How to get more Clubhead speed...
Anyone interested in finding more club head speed (which is everyone one would assume) should read the following then follow their work. I'm telling you there is GOLD in the pot at the end of that rainbow.
http://www.asme.org/NewsPublicPolicy...?PrintPage=yes Reducing radius is the key and there are many ways to skin that cat. El Tigre "snaps" his left leg and is so doing move the left shoulder socket up. That's probably not the best way though lest ye too eventually need surgery. Forget about "snapping your kinetic chain" (its bs anyway) learn to control your HAND PATH! |
Whut?
I would like you to clarify hub radius and ways to reduce it.
Thanks, UPP in stunning Ohio |

Hub Radius
It may be a term Nesbit invented I don't know but that doesn't matter.
Think of a wagon wheel. YOu have a rim and you have spokes extending to the hub (which has a certain radius). Now look at figure 2 of : http://www.motionanalysis.com/pdf/2005_nesbit.pdf . Those are diagrams of golfer swings (Think of each club freezeframe as a spoke with the head on the "rim" and the grip end on the "hub". So the Hub is the "path" your hands take from the top down to and beyond the ball. The "instantaneous" radius of that path is what matters. You want it to decrease (This is what prevents casting and maximizes club head speed). If you fit a curve to that hand path of a better golfer it would look like a contracting spiral. http://2.bp.blogspot.com/_3ev96wpPYV...piral_1000.gif |

The end of the Age of DS extensor action?

?
It should be so; as the better swing has a bent right arm at impact.

Parametric Acceleration.....
Did you know....
if you tug on the string of a simple pendulum at just the right time you can inject kinetic energy and increase the amplitude of oscillation? http://www.millersville.edu/~physics....the.month/34/ In that experiment the student is using a loudspeaker which tugs up and down on the pendulum string at just the right frequency in order to increase the amplitude. Its called parametric acceleration. The same principle can be used to extract energy. When the phasing is such that it extracts energy, its sometimes called: active vibration control or active vibration damping. What's this have to do with golf in general and this thread in particular? Its the same. When the club is releasing it is like a pendulum, the club is swinging about a point at the wrists. While we cannot shorten the length of the club shaft during the swing we can apply more centripetal acceleration than is needed to keep the club rotating. We can tug "UP" at just the right time thereby injecting kinetic energy to the club head. When done in the final stage of the downswing this is effectively the same thing as "reducing the hand path radius". In 2002 a Japanese scientist wrote a paper proving the amazing efficacy of this technique to increase club head speed called: Parametric Acceleration in Golf Swing. http://www3.interscience.wiley.com/j...TRY=1&SRETRY=0 http://sciencelinks.jp/j-east/articl...06A1001780.php All long hitters do it. They may not know they're doing it ... but all long hitters inject that final dose of energy by "pulling up" at the end of the downswing. Some even end up on their toes as a result like Bubba. One interesting bit of data reported by Nesbit is that a wide range of players have almost exactly the same hand speed profile (bottom set of curves on link below notice its not slowing as others suggest either but that's another issue) http://www.jssm.org/vol4/n4/17/F4.htm Their hand velocity profiles are nearly identical yet clearly some swings are much more effective than the others. What's the difference? Its the path their hand follow reducing radius vs. non-reducing (or even increasing) radius... its pulling up at at the last second vs. not pulling up.. Its all in the hands folks... use your body to make your hands go where they've got to go. |
What is the ideal way of pulling up for the tournament player? Moving the left shoulder socket up?
When you pull up do you also need to lower the level of your head or shoulder unit to keep the club head path optimal? Thanks OB |
Hitting 'Up' with Wild Bill
Quote:
Bill felt like he was "hitting up", even when he took a divot. On his long shots, he tried a right hand uppper cut to the chin. In his own words, he tried to "knock myself out". With his big pivot and the principal 'clubhead swinging' feels the thumb and forefinger of both hands (all other fingers much lighter and even letting go), his Golfer's Flail (Sketch 2-K) really worked. :) |

Sadlowski has figured it out about half way through is the slow motion. When you come down that steeply you had better have total control of you hinge motion. |
Quote:
Great swing - great motion! I like the way his left wrist is bent well into the downswing..but the clubface is turned to the plane and the sweetspot appears to be on plane. The left wrist in a swinger is subordinate to the physics of swinging....bent when it needs to be to max out his late wrist uncock and still be on plane... but flat when it must be! Would love to hear what he feels in his PP3 if he were to "tune into" its wavelength!:golf: |

