During the golf swing, an anterior tilt of the lower back is most likely to cause which outcome?

• A. Increased spinal angle stability
• B. Restricted torso rotation
• C. Greater trunk extension
• D. Improved acceleration

Answer: (B)

An anterior tilt of the lower back puts the lumbar spine into more extension, which changes how the spine and hips move together during the swing. When the lower back is tilted forward, end-range stiffness in the lumbar region reduces how much the torso can rotate. In the swing, efficient power comes from turning the torso around a relatively mobile spine; if that segment is stuck in extension, the torso’s rotational range is limited, so you end up with restricted torso rotation. This displacement of rotation tends to shift effort toward other parts (like the hips or arms) and can disrupt the smooth sequencing needed for a powerful, controlled swing. So the most likely outcome is a limitation in how much the torso can rotate.
