To explore whether collegiate recreational runners of different genders exhibit different lower extremity kinematics following a 5 km running time trial. Thirty collegiate recreational runners (15 males, 15 females) participated. The participants performed kinematic tests using IMUs before and after the 5 km running time trial. Spatiotemporal parameters were recorded via the Garmin HRM-RUN during the 5 km running time trial. The peak hip, knee and ankle joint angles and angular velocity were compared within and between groups using two-way analysis of variance. Spatiotemporal parameters were compared between groups using independent t tests. In terms of kinematic parameters, gender and time have a significant interaction effect on the peak knee internal rotation angle (P = 0.036) after 5 km running time trial. The peak ankle eversion angular velocity after running was significantly greater than that before running in male runners (P = 0.015). In terms of spatiotemporal parameters, the average cadence of females was significantly greater than that of males during running (P = 0.003). The Collegiate recreational runners presented gender-specific lower extremity kinematic characteristics following a 5 km running time trial. The peak knee internal rotation angle significantly increased after the 5 km running time trial in female runners. It should be paid more attention to the association between gender-specific lower extremity kinematic characteristics and running-related injuries in the future.
为探讨不同性别的大学生业余跑步者在5公里计时跑后下肢运动学是否存在差异。30名大学生业余跑步者（15名男性，15名女性）参与研究。参与者在5公里计时跑前后使用惯性测量单元进行运动学测试。在5公里计时跑过程中通过佳明HRM-RUN记录时空参数。使用双向方差分析比较组内和组间的髋、膝、踝关节峰值角度和角速度。使用独立t检验比较组间的时空参数。在运动学参数方面，性别和时间对5公里计时跑后的膝关节峰值内旋角度有显著交互作用（P = 0.036）。男性跑步者跑步后的踝关节峰值外翻角速度显著大于跑步前（P = 0.015）。在时空参数方面，女性跑步时的平均步频显著高于男性（P = 0.003）。大学生业余跑步者在5公里计时跑后呈现出特定性别的下肢运动学特征。女性跑步者在5公里计时跑后膝关节峰值内旋角度显著增加。未来应更多关注特定性别的下肢运动学特征与跑步相关损伤之间的关联。
