Nadal string tension ?

Question

I think Nadal uses a tension of around 53lb. How is it possible for him to hit the ball as hard as he does and keep the ball in , is it all due to the topspin ??

I string my racket at 62lb, have a similar rackets to Nadals and hit with quite a bit of topspin.. I tired my strings at 58lb and the power difference for me was too much!!

Answer 1

It's the spin, angle, and placement his balls always look like they're going long, and they just drop.  He's a lefty, and lefty's tend play with more spin.

Answer 2

Its not the topsin its the angle at which he hits it!

Answer 3

Nadal puts much topsin in forehand shots and sometimes in backhand shots. I guess he has more control over the ball and puts a lot more topsin in them.
