The hip turn is a sequence, and in this example it starts with the arms.
The arms move first. The trunk and pelvis follow into rotation. Then the arms quickly counteract β driving the opposite direction β and the trunk stabilizes while the pelvis and lower half keep rotating faster than the upper half.
As the foot plants, the pelvis opens toward the new direction of travel. The trunk and arms follow, creating a whipping motion that pulls the athlete out of the turn and into a sprint.
One note: here the athlete is responding to an auditory cue. When the stimulus is visual, the sequence often starts higher up β the head and cervical spine may rotate first to locate the target, then the arms and the rest of the chain follow.
