A kinematic analysis of jumping technique in elite Korean teeterboard athletes: a case-study.

Korean teeterboard is a circus discipline that consists of a board pivoted at its centre upon which two acrobats are catapulted in turn performing acrobatic jumps. This paper presents one of the first studies that focuses on investigating the factors that contribute to jump height in Korean teeterboard. A total of 120 jumps were recorded from two acrobats using motion capture.

Learned Overweight Internal Model Can Be Activated to Maintain Equilibrium When Tactile Cues Are Uncertain: Evidence From Cortical and Behavioral Approaches.

Human adaptive behavior in sensorimotor control is aimed to increase the confidence in feedforward mechanisms when sensory afferents are uncertain. It is thought that these feedforward mechanisms rely on predictions from internal models. We investigate whether the brain uses an internal model of physical laws (gravitational and inertial forces) to help estimate body equilibrium when tactile inputs from the foot sole are depressed by carrying extra weight.
