The complexity of wheelchair sports provide the scientist with a unique challenge. There are two major components that contribute towards ‘wheeled sports’ performance, these are the athlete and the chair. It is the interaction of these two that enable wheelchair propulsion and the sporting movements required within a given sport. This presentation will provide an insight into the applied sport science research that has been provided to the Great Britain wheelchair athletes over the last decade. It will focus on four sports; wheelchair racing, wheelchair basketball, wheelchair tennis and wheelchair rugby. This session will discuss how sport scientists have worked with coaches and practitioners to help optimise training leading to a major competition through evidence base practise. As changes in different mechanical variables have been shown to affect the energy requirements of wheelchair propulsion then the first topic will discuss the concept of pushing economy and mechanical efficiency of wheelchair propulsion. The second topic will illustrate the concept of sports classification, and show how training volume ‘in terms of basketball shooting’ may need to be individually assigned. The third topic will show how technology assists the coaching process and finally future research within wheelchair team sports and chair configurations will be examined.
