In the context of a golf swing, which type of rotation is deemed more important?

In the context of a golf swing, internal rotation is deemed more important because it plays a crucial role in the proper mechanics of the swing. During the backswing and follow-through, internal rotation helps to ensure that the shoulder and hip joints are positioned correctly to generate the necessary power and maintain balance.

When the lead arm internally rotates, it allows for a fuller range of motion in the shoulder, facilitating a more effective swing path. This rotation helps keep the club on the correct plane as the golfer transitions from the backswing to the downswing. Moreover, internal rotation contributes to the proper sequence of muscle activation which is essential for generating speed and accuracy in the swing.

While other types of rotation, such as external or lateral rotation, have their roles in different movements, the internal rotation specifically enhances the biomechanical efficiency related to the golf swing and contributes to overall performance on the course.
