A throwing form that allows you to throw effectively is something that you can work on. In this post we look at one aspect of effective form— torso torque. The expression refers to the way a shooter twists his torso while throwing. (See Byron Putman: Pétanque: The Greatest Game You Never Heard Of (pp. 82-85)— highly recommended.)
When you watch world-class shooters you will often see this…
- Before the player starts his backswing, he is basically standing upright, with shoulders level and chest facing forward toward the target.
- As the player begin his backswing, he leans forward slightly— this allows for a higher backswing. His throwing shoulder drops a little and moves backward, causing his torso to twist backward slightly. At the same time, his non-throwing arm starts to move backward so that at the height of the backswing both arms are raised behind his back, balancing each other.
- The player begins his throw. During the throw, his throwing shoulder dips slightly, so that during the throw it moves forward gracefully in a shallow U-shaped dip. At the same time, his torso starts to untwist, so that at the end of the follow-through his throwing shoulder is in front of his body. At this point his posture is “open”— an observer standing to his non-throwing side can see the front of his chest, as in this photo of Marco Foyot. (For more pictures, see How to throw a boule.)
Here is a sequence of clips from the Youtube video of Ledantec shooting during the final of the Masters de Petanque 2004.
Here is the whole sequence as a slideshow.
Almost all of the great shooters (to a greater or lesser degree) demonstrate this ideal form of torso torque. And you will see it (again, to a greater or lesser degree) in pointers as well as in shooters.
Why do players move this way when they throw? Byron Putman calls it “torso torque” because he thinks it is a way for a player to use torso rotation to add power to his throw. Personally, I find that the motion of my body is more natural, and my accuracy is greater, when I twist my torso and bring my throwing arm forward while throwing. I suspect that shoulder anatomy is coming into play here, but I don’t know enough anatomy to be able to say exactly what is happening.
