libro,
Nothing new but there are as many golf swings as there are golfers and what ever gets the job done gets the job done. That being said one can still ask the question what would be kind of an optimum way of going about the torques in down swing. Should one use a steady effort from the shoulders, or perhaps start very slowly and be more explosive closer to impact. Or why not, really try to bend the shaft from the very start but let go and free wheel through impact. Idem for the wrist torque. Should one simply strive for a negative retaining torque throughout the whole down swing. Or at some point in the down swing reverse the wrist torque and apply a vigorous positive wrist torque closer to impact.

Brian,I know how you feel, Mandrin.
Sometimes, the interest just isn't there.
When I sang, the more people that were in the bar, and the more people paying attention to me, the better I sang.
So, here is my shot at Jon (libro's) question.
From the top you use PULLING FORCE, from the ground up as you move toward the ground somewhat.
As the shaft gets to VERTICAL for the last time pre-impact, you start adding PUSHING FORCE with the right arm and the wrists and hands.
As you come "out of the ground" and pull away from the ball somewhat, you use this opposing force to stop as many components as you can, as fast as you can, as near to impact as you can.
How did I do?
Jon,
, but why??, Why does his trail hand come off more than other players in the through swing? Is he more efficent, or is he maximizing efficiency for him..if not, how do we know?? Whew.. Difficult subject indeed....Thanks for your hard work Mandrin. I look forward to asking more questions and making my little coconut work harder in the future.
.Jon,
Intuitively I feel that more detailed measurements of golf swings will not straight forwardly lead to clarity. Perhaps even more confusion before the dust settles. For instance, Dr. Nesbit claims to measure acceleration of the hands of pros during impact but Dr. Grober's measurements don't agree, actually measuring deceleration.
There are kind of two approaches. Simplification to the bare essentials and analyzing the swing with simple double or triple pendulum mathematical models or an approach such as by Dr. Nesbit, making extensive measurements and applying inverse dynamics using sophisticated models.
I have to dig into this to quantify it, which takes time, but I do believe that an efficient swing really consists of two consecutive parts, a active phase (yang) followed by a more passive phase (yin). Efficient implying that for a given amount of work expended by the golfer he gets the maximum possible amount of kinetic energy into the clubhead. However this does not necessarily imply that an efficient swing produces maximum possible clubhead speed for a particular golfer.
vjsinger,Truly an exciting and interesting subject. Here is what I know..Using a "feel" of pushing with the trail arm when the shaft is at last vertical in the through swing AND "feeling" a stop at collision has helped my game over the last couple of weeks more than any other feel/swing thought that I use. This for me, makes me extremely happy. I do have questions....about swings and efficiency though. I wonder if Vijay Singh feels the same things as vjsinger... I already know who is more efficient
