Note: The total time is calculated assuming 5 repetitions. If fewer than 5 repetitions are detected, the average time per repetition is calculated and then multiplied by 5. Trunk flexion is determined by the forward trunk lean compared to the vertical axis of the camera frame. Trunk flexion and acceleration are reported as the average of the maximum flexion and acceleration over all cycles.
