[Simple Tip] Controlling Topspin on Forehand
Hey guys, for those of you who need help on developing topspin and/or controlling it on your forehand, or even backhand, here iss a fairly quick tip I would like to share: http://simplemoderntennis.webs.com/a...in-on-forehand
The time estimate is way too long. ?
That reference says
"How long is the time from buttcap position to the spring forward? At most, half a second."................
Here are some Nadal forehands. We can estimate the time it takes to go from the butt cap position to impact. 240 fps
The best way to do stop action single frame on Vimeo is to press the play pause button as fast as possible.
I count about 11 frames from the time that the butt cap is pointing at the ball until impact.
t = 11 fr /240 fr/sec
t = 0.045 second.
He says < 0.5 second.
I'd say that he is off by a factor of 10X. ?
[1/2 second recorded at 240 fps takes 4 seconds when played back at 30 fps, as in the Nadal video. ]
Thanks for showing me Chas
