Kinetic link

[Mike O]

No....

COAM only applies to systems that are subject to a "CENTRAL" force. A central force is one which is directed through the axis of rotation. In the youtube Jeff attached, the spinning device is compressed and stretched by force with is acting THROUGH the axis of rotation. That is a central force.

Its would be impossible to argue that the forces generated by a golfer's muscles during the golf swing gestalt act in a direction which is through the "instantanous" center or axis of rotation. Therefore usage of the term COAM when discussing golf is wrong. COAM does not apply to the golfswing contrary to what some authors and their experts would have us believe.

no_mind

Let me make sure I understand you - you're saying that any distribution of mass away from the center in a golf swing - no matter how much even theoretically- has no effect on the rotational speed of that movement.

Better yet- let's use a non-golf example and you can explain what you mean: If you are pushing someone on a merry go round- are saying that it wouldn't matter how close there were to the center- it would take the same amount of force to move them the same RPM's? That wouldn't be the case- so maybe in that example you would still consider the force - "instantanous center of axis of rotation".

Or let's use an ice skater- the ice skater uses muscles to extend the arms out - and there is a slowing of the rotational speed. So it's not that muscles are involved that ceases COAM.

Help me see your point.

Jeff,
are you for real , you are quoting brian kings words on the kinetic link , not what zenolink describe the kinetic link as, are you serious who are you trying to kid.
This Brian descriptions not the researchers and founders of zenolink.
You pick a quote off someone's web page trying to sell lessons thats not research surfs up good to see your surfing at your age, on your net surfing sorry.

You quote the same graphs on every website all over the world.
The link on comparisions is off tpi's websites of coarse it will be one sided they are trying to sell k-vests .
What research is this who can you provide this as evidence or research, this is pulling peoples opinions off the net , not actual research.

The final graph you present did you see the golf swing , do you ever bother to think this person could have also had an over the top swing as well.

Did you ever to bother to think the graphs T.P.I present are swinging over the top, does greg rose even know what over the top swing is ?
he is a chiropractor.

the last graph you present is ball velocity not on the biomechanics of the swing they are measuring ball velocity, once again did you see these people swings were they also over the top swings.

There is a difference between net surfing and research Jeff, how about doing real research before you start presenting to the world who is right and wrong in biomechanics.

I can't laughing stop this is a joke what are you trying to prove.
Is T.P.I paying you?
