Figure 3.

Spine rotation graph (pelvis – torso differential) The X‐axis measures time in seconds from address to follow‐through. The black vertical lines sequentially represent (from left to right): address, top, impact, and follow‐through. The Y‐axis represents degrees of thoracic spine rotation relative to the pelvis in degrees. The gray horizontal line is the zero baseline representing no rotation. The Y‐axis positive values represent rotation toward the target, negative values represent rotation away from the target.
