This has been one of the most important videos in my way to understanding the technique of the forehand loop. We have mentioned it here several times in the last years and I could not find it today but with a bit of sleuthing I could find Wei Wang's channel. A long time ago the video was hosted on alphatabletennis.com and from there with wayback.com I pulled threads, it was fun and the reward came.

We also used the video to discuss why Maze broke his lower back/sacrum and later on, when Zhang Jike started the cortisone shots and eventually gave up competition, the discussion took another boost.

That video shows how hard Maze is on himself and at the same time how smooth the kinetic chain is when we Ma Long loops in the background. There lies the incredible value of the video, smooth v. hard. Long career v. shot in flight.

Zeio has great posts about it that I can't find. Also blahness in that defining http://mytabletennis.net/forum/dangers-of-waist-rotation_topic85492_page1.html" rel="nofollow - waist rotation thread .

You can minimize your chances by following certain techniques, but there comes a point where your body can either handle the training load or it can't. Same goes for ANY sport! You must adjust for your own strengths and stop doing things that cause damage. 

Maze appears to use a lot more elbow/arm to generate power, which you'd think would lessen the strain for some other areas. 

Timo is 40+, uses similar technique to Maze and still competes. 

From when MAZE was still pro (not retired) I remember translating a euro forum stating that his training ethics isn’t comparable to TIMOs

Mamba mentality 

I should have let the question in suspense only to talk about the value of the video that's real.

I find interesting that you say technique was induced by bodily limitations, that's new to me, I totally get it but I had never thought about it that way. Thanks for sharing the info about what limited MM's career.

stiltt, no reason to apologize (I didn't there was anything about your hypothesis or train of thought that was arrogant). We are just exchanging thoughts. None us are pros :) 

There are 2 Danish people people where I work and they both know MM by name and one knows where he lives. What a star, he brought the fighting spirit of table tennis to the level of MMA and at the same time he had so much touch and finesse (not saying mma technique can't be subtle, I am sure anything at the top level is subtle but I never went there), he was the quintessential semi-god sports can produce.

Tennis Elbow - tensing your arm and elbow too much even when doing backswings and not during at the time of ball contact. Also, again due in part of not snapping or flexing your elbows properly upon contacting the ball when doing forehand drives or loops.

Lumbar back pain - several factors like bending over of body but knees are not that bent, non-coordination of body parts when doing backswings until follow through (the shoulders example have already finished rotating while the waist still not has not rotated), having a straight back instead of the body leaning forward which results to a tighter back.

I usually teach this especially to beginners and older players. It supports my enforcing of proper strokes, footwork and technique to help avoid injury.
