  1. All values are expressed as mean ± standard deviations per person. The recordings “ST Full Recording” and “DT Full Recording” are the original non-segmented recordings from the entire single-task or dual-task visits. The recordings “ST-Control”, “ST-Fatigue”, “DT-Control” and “DT-Fatigue” are recording segments of only the 6-minute walks under the respective conditions. The recordings “ST Fatigue Protocol” and “DT Fatigue Protocol” are recording segments of only the sit-to-stand fatigue protocol. Acc.: acceleration, Gyro.: angular velocity measured by the gyroscope.
