Please explain
Take a look at this link.

What is going on in the graft on the down swing is the lower body can only go as far as the internal rotation of the left hip allows. This is why you see the hips slow down just before impact. In the graft it shows the lower body slow down as it reaches the limit of the flexibility of the left hip internal rotator. This will then slow down the shoulders, arms and hands. To prevent the hips from stopping before the finish the right foot pivots up on to the big toe and the hips, shoulders, arms and hands coast to the finish. This down swing action does not add club head speed or snap the kinetic chain as they want us to believe.

Mike Austin’s power secret was that he applied thrust and torque to the handle snapping the club head maximizing club head speed on the down swing. Here is how he did it. At the start of the down swing his left arm which is connected to the upper body which is connected to the lower body provided an opposing force to the thrust and torque of the right hand and arm. This opposing force activates muscles in the body to try to prevent the thrust and torque from moving down for a fraction of a second.

Then the opposing force is overpowered and the thrust and torque release, snapping the club head with maximum acceleration through impact. If is a very powerful move and is not detected with this analysis program. Until the thrust and torque values on the down swing are tested with proper equipment it is impossible to understand what is really going on. With this analysis program they would think it is due to a snapping effect of the slowdown of the hips, shoulders, arms and hands. This is not what is happening.

With Mike Austin’s swing pattern applying thrust and torque to the handle on the down swing the graft measurements of speed in this link would look similar for the lower body, upper body and arms but the club head speed will be off the chart with maximum club head speed from the thrust and torque applied to the handle. The club head speed gains can be as much as 15 mph when using this action. How do you explain for the added club head speed with this system? You can’t. This chart at best is just showing the speed or mph of the hips, shoulders, arms, hands and club head on the back swing and down swing through impact and to the finish. It is not showing how this added club head speed is obtained.

I am now working with a program that shows the thrust and torque values applied to the handle during the down swing including the percent of club head speed gains with this action. I am testing a swinging pattern without the thrust and torque applied to the handle during the down swing. A hitting pattern with thrust only applied to the handle during the down swing and a swinging and hitting pattern with thrust and torque applied to the handle during the down swing.

The results so far show there are little differences in just swinging or hitting. When both thrust and torque are applied to a swinging or hitting pattern I am seeing gains of 5-15 mph depending on the level of the golfer. I also tested a long drive golfer and he increased his club head speed 15 mph with the thrust and torque added to the down swing. He was at 135 mph before and 150 mph after. He might make it to the finals this time with that club head speed.

The point to all this madness is it is an easy way to increase club head speed for the weekend golf without increasing down swing pivot speed. More club head speed with accuracy. The snap the kinetic chain folks want you to increase the down swing pivot speed and put the brakes on just before impact. Now that is ridicules and does not add club head speed.
