Abstract
The purpose of this study was to assess the measurement agreement between a low-cost system (phone camera) and a reference optoelectronic system, to measure spatiotemporal variables that may be related to wheelchair racing performance: acceleration phase time, push time, backswing time, and maximal elbow height. Three regular wheelchair racers propelled at maximal velocity on a training roller. The temporal variables had a low disagreement between both systems (bias ± 1.96 std of less than 0.01 s ± 0.02 s), while for the maximal elbow height, a higher disagreement of 0.020 m ± 0.038 m was observed. Future improvements are required especially to measure the maximal elbow height. This method may have long term benefits both for the athletes and research, by including more wheelchair racing athletes in future biomechanics studies.
