    摘要:

    目的 探究在较慢跑速下,相较于直道跑,弯道跑时两侧下肢髌股关节应力变化,分析长时间弯道跑增加髌股关节痛的可能性。方法 利用Newtest便携测速系统、Motion红外高速运动捕捉系统和Kistler三维测力台,采集13名普通男性大学生(无运动专项)以(4.0±0.2) m/s速度分别沿直道和弯道(内径为36 m)跑步时三维步态参数及地面反作用力。结果 相较于直道跑,弯道跑时外侧腿髌股关节应力增大。弯道跑髌股关节压力变化时未见膝关节屈曲角度和膝关节伸展力矩的显著变化。结论 长时间弯道跑会增加外侧腿患髌股关节痛以及加剧髌股关节痛患者疼痛感,建议跑步爱好者和髌股关节痛患者尽量避免重复长时间弯道跑。

    Abstract:

    Objective To explore the changes in patellofemoral joint stress of lower limbs during curve running at a slower running speed, so as to analyze the possibility of increasing patellofemoral pain due to long curve running. Methods Newtest portable speed measurement system, Motion infrared high speed motion capture system, Kistler three-dimensional force plate were used to collect the kinematic parameters and ground reaction force from a total of 13 male college students without sports specialty at straight track and curve track (with inner diameter of 36 m) at the speed of (4.0±0.2) m/s. Results Compared with linear running, the patellofemoral joint stress at lateral side of the leg significantly increased during curve running. There were no significant differences in knee flexion angles and knee extensor moments when patellofemoral joint stress increased during curve running. Conclusions Long curve running is a contributing factor with respect to the development of patellofemoral pain in lateral leg and aggravating patellofemoral pain. It is suggested that running enthusiasts and patients with patellofemoral pain should avoid repeating long curve running.
