Energy transformation during erect and 'bent-hip, bent-knee' walking by humans with implications for the evolution of bipedalism.

Abstract

We have previously reported that predictive dynamic modeling suggests that the 'bent-hip, bent-knee' gait, which some attribute to Australopithecus afarensis AL-288-1, would have been much more expensive in mechanical terms for this hominid than an upright gait. Normal walking by modern adult humans owes much of its efficiency to conservation of energy by… (More)
