Low cost of locomotion in the banded Gecko: a test of the nocturnality hypothesis
This study tested the hypothesis that there has been an evolutionary increase in locomotor performance capacity at low temperature in n...
Locomotion. Just skip it
When four-legged animals want to move quickly they gallop -- a gait that was thought to have no equivalent in humans. But a new paper s...
Leg stiffness primarily depends on ankle stiffness during human hopping
When humans hop in place or run forward, they adjust leg stiffness to accommodate changes in stride frequency or surface stiffness. The...
Leg stiffness and stride frequency in human running
When humans and other mammals run, the body's complex system of muscle, tendon and ligament springs behaves like a single linear spring...
Interaction of leg stiffness and surfaces stiffness during human hopping
When mammals run, the overall musculoskeletal system behaves as a single linear 'leg spring'. We used force platform and kinematic meas...
Individual limb work does not explain the greater metabolic cost of walking in elderly adults
Elderly adults consume more metabolic energy during walking than young adults. Our study tested the hypothesis that elderly adults cons...
Independent metabolic costs of supporting body weight and accelerating body mass during walking
The metabolic cost of walking is determined by many mechanical tasks, but the individual contribution of each task remains unclear. We ...
Human hopping on very soft elastic surfaces: implications for muscle pre-stretch and elastic energy storage in locomotion
During hopping in place and running, humans maintain similar center of mass dynamics by precisely adjusting leg mechanics to compensate...
Human hopping on damped surfaces: strategies for adjusting leg mechanics
Fast-moving legged animals bounce along the ground with spring-like legs and agilely traverse variable terrain. Previous research has s...
Human hoppers compensate for simultaneous changes in surface compression and damping
On a range of elastic and damped surfaces, human hoppers and runners adjust leg mechanics to maintain similar spring-like mechanics of ...
