I posted this in the Tiger thread but seemed to get overlooked. A good read for swing junkies.http://www.jssm.org/vol4/n4/18/v4n4-18pdf.pdf
Interesting research article

Interesting Article Thanks
Very, very interesting article. They are testing their model to determine if it can see differences between various handicap golfers before they do some additional work. It is easy to see that the 0 handicap golfer uses, hips and thoraic region more efficiently (and forcefully) than the other players. Also, the 5 handicap player uses more right shoulder and right arm to compensate for a lower amount of work with the hips and thoracic regions (swinger versus hitter perhaps?).
I am not an engineer but interesting results in the table which is easy to understand. Read the table and their conclusions for the summary. Also, low handicap golfer transfers energy more efficiently than the others (as you would expect based on their performance).
The higher handicap golfers use less of everything (generally) and transfers energy via joints far less efficiently (jerky swings versus smooth).
Any other thoughts? This is my very, very quick read (less than 4 minutes while drinking my first coffee).
Mandarin would be great on this.....

Efficiency
This is an interesting article, particularly as it relates to which muscles do the work in the swing and how the work profiles vary by golfer. Unfortunately, the sample size of actual golfers used to test the model is relatively small --- 4. It would be interesting to see more.
Kevin,
The higher handicap golfers (subjects 3 and 4) were actually more efficient. They had the smoother swings . See the text on page 529. The scratch golfer and 5 handicap golfer did more work as they were able to maintain more torque through the swing. The efficiency results are counterintuitive, but perhaps the results would be different if more than 4 subjects were analyzed in this way.

That's right!
"The scratch golfer and 5 handicap golfer generated did more work as they were able to maintain more torque through the swing.", which is called, in TGM's term, "sustain the lag".
