Simply working on your swing speed can have a cumulative effect on your performance; but without proper swing mechanics, it may do more harm than good. Fine-tuning your swing based on stability, control and flow will maximize your speed, accuracy and distance. (Review How to Fix Golf Swing Muscle Imbalances.)

In 2005, Auckland University conducted a study that examined the impact of swing biomechanics on distance and accuracy on the course. (You can read the entire study here.)

Swing Study Findings

• For your golf swing to be most effective, your core needs to do all the rotating to keep your shoulders in line with the ball.
• To get the most distance from your swing, you need to create a lot of Ground Reaction Force (GRF). GRF is the spring that you receive from the ground between gravity and the force you exert. The greater the GRF, the longer the ball travels.
• You need to keep your lower half stable from start to finish of your golf swing and increase your stretch in the upper half to develop a powerfully accurate shot.
• It doesn’t hurt to incorporate some strength training to increase the X factor—the rotation of shoulders to hips—against the GRF. Building strong legs, core, shoulders, back and chest will greatly increase muscular power, leading to a quicker stretch in the upswing.
