Meeting Abstract

73.2  Tuesday, Jan. 6  Actuation and compliance of goat foreleg during landing jumps YOO, E/H*; LEE, D/V; BIEWENER, A/A; Harvard University; University of Nevada Las Vegas; Harvard University eyoo@oeb.harvard.edu

Using high-speed video and force plates, we collected foreleg kinematics and ground reaction force data in three adult male African Pygmy goats (Capra hircus) performing landing jumps from a 1.3 meter platform. External moments and work were calculated for elbow, wrist, and metacarpophalangeal joints. We then model each joint as a serial actuator and spring and calculate the spring constant that minimizes total actuator work using experimental joint moment and joint angle data. We expect calculated spring/actuator work data from our model to be consistent with differences observed in muscle-tendon anatomy of proximal vs distal joints.
