Shoulder Rotation

April 29, 2014

Shoulder Rotation

One of the most common problems with beginners is they don't rotate their shoulders on the forehand. Several players have this problem in beginning/intermediate class I teach on Monday nights. Even when they learn to rotate the shoulders when hitting forehand to forehand or in multiball they tend to fall back on arm only (i.e. no shoulder rotation) when doing footwork.

The solution I've found is to emphasize the rod-through-the-head coaching technique. When you hit or loop a forehand, imagine a vertical rod going through the top of your head, and rotate around the rod. In reality, the head normally moves a little forward doing the stroke from the back-to-front leg weight transfer, but often very little is needed since most of power comes from torque, as the body rotates in a circle. So for beginners especially it's important for them to focus on this idea of rotating their shoulders around this rod through their head. This gives them the right feel of the shot, and something to focus on to fix the shoulder rotation problem - and when they do footwork drills, it tends to stick with them and they continue to rotate the shoulders properly.

If you watch most world-class players, you'll find that much of the secret to their ability to produce great power and recover almost instantly for the next shot is this idea of rotating in a circle, so they end up balanced and ready for the next shot. The head does move forward or sideways some (and often up), and does so even more when rushed after stepping around the backhand corner to play forehand, but in general most of the movement is circular, creating torque while staying balanced. (Two keys to balance: keep weight between your feet, and use your non-playing arm as a counter-balance to your playing arm.)

Here's Men's Single's World Champion Zhang Jike playing a chopper. Note the circular rotation? His primary head movement is up as he lifts the heavy backspin. Here's Zhang Jike looping in multiball, against both backspin and topspin. (In the latter you'll note that the more rushed he is when moving to the backhand the more his head moves forward or sideways.) Here's Ma Long (world #2, former #1) demonstrating (and explaining in Chinese) his forehand (and then backhand) drives. Here's Timo Boll (former world #1) demonstrating his forehand loop. Here's a lesson on forehand counter-hitting by ttEdge. Even when smashing a lob most of the motion is circular - here's a demo on smashing lobs by PingSkills. (The link should take you to 1:47, where they demo the shot.)

Knee Update

After hobbling about on Friday after hurting my knee on Thursday night while demonstrating forehand looping for a class, it got better over the weekend. So I probably only wrenched it. I can still feel a slight strain there, and will go easy for a time, but it's mostly okay.

History of U.S. Table Tennis at Amazon

Tim Boggan's History of U.S. Table Tennis (now 14 volumes, from the sport's beginning in this country to 1986) are now on sale at Amazon. You can order direct from Tim Boggan (and he'll sign them) or from Amazon. (See links below each volume.) How can any serious player not buy these books??? (Disclaimer: I did the page layouts and much of the photo work for all but volume 1.)

World Championships

I was debating whether to do Worlds coverage here in my blog, but they are already doing an excellent job elsewhere, so I'll just link to the following two places, where you'll find results, articles, and lots of video. (I'll probably run this segment daily throughout the Worlds.)

Shot of the Day from the Worlds

Here's the video (36 sec, including slow motion replay), where Xu Xin (#1 in the world) pulls off this around-the-net counterloop against Tsuboi Gustavo of Brazil (world #69). (In my initial posting, I inadvertently said Gustavo pulled off the shot. Special thanks to Douglas Harley who caught this. Hey, they're both lefties!!!)

Here's a preview (2:35) of Brian Pace's new video.

Here's the video (7:26) from PingSkills.

Reverse Pendulum Serve

Here's a nice video (1:12) that demonstrates the serve, using slow motion and a colored ball so you can see the spin.

Don't you love Xu Xin's shirt?

Ping-Pong the Animation

Here's the video (3:55) of this anime cartoon. It's in Chinese, with English subtitles.

Jan-Ove Waldner in TV

Here's a video (3 min) from five years ago where Waldner beats a TV host with various implements as a racket before finally losing with a banana! I believe it's in Swedish, but you can follow what's going on.
