Visualize the racket face must be squarely open at contact point?
Hit the ball (clock face) from 7 to 1?
Intent to align body, shoulder in a certain way?
Visualizing ball contact -
Experiment - I have found just using my hand and no racket that if I visualize the impact orientation that I want and simulate a service/similar motion to impact, the hand can reproducibly impact at the desired angle after just a few practice tries. For example, stand and imagine that you are to hit a ball and want to hit the back square on or at some other angle. You then practice and in a few tries the amazing system seems to be doing it very
accurately. The natural visualization system is very capable. However, I'm not doing the full and free rotation with a racket as on the serve.
Knowing exactly where I want to impact with the racket for a serve is much more difficult. I don't trust my interpretation of the simple descriptions, for example, the '1 to 7' o'clock' path (kick serve). The stroke for the kick serve seems much more complicated than the '1 to 7' or similar description.
Believe this to be a kick serve.
How do I visualize this motion as I serve looking up at some angle? I've decided not to practice until I better understand. The face of the racket is really changing and how the server would perceive the racket face orientation in not clear. Is it squarely across the back of the ball or hitting the top half of the ball due to path and racket face rotation? Does Stosur see her racket face as traveling 1 to 7?
This motion seems simpler and the racket vertical orientation at impact is shown. Serve type unknown.
However, video camera views from the side or behind always show only two dimensions and never the direction toward or away from the camera. It is easy to misinterpret 3D object locations using 2D video.
To complicate things, I'm not sure that the pros look at the ball at impact for the serve. If I'm looking at the ball at impact have I screwed up my body position or motion? See videos above at impact. See Reply #9.
In serving during a match I abbreviate or leave out components of the service motion. Very often I'm not using the full edge-on racket orientation. I sometimes notice and change it and see an immediate pace increase on the serve.
The comments have been very helpful. The rkelley and SystemicAnomaly comments bring home the point that the WTE can precede the straight arm step.
I have not had a mental picture of supination during the serve or noticed it very much in videos. Maybe I've had more WTE than I thought in most of my serves and early supination might play a part. ?
