TABLE 3.
Mean R 2 (coefficient of multiple determination) and standard deviation (S.D.) between the IMU‐ and MOCAP‐based lateral flexion, axial rotation, and flexion/extension angles for the dynamic sports motion, anatomical trunk motion, lateral flexion, axial rotation, and flexion/extension trials and for all trials (n = 196).
