对近东中旧石器时代人类胫骨骨干强健性的外部骨测量评估已被用于论证该地区中旧石器时代晚期古人类和早期现代人在运动负荷机制上的显著差异。根据身体质量和梁长度的生物力学适当测量，对胫骨干骨强度的横截面几何形状进行重新评估显示，近东晚期古人类和Qafzeh-Skhul早期现代人类样本之间没有显著差异。这与他们的运动强度和耐力的比较水平的其他评估一致，表明一旦适当地将体重和梁长纳入分析，他们下肢的总负荷水平相似。同时，在这些样本之间，无论是在横截面内的相对皮质面积，还是骨的生物力学相关分布（由垂直的面积秒矩表示），都没有系统的差异。通过对这些NEMP胫骨的强度进行适当的测量（无论使用的估计多么精确），得出的结论是，与之前的评估相反，没有理由推断出在旧石器时代中期近东的晚期古人类和早期现代人之间运动活动水平或模式的显著变化。
External osteometric assessments of Near Eastern Middle Palaeolithic human tibial diaphyseal robusticity have been used to argue for significant differences in locomotor loading regimes between late archaic and early modern humans from the Middle Palaeolithic of that region. Reassessment of tibial diaphyseal strength using cross-sectional geometry of their shafts scaled against biomechanically appropriate measures of body mass and beam length reveals no significant difference between the Near Eastern late archaic human and Qafzeh-Skhul early modern human samples. This is in agreement with other assessments of their comparative levels of locomotor strength and endurance indicating similar levels of summed loads upon their lower limbs once body mass and beam length are appropriately incorporated into the analysis. At the same time, there are no systematic differences in either relative cortical area within cross-sections or the biomechanically relevant distribution of bone (indicated by perpendicular second moments of area) between these samples. What emerges from a consideration of appropriately scaled measures of strength of these NEMP tibiae (however precise the estimates employed) is that, contrary to previous assessments, there are no grounds for inferring a significant change in locomotor activity levels or patterns between late archaic and early modern humans in the Near Eastern Middle Palaeolithic.
