Bigwill - I can understand the idea of an "intent" to release the right wrist bend without actually releasing it. However, I think that the right wrist is actually released during the release of power accumulator #3, but that it is not released due to a right wrist palmar flexion action, but rather due to a right wrist ulnar-deviation action.
Here is a photo of Trevor Immleman during the followthrough phase of the swing.
One gains the "impression" that right hand is rolling under, and I think that it's merely due to fact that the right wrist passively deviates ulnarly during the final stage of the club's release action.
Jeff.
I think we may be looking at the same picture from different points of view.
I agree that it is released post impact. I don't get the impression of the right wrist rolling under, though. I do see that is flattened, even slightly flexed, in addition to being in a position of ulnar deviation.
Is it possible that the ulnar deviation is simply an effect, rather than a cause (club pulling the right wrist into ul. dev.)? I would think that with the momentum of the club moving at decent speed, it would be pretty difficult to prevent ul. dev. of the right wrist post impact.
You write-: "Is it possible that the ulnar deviation is simply an effect, rather than a cause (club pulling the right wrist into ul. dev.)? I would think that with the momentum of the club moving at decent speed, it would be pretty difficult to prevent ul. dev. of the right wrist post impact."
That's how I think of the situation. I think of the right wrist's ulnar deviation action as being passive (reactive to other forces) rather than being active (due to active muscle contractile forces within the right upper limb).
