In this talk I will provide brief snapshots into a series of studies exploring effort minimization during legged locomotion including: 1) the generality of locomotor energetic optimization across bipedal species; 2) optimization of muscle efficiency; 3) effort minimization in human gait transitions; 4) developmental plasticity of locomotor energetics; and 5) recent human gait experiments aimed at teasing out the relative importance of energy vs. stability optimization and global (organismal) vs. local (muscle) effort.\u0026nbsp; These topics are intended as a background to discuss and debate the question of effort minimization as a design principal in legged locomotion (and more broadly, animal motor coordination).\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EAbout the Speaker\u003C\/strong\u003E\u003Cbr \/\u003E\r\nDr. Rubenson is an Associate Professor in the Biomechanics Laboratory (Department of Kinesiology) and directs the Muscle Function +\u0026nbsp;Locomotion Lab, Penn State University. Rubenson\u0026rsquo;s work is dedicated to understanding the biomechanics and energetics of legged locomotion.\u0026nbsp; His group is interested in\u0026nbsp;mechanisms of locomotor adaptation and optimization, and, in particular, the biomechanical determinants of locomotor energy cost.\u0026nbsp;Rubenson\u0026rsquo;s work primarily focuses on basic\u0026nbsp;research both in humans and using a comparative approach, and more recently includes\u0026nbsp;clinical- and pre-clinical studies.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EPhysiology Brownbag Seminars\u003C\/strong\u003E\u003Cbr \/\u003E\r\nThe Physiology Group in the School of Biological Sciences hosts Brownbag Lunchtime Seminars twice a month on Wednesdays at noon in room 1253 of the Applied Physiology Building located at 555 14th Street NW, Atlanta, GA 30318.
