The aim of this study was to determine the influence of barefoot running on foot-strike patterns, eversion-inversion, running speed and vertical foot rotation in endurance runners. Eighty healthy recreational runners (age = 34.11 ± 12.95 years old, body mass index = 22.56 ± 2.65 kg · m(-2)) performed trials in shod/unshod running conditions on a treadmill at comfortable and competitive self-selected speeds. Data were collected by systematic observation of lateral and back recordings at 240 Hz. McNemar's test indicated significant differences between shod/unshod conditions and foot strike at comfortable and competitive speeds (P < 0.001). Speed was related to vertical foot rotation type for shod (P < 0.01) and unshod conditions (P < 0.05). Significant differences were found between shod/unshod conditions in foot rotation at comfortable running speeds (P < 0.001) and competitive running speeds (P < 0.01). No significant difference was found in inversion or eversion (P ≥ 0.05). In conclusion, the results suggest that running kinematics, in terms of foot-strike patterns and vertical foot rotation, differ between shod/unshod conditions, while the inversion or eversion degree remains unchanged.
本研究的目的是确定赤足跑步对耐力跑者的着地方式、内翻-外翻、跑步速度和足部垂直旋转的影响。80名健康的业余跑者（年龄=34.11±12.95岁，体重指数=22.56±2.65kg·m⁻²）在跑步机上以舒适和自定的竞技速度进行了穿鞋/不穿鞋跑步条件下的测试。通过以240Hz对侧面和背面记录进行系统观察来收集数据。McNemar检验表明，在舒适和竞技速度下，穿鞋/不穿鞋条件与着地方式之间存在显著差异（P<0.001）。在穿鞋（P<0.01）和不穿鞋条件下（P<0.05），速度与足部垂直旋转类型有关。在舒适跑步速度（P<0.001）和竞技跑步速度（P<0.01）下，穿鞋/不穿鞋条件在足部旋转方面存在显著差异。在内翻或外翻方面未发现显著差异（P≥0.05）。总之，结果表明，在着地方式和足部垂直旋转方面，跑步运动学在穿鞋/不穿鞋条件下有所不同，而内翻或外翻程度保持不变。
