The main objective of this research was to know how five different cushioning shoes may interfere in ground contact times of each gait phase of walking and running in contrast with barefoot condition. Thirty healthy sport recreational male runners participated in this study. They played over a treadmill wearing minimalist, Boost®, Ethyl-vinyl-acetate (EVA), Air® chamber and pronation-control cushioning shoes technologies and under barefoot condition, recording the last 30 s of walking and running at 5.17 km/h and 9 km/h respectively, while ground contact time duration of each phase of gait was recorded with circular standard pressure sensors located on plantar feet. During walking, the heel contact phase was the station that increased significantly ground contact times wearing all sole cushioning shoes (p < 0.001), excepting no sole shoes (minimalist), versus barefoot condition, being Air® chamber the model that showed the highest times of contact floor versus barefoot (0.28 ± 0.08 ms and 0.23 ± 0.12 ms vs 0.12 ± 0.07 ms and 0.18 ± 0.07 ms in heel contact during midstance phases, respectively). During running, propulsion phase was the station that showed the highest spent times on ground contact with the floor under all shoe conditions, even with minimalist, being again Air® chamber the model with higher significant times in two of three phases versus barefoot (0.11 ± 0.04 ms and 0.16 ± 0.11 ms vs 0.09 ± 0.03 ms and 0.10 ± 0.02 ms in midstance and propulsion phases respectively). Air chamber® was the model too with the most switch ratio to forefoot strike pattern (0.07 ± 0.10 ms to 0.16 ± 0.11 from heel contact to propulsion phase, respectively). In conclusion, a ground contact times increase using all cushioning running shoes compared with barefoot condition was shown in both walking and running test.

这项研究的主要目的是了解与赤脚状况相比，五种不同的缓震鞋如何影响步行和跑步的每个步态阶段的地面接触时间。30名健康体育休闲男选手参加了这项研究。他们在跑步机上穿着极简主义，Boost®，醋酸乙烯酯（EVA），Air®气室和旋前控制缓震鞋技术，并在赤脚条件下跑步，记录了以5.17 km / h的速度行走和跑步的最后30 s，以及分别以9 km / h的速度行走，同时使用位于脚底的圆形标准压力传感器记录每个步态的地面接触持续时间。在步行过程中，脚跟接触阶段是穿着所有鞋底减震鞋的地面接触时间显着增加的站（p <0.001），除了没有鞋底（极简主义）和赤脚状态外，Air®气室模型展示了接触地板和赤脚的最高时间（0.28±0.08 ms和0.23±0.12 ms与脚跟的0.12±0.07 ms和0.18±0.07 ms分别处于中间阶段）。在跑步过程中，推进阶段是在所有鞋子条件下与地面接触都花费最高的时间，即使是极简主义的情况，也是Air®房型，该模式在三个阶段中的两个阶段中的有效时间均比赤脚高（0.11± 0.04毫秒和0.16±0.11毫秒，而中间阶段和推进阶段分别为0.09±0.03毫秒和0.10±0.02毫秒）。空气室®也是前脚打击模式切换率最高的模型（从脚跟接触到推进阶段分别为0.07±0.10 ms至0.16±0.11）。
