FIGURE 2.

The IMU‐based (solid) and MOCAP‐based (dotted) trunk angles over time. The columns represent the four dynamic sports motions: throw (participant 1); baseball swing (participant 10); golf swing (participant 9); tennis serve (participant 4). The rows represent the three trunk angles in degrees: lateral flexion (blue; positive and negative are left and right, respectively); axial rotation (green; positive and negative are right and left, respectively); flexion extension (red; positive and negative are extension and flexion, respectively)
