Core strengthening, balance, and flexibility programs such as Pilates have been advocated to positively impact running mechanics and prevent lower extremity injuries. The purpose of this study was to assess the effects of a 12-week mat-based Pilates exercise program on dynamic knee valgus alignment in runners.
Thirty-four novice runners, including young male and female adults performed a running protocol at baseline. The protocol consisted of the participants running on a treadmill at a constant five miles per hour (mph) for 4 min. Post-examination, participants were randomly assigned to a Pilates or control group (n = 16 and n = 18, respectively). A certified Pilates instructor gave the Pilates group a 12-week home-based program. To ensure participants in the Pilates group performed exercises correctly, the Pilates instructor conducted the first session, and provided feedback to each participant. Participants in both groups performed the same running testing protocol every four weeks. Knee valgus was measured as the medial displacement of the knee joint center during the running stance phase. Repeated measures Analysis of Variance (RepANOVA) was calculated at baseline and 4-, 8-, and 12-weeks post examinations to compare knee valgus during running.
Although a reduction in dynamic knee valgus was observed within the Pilates group, the RepANOVA analysis revealed this change was not statistically significant.
Pilates mat-based exercises may improve knee valgus after 12 weeks but a larger sample size, longer intervention duration, or a supervised program should be considered for future research to evaluate its effectiveness.
核心强化、平衡和柔韧性训练计划，如普拉提，已被提倡用于积极影响跑步力学和预防下肢损伤。本研究的目的是评估为期 12 周的垫上普拉提运动方案对跑步者动态膝内翻对齐的影响。
34 名新手跑步者，包括年轻的男性和女性成年人，在基线时进行了跑步测试。该方案包括参与者以恒定的每小时 5 英里（mph）的速度在跑步机上跑步 4 分钟。检查后，参与者被随机分配到普拉提或对照组（n=16 和 n=18）。一位认证的普拉提教练为普拉提组提供了为期 12 周的家庭锻炼计划。为了确保普拉提组的参与者正确地进行练习，普拉提教练进行了第一次课程，并为每个参与者提供了反馈。两组参与者都每四周进行相同的跑步测试方案。在跑步站立阶段，通过测量膝关节中心的内侧位移来测量膝内翻。使用重复测量方差分析（RepANOVA）在基线和 4、8 和 12 周后检查时比较跑步时的膝内翻。
虽然普拉提组的动态膝内翻有所减少，但 RepANOVA 分析显示这种变化没有统计学意义。
普拉提垫上运动可能在 12 周后改善膝内翻，但应考虑更大的样本量、更长的干预持续时间或监督计划，以评估其效果。
