Meeting Abstract 19.4  Wednesday, Jan. 4  Individual locomotor strategies in degus (Octodon degu) – implication for biomechanical constraints on terrestrial substrates varying in orientation SCHMIDT, André ; Ohio University Heritage College of Osteopathic Medicine schmidta@ohio.edu During locomotion animals typically show individual preferences in their locomotor performance (e.g., protraction angle). Previous results suggest that these individual differences gain […]

Meeting Abstract 19.5  Wednesday, Jan. 4  Does the SLIP Model Apply During Inverted Running in Cockroaches? PARIKH, S.C.*; MARA, K.R.; HSIEH, S.T.; Temple University; Temple University; Temple Unviersity sachincp16@temple.edu Center of mass (COM) dynamics during upright locomotion is described by the spring loaded inverted pendulum (SLIP) model. According to this model, gravity pulls the COM towards the […]
