Wheelchair mobility performance is an important aspect in most wheelchair court sports, commonly measured with an indoor tracking system or wheelchair bound inertial sensors. Both methods provide key performance outcomes regarding speed. In this study, we compared speed profiles of both methods to gain insight in the level of agreement. Data were obtained from 5 players during 6x 10 min. of wheelchair basketball match play. Both systems provide similar outcomes regarding distance covered and average speed. Due to differences in sample frequency and reference position on the wheelchair (for speed calculation), minor differences show at low speeds (<2.5 m/s). Since both systems provide complementary features, a hybrid solution as proved feasible in this study, could possibly serve as the new standard for mobility performance measurement in court sports.
