Golf club head lag = tennis serve?

[hihihi8402]

In golf, the club is at a 90 degree angle to the arms almost until the hands are over the ball on the downswing. Then the wrists "release" and the club head whips through the ball. And, its generally taught that the more "lag" you have the more power. I watched a slow motion video of pete sampres serve and it looks like at the top of his serve his racquet is at a 90 degree angle to hit arm and then his wrist does a similar release and whips through the ball. Andy Roddick also does this. How come no one ever talks about this? Is this something that we (people who are not good at tennis) should try to do?

what you are seeing is pronation and it is the most important aspect of hitting a serve correctly with power. yes, you should be doing it, and if you do it right, you won't mess up your wrist

basically you drag the racket up, "lagging" as you put it, until your arm reaches full extension. then, you let the momentum of the racket snap it up into the contact zone and roll to the other side of your body

Keep the wrist relaxed throughout the motion. The racquet will be rotating around with the serve motion. When the racquet is at its lowest point behind the shoudler your arm will thrust upward toward the ball. This sudden change in direction will allow the wrist to "layback" since it is real relaxed. Then as the arm extends and slows down, the energy is tranferred to the relaxed wrist and the wrist comes forward which brings the racquet into the ball and through.

If you wanted to look at it more in depth, there are actually two parts lagging. When you start the forward swing on the serve, you should lead with your elbow, causing your forearm to lag behind. Then, you keep a loose wrist, causing your racket to lag. Once your upper arm reaches its peak, it causes the forearm to (I hesitate to say it, as I know it will be misinterpreted and debated) 'snap' forward. Once your elbow becomes straight, it will cause your wrist and racket head to also 'snap' through contact. None of this should be forced, but it is all a small part of what people refer to as the kinetic chain that ocurrs throughout the service motion.
