Validation of Wearable Sensors during Team Sport-Specific Movements in Indoor Environments.

ABSTRACT: The aim of this study was to determine possible influences, including data processing and sport-specific demands, on the validity of acceleration measures by an inertial measurement unit (IMU) in indoor environments. IMU outputs were compared to a three-dimensional (3D) motion analysis (MA) system and processed with two sensor fusion algorithms (Kalman filter, KF; Complementary filter, CF) at temporal resolutions of 100, 10, and 5 Hz. Athletes performed six team sport-specific movements whilst wearing a single IMU. Mean and peak acceleration magnitudes were analyzed. Over all trials (n = 1093), KF data overestimated MA resultant acceleration by 0.42 ± 0.31 m∙s-2 for mean and 4.18 ± 3.68 m∙s-2 for peak values, while CF processing showed errors of up to 0.57 ± 0.41 m∙s-2 and -2.31 ± 2.25 m∙s
