In the context of pelvic adjustments, rotation of the horse's pelvis most directly causes which pelvic movement in the rider?

• A. Pelvic rotation
• B. Posterior pelvic tilt
• C. Anterior pelvic tilt
• D. Pelvic lateral tilt

Answer: (C)

When the horse’s pelvis rotates, the rider’s pelvis is driven to adjust in a way that preserves balance on the moving seat. The most direct response is an anterior tilt of the rider’s pelvis—think of the pelvis tipping forward so the front of the pelvis drops and the lower spine gains a bit more curve. This forward tilt aligns with the shift of weight that comes from the horse’s rotational movement and helps the rider maintain an upright, balanced posture on the saddle.

Posterior pelvic tilt would require the rider’s pelvis to tilt backward, which isn’t the immediate pattern produced by the horse’s pelvis rotating. Lateral tilt involves a side-to-side tilt, which isn’t the primary response to a transverse rotation of the horse. Pelvic rotation of the rider is a separate motion in the same region, but the direct consequence of the horse’s pelvic rotation tends to be forward tipping of the pelvis.
