I also cannot understand an automatic causal connection between a right arm throw and lower body activity.

Peter Croker also proposes such a causal connection in his hand swing theory - see http://www.petercroker.com/englisch/...olferapril.htm

However, both Peter Croker and Tom Tomasello are both presuming that the lower body will respond appropriately. However, "appropriate" with respect to the downswing pivot action could be considered to be a learned behaviour and not necessarily an automatic action.

Jeff.

Good point about learnt or automatic...they might be the same if automatic assumes the player understands some key constraints. (in reality no human can assume this from a naive condition...so most of us have to learn and train pivots).

Now you can learn the pivot motion which will enable the right forearm to do its job ...or you can learn the right forearm motion and secondarily discover what your pivot then needs to do to accomodate this motion. Either way there is a degree of learning/training.

I think that the right forearm motion described by DG, TT and EE can become the centre of focus for a player if their right forearm has learnt to move within a "machine" which has certain constraints (constraints on movement)...or "essentials"...or "imperatives" which must always be in place for the right forearm to dictate to the pivot...

The right forearm does not dictate or directly force pivot to respond in a sequential manner...the pivot makes preparatory moves to allow the right forearm to move in its desired manner , beyond impact to both arms straight. It does this unconsciously to allow the constraints on machine to be maintained....


Those constraints are that lag pressure is maintained, straight plane line, steady head, balance etc...you have seen most of these somewhere before

SO... you need 3 essentals, 3 imperatives and straight plane line (most notably through impact)....if your pivot has been programmed to achieve these...then and only then will the right forearm...or hand for that matter...appear to cause movement of the pivot.

PLEASE NOTE...that appearance of right forearm causing pivot movement occurs to the player him/herself alone!!!....why to them alone because that is where their conscious brain is focussed. To the video camera it will still appear that the hips are moving first...and they are.... but they have learnt that they have to do that if the right forearm is going to take its intended path beyond impact and all other contraints are in place and maintained.

If you had an automaton which could automatically maintain balance and steady head etc....then all you would have to do is program in the right forearm flight plan and the automaton wold make sure everything else moved in an appropriate way.... but the human needs some learning...and you can train from the outside - in (move the hands as directed and let the pivot work out what it has to do) or learn from the inside out ( train that pivot so that , as long as the hands do nothing, the hands end up right)

Most people choose the latter, TT and HK were suggesting the former...although Homer would probably have started with zone 1 (pivot essentially) if it were particularly unruly.

Here endeth the lesson...
