Forearm after pronation
Hi, I began to notice after some slow mo videos that I've seen. After the player hits the shuttle, the forearm continues to turn. While when I hit, I pronate, hit the birdie squarely and just do a follow through. Is there a difference in the two?
Continuing to turn the racquet makes me feel like it will be harder to hit the birdie squarely.

I'm not following you, exactly. Please clarify. Who are "the players"? Professionals?
Please use the same language describing both examples except where there is change.

Are you referring to follow through?
07-03-2007, 07:41 PM #4
Oh sure. Here is an example http://www.youtube.com/watch?v=sfs16Jde3MU around 40-50 seconds. The man hits it and I can see that he continues to rotate his forearm.
And when I follow through, it means after I hit, and my arms would start going to the bottom left. Does that make sense?
Sorry this is what I mean Dink.
You Swing, Pronate, and hit the birdie squarely. This is where the difference starts. The person on the video continues to turn his forearm. Where I just follow through to the bottom left. Or just left.

I see a couple of reverse slice to induce drop shots.

The overhead swing in ~40-50 seconds is what i'm talking about Pete

I understand what hes saying. Its difference of follow through. The Professionals follow through with their arm still pronating while kaze just follows through with his arm.

The follow through can be different for a full smash, a half/wrist smash, a regular slice and reverse slice.
Half/wrist smashes can be performed with a tap action without proper follow through as seen in Niels Kristian Kaldau's instructional video.
Regular slice does not involve much pronation in the follow through (or, for that matter, before the contact either). In the slow motion video, there is some pronation, I think, because it is a fast drop.
During the follow through of a reverse slice, the arm does not press downwards as much as it does during a square-on smash. So, the arm ends up pronated slightly higher than it does for a square-on smash.
See them frame by frame
Zhang Yawen's smash
Chen Yu's (regular) slice
Lin Dan's reverse slice
These three strokes are discussed in this thread posts 48 - 84.

OK, I believe I understand. You are talking about two different shots.
In the video, Lin Dan is hitting a reverse drop. You are talking about/doing a straight clear or smash.
Lin Dan continues to rotate because that is what is required to spin the shuttle down and well as accelerate it over the net.
With a straight clear or smash, there is no need to rotate the shuttle as it will slow the shuttle down.
If you are going to reduce the travel of the shuttle, you need to spin it, hence the rotation by Lin Dan. If you are going for maximize power or distance, you need to hit the shuttle as squarely as possible with maximum force; your follow through will/should take your rotation to the left of your body.

I know exactly what you are talking about. The simple answer is yes.
I'd assumed that when I smahed my arm protanted , but did so coming across my body - the end up near my left side (say the left hip), but after wathing one of my macthes on tape, I was suprised to find out that 90% of the time my arms continued straight down, ( my right side - I'm rigth handed) even on my big smashes.

Thanks Dink. So I see that some people like vining wolf, goes straight down after the hit. I did read somewhere if you lower your shoulder too much it would decrease power. What do you guys do?
07-04-2007, 12:09 PM #15
Depends on what you mean by lower. There is a certain amount of shoulder rotation, but with any proper hit ( unless a side arm drive) the shoulder would ( or should) remain up.
If you look at a lot of the pro photos wehn they smashing you'll see that thier follow through is down rather than across.