Any advice on how to use this (monitoring clubhead feel) without focusing so much on the head that you risk throwing the head? |
Wild Bill
Lynn,
Good point .I remember Bill talking about the centripetal pull inward in his book. |
Quote:
For whatever it may be worth here is how I start every warmup on the range (with this subject in mind.) 1. Little acquired motion chip shots with a wedge and just my right hand on the club. You will find that with the right wrist frozen and the RFFW on plane that the bad shots are differentiated from the good by one thing: The lack of #3PP lag pressure. Dont watch the club just think about the #3PP. I sort of walk around hitting random balls continuously, not too much stopping or thinking. Its amazing how easy this is to do and the shots are delightfully pure. Mine is a journey of trying to get this feeling all the way through the bag with two hands on the club. It was this one armed frozen right wrist thing that started my TGM journey in an effort to unlock its secrets and understand its associated fantastic feeling. I knew only of the bent wrist but now know most of the rest of it thanks to Yoda. 2. With the right hands singular job now over I attach the left hand to the grip but let the right hand sort of instruct or direct as to hand position in fix, club path to both arms straight etc. I find that once the left is attached the path problems can start and extensor action , extension becomes problematic and in need of special attention. This is still for me very similar in every aspect to the right hand only procedure but with the passive left arm attached to the grip and serving as a checkrein or rope only. Albeit it with extensor action keeping it taught. My right shoulder moves the club back and thru with rethym maintained (the right shoulder, hands and clubhead moving at the same rpms, different surface speeds) 3. Loosen up with 3/4 wedges and then go back to basic and acquired short shots to wake up the machines precision functions. Sorry for the extra dialogue but hope this helps. If throwaway is a real problem some eyes closed ,no ball, chipping swings can really help you feel the right wrist straightening and loss of PP#3 pressure. The hands are just clamps and with extensor action turned on they dont really have an assignment other than to hang on to the club and send sensory messages back to the brain. Correct me if I am wrong on any of this. That is why I am here. O.B. |
Pump it UP!
OK.... Here's what I want you to do... Go to your wife's sewing kit and get some thread (yard will do), Go to your garage and get a small nail a hammer and a heavy hex nut. Find someplace comfortable and pull up a chair. Take your hammer and tap that nail in to the edge of a table or something (must be open below). Now take your thread and tie one end to the hex nut. Take the other end of the thread in you index finger and drape the thread over the nail.
Now you've got a simple pendulum. Go ahead let the nut swing... notice how the period (TIME IT TAKES FOR A CYCLE TO COMPLETE) changes depending on how long the thread from the nail to the nut is? Now here's what were gonna do. Were going to learn to PUMP IT UP (like Tiger and Saldawski and they all do). I want you to TUG on the string (not much) ... just give it a gentle tug with each osscilation. Tug up as the nut swings down and let it out again as its swinging up.. just little tugs..... Keep repeating. What happens? Thats right....when you do this you're pumping energy into the pendulum... you're making it swing higher with each tug and the club head speed (er.. nut velocity) gets faster. Now do the opposite... Tug up when the nuts is moving up... let out when the nut is moving down. The pendulum slows down doesn't it.... So what h*** does this have to do with golf? Its that old radius thingy (again). You need a shortening swing radius to pump up you club head speed. Have fun with your new found knowledge! |
Quote:
How do you see the best tournament golfers shortening their radius? Is it the extension of the body parts or a simple left shoulder high, right shoulder low or or or ....... Thanks O.B. |
Quote:
![]() They do what they can to pull UP and BACK.. Jamie even is weightless momentarily as he rotates in the air! Incredible. All geared towards getting hands onto the optimal path required to generate maximum club head speed. |
Quote:
What's the optimum path of the hands? Also how much power is there in the shoulders rotating vs. the axis tilt you describe abover? Thanks! B |
Bucket....
I'll have to get back to you on that... But don't hold you're breath short answer is: It depends |
How bout speed, pivot braking, momentum transfer?
I think i hit my best shots with 2 things. aggresive throw of my hip , and braking at around impact fix to release the energy at the right time... |
World Long Drive
I was working with Brian Nash in 2001, when he had his best finish in the Remax World Long Drive Championship. He finished 3rd that year. I was most proud when the commentator at the event introduced Brian and said (approximately), "this guy has the best golf swing out of all of these guys."
The interesting thing was that Jason Zuback, who has won multiple times, didn't make it to the finals that year. I think the grid is 40 yards wide, and he never hit inside the grid. He barely kept the five balls in Nevada. I think Brian hit every ball in the grid in the finals. With the reckless abandon that these guys have to use, it's amazing that they can hit the grid at all. The thing that wins the event is the 1 longest ball. So, they're not very concerned with accuracy. It's a TOTALLY different sport than playing golf. They don't have to play their misses. |
"Wow, there's something in those trees". I'm surprised everyone isn't jumping all over this one - more clubhead speed.
I often wonder how some of the smaller LPGA ladies can hit a ball so far with their smaller frames. There's got to be a secret other than the obvious (tempo, timing, and hitting the sweet spot). I was looking online for any video of women golfers with any characteristics pertaining to this subject. I did run across Juli Inksters: https://thegolfdrillguru.sslpowered....onfodriver.avi She definately does a back heel lift at impact. I wonder if she does this for a particular reason or is it just a quirk in her swing. I just can't believe it isn't for some value. Wali |
I was looking at some LPGA players and saw a video of Juli Inkster with an interesting left heel up at impact.
https://thegolfdrillguru.sslpowered....sterfoiron.avi Could she be using that technique? Wali |

Yes! So does Bubba Watson who can get upwards of 5 degrees angle of attack (when he's really trying to launch one) according to trackman newsletter (forget which one). So does Alexis Thompson http://www.alexis-thompson.com/ who was youngest to qualify for the US open in 2007 (13 yo) |

"Braking" is not in the book. Yoda asked Homer about it. I recall a Yoda post where he mentioned this and said he would get back to us and reveal what Homer said in response.
Dont know if Yoda ever went public with this or not. It didnt make its way into the seventh edition, so you can draw your own conclusions. ob |

Mike Austin talks about a 36 inch right arm and a 6 inch left arm, any views on this?

Around the Horn
Quote:
Of the Body by the Arms and of the Hands by the Club. Not 'Braking'. The come-from-behind winner of the race overtakes the runner-up (who, far from 'braking', is running as fast as he possibly can). Downstroke Pivot Components (Feet, Knees, Hips and Shoulders), having reached their Sequenced 'In Line' Conditions, simply cease their Acceleration. Hence, they are Overtaken by the Power Package Components -- Arms, Hands and Club -- which are still seeking their own In Line Conditions. The popular argument against TGM is "If Homer Kelley had the technology of today, then . . . " The truth is that only now -- some 25 years after his death -- do we have the ubiquitous technology that is proving him right. Despite the misinterpretations of those who command that technology and who would be King. :) |
