背景：跑鞋的设计适应各种足弓类型，以减少跑步过程中下肢受伤的风险。然而，很少有人知道的生物力学的变化，在推荐的鞋，可能会允许减少injuries.Purpose：为了评估运动控制和缓冲教练鞋对低，高拱runners.Study设计：控制实验室study.Methods：20个高拱和20个低拱休闲跑步者（> 10英里，每周）被招募的研究。当受试者以3.5 ms（-1）+/- 5%沿着跑25 m跑道时，采集三维运动学和动力学数据。所评估的运动控制鞋是New Balance 1122，并且所评估的缓冲鞋是New Balance 1022。重复测量方差分析，以确定是否低，高拱跑步者不同的运动控制和缓冲教练shoes.Results：一个显着的相互作用，观察到在瞬时负荷率，使低拱跑步者有一个较低的瞬时负荷率在运动控制条件，和高拱跑步者有一个较低的瞬时负荷率在缓冲教练条件。鞋显着的主要影响，观察峰值正胫骨加速度，峰值到峰值胫骨]加速度，平均负荷率，峰值外翻，外翻excursion.Conclusion：这些结果表明，运动控制鞋控制后足运动比缓冲教练鞋。此外，缓冲训练鞋衰减冲击比运动控制鞋做。然而，除了瞬时负荷率，这些好处并没有不同的足弓type.Clinical相关性：跑步鞋的建议应根据个人的运行力学。如果机械分析不可用，则鞋类推荐可以基于个人的足弓类型的经验。
Background: Running shoes are designed to accommodate various arch types to reduce the risk of lower extremity injuries sustained during running. Yet little is known about the biomechanical changes of running in the recommended footwear that may allow for a reduction in injuries.Purpose: To evaluate the effects of motion control and cushion trainer shoes on running mechanics in low- and high-arched runners.Study Design: Controlled laboratory study.Methods: Twenty high-arched and 20 low-arched recreational runners (> 10 miles per week) were recruited for the study. Three-dimensional kinematic and kinetics were collected as subjects ran at 3.5 ms(-1) +/- 5% along a 25-m runway. The motion control shoe evaluated was the New Balance 1122, and the cushioning shoe evaluated was the New Balance 1022. Repeated-measures analyses of variance were used to determine if low- and high-arched runners responded differently to motion control and cushion trainer shoes.Results: A significant interaction was observed in the instantaneous loading rate such that the low-arched runners had a lower instantaneous loading rate in the motion control condition, and the high-arched runners had a lower instantaneous loading rate in the cushion trainer condition. Significant main effects for shoe were observed for peak positive tibial acceleration, peak-to-peak tibia] acceleration, mean loading rate, peak eversion, and eversion excursion.Conclusion: These results suggest that motion control shoes control rearfoot motion better than do cushion trainer shoes. In addition, cushion trainer shoes attenuate shock better than motion control shoes do. However, with the exception of instantaneous loading rate, these benefits do not differ between arch type.Clinical Relevance: Running footwear recommendations should be based on an individual's running mechanics. If a mechanical analysis is not available, footwear recommendations can be based empirically on the individual's arch type.
