Abstract

Minetti and Alexanders (1997) theoretical model of bipedal gaits succeeded in predicting the form of relationships between stride length, speed, duty factor, and ground reaction force. Computational problems in optimisation limited model biofidelity resulting in underestimation of metabolic costs and duty factors, and overestimation of shape factors. Realistic models are now computationally tractable using genetic algorithm- and finite points- based optimisation techniques. These approaches will be used to produce improved models of bipedal and then quadrupedal gaits, which will be verified against real world data and used to analyse the mechanics and ontogeny of gait, and its physiological costs.
