Gait Dynamics and Locomotor Metabolism

Abstract

The proposed work has three objectives to improve prediction and assessment capabilities. The first objective is to determine if the generalized equation provided by our new gait mechanics model predicts the metabolic cost of weighted and unweighted walking more accurately than existing generalized equations. The second objective is to determine how accurately weighted and unweighted walking metabolic rates can be estimated in field settings from simple technologies. The third objective is to develop a walking test of aerobic fitness. Metabolic rates will be measured from expired gases. The timing of each walking stride, as well as its subcomponents will be determined from video. In addition, periods of muscular activity will be also assessed from electrical activity using surface electrodes attached to the skin above target muscles. The forces that subjects apply to the ground during locomotion may be measured from either a force plate or force sensors built into a treadmill. Finally, heart rate monitors to measure heart beat frequency, miniature motion sensors mounted to the shoe or other parts of the body to measure movement speeds and rates may also be utilized.
