移动模式会影响运动过程中施加在下肢上的负载，并可能影响下肢骨干的坚固性和形状的变化。这种关系通常构成从古人类化石和骨骼遗骸推断活动模式的基础。这项研究评估了运动历史之间的对应关系，根据负荷强度、重复性和方向性而变化，使用回忆问卷进行测量，以及外周定量计算机断层扫描衍生的胫骨骨干刚性和形状测量。参与者包括男性大学校队越野跑运动员 (n = 15)、曲棍球运动员 (n = 15) 和对照组 (n = 20) [平均年龄：22.1 (SD +/- 2.6) 岁]。跑步者和曲棍球运动员的胫骨刚性测量值（包括 J、%CA、Imax、Imin 和平均皮质厚度）均大于对照组（P < 或 = 0.05）。跑步者和曲棍球运动员之间胫骨形状的差异（Imax/Imin，P<或= 0.05）反映了跑步者明显的最大平面（Imax）刚性，以及曲棍球运动员之间更对称的肥大（Imax，Imin）。这与跑步者的一般单向运动模式和曲棍球运动员的多向运动模式相对应。这些结果支持了活动性与胫骨骨干形态之间的关系，正如人类学文献中通常解释的那样，较高水平的活动性与骨干坚固性和形状变化的增加相关。尽管运动强度可能是对这些特性的主要影响，但活动的重复性也值得考虑。总之，骨形态模式可以反映习惯行为，对运动活动的适应可能导致考古和化石样本中胫骨刚性和形状特性的变化。
Mobility patterns affect the loads placed on the lower limbs during locomotion and may influence variation in lower limb diaphyseal robusticity and shape. This relationship commonly forms the basis for inferring mobility patterns from hominin fossil and skeletal remains. This study assesses the correspondence between athletic histories, varying by loading intensity, repetition and directionality, measured using a recall questionnaire, and peripheral quantitative computed tomography-derived measurements of tibial diaphysis rigidity and shape. Participants included male university varsity cross-country runners (n = 15), field hockey players (n = 15), and controls (n = 20) [mean age: 22.1 (SD +/- 2.6) years]. Measurements of tibial rigidity (including J, %CA, Imax, Imin, and average cortical thickness) of both runners and field hockey players were greater than controls (P < or = 0.05). Differences in tibial shape (Imax/Imin, P < or = 0.05) between runners and hockey players reflect pronounced maximum plane (Imax) rigidity in runners, and more symmetrical hypertrophy (Imax, Imin) among hockey players. This corresponds with the generally unidirectional locomotor patterns of runners, and the multidirectional patterns of hockey players. These results support the relationship between mobility and tibial diaphysis morphology as it is generally interpreted in the anthropological literature, with greater levels of mobility associated with increased diaphyseal robusticity and shape variation. Although exercise intensity may be the primary influence on these properties, the repetitiveness of the activity also deserves consideration. In conclusion, bone morphological patterns can reflect habitual behaviors, with adaptation to locomotor activities likely contributing to variation in tibial rigidity and shape properties in archaeological and fossil samples.
