as a topic asked... my friend said most of the trained players, they smash on part A and without trained players smashed on part B... is it true? By the way which part does give a most repulsion?
They don't call it the "sweet spot" for nothing. Hitting it near center gives you the most repulsion.
I think a lot of more trained players will go for part A, simply because you will get more racket head speed there, and so end up with a faster smash, but no doubt that the sweetspot provides the most repulsion.
Watch out though. If you try to aim too much for A, you will end up snapping yrou strings REALLY fast, maybe even on the first hit. I experienced this at least 3 times already, so now I aim for AB, more on the b side though
but how to train to smash on between A and B? I cant catch about the timming, and yet not cauching...
if you've played enough, your muscles will be timed and trained with your eyes to have your arms go through the motions naturally. its just like how some basketball players can do three pointer free throws with their eyes closed. its all practice.
Right on the sweetspot! Love the feedback(fraying) of my 88ti's which illustrates where I keep on hitting
There are different sweetspots: B is sweetspot with most comfort (less shock to hand). A is sweetspot for most power. Differs with positon of your hand. Nice book of howard brody: the physics and technology of tennis.
My coach told us that the hitting spot irregardless whether it is Smash, Drop shot, etc, the hitting spot should be around the line of A & B. And if your string break around there, then you should have been hitting at the right spot.
I thought I'd get the most repulsion from B but A and C definitely gives me the most repulsive feeling of vibration and broken strings with A as well.
Look for wear signs on your strings to find out if you are hitting at the sweet spot. If not, readjust your timing, train and train again, and/or change your racquet.
