The effects of rear-wheel camber on the mechanical parameters produced during the wheelchair sprinting of handibasketball athletes
be taken into account in the search for optimal regulation of a power wheelchairs
and medical scooters. This study examined the effects of different rear-wheel camber (9 degrees , 12 degrees and 15 degrees )-today used mainly in the handibasket championship-on the various kinetic and kinematic parameters of the propulsion cycle. Eight males, all players in the French handibasket championship, were asked to participate in this study. They performed three 8 s maximal sprints as measured by a wheelchair ergometer, 9 degrees , 12 degrees , and 15 degrees of rear-wheel camber. The results of our study show that residual torque increases in proportion to the increase in wheel camber. This could explain other study results, which show a decrease in mean velocity and an increase in both power output and time of the propelling phase, in relation to the wheel camber. These results should provide the information necessary for optimal wheelchair regulation.
