You weren't dragging the racquet head loose as much as you probably do now, getting it more supine and then getting more room to pronate in.
But still, the angle of the wrist at contact determines the amount of flexion or ulnar/radial deviation.
More flexion gets very close to the pure "wrist snap" position. But it is not a pancake, waiter's tray "pure flexion" motion. It's angled and twists in to out, but also up and down by a high degree in the flat bomb serve. Think of a concave shaped flight path.
Every decent server supinates
Thats My Point. This is what the rest of us needs. I never Supinated before. I learned it and how to do it as well as teach it this year.
Even in my Video about the Serve I didnt know how to do it. Tell me Tim if you can see a difference.
Every decent server supinates before they pronate. The loop that happens just after trophy is supination. The face opens up "supine", or laying upwards at an angle at the top as it begins to loop before pronation phase, facing downwards.
But I am talking about how the wrist moves at the point of contact, just as the video focuses on. Does the wrist go more up and down, "flexion" or does it go more up and out, "radial to ulnar deviation".
It Doesnt Just represent the kick. I do this pronation thing he talks about but...i Supinate before.
I would say it is not either/or. I just think the video only presents the Fed kicker as the only example of the first scenario, "up and out", and then say there is no "wrist snap". Not always the case, given the photos I put up here.
Depends on the angle of the wrist at forward movement and at what degrees the shoulders open up toward the court. If the angle of the wrist is at a high beta angle, and the shoulders are more closed, you will get "up and out" motion of the kick serve. If the angle of the wrist is at a lower beta angle, and the shoulders more open, you will get more of the "up and down" motion of the so called "wrist snap" the old schoolers named of "wrist flexion".
Tim:are you proving the point or arguing it?
When the beta angle is 25 degrees, Fed hits more wrist flexion component. When the beta angle is 35 degrees, Fed hits more radial to ulnar deviation. This is a function of how turned his chest is to the net.
