...Glen A. Lichtwark; Luke N. Jessup; Ryan N. Konno; Cristian D. Riveros-Matthey; Taylor J. M. Dick ABSTRACT In this Review, we explore the state of the art of biomechanical models for estimating energy consumption during terrestrial locomotion. We consider different mechanical models that provide...

.... Published by The Company of Biologists Ltd 2023 Summary: Rough substrates influence animal walking based on the relative, not absolute, scale of substrate features; this Review proposes terminology and metrics to enhance comparative study. Locomotion Terrestrial Legged Adhesion Friction...

... posture increases the functional length of the forelimb, thereby contributing to absolutely longer stride lengths ( Patel, 2009 ), and is associated with reduced active muscle volume (this study) supports the proposal that digitigrady in (semi-) terrestrial primates such as baboons may be accompanied...

... ( Rattus norvegicus ) as they moved on horizontal poles of different diameters. The data were compared with data pertaining to terrestrial locomotion. We investigated three-dimensional kinematics and dynamics using biplanar cineradiography with simultaneous substrate reaction force (SRF) measurements...

...Angela R. V. Rivera; Richard W. Blob SUMMARY Turtles use their limbs during both aquatic and terrestrial locomotion, but water and land impose dramatically different physical requirements. How must musculoskeletal function be adjusted to produce locomotion through such physically disparate habitats...

...Andrew R. Lammers; Audrone R. Biknevicius SUMMARY Effects of substrate diameter on locomotor biodynamics were studied in the gray short-tailed opossum ( Monodelphis domestica ). Two horizontal substrates were used: a flat `terrestrial' trackway with a force platform integrated into the surface...

... a unifying general principle and extended from marine to terrestrial ectotherms. By contrast, in insects the upper and lower limits are decoupled, suggesting that the oxygen limitation hypothesis might not be as general as proposed. However, no direct tests of this hypothesis or its predictions have been...

... generalized terrestrial lizard, Dipsosaurus dorsalis . Inclines had significant main effects for relatively few kinematic variables of C. calyptratus (11%)compared to D. dorsalis (73%). For C. calyptratus , the main effects of locomotor surface were nearly three times more widespread than those of incline...

... of locomotor speeds and has a generalized hindlimb morphology relative to some other terrestrial species of lizard ( Fieler and Jayne, 1998 ). Furthermore, extensive background data exist for D . dorsalis for both the limb movements ( Irschick and Jayne, 1999b ; Jayne and Ellis, 1998 ) and the in vitro...

... on the relative magnitude and timing of these patterns of fascicle strain and activation. It has recently been suggested that terrestrial animals may conserve metabolic energy during locomotion by minimizing limb extensor muscle strain during stance, when the muscle is active, facilitating more economical force...

...Gary B. Gillis ABSTRACT Eels ( Anguilla rostrata ) are known to make occasional transitory excursions into the terrestrial environment. While on land, their locomotor kinematics deviate drastically from that observed during swimming. In this study, electromyographic (EMG) recordings were made from...

...Larry M. Frolich; Andrew A. Biewener ABSTRACT Aquatic neotenic and terrestrial metamorphosed salamanders (Ambystoma tigrinurn) were videotaped simultaneously with electromyographic (EMG) recording from five epaxial myotomes along the animal’s trunk during swimming in a flow tank and trotting...
