    Mystery of kick serve swing path

    What is to be executed? I have mentioned the 13-15 degrees closed racket many times and there have been few comments from forum readers. I have not seen it discussed in other places except in Technical Tennis indirectly. Do you think the OP's beliefs about how closed the racket face is at...

    The meanings of word descriptions of tennis strokes are the subject of many threads, 50%? You can search back to the beginning of TT and see very similar threads as many posters have various undefined tennis terms to use in very similar threads. See the thread Junior Twist Serve. The OP's...

    How do you prevent over rotation on serve?

    Video post #17. In the video there are at least two serves before 1:00, 14 sec & 25 sec that I'd say are a WT based on some blurry racket images, strings more facing to the sky. That's my interpretation of a blurry racket. See racket silhouetted against fence in 14 & 25. Looks likely WT to me...

    How do you prevent over rotation on serve?

    I don't get a clear picture from your word description. But there are some very interesting things to be seen in the overhead two frames at impact. Go to the frame of impact in the Salazar serve overhead view. Go full screen. Now use the period & comma keys to go back and forth, back and...

    How do you prevent over rotation on serve?

    The viewed-from-above clockwise rotation of ISR lasts about 25 milliseconds, start to impact. My guess is that the counter clockwise body rotation has slowed or stopped when the very rapid ISR occurs. ? Let's see for Frank Salazar's slice serve from FYB footage. Single frame on Youtube using...

    How do you prevent over rotation on serve?

    That looks like a Waiter's Tray serve. Maybe "over rotation" is often associated with the WT?

    9-21-20 Serves

    The frame rate is slow so that only about two frames are available to show the approach to the ball and there is too much motion blur. It looks as if your elbow is too bent for too long a time? Try to compare this point to serves in this video. For single frame use the period & comma keys...

    Tennis in post-World Cup city

    Single frame use Period & Comma keys. To select YT video always use Alt + Left Mouse Click, otherwise the video starts playing. Compare separation and all other sub-motions. In many forehands, Djokovic shows a lot of separation and his range of motion may be too much for many players...

    How do you prevent over rotation on serve?

    If anyone has a video of 'over rotation' please post it. For the serve as viewed from above, the line between the shoulders rotates counter clockwise and the rotation at the wrist from ISR rotates clockwise. So considering those two rotations, fast rotation of the body subtracts from the...

    Who should be sascha zverev's serve coach?

    For a kick serve 1) The racket should be rising during impact. Look at the angle between the forearm and racket shaft and also the racket's highest point reached with view as shown in Dragy's Isner picture, but make certain it is a high speed video so that the frame of impact is known. Behind...

    I totally don't get pronation and how to serve.

    In post #33 in the video at 9:47. Click on the video and the 4 frames of the pro servers soon appear. I quoted what was said and discussed the 4 frames in detail in post #33.

    "Can you stop now? the orientation of the pros at the moment of contact and you will see that they are all at roughly 45 degrees at the moment of contact." (I cannot hear the beginning of what is said in the video. Can anyone else?) Stop the video on 9:47. What is oriented 45 degrees to...

    General help improving consistency of ground strokes

    This long thread has specific video observations on the one hand backhand. Read post #1, post #51 and then the posts about the observations. A theme of the thread is that most of the best backhands have these motions in their strokes. One of the main points is that the shoulder joint at first...

    I totally don't get pronation and how to serve.

    What use did you make of high speed video of your serve? Look for the elbow to be bent at impact and other differences that might be related. Golfer's Elbow is an tear in the tendon. If so you should not stress it, especially with more tennis. See Tendon Injury Nuthouse, especially post #1...

    The Frankenstein Serve

    The tennis serve is often thought of in terms of a few words. Examples: 'Hit up and out.' 'Hit from 7 to 1 o'clock.' 'Relax the arm' 'Face to the side' '....?..... vertical' 'fully pronate' What are some of your words?

    Am I doing the WTE?

    I have not studied that part of the serve much for racket face angle or after impact. I emphasize working back from impact and the motions that nearly all the high level servers use. WT before racket drop? WT is a serve technique. I don't know the statistics of the racket face angles for...

    Am I doing the WTE?

    It does not look right to me. I suggested a close up video showing your arm especially to see ISR clearly. Have you compared frame-by-frame and listed all differences as described in post #22? If you compare your impact frame to impact in the video above you, what differences can you see?

    Two hander vs one hander for new player.

    You have a very good & effective looking backhand. But you use more shoulder joint motion and less uppermost body turn for racket head speed. This thread discusses video observations that I believe characterize the best one hand backhand technique. Federer is not included in the technique...

    Am I doing the WTE?

    I find the Big L Position (the arm and racket form a big upside down "L") then I look at the motion to the ball as starting when ISR starts. I look at the racket to be about "edge on to the ball" for an instant at the Big L Position. I believe that many tennis coaches and instructors do the...

    Am I doing the WTE?

    Can you see ".....advanced players keep the racquet on edge longer " ? I see no "keep the racquet on edge longer". I attribute this rare overhead view to ISR with rotational acceleration. I hardly ever consider the follow through because it can vary after impact. From start of ISR to impact...
