So a ground up sequence is important and early work is important but only as much as someone physically can perform.

Because you do not want the body to override lining up the club for impact.

Brilliant!

Thanks for sharing Mike. Very interesting stuff and helps to look at it again, after viewing similar graphs at the Summit.

In the total power chart it looks like the 13 handicap and 18 handicap have strange blips. I would guess they are lurches and the like to try and create more power that backfire but was wondering your take on it.

Also the kinematic graph is of an ideal sequence, do you have a sequence from one of the higher handicappers to compare it to?

Again thanks for the sharing, looking forward to the published work!!

(hurry and try to get it out before the spring, I'll be too busy to read it! )

Steve,

There are some blips in the graph for those golfers. You can see some power drops for a brief moment. Their ability to do work at an ever increasing rate was obviously compromised in those moments of time.

The kinematic sequence graph clearly shows the order of 'peaking' of the different segments. If you look at the graph you will see the peaks in the order of Pelvis... Trunk.... Arms .... Club. Take note the peak of the trunk and the arms are almost identical as a function of time. The trunk peaks slightly earlier but I don't think the golfer would be able to tell the difference. Most 'tuggers' don't peak the arms early enough.

Hope that helps

Mike,

I think this could be a topic for a "for sale video"

Mike,

Could very well be. It boils down to the golfer over emphasizing the linear acceleration of the coupling point of the club. If the focus of the 'tugger' shifts to torquing they will eliminate any and all tug. Probably sounds confusing but thats about the only way for me to describe it at the moment
