I've finally analyzed the mechanics of Gasquet/Wawrinka/Almagro backhand

This had been puzzling me for ages because Gasquet's and Almagro's backhands look really similar to me, yet the ball really fizzes off of Almagro's racket with pace, and it loops up high with Gasquet (though it's not a soft shot, it kicks up like a mule).

Well, I was watching frame by frame youtube footage and found that before contact when the racket is dropped lowest, Gasquet has the head of his racket significantly lower than butt-cap, causing torque in the forearm/wrist. As the stroke progresses, the torque releases and the racket head snaps upwards to the same level as the butt cap (and beyond that, later) to contact the ball at the same time as the arm itself is moving upwards to contact, so you have these two actions both brushing the ball upwards for extreme topspin on the backhand.

By contrast, when the racket is dropped lowest for Almagro, the racket head is more or less perpendicular with the butt cap. There is not the same torque on the wrist/forearm, and their isn't the same degree of upwards snap of the racket head. So even though Almagro finishes very high over his head, he has driven through the ball more than brushed it upwards because there wasn't the extreme racket head drop of Gasquet's backhand prior to contact.

Wawrinka has more racket head drop than Almagro, and less than Gasquet, but he involves his core more than either of those two. This has the effect of flattening his stroke out because it frees his arm to move in a more horizontal manner. If you hit the ball with your chest closed, your arm naturally needs to move upwards because your arm cannot wrap horizontally round your back unless you want to pop your shoulders out (or you're Dimitrov). However, if you are also rotating your core into the shot as Wawrinka does, then you can finish your swing relatively low as your rotating core allows your shoulder room to swing across your body whereas your scapula would block that movement if your core didn't move and stayed in a closed position. I've noticed that Wawrinka finishes his stroke relatively low for a one-hander, and I'm sure this is why.

So, ranking the topspin of all three of these guys, Gasquet is on top, then Almagro and Wawrinka are roughly tied. Almagro finishes his swing higher, but does not initially drop his racket head as low as Wawrinka. Wawrinka finishes his swing lower, but initially drops his racket head lower than Almagro, so these two cancel each other out and I'd say they hit roughly similar topspin. Probably Wawrinka hits a little more.

Mechanically, Gasquet and Almagro are pretty similar, it is just the difference in racket head drop that makes Gasquet's swing more 'circular' and spinny, and Almagro's more 'direct' and flat. Wawrinka backhand is a completely different style with the increased core rotation being a pretty fundamental difference.

Your feedback (do you agree with the analysis?) and input is appreciated guys
 
Wouldn't using the core for the backhand be better than just the arm only. So wouldn't it be best to hit like Wawrinka?

BTW: I was wondering about same thing about various players BHs. If you could add Henin and Haas to your list that would be great.

I'm trying to figure out who's got the best bio-mechanically sound backhand to copy!

To copy? Any one player with a traditional one hander (Haas' technique is especially easy to copy IMO). Wawrinka's core motion makes his one hander quite hard to copy so that it can be used consistently during match play as the timing is very challenging.
 
Gasquet and almagro have more extreme backhand grips - alamagro does use less wrist for spin as he cocks his wrist straight back on the backhand whereas Gasquet cocks his wrist upwards more (similar to haas although haas has very conventional bh grip). The upwardly cocked wrist allows gasquet to drop the racket head quickly/violently and thus get under the ball for more spin. He can flatten the hell out of it though too. Take a look at Gaswuet and Haas bh slow mo - hard to tell whether they are about to slice or hit topspin when they start their take back due to the way they **** the wrist.
And i would have to say Wawrinka is probably just as heavy as Gasquet. He hits it with the shoulder turn of a two-hander, and has a conventional backhand grip, which allows him to get tremendous racket tip through the ball (something two handers get easily) thus helping to impart more of that controllable spin.
 
The advantage of watching Wawrinka play is his big motion clearly shows the swing path. All of his strokes show basic swing path very well.

There is not much secret in 1HBH. Know the swing path well. Your body will take care of the motion naturally.

I don't know how many times I'm going to repost this breakdown, but the key is in the hips. It's really simple physics. I remember Gils Reyes in an interview (couldn't find it) talking about a hip strengthening machine he developed for Agassi that he was fairly secretive about and wouldn't show cameras. A lot of players don't focus on hip strength nearly as much as they could.

The reason why power is derived from your hip, is any rotational acceleration that occurs at the hip is multiplied by the lever of your arm. Same as one of those little children's propellers. The amount of multiplication is the ratio between the distance of the racquet tip and the center of rotation (the middle of your body), and the distance between your swinging hip and that same axis. Divide the racquet tip distance by your hip distance and you have your multiplier. This is the key to the SSC forehand and getting that huge whip, even with a high swing weight... I won't even start about the differences in power between a 350sw and a 320, because it's night and day lol. I think there's some hip training company that has a video about all of this. Can't remember the company, but they pretty much explain and demonstrate it all, with their rather over-priced piece of equipment. Anyway Stan's backhand has by far the most hip movement. The guy in this video breaks it down very well.

You're so right in the sense that people don't focus on hip strength enough, when in fact our hips are the basis for a lot of athletic, explosive movements. Hip flexibility definitely plays a part too, as all the sitting people do really stiffens and weakens the hips.

I think the difference between the racket drop, swing path and amount of topspin can be explained by how extreme their grips are. Gasquet uses the Extreme Eastern grip. It naturally leads to a very closed stance, pronounced racket drop, and vertical swingpath with a high finish. Almagro and Wawrinka use more conservative grips and hit flatter.

Yes, Wawrinka rotates into the shot (2HBH-like) - perhaps he is the only top player with the "modern" 1HBH.

And yes, Dimitrov benefits from his unhuman shoulder and back flexibility (http://youtu.be/z66yOJSpsKU) that delays racket deceleration long past the point of contact.

Not only that, but weakened hips increase quad dominance, promoting failure/damage to the knees. Often resulting in ACL tears etc.

I'm a big pusher of hip strengthening for all athletes.

Stop giving away tennis secrets for free, man :evil: :)
Anyways nice, vid and I agree 100%
