mode of performance, but not with persons nonsportsmen. Uniform lengthening of the metacarpal bones and uniform thickening of their compact substance on the radial and ulnar sides symmetrically on both hands is one of specific morphological features of the swimmers' hands adaptation to physical loadings.
对8至10岁和17至19岁游泳运动员的手部手指骨骼进行了X射线摄影和骨测量研究。研究表明,为了研究年轻运动员骨骼系统的适应性特点,有必要考虑运动选材因素。8至10岁游泳运动员手部骨骼成骨速率的增加并非源于手部物理负荷的增加,而是最初选拔出身体更合适、生物学上更成熟的儿童进行游泳运动的结果。为了研究运动员中负荷最大的骨骼部位的适应性特点,有必要将他们与其他在类似骨骼部位承受物理负荷、仅表现方式不同的运动员进行比较,而不是与非运动员进行比较。双手掌骨均匀延长以及其致密物质在桡侧和尺侧对称均匀增厚是游泳运动员手部适应物理负荷的特定形态特征之一。
