Roddick 150 mph Serve Analysis

 

Andy Roddick has the most efficient serve on tour because of his Range, Sequence, Separation, and Hip Speed. Tomas Berdych, who towers over Roddick at 6'5", does not serve as fast because of the restricted Range in his arm and hips. Our slow-motion and frame-by-frame measurements identify the critical elements in Roddick's serve, and also show where other players fall short. We also show how many degrees of flexibility you need for an efficient, powerful, and effortless serve, and a simple test for hip strength ( http://www.swing-speed.com ).
