我们研究了11名青年健全人穿着5双不同的鞋以自选速度行走时的耗氧率：一双普通鞋，不带摇杆鞋底（REG），四双硬度均匀（35-40海岸A硬度）不同半径（腿长的25%（LL）（R25）、40% LL（R40）、55% LL（R55）和无限半径（FLAT））的摇底。研究中的摇底鞋是为了提供类似的垂直升力而开发的（比REG鞋高出三英寸）。氧消耗率受不同鞋的使用的显著影响（p<0.001），并且成对比较表明，当与FLAT（p<0.001）和REG（p=0.021）鞋条件相比时，穿着R40鞋行走的人消耗的氧（每分钟每千克体重）显著更少。R25鞋的耗氧量也显著低于FLAT鞋（p=0.005），R55鞋的耗氧量也显著低于FLAT鞋（p=0.027）。FLAT鞋上的3英寸提升与没有提升的鞋（REG）相比，没有引起耗氧量的显着变化。
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).
