A high sample rate, wireless instrumented wheel for measuring 3D pushrim kinetics of a racing wheelchair

In wheelchair racing, measuring pushrim kinetics such as propulsion forces and moments is paramount for improving performance preventing injuries. However, there currently no instrumented racing wheel that records 3D wirelessly at a high sample rate, which necessary accurately analysing biomechanics. this work, we present an measures 2500 Hz. Bidirectional wireless communication used to interface the through smart phone. The was tested with world-class athlete who propelled maximal acceleration speed on training roller. During acceleration, peak total force increased continuously from 186 N 484 while tangential constant 171 ± 15 N. At higher speeds, counterproductive measured during first 15% last 25% of push phase, peaking -78 This may be great value both coaches athletes help planning validating programs adaptations positioning. also has very potential further research biomechanics shoulder pathologies associated sport.
