Pose® Method gait retraining has been claimed to modify running form and prevent injury. This study examined the running biomechanics before and after Pose® Method gait retraining. Fourteen runners underwent a 4-week Pose® Method gait retraining program delivered by a certified coach. Paired t-tests were employed to compare vertical average (VALR) and instantaneous loading rates (VILR), lower limb kinematics, footstrike angle and trunk flexion in the sagittal plane before and after the training. Kinetically, there were no significant differences in the VALR (= 0.693) and VILR (= 0.782) before and after the training. Kinematically, participants exhibited greater peak hip flexion (= 0.008) and knee flexion (= 0.003) during swing. Footstrikeangle also reduced significantly (= 0.008), indicating a footstrike pattern switch from rearfoot strike to midfoot strike. There was no significant difference in the trunk flexion in the sagittal plane after training (= 0.658). After a course of Pose® Method gait retraining, runners demonstrated a footstrike pattern switch and some kinematics changes at the hip and knee joint during swing. However, injury-related biomechanical markers (e.g., VALR and VILR) and the trunk kinematics remained similar after training. Runners may consider other gait retraining programs for impact loading reduction.
姿势®方法步态再训练据称可以改变跑步姿势并预防受伤。本研究在姿势®方法步态再训练前后检查了跑步的生物力学。14 名跑步者由经过认证的教练进行了为期 4 周的姿势®方法步态再训练计划。使用配对 t 检验比较了训练前后垂直平均（VALR）和瞬时加载率（VILR）、下肢运动学、足跟着地角度和矢状面躯干屈曲。动力学上，训练前后 VALR（=0.693）和 VILR（=0.782）无显著差异。运动学上，摆动时参与者的髋关节最大屈曲（=0.008）和膝关节最大屈曲（=0.003）更大。足跟着地角度也显著减小（=0.008），表明从后足着地到中足着地的着地模式发生了转变。训练后矢状面躯干屈曲无显著差异（=0.658）。经过一段时间的姿势®方法步态再训练，跑步者在摆动时表现出足跟着地模式的转变以及髋关节和膝关节的一些运动学变化。然而，训练后与受伤相关的生物力学指标（如 VALR 和 VILR）和躯干运动学仍然相似。跑步者可能会考虑其他步态再训练计划来减少冲击载荷。
