The current study aimed to comparatively examine the effects of minimalist, maximalist, and conventional footwear on the loads experienced by the patellofemoral joint during running. Twenty male participants ran over a force platform at 4.0 m×s-1. Lower limb kinematics were collected using an 8-camera motion capture system allowing patellofemoral kinetics to be quantified using a musculoskeletal modeling approach. Differences in patellofemoral kinetic parameters were examined using one-way repeated-measures ANOVA. The results showed the peak patellofemoral force and pressure were significantly larger in conventional (4.70 ± 0.91 BW, 13.34 ± 2.43 MPa) and maximalist (4.74 ± 0.88 BW, 13.59 ± 2.63 MPa) compared with minimalist footwear (3.87 ± 1.00 BW, 11.59 ± 2.63 MPa). It was also revealed that patellofemoral force per mile was significantly larger in conventional (246.81 ± 53.21 BW) and maximalist (251.94 ± 59.17 BW) as compared with minimalist (227.77 ± 58.60 BW) footwear. As excessive loading of the patellofemoral joint has been associated with the etiology of patellofemoral pain symptoms, the current investigation indicates that minimalist footwear may be able reduce runners' susceptibility to patellofemoral disorders.
本研究旨在比较极简主义、最大化主义和传统跑鞋对跑步时髌股关节所承受负荷的影响。20名男性参与者以4.0米/秒的速度在测力平台上跑步。使用8台摄像机的运动捕捉系统收集下肢运动学数据，从而能够采用肌肉骨骼建模方法对髌股动力学进行量化。使用单向重复测量方差分析来检验髌股动力学参数的差异。结果显示，与极简主义跑鞋（3.87±1.00体重，11.59±2.63兆帕）相比，传统跑鞋（4.70±0.91体重，13.34±2.43兆帕）和最大化主义跑鞋（4.74±0.88体重，13.59±2.63兆帕）的髌股关节峰值力和压力明显更大。研究还发现，与极简主义跑鞋（227.77±58.60体重）相比，传统跑鞋（246.81±53.21体重）和最大化主义跑鞋（251.94±59.17体重）每英里的髌股关节力明显更大。由于髌股关节的过度负荷与髌股疼痛症状的病因有关，目前的调查表明，极简主义跑鞋可能能够降低跑步者患髌股关节疾病的易感性。
