Greetings. I am a graduate engineer who has been trying to play golf since 1995, although I recently started back after a 10 year layoff. I am interested in swing theory in order to become a better golfer and because of my background. My highest measured clubhead speed was 128 mph at 33 years old and 5'7 155 lbs. I am now 55 years old and have back problems but can manage 110-115 with the driver. I hope to have my h.c. to the single digits by the end of this year.
My understanding of the golf swing is not necessarily difficult but is based on standards physics and simple knowledge of "mechanics of materials" and biology. The most efficient golf swings use various muscles in the body to create energy to use immediately or to store temporarily in elastic tissues which are then transferred and released eventually at the point of impact. There are various mechanical interactions the most important being between the arms and hands to efficiently transfer the energy created by the body to the club shaft.
I have been interested in swing theory since I started playing golf. I have come to the conclusion that there may not be any pro level teachers that understand the golf swing from a physics standpoint. This does not mean they are not effective teachers, only that they don't understand the physics of the golf swing.
I look forward to discussing swing theories with others on this forum as well as sharing my knowledge as well.

Greetings chipa and look forward to your posts regarding your theories concerning the golf swing.
To be honest I think its impossible to really understand exactly what's happening in the golf swing without detailed measurements of the 'force /torque' vectors being applied at the handle (with a very high sampling rate) plus electromyography monitoring on all the muscles being used. But even the latter may not be enough because 'Electromyography' cannot measure an isometric muscle contraction.
All we have at the moment are qualitative theories that might closely match some of the research articles we've seen (ie. Koike, Choi) and the inverse dynamics which unfortunately decomposes/simplifies the complex kinetics into linear forces and couples (about the COM).
Even Koike and Choi are using 'inverse dynamics' to provide theorised 'moment of couples' in each hand.
