Does the Follow-Through Direct the Ball?
of Joe
In “Cup of Joe,” we want to evaluate accepted methods of how tennis should be played and coached in the context of the modern game. Some readers may conclude that many of the accepted ways of thinking are now obsolete; other readers may feel their importance is reinforced. Either way, we want to hear from you—about this current topic and on other topics you’d like us to address. Email me at joe@oncourtoffcourt.com and we will try to publish your comments in future columns.

remember those first tennis lessons when I was 6 years old like it was yesterday. As fate would have it, much of the instruction is what I am writing about in these columns. One of the lessons drummed into my elementary-school head was to finish my forehand follow-through in the direction I wanted to hit the ball. I guess it was supposed to work like a steering wheel that would magically direct the path of each forehand hit. Of course, the balls were tossed very slowly, but for a while my coach had me convinced. It was only as I advanced through the junior ranks and started spraying down-the-line passing shot attempts wide that I started questioning that tactic. After all, I was aiming down the line and finishing with my racquet pointing exactly where I wanted the ball to go. But against harder hit incoming balls, the magic steering wheel stopped working so well. If you want to know what controls ball direction, read on.
Q: So, is it true? Can the follow-through direct the ball? A: First let’s back up and identify the parts of the swing and what each accomplishes. The 34

three parts are backswing, contact and followthrough. The backswing is before contact and is the part of the swing that creates power by allowing swing speed to build. The backswing is also where the shape of the swing that leads up to contact is created, and therefore helps determine the degree and type of spin and trajectory. The contact is the briefest event, usually only 2 to 3 milliseconds, and the racquet angle and path during this event wholly determines direction. What happens during contact also largely determines spin and arc. The follow-through is the part of the swing after the ball leaves the strings.
Q: If that’s true, then what is the purpose of the follow-through anyway? . A: The primary purpose is actually to avoid
injury. Think about it. If you have a 50 mph swing and stop short at contact, the tension required to make this abrupt stop could cause physical harm. It would be like a car stopped short by hitting a brick wall. Normally, when a person hits the brakes on a car, the momentum of the vehicle causes the car to continue some distance before coming to a complete
