Not Accelerating Through the Ball

[saevel25]

Mark Crossfield at the Ping facility. An interesting note is the Ping guy basically showing that the hands are slower at impact then they are by your right foot in the downswing (FO view). 

Just to show you the idea that you need to accelerate through impact is not true.

Note to the guy in the chair, lag happens in the swing when things go well ;)

Correct me if I'm wrong, but I believe the "guy in the chair" is the guy who works in that room and gave us the tour of that room in September.  Also, amusing that they were using the same examples (Angel Cabrera) that they gave us.

In fact, here is a picture @Club Rat took. That's him!

Thought I had uploaded this one, also.

It's probably is. Still, I would probably say that other things cause casting the club and lag happens because of keys 1-3 then trying to focus on it. ;)

Of course the hands slow down. That's how the club catches up and passes the hands.  The feeling of keeping the hands going quickly, though, often helps people.

Interesting observation. Were they measuring change in hand velocity in across all dimensions (along the arc of the hand path) or only along the x-axis (linear velocity)?

I ask because the lead arm at least is or is near to being torqued upward by the lead shoulder. The force of torso rotation is starting to turn the hand path upwards. Also when the hands were at the trail thigh the hands were going with gravity along the arc while just before / through / around impact they are starting to fight gravity going up along the arc. I think some hand deceleration around impact would be expected for these reasons.

They're measuring hand speed along the hand path arc. It tends to reach peak speed around the trail thigh.

But the slowing of the golfer's hands is a dynamic effect. In this part of the downswing the golf club has its greatest negative angular acceleration. The rotation of the club  in the plane of the swing produces a force by the club on the golfers' hands that slows the hands even when the golfer is trying to move them with ever-increasing speed. - T.
