ABSTRACT
Wheelchair racing places high physical and physiological demands on the bodies of athletes and the interaction between the athlete and the wheelchair has been identified as an area of critical importance (Cooper, 1990). Developing mathematical models based upon laws and actual experience are ways of gaining further insight into the interaction of the athlete, chair and environment. Recent wheelchair modelling work has focused on the efficiency of the human-racing wheelchair interaction (Cooper, 1990; Hofstad and Patterson, 1994).
