- Goats decrease hindlimb stiffness when walking over compliant surfaces
Summary: Evidence that goats adjust the stiffness of their hindlimbs when walking on hard and soft surfaces, shedding light on their ability to thrive in variable environments.
- Global dynamics of bipedal macaques during grounded and aerial running
Editors' Choice: Macaques prefer grounded running to walking when they move on two legs because of leg compliance.
- Static stability predicts the continuum of interleg coordination patterns in Drosophila
Summary: A simple stability-based modeling approach can explain why walking insects use different leg coordination patterns in a speed-dependent way.
- Limping following limb loss increases locomotor stability
Highlighted Article: It is possible to increase the stability of a gait by limping over unstable phases and maximizing the time spent in the stable phases of a stride.
- Turbulent flow reduces oxygen consumption in the labriform swimming shiner perch, Cymatogaster aggregata
Summary: Fish show significantly different patterns of positioning, kinematics and oxygen consumption in a typical laboratory flume versus a more turbulent, semi-natural flow, which may have implications for behaviour and energetics measured in the lab.
- Swimming with multiple propulsors: measurement and comparison of swimming gaits in three species of neotropical cichlids
Summary: Differently shaped fish species use varying combinations of body–caudal fin and pectoral fin propulsion at different speeds. Gait is characterized as a trajectory through propulsive parameter space for analysis and comparison.
- Elastic ankle muscle–tendon interactions are adjusted to produce acceleration during walking in humans
Summary: A novel mechanism is presented by which human ankle muscles use their elastic tendons to contribute mechanical work and produce acceleration during walking gait.
- Muscle–tendon mechanics explain unexpected effects of exoskeleton assistance on metabolic rate during walking
Summary: Lower-limb exoskeletons often produce odd adaptations in humans. Muscle-level mechanics and energetics, estimated in data-driven simulations of exoskeleton-assisted walking, can explain why.
- Longitudinal quasi-static stability predicts changes in dog gait on rough terrain
Summary: Dogs co-ordinate their limbs on rough terrain in a manner consistent with optimization for quasi-static longitudinal stability.
- Grizzly bear (Ursus arctos horribilis) locomotion: forelimb joint mechanics across speed in the sagittal and frontal planes
Summary: Joint dynamics of grizzly bears in the sagittal plane are similar to those of other species, and they produce little net work in the frontal plane despite relatively high forces.
