Hip rotation (Swing Analytics): What It Is & Why It Matters
In plain language, what does "Hip rotation" mean on my monitor or export?
Rotation of the pelvis around the vertical axis; same sign convention as upper body rotation (opening vs closing relative to ankle line).
Units: degrees
Why does this metric matter for ball flight, dispersion, or scoring?
The pelvis usually leads the kinematic sequence in transition. Timing and range here strongly influence torso and club delivery.
What is a typical or competitive range for this stat?
Varies with flexibility and foot flare; use stability of your baseline more than chasing tour averages.
What usually makes this number look bad or noisy in real rounds?
Big lateral motion with little rotation can look busy but never really turn—pair with separation (chest vs hips) traces.
What other metrics should I look at together with this one?
Upper body rotation, Chest vs hips separation, Peak clubhead speed
