Meeting Abstract 66.3 Thursday, Jan. 6 Neuromuscular Activation Dynamics from Different Types of Motor Units for Predicting Muscle Forces During Locomotion LEE, S/SM*; BIEWENER, A/A; DEBOEF MIARA, M; WAKELING, J/M; Simon Fraser University, Burnaby, Canada; Harvard University, Cambridge, MA; Harvard University, Cambridge, MA; Simon Fraser University, Burnaby, Canada sabrina_lee_4@sfu.ca Neuromuscular activation dynamics are critical to muscle force […]
Energy absorption by muscle during steady and non-steady movement
Meeting Abstract 66.2 Thursday, Jan. 6 Energy absorption by muscle during steady and non-steady movement KONOW, N*; ROBERTS, TJ; Brown University; Brown University nkonow@brown.edu An important function of skeletal muscle is to absorb energy via active lengthening. This occurs in leg extensors during leg flexion and with changes in energetic demand—when running terrain slopes downhill or landing […]
Active Muscle Enhances Rapid Perturbation Recovery in an Insect Limb
Meeting Abstract 66.1 Thursday, Jan. 6 Active Muscle Enhances Rapid Perturbation Recovery in an Insect Limb. LIBBY, T.*; FULL, R. J.; Univ. of California, Berkeley tlibby@berkeley.edu Passive, intact limbs of cockroaches recover from large impulses in less than 40 ms, sufficient for complete recovery from a perturbation at the onset of swing phase. Such capability could insure […]
Understanding Batoid Propulsion Through Artificial Structures
Meeting Abstract 65.4 Thursday, Jan. 6 Understanding Batoid Propulsion Through Artificial Structures KEMP, T*; BART-SMITH, H; MOORED, K; University of Virginia; University of Virginia; Princeton University tk4b@virginia.edu The manta ray (Manta birostris) is known for its swimming maneuverability and it is thought that these animals have a high long range cruising efficiency; both of these qualities are […]
The effects of head shape on drag and lift during subsurface sand-swimming
Meeting Abstract 65.2 Thursday, Jan. 6 The effects of head shape on drag and lift during subsurface sand-swimming MALADEN, RD*; DING, Y; UMBANHOWAR, PB; MASSE, A; GOLDMAN, DI; Georgia Tech, Atlanta; Georgia Tech, Atlanta; Northwestern Univ., Illinois; Georgia Tech, Atlanta; Georgia Tech, Atlanta Dingyang@gatech.edu Morphological adaptations such as a sharp wedge-shaped head are hypothesized to reduce sand-swimming […]

Importance of wrist rotation for high performance terrestrial locomotion of a sea turtle inspired physical model
Meeting Abstract 65.3 Thursday, Jan. 6 Importance of wrist rotation for high performance terrestrial locomotion of a sea turtle inspired physical model MAZOUCHOVA, N.*; UMBANHOWER, P.; GOLDMAN, D.I.; Georgia Institute of Technology; Northwestern University; Georgia Institute of Technology nmazouch@gatech.edu To reach the ocean after hatching, juvenile sea turtles use their flippers to traverse a beach environment typically […]
Ground Effects on Undulating Fins Robotic Modeling of Stingray Locomotion
Meeting Abstract 65.5 Thursday, Jan. 6 Ground Effects on Undulating Fins: Robotic Modeling of Stingray Locomotion BLEVINS, E.L.*; LAUDER, G.V.; Harvard University; Harvard University eblevins@fas.harvard.edu Benthic fish are specialized for life at the boundary between the fluid and solid world. Many species use the substrate for a direct boost to propulsion, from pelvic fin punting by skates […]
Biorobotic analysis of the functional significance of fish tail shapes
Meeting Abstract 65.6 Thursday, Jan. 6 Biorobotic analysis of the functional significance of fish tail shapes LAUDER, George*; WITT, Chuck; ANDERSON, Erik; Harvard Univ.; Grove City College; Grove City College glauder@oeb.harvard.edu Fish vary greatly in tail shape. The homocercal (symmetrical) shape characteristic of most teleost fishes, and the heterocercal (asymmetrical) shape that is present in most shark […]
