中文摘要:

通过进行zebris步态测试和后足角度拍摄，采集和分析速度变化对步行和跑步时后足角度和足偏角的影响，从而科学指导广大健身爱好者进行合理的步行和跑步运动，预防运动损伤。实验结果显示：（1）相较于自身步行偏好速度，采用实验步行设定速度时左右足后足角度均显著增大，左右足足偏角均显著减小（1.33 m/s例外）；（2）实验步行设定速度之间，相较于1.33 m/s速度步行，以1.56 m/s和1.78 m/s步行时左足后足角度显著增大，以1.56 m/s步行时右足足偏角显著减小；（3）相较于自身跑步偏好速度，当以慢于自身跑步偏好速度跑步时，左右足后足角度和足偏角均无显著性差异，而当以快于自身跑步偏好速度跑步时，左右足的足偏角显著减小，后足角度无显著性差异；（4）快于自身跑步偏好速度时比慢于自身跑步速度时左右足的足偏角显著减小（以3.61 m/s跑步时比1.78 m/s跑步时左足后足角度增大）；（5）快于自身跑步偏好速度时，以3.61 m/s跑步时比2.78 m/s跑步时左右足足偏角显著减小。实验结果表明：（1）相较于其他实验设定速度，以自身偏好速度步行时，后足角度较小，足偏角较大，可以有效预防运动损伤；（2）从后足角度和足偏角考虑，当步行速度较快时，保持步长，适当减小足偏角可以减少踝关节损伤。

英文摘要:

The influence of walking and running speed on rear foot angle and foot progression angle is collected and analyzed by Zebris gait tests and digital photographs in order to scientically instruct a vast number of fitness enthusiasts to walk and run rationally and prevent sports injury. The result of the study shows that:(1) Compared to preferred walking speed, the left and right rear foot angle significantly increased and the left and right foot progression angle obviously reduced when walking at a set speed（except 1.33m/s）;(2) While walking with the set speed, compared to 1.33m/s, the left rear foot angle significantly increased when walking at 1.56m/s and 1.78m/s, and right foot progression angle significantly reduced when walking at 1.56m/s;(3) Compared to preferred running speed, there was no significant difference in rear foot angle and foot progression angle when running at the speed slower than the preferred running speed. However, left and right foot progression angle significantly reduced and no significant difference in rear foot angle when running at the speed faster than the preferred running speed;(4) Compared to the running speed slower than the preferred speed, left and right foot progression angle significantly reduced when running at a faster speed (the rear foot angle of the left foot increased when running at the speed of 3.61m/s than running at 1.78m/s); (5) Compared to 2.78m/s, left and right foot progression angle significantly reduced when running at 3.61m/s. In conclusion, Compared to other experimental setting speed, rear foot angle is smaller and foot progression angle is greater at the preferred walking speed. This can effectively prevent injuries. In terms of rear foot angle and foot progression angle, it is best to keep step length and decrease foot progression angle properly when walking at a fast speed. In this way, ankle injury can be prevented.
