[Purpose] We aimed to clarify and compare the changes in thoracic and lumbar spine motion and to elucidate the relationship between hip and lumbar spine motion during running. [Participants and Methods] Seven healthy females were recruited in this study. Hip and spine movement were measured using a 3D motion analysis system when running at 6, 9, and 12 km/h. One-way analysis of variance was used to compare the changes in hip joint and spine angles during running. Correlation coefficient analysis was used to determine the relationship between the hip and lumbar spine angles at right and left toe-offs. [Results] As the running speed increased, the rotation angles of the thoracic and lumbar spine and the extension angles of the lumbar spine and hip joint significantly increased in the late stance phase. Significant positive relationships were observed between hip flexion and lumbar spine extension angles at toe-off when running at 6 and 9 km/h but not when running at 12 km/h. [Conclusion] To increase the running speed, participants increased the rotation angle of spine and the extension angles of the hip joint and lumbar spine during the stance phase. Participants extended the lumbar spine to compensate for the restricted hip motion at toe-off, which could cause stress to the lumbar spine.
[目的]我们旨在阐明和比较胸腰椎运动的变化，并阐明跑步过程中髋关节与腰椎运动之间的关系。[参与者与方法]本研究招募了7名健康女性。在以6、9和12公里/小时的速度跑步时，使用三维运动分析系统测量髋关节和脊柱的运动。采用单因素方差分析比较跑步过程中髋关节和脊柱角度的变化。使用相关系数分析来确定左右蹬离期髋关节和腰椎角度之间的关系。[结果]随着跑步速度的增加，在站立后期，胸腰椎的旋转角度以及腰椎和髋关节的伸展角度显著增加。在以6和9公里/小时的速度跑步时，蹬离期髋关节屈曲和腰椎伸展角度之间存在显著正相关，但在以12公里/小时的速度跑步时则不存在。[结论]为了提高跑步速度，参与者在站立阶段增加了脊柱的旋转角度以及髋关节和腰椎的伸展角度。参与者伸展腰椎以补偿蹬离期髋关节运动受限，这可能会给腰椎带来压力。
