...Luke N. Jessup; Luke A. Kelly; Andrew G. Cresswell; Glen A. Lichtwark Many models have been developed to predict metabolic energy expenditure based on biomechanical proxies of muscle function. However, current models may only perform well for select forms of locomotion, not only because the models...

... that bones experience. If locomotion imposed lower loads in trees than on the ground, such a release from loading demands might have produced conditions under which potential constraints on the evolution of long limbs were removed, making it easier for them to evolve in arboreal species. We tested...

...Nikolaos Papachatzis; Samuel F. Ray; Kota Z. Takahashi ABSTRACT Foot structures define the leverage in which the ankle muscles push off against the ground during locomotion. While prior studies have indicated that inter-individual variation in anthropometry (e.g. heel and hallux lengths) can...

...Jeffrey Hainer; Keegan Lutek; Hailey Maki; Emily M. Standen ABSTRACT Control of locomotion involves the interplay of sensory signals and motor commands. Sensory information is essential for adjusting locomotion in response to environmental changes. A previous study using mathematical modelling...

For walking animals (which we define as encompassing any form of legged movement across the ground, such as walking, running, galloping, etc.), such substrate ‘roughness’ influences locomotion in a multitude of ways across scales, from roughness that influences how each toe or foot contacts the ground...

This article considers how study setting influences the selection of animals, behaviors and methodologies for studying animal motion. We highlight the benefits of both field- and laboratory-based studies and discuss how recent work leverages...

We also highlight the external factors contributing to the evolution of this technology, including recent advancements in machine learning, and the influx of interest in cheetah biomechanics from the legged robotics community. Many of the emerging...
