About Richard Marsh
My major research interest is the in vivo function of skeletal muscle during movement. More specifically my current research investigates the mechanical function of skeletal muscle in vivo and the links between mechanical function and energy use. I use an integrative approach that combines organismal measures of energetics, kinematics, and kinetics with more invasive procedures that monitor in vivo the length, activity, and energy use of individual muscles in freely moving animals. His current research focuses primarily on walking and running, but past work has included studies of swimming, flying, and jumping. Major equipment items in my laboratory include a digital high-speed video system, a small-animal force plate, respirometry equipment, a 14 channel electromyography system, and a multichannel sonomicrometer system. Experiments have been conducted with numerous species of animals, and work has begun on human subjects.
