Hi Resznotes,
Ok so I do think this is an important part of the backhand topspin shot. Coiling the bat back like this with the wrist allows you to generate more spin by releasing the wrist forwards and over the ball through the contact and also adds wrist acceleration to the shot too. It also means you can really point the wrist in the direction you want the ball ti finish.
With this spring like feeling it is still important to keep the shot compact and not over extend so it is too long. You don’t need this so much st all on backhand drives, as the wrist is more fixed and stable in this shot.
Try to focus on adding a small amount of wrist to start with and build it up into your topspins. Another important thing is that the main energy of the shot is still created by the elbow and forearm and the wrist shouldn’t come in too early, it’s best to coil the wrist back like you said and then release it through the ball contact so there isn’t too much movement with it and the shot becomes unstable.
I hope that all makes sense and let us know if you have any more questions on this or need any other advice on it 🙂
