BRAMBLE, D.M.*; LIEBERMAN, D.E.; DALEY, M.A.: Mechanics of Head-Neck Stabilization in Running Humans: Implications for Hominid Evolution Adequate head-neck stabilization ought to be vital to any running mammal but the phenomenon has been little studied. We investigated the mechanical basis of cranio-cervical stability in humans during treadmill walking and running. Quantitative measures of head-neck and […]

THOMPSON,E.N.*; BIKNEVICIUS,A.R.: A Biomechanical Analysis of the Development of the Masticatory Apparatus of Monodelphis domestica While several studies have found differences in the craniofacial configurations of juvenile and adult mammals, how these differences affect masticatory process has been poorly explored. The present study evaluates the masticatory apparatus in an ontogenetic series of short-tailed opossums(Monodelphis domestica) […]

Demes, B.*; Chiu, J.; Truong, C.; Qin, Y.; Larson, S.: The role of the primate fibula in weight-bearing of the leg Among mammals, primates have relatively robust fibulae. We investigated the role of the primate fibula in weight-bearing in an in vitro study of the deformation of the two leg bones in a chimpanzee, baboon […]

DUDEK, D.M.*; FULL, R.J.: Spring-like behavior of the legs of running insects The dynamics of many terrestrial organisms during running are similar to those of a bouncing spring-mass system. This observation has led to the search for spring-like behavior in the tendons of mammals. The dynamics of running cockroaches have been modeled as a spring-mass […]

Meijer, K*; Libby, T.M.; Full, R.J.: Passive stability provided by the musculo-skeletal properties of an insect leg. Cockroaches have an amazing ability to run over rough terrain. It has been hypothesized that their ability to perform stable locomotion in unstructured environments is facilitated by the mechanical properties of their muscles and exoskeleton. To investigate the […]

COX, D.E.*; BERTRAM, J.E.A.: Hypothesis testing as a lab exercise: a simple walking study This paper describes a laboratory exercise designed to provide students with experience testing a hypothesis by systematically isolating and controlling determinant variables. The study involves the analysis of walking and is performed by the students on a subject from within their […]

Carello, C. A.*; Scheunemann, T. L.; Heitmann, D. M.: How body size affects the metabolic efficiency and lower limb joint kinematics of quail running on an incline The majority of studies dealing with bipedal locomotion on varying surface grades have focused on humans. Thus, little is known about the relationship between body mass and efficiency […]

HOYT, D.F.*; WICKLER, S.J.; COGGER, E.A.; GOEHRING, M.E: A Reexamination Of The Trot-Gallop Transition: Insights From The Study Of Locomotion On An Incline. Previous workers concluded that forces trigger the trot-gallop (T-G) transition because it occurred at a lower speed when ponies carried a load and, at the T-G speed, the metabolic rate was higher […]

EIDIETIS, L.*; WEBB, P.W.; FORRESTER, T.L.: The abilities of two morphologically different fishes to counteract rolling disturbances We increased rolling moments and decreased negative metacentric heights of spiny rayed Lepomis macrochirus (bluegill) and soft rayed Semotilus atromaculotus (creek chub) by attaching weights and floats which, together, were neutrally buoyant. Weight and buoyant force were normalized […]

ELLERBY, D.J.*; SPIERTS, I.S.Y.; ALTRINGHAM, J.D.: Slow muscle power output of yellow- and silver-phase European eels (Anguilla anguilla, L.): changes in muscle performance prior to migration The European eel (Anguilla anguilla, L.) has a complex life cycle involving a lengthy spawning migration. The differences in the locomotory demands on different life history stages are considerable. […]
