How does Roddick serve upto 155 mph?

Question

How is that possible? I can only serve up to70, and that's like 1 out of every 10 serves.

What does it require to serve that fast?

Answer 1

I think he has that ability to serve with the strength coming from both his arms and torso, making it a strong combination for a strong serve.

Answer 2

hey he might have a fast serve but if u can only serve at about 70 but have grat placement, your serve is as good as his.

Answer 3

It has to do with the way he bends his arms. Of course there is the need bend and torse twist which increases the racket speed. All players have that. But Roddick also has this funny crab like hand motion. By bending his elbow the way he does, he gets even more racket speed. But as I can imagine, there will be less control as well. That essentially characterizes Roddick's serve - high speed, less control and accuracy. Also less disguise.

So far I've compared Roddick with other tennis players. But why do skinny people like Roddick serve so much faster than big strong guys like Nadal? Who knows, but it may have something to do with twitch muscles. Twitch muscles are the difference between sprinters and distance runners, and also between fast bowlers and medius pacers (if you're into cricket). It may very well explain hyper fast servers like Roddick.

Answer 4

he gets asked that question a lot, and he can't even explain it.-

but what he does says is that ok servers serve with their arms; good servers serve with their arm and torso; and great servers serve using their legs too.-

i read somewhere that when he was little he couldn't serve fast, so one day ha got pissed and started hitting the ball against a wall in his backjard, and he did it until he could serve like that.-

someone took the time to analize his serve and put it into physic terms, here's the link, it explains the angles and stuff about it.-

good luck!!

Answer 5

roddick can serve that fast because:

he's tall which helps A LOT

he probably has a very strong upper body (shoulders, torso etc etc)

and his knee bend...(the leg drive)
