Engineering a Better Golf Swing

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) November 14, 2010 -- The golf course is one of the best places to do business, and from personal experience, golf is one of the most relaxing ways to spend four hours. The basis of any individual’s game, the swing, is one of the most complex and difficult motions in sports. This means that the hours people spend every week during the summer trying to perfect their golf swings, might be spent in vain.

The odds of stumbling onto the perfect golf swing have to be similar to those for getting a hole in one. Hitting a golf ball, as far as the pros, depends on the collaboration of many different motions simultaneously; timing of the wrists, squaring of the clubface, and the angle of the swing plane are just a few. However, without sufficient club head velocity, no matter how straight you hit it, the ball will not go 300 yards. So the question is, how do you increase your wholesale golf club (wholesale golf clubs = http://www.enjoymygolf.com )head velocity? If going by feel hasn’t worked, maybe it’s time to use our engineering skills to find a better golf swing.

Dr. Steven Nesbit, P.E. and I have spent the last seven months at Lafayette College in Easton, PA trying to find the answer to this question of maximizing velocity. The answer lies in a characteristic of the golf swing that past biomechanical studies have assumed away: the radius. Cochran and Stobbs (1969) initially proposed a “double pendulum” model, where the first link of the pendulum represents a rigid connection between a fixed point of rotation and the grip point of the club. Meanwhile the second link represents the TaylorMade R9 Superdeep TP Driver （TaylorMade R9 Superdeep TP Driver = http://www.enjoymygolf.com/goods.php?id=25 ） itself, as an accurate approximation of the golf swing. This model assumes that the path traced by the position of the grip point during the downswing will have a fixed radius and center of curvature. The simplicity of this model and the computational ease that it ensured led to its employment by several researchers who analyzed other aspects of the swing. However, a few years ago Dr. Nesbit (2005) used a full body modeling approach and noted that the hub path of the TaylorMade R9 Superdeep TP Driver （TaylorMade R9 Superdeep TP Driver = http://www.enjoymygolf.com/goods.php?id=25 ） swing, in other words, the path traced out by the hands through the downswing, was in fact non-circular and specifically that the radius seemed to decrease from the start of the backswing through impact. He also noted that the ratio of the radius of the hub path at the start of the back swing to impact has a strong correlation to club head velocity. This means that the radius cannot be assumed as constant through the downswing and that in all likelihood, the hub path has a definite affect on a golfer’s club head velocity at impact.

As you envision your own golf game steadily improving thanks to the application of a little bit of your engineering knowledge, you might wonder what we’ve found out so far. The answer is that we have discovered that the radius of a golf swing is not constant and the center of curvature is almost constantly changing. We have determined that there are relationships that exist between the changing radius and club head velocity, applied force, torque, work, and power, and that even a small change in hub path and wrist trajectory values can increase club head velocity. Even for a scratch (0 handicap) golfer, a slight manipulation of his hub path, while keeping the wrist trajectory the same as in his typical swing, can result in increased TaylorMade R9 Superdeep TP Driver （TaylorMade R9 Superdeep TP Driver = http://www.enjoymygolf.com/goods.php?id=25 ） club head velocity. Radius clearly plays an important role in the golf swing. Now you know; to hit a golf ball as far as the pros, all you need to do is change your hub radius.
