Meeting Abstract 115.3  Monday, Jan. 7  Compensations for increased rotational inertia during human cutting turns JINDRICH, DL*; QIAO, M; California State University, San Marcos; Arizona State University djindrich@csusm.edu Locomotion in a complex environment is seldom steady-state, but the mechanisms used by animals to power and control unsteady locomotion (stability and maneuverability) are not well understood. We used […]

Meeting Abstract 115.5  Monday, Jan. 7  Collision-based analysis of human walking versus running with and without additional vertical loading LEE, D/V*; COMANESCU, T/N; BERTRAM, J/EA; University of Nevada Las Vegas; University of Nevada Las Vegas; University of Calgary david.lee@unlv.edu Collision-based analysis quantifies geometrically and energetically the interaction between the center of mass (CoM) and the environment. This […]

Meeting Abstract 115.2  Monday, Jan. 7  Can we improve a footballer’s kicking performance using optimisation theory? HUNTER, A*; WILSON, R S; The University of Queensland; The University of Queensland r.wilson@uq.edu.au How much effort should an individual use when executing a physical task? And how much effort should one use if a physical task or skill relies on […]

Meeting Abstract 114.3  Monday, Jan. 7  Wings versus legs: mechanistic underpinnings of variation in locomotor strategies among birds HEERS, A M*; DIAL, K P; University of Montana; University of Montana ashmheers@gmail.com Among the 10,000 species of living birds and their extinct dinosaurian ancestors, relative musculoskeletal investment in wings versus legs is highly diverse, varying both across species […]

Meeting Abstract 114.2  Monday, Jan. 7  Continuous metrics for classification of bipedal gaits and predictions of gait transition fine structure in turkeys WILSHIN, SD*; DALEY, MA; Royal Veterinary College; Royal Veterinary College swilshin@rvc.ac.uk An accurate method for differentiating walking and running bipedal gaits is presented and applied to experimental data from turkeys. It is known that bipedal […]

Meeting Abstract 113.4  Monday, Jan. 7  Gut microbes facilitate consumption of toxic diets by herbivores KOHL, K.D.*; WEISS, R.B.; DALE, C.; DEARING, M.D.; Univ of Utah; Univ. of Utah; Univ of Utah; Univ of Utah kkohl78@gmail.com For decades, ecologists have hypothesized that herbivorous mammals might host beneficial microbes that facilitate the ingestion of diets containing toxic plant […]

Meeting Abstract 113.1  Monday, Jan. 7  Estrogens and Plants EDWARDS, TM; Louisiana Tech University tedwards@latech.edu Our lab has shown that estrogenicity in soybeans varies among plant organs, and changes across the season as plants mature, and respond to seasonal environmental change. Estrogenicity of plant tissues comes from “phytoestrogens” – lignans, coumestans, and especially flavonoids. These plant molecules […]
