摘　　要：Purpose： This study aims to explore the effects of running on different surfaces on the characteristics of in-shoe plantar pressure and tibial acceleration. Methods： Thirteen male recreational runners were required to run at 12 km/h velocity on concrete, synthetic track, natural grass, a normal treadmill, and a treadmill equipped with an ethylene vinyl acetate （EVA） cushioning underlay （treadmill_EVA）, respectively. An in-shoe plantar pressure system and an accelerometer attached to the tibial tuberosity were used to record and analyze the characteristics of plantar pressure and tibial impact during running. Results： The results showed that there were no significant differences in the 1 st and 2nd peak plantar pressures （time of occurrence）, pressure-time integral, and peak pressure distribution for the concrete, synthetic, grass, and normal treadmill surfaces. No significant differences in peak positive acceleration were observed among the five tested surface conditions. Compared to the concrete surface, however, running on treadmillEVA showed a significant decrease in the 1st peak plantar pressure and the pressure time integral for the impact phase （p 〈 0.05）. These can be further ascribed to a reduced peak pressure observed at heel region （p 〈 0.05）. Conclusion： There may not be an inevitable relationship between the surface and the lower-limb impact in runners. It is, however, still noteworthy that the effects of different treadmill surfaces should be considered in the interpretation of plantar pressure performance and translation of such results to overground running.目的:探讨在不同表面上跑步对足底压力和胫骨加速度的影响。方法:13位男性跑步者被要求分别在水泥地、塑胶跑道、天然草地、跑步机以及配备EVA缓冲衬垫物的跑步机上以12 km/h的速度进行慢跑。用足底压力测试系统和安放在胫骨粗隆的加速度计,记录和分析足底压力与胫骨冲击的特点。结果:第一和第二足底压力峰值(发生时间)、压力时间积分、峰值压力分布在混凝土、塑胶、草地和正常的跑步机的表面间没有明显差异。在5种不同测试表面下,峰值加速度正值也无显著差异。但相比于混凝土表面,在配备EVA缓冲衬垫物的跑步机上跑步能明显减小在冲击阶段的足底压力第一峰值和压力积分(p<0.05)。上述结果可进一步归因为足后跟区域峰值压力下降(P<0.05)。结论:运动表面和下肢冲击之间也许并无必然关系。然而值得注意的是,在解释足底压力的表现及将其运用到陆地表面的跑步运动中时应考虑不同跑步机表面的影响。
