Re: Golfing misconception regarding power

hi aft
i think it timing and putting the clubface square on the ball to target. it just doing it thats hard

Re: Golfing misconception regarding power

Hi Bill .
we all should be aware that timing helps to deliver the club head to the ball, but where does power come from.???

Re: Golfing misconception regarding power

lateral slid of the hips, it changes the swing plane and puts the weight onto the forward foot.
whats your take on it aft,
cheers bill

Re: Golfing misconception regarding power

Hi Bill
I think i'll wait to see if we get anymore replies before i give my view because i think my reply will start an interesting debate.

cheers

sounds intresting ????

Re: Golfing misconception regarding power

Hi Atford , I would think the power in any golf shot comes from the whole of the swing up to the point of contact . The turn of the shoulders during the backswing and the movement of the arms during the forward swing. Hope I'm on the right track. It will be interesting to hear your thoughts. Cheers, John B

Re: Golfing misconception regarding power

In my opion , power in the golf swing derives from the energy that is stored in our wrist hinge.
Your wrists are important levers. They set the club at the top and create the clubhead lag on the downswing that results in power.

Examining the delayed release in the golf swing using computer simulation
E. J. Sprigings & S. J. Mackenzie
The objectives of this study were first to examine whether, in theory, a delayed release technique that used resistive wrist torque provided an advantage in clubhead speed; and second, to identify the mechanical sources of power that are responsible for increasing clubhead speed. A 2-D, three-segment model comprising torso, arm, and golfclub was used to model the downward phase of the golf swing. Muscle torque generators, constrained by the activation rates and force–velocity properties of human muscle, were inserted at the proximal end of each segment. Three separate optimized simulation conditions were examined. The first, SIM-1, made no attempt to constrain the natural release of the clubshaft. Optimally activated muscular wrist torque was used to accelerate the clubhead. The second, SIM-2, delayed the release point of the clubshaft by means of a resistive muscular wrist torque. This was followed by active wrist torque to accelerate the clubhead. The third, SIM-3, was similar to SIM-2 except no wrist torque was used to accelerate the clubhead following the release point. The results indicated that there was a small advantage in employing the delayed release technique using resistive wrist torque, but significantly less than had been previously reported by other simulation studies. The use of an active wrist torque following the delayed release was found to be advantageous. The main source of power delivered to the golfclub originated from the passive joint forces created at the wrist joint during the swing. In terms of muscle power contributions to the swing, the torque generator at the shoulder joint produced the highest value (800 W), followed by the wrist torque generator (600 W), followed by the torso torque generator (390 W).

I look foward to hearing you views on this article.

Re: Golfing misconception regarding power

yes sounds good but that set up misses out the most important part the lateral movment of the hips, that both hogan and trevino thought of hips as big moters driving the smaller motors off the shoulders to the smaller moters of the elbows and wrists, its like the machins that they use to test golf clubs and balls but have free wrists as motors to make wrists come in to play unreliably are so had to set up. ag bonner said you use wrists to make club face hit small home runs, meaning he turned the wrists to hit the ball with the club face at impacked.

Re: Golfing misconception regarding power

hi aft
yes very, so many thing add up to making a powerful swing and more important a repeatable one.

Re: Golfing misconception regarding power

Hi All
misconception number 1
The backswing is used to coil up power, ready for the downswing....This notion is as outdated as the earth being flat.

The sole purpose of the backswing is to correctly position the club at the top

Food for thought:- have you ever wondered why 80 % of all golfers across the world have battled with a slice at some point in their golfing life.?

Re: Golfing misconception regarding power

hi aft
i would say the power that is clamed is about right. shoulders move 90% and have a power of = (800w) then the torso that turns 45% and half the turn and half the power = (390w) and the passive wrists with the club force adding to the passive wrist power = (600w). would love to know what the reading would be with no club in the hands, bet the wrist power would be very low.
you made me think again

Here is a link - the stuff at the bottom is the interesting part to this discussion:

Re: Golfing misconception regarding power

I think this agrees with my notion that power comes from the wrists. the forearm and triceps of both arms control the wrist hinge and release.

thanks for the link pal.
