In a recent randomised trial investigating running shoe cushioning, injury risk was greater in recreational runners who trained in the shoe version with greater cushioning stiffness (Stiff) compared to those using the Soft version. However, vertical impact peak force (VIPF) was lower in the Stiff version. To investigate further the mechanisms involved in the protective effect of greater cushioning, the present study used an intra-subject design and analysed the differences in running kinematics and kinetics between the Stiff and Soft shoe versions on a subsample of 41 runners from the previous trial. Data were recorded in the two shoe conditions using an instrumented treadmill at 10 km.h. VIPF was confirmed to be lower in the Stiff version compared to the Soft version (1.39 ± 0.25 vs. 1.50 ± 0.25 BW, respectively; = 0.009, = 0.42), but not difference was observed in vertical loading rate ( = 0.255 and 0.897 for vertical average and instantaneous loading rate, respectively). Ankle eversion maximal velocity was not different ( = 0.099), but the Stiff version induced greater ankle negative work (-0.55 ± 0.09 vs. -0.52 ± 0.10 J.kg; = 0.009, = 0.32), maximal ankle negative power (-7.21 ± 1.90 vs. -6.96 ± 1.92 W.kg; = 0.037, = 0.13) and maximal hip extension moment (1.25 ± 0.32 vs.1.18 ± 0.30 N.m.kg; = 0.009, = 0.22). Our results suggest that the Stiff shoe version is related to increased mechanical burden for the musculoskeletal system, especially around the ankle joint.

在最近一项调查跑鞋缓冲性能的随机试验中，与使用软款跑鞋的休闲跑步者相比，穿着缓冲硬度更大的跑鞋（硬款）进行训练的跑步者受伤风险更高。然而，硬款跑鞋的垂直冲击峰值力（VIPF）较低。为了进一步研究更大缓冲保护作用的相关机制，本研究采用了受试者内设计，并分析了来自先前试验的41名跑步者子样本在硬款和软款跑鞋条件下跑步运动学和动力学的差异。使用装有仪器的跑步机在10 km/h的速度下记录两种跑鞋条件下的数据。与软款跑鞋相比，硬款跑鞋的VIPF确实更低（分别为1.39 ± 0.25与1.50 ± 0.25 BW；P = 0.009，η² = 0.42），但垂直负荷率未观察到差异（垂直平均负荷率和瞬时负荷率的P分别为0.255和0.897）。踝关节外翻最大速度没有差异（P = 0.099），但硬款跑鞋导致更大的踝关节负功（-0.55 ± 0.09与-0.52 ± 0.10 J.kg；P = 0.009，η² = 0.32）、最大踝关节负功率（-7.21 ± 1.90与-6.96 ± 1.92 W.kg；P = 0.037，η² = 0.13）和最大髋关节伸展力矩（1.25 ± 0.32与1.18 ± 0.30 N.m.kg；P = 0.009，η² = 0.22）。我们的结果表明，硬款跑鞋与肌肉骨骼系统，尤其是踝关节周围的机械负荷增加有关。ClinicalTrials.gov标识符：NCT03115437。
