Abstract : The present study is investigating the basic neuromotor coordination mechanisms involved in a rapid elbow flexion movement, and in developing mathematical models to explain the interaction of these basic neuromotor coordinations with the biomechanical parameters of movement speed. Speed of movement is being assessed in a biomechanics mode via displacement, velocity, acceleration, point of inflection between acceleration and deceleration, and the total time of an elbow flexion movement. Electromyographic analysis techniques are used to monitor the sequential timing of agonist and antagonist muscle activity. The mathematical modelling effort incorporates the biomechanical parameters into an interface with the neurophysiological parameters involving the central and peripheral nervous systems, and then extends the interface to include viscoelastic properties of the muscle, activation delays, and neuronal pools.
