Six inertial measurement unit-based components describe wheelchair mobility performance during wheelchair tennis matches

Abstract The aim of this explorative study was to determine the key inertial measurement unit-based wheelchair mobility performance components during a tennis match. A total 64 matches were played by 15 players (6 women, 5 men, 4 juniors). All individual wheelchairs instrumented with units, two on axes wheels and one frame. 48 potentially relevant outcome variables initially extracted from sensor signals, based previous sports research input experts (coaches, embedded scientists). principal component analysis used reduce set most outcomes for mobility. Results showed that in can be described six components: rotations racket side (1) curves (2) turns; (3) linear accelerations; (4) non-racket turns (5) curves; finally, (6) velocities. One or per selected allow an easier interpretation results. These adequately describe aspect match monitored training.
