We studied oxygen consumption rate of eleven young able-bodied persons walking at self-selected speed with five different pairs of shoes: one regular pair without rocker soles (REG) and four pairs with uniform hardness (35-40 shore A durometer) rocker soles of different radii (25% of leg length (LL) (R25), 40% LL (R40), 55% LL (R55), and infinite radius (FLAT)). Rocker soled shoes in the study were developed to provide similar vertical lift (three inches higher than the REG shoes condition). Oxygen consumption rate was significantly affected by the use of the different shoes (p<0.001) and pairwise comparisons indicated that persons consumed significantly less oxygen (per minute per kilogram of body mass) when walking on the R40 shoes when compared with both the FLAT (p<0.001) and REG (p=0.021) shoe conditions. Oxygen consumption was also significantly less for the R25 shoes compared with the FLAT shoes (p=0.005) and for the R55 shoes compared with FLAT shoes (p=0.027). The three-inch lift on the FLAT shoe did not cause a significant change in oxygen consumption compared to the shoe without the lift (REG).
我们研究了 11 名身体健全的年轻人以自选速度行走时的耗氧量，他们穿着 5 种不同的鞋子：1 双普通平底鞋（REG）和 4 双硬度均匀（邵氏 A 硬度计 35-40）、后跟半径不同的弧形鞋底鞋（后跟半径分别为腿长的 25%（R25）、40%（R40）、55%（R55）和无限半径（FLAT））。研究中使用的弧形鞋底鞋旨在提供类似的垂直提升（比 REG 鞋高 3 英寸）。耗氧量明显受到不同鞋子使用的影响（p<0.001），并且两两比较表明，与 FLAT（p<0.001）和 REG（p=0.021）鞋相比，人们穿着 R40 鞋行走时的耗氧量明显减少。与 FLAT 鞋相比，R25 鞋的耗氧量也明显减少（p=0.005），与 FLAT 鞋相比，R55 鞋的耗氧量也明显减少（p=0.027）。与没有提升的鞋子（REG）相比，FLAT 鞋的 3 英寸提升并没有导致耗氧量的显著变化。
