Right Arm Swing and 4 Barrel Swing

[Bigwill]

Pistol - you wrote-: "---but i suspect some amount of active right hand participation don't you wonder why hogan had a tonne of it".

I am amazed that you can infer the presence of active right hand muscle action simply by looking at that photo of Trevor Immelman, and I am equally amazed that you can conclude that Hogan had a tonne of active right hand action in his swing - simply by observing a swing video of his swing.

In terms of what represents active right hand action in Hogan's swing, you now seem to be referring to an active right wrist ulnar deviation uncocking action. Even if I were to accept your argument that active right forearm muscle were involved in Hogan's swing, the muscles that produce that particular right wrist 'karate-chop' action must be the forearm muscles that ulnarly deviate the wrist.

Here is a photo showing the forearm muscles that produce ulnar deviation of the wrist.



The muscles colored in yellow represent the two forearm muscles that produce ulnar deviation of the wrist (1 = extensor carpi ulnaris; 2 = flexor carpi ulnaris). In terms of the volume of forearm muscle bulk, they represent only a small fraction of total forearm muscle bulk. I, therefore, cannot imagine how they can contribute much to swing power through the impact zone - even if they are actively contracting to their maximum degree.

Whatever Hogan meant by "three right hands", I would be amazed to learn that he was referring to 3 x the forearm muscle power contributed by those two forearm muscles.

Jeff,

Since the right wrist is hyperextended in the backswing, why wouldn't the muscles involved in the downswing be the flexors?

Also, you stated earlier that the ulnar deviation is passive. Would that not negate the use of the muscles that do this (ul. dev.), or are you describing active/passive from the standpoint of intent, rather than an actual physical standpoint?
