Dr Kayleigh Rose is a post-doctoral researcher at the University of Manchester interested in functional morphology and biomechanics. She completed her PhD at the University of Manchester in 2015 for which she investigated the links between locomotor morphology, energetics and mechanics in selectively bred chickens. She has since been working on projects investigating differences in locomotor performance between wild and domestic birds, adjustments in muscle activity patterns during turning manoeuvres in humans and roles of the axial musculature in lung ventilation in reptilians.
The metabolic cost of transport, the energy required to move a unit body mass over a unit distance, is an important measure in investigating the selection pressures that have shaped animal terrestrial locomotor systems. Large-scale interspecies comparisons are invaluable towards understanding the links between locomotor morphology, kinematics and metabolic cost. However, interspecific comparisons alone are also limiting due to confounding phylogenetic, geometric and physiological factors. Animals selectively bred for different sizes or morphological characteristics offer a unique opportunity to investigate the independent effects of such characteristics. Here, using measurements collected from domestic chickens selected for different body sizes, I present new insights into the links between these integrated components of locomotion. I also demonstrate how sex-specific morphologies influence locomotor parameters pre and post sexual maturity in chickens selected for their egg laying productivity.
