Golf - Why Is It That a Harder Swing Usually Results in Less Distance?
A harder swing has less of a chance to hit the “sweet spot” on your clubface. An easy swing that hits the sweet spot will send the ball farther than a hard swing that misses the sweet spot.
A hard swing may cause improper weight shifting, which may reduce your clubhead speed. Proper weight shift from the top of the backswing starts going from the back foot to the front foot before the downswing begins, setting up the power of a whip without extra effort.
Clubhead speed at impact is the sum of arm swing and wrist snap. A hard swing usually starts the wrist action too soon when the downswing begins, so there is no more acceleration added from the wrist by the time the clubhead gets to the ball, resulting an “all arms” swing and slower clubhead speed. For maximum distance, you must save the wrist action until just before impact. This is best demonstrated with a ping pong ball and paddle. How far can you hit the ping pong ball with an all-arms swing compared to using your wrist? Watch the slow motion replays of the pros on TV, and you will see the wrist snap is held back until the last possible instant. That is why most of the pros may look like they are swinging very easy, but they still generate a lot of clubhead speed with that last-second wrist snap. (see www.geocities.com/golfwithjoey)
