Abstract
During walking, humans tend to select a movement strategy that conserves the most metabolic energy. The ability to walk economically requires the optimization of a variety of factors, including changes in stride characteristics. While gross variation of strides is related to energy consumption, how this variation is organized from stride to stride may also contribute to metabolic economy. The purpose of this study is determine the relationship between metabolic energy consumption, stride variability, and stride-to-stride organization. By measuring stride length and gas exchange across a range of treadmill walking speeds, we will be investigating how the magnitude of stride length fluctuations relates to the organization of the fluctuations, and how these both relate to metabolic energy expenditure. We expect that both measures will be correlated with metabolic cost of transport, indicating that walking economically requires appropriate stride length maintenance and organization.
