RESEARCH ON THE BIOMECHANICAL PRINCIPLES OF UPPER LIMB WHIPLASH MOVEMENT
AbstractPURPOSE Upper limb throwing movements of male javelin athletes were analyzed with mathematical simulation to study the biomechanical principles of upper limb whiplash movements. RESULTS It was showed that the changes of the resultant muscular moments of the upper limb were quite different from that of the lower limb in whiplash movements. There was a great effect of the joint reaction force on the segment rotation, and the influence of the proximal segment motion on the distal segment motion could not be completely explained by the theory of “transfer of angular momentum” in upper limb whiplash movements.
