  • Zepp tennis analyzer

    Has anyone checked out this new Zepp stroke analyzer yet? Looks interesting, but I would not spend $150 for it until I see some feedback from the great players and coaches on this site.

    Thanks,
    Dave

      Haven't tried, and I'm in neither category you site <g> but you piqued my curiosity, so I looked. The sensor goes on the butt cap. First, I'd have a hard time feeling comfortable holding the racket with part of the bracket under my palm.

      Second, accelerometers have gotten awfully good, but I'm skeptical how well it will convey your wrist attitude relative to the arm swing by simply measuring movement of the butt cap (if the attitude of the butt cap changes is that because the arm moved, or only the wrist, or both? how would it possibly know? Does it instead simply track the movement of the butt cap, which would not be tremendously useful). How does it know if you arm is bent or straight? Near your body or extended? Am I missing something? Let us all know if you try it and good luck!

      • I agree with your assessment. I sure as heck am not buying it unless I learn more about it with some reviews of it in action. Your points are in my opinion very well taken, especially the idea of it interfering with holding the racquet with an object stuck on the butt cap.
        Hopefully someone else will chime in with either direct experience or an opinion.

        • I am in the dark here guys. Didn't know it existed.

          This is the description:

          Zepp Tennis features the ability to track the amount of forehands, backhands, serves and smashes you hit, how much power you generate with each stroke, how many topspin, slice and flat shots you hit, your trends for an entire match or practice session, the total amount of time you spend on court and the active time you spend playing points and rallying.


          Not sure what this means though or how helpful some of it could be. How many topspin, slice, or flat shots doesn't sound like a measurement and how much "power" you generate is vague as well.

          • John, another racket drop question on the serve. What do you think of the concept to think you are hitting up instead of hitting forward, to bring the racket lower? You know, the throwing the racket straight up in the air drill?

            • I love that drill. Do it with a tennis ball, an American football, and an old racket--should be ok on your red clay...

                I am not sure how this forum works or how I follow up, but here goes. It might be interesting to have a fast pitch softball coach talk about generating speed and see what similarities there are to forehand. Also in looking at Pujols swing you can see how his rear hand and elbow are in a situation very similar to a pro forehand like Agassi. Also his elbow drops into the unit turn position in a similar fashion. It would be interesting to know if they (Pujols and Agassi) are exerting forces the same way.

                • Somewhere there is an expert...any suggestions?

                  • John, how important are the "jutting buttocks" on the serve? i.e., the upper torso jackknifing after impact? Is it essential? Thanks, Phil

                    Comment


                    • I would say it's important to minimize this. To me the best servers land on balance with the torso and spin straight up and down. If it happens it is a reaction to the force of the swing. Trying to make it happen will drag the head and racket down.

                      • Thank you John. I value your insights. P.S. I really feel much better with my first attempts as a platform stance. It is not a very wide stance yet, but at least it is stable.

                        I am using Ubersense, and made these clips of my serve. Still working on my racket drop...

                        • Looks pretty good. I always felt a lot better coil and leg drive with the platform personally. the pinpoint you are over there to right flailing... I still think that compressed backswing is the problem with the racket drop.

                          • Thanks John, I will work on the bigger backswing next.... (might help my racket drop too...)

                            • That's what I think. Try bringing that elbow really forward and high and then just let gravity take it.

                              • John,
                                Have been trying to alter my backswing on the serve as you suggested. Strange thing is I do the movement in front of the mirror, think I have the "feel", go on court, think I am doing it, video record it, and, low and behold, I am still doing the old movement. Reprogramming is not so easy. Any tips?
                                Thanks, Phil
