Thats a great observation that will help any readers who are going out there to try the tilted, long ball. I remember my 70's swing had a good deal of double anchor and back pain associated with it.
Im really interested in this elevation, extension thing through the shot. I notice a lot of great golfers doing it and my results have been very good with it. For me its real down then up feeling. The camera doesnt show too much head movement, however in the down direction. I like it but how do we separate this from bobbing? (assuming you subscribe to a little down before the up, maybe not)
How about the authors "twist" as in "jump and twist" the ice skaters jump analogy.
Thanks for this, very interesting
O.B.
I like the jump and twist analogy. Tiger bobs but I never see him hit fat. I think you can do these moves without bobbing. I think you can do a nice amount of thrusting without having your head go back at the end (ie less than Zuback). Look at the knees. Bent in delivery....straight in follow through. Loading into the ground like you were trying to hit low (blow up the plane line). Then, without disturbing the power package, using your legs to get the club out of the ground.

If the right hip is held back in transition and the hips slide forward a la Hogan, V.J. Trolio etc., is it the right hip that does the twisting? Homer assigned so many things to the right side all most as if it was his first choice unless he found out otherwise. This is sort of what I was wondering about in regard to the suggestion that he "he ran his right leg at the ball" it maybe being more of a hip or right hip action.. I dunno. Im really trying to figure it out for me not Hogan but I can sort of see/feel the twist being a right hip action with a corresponding active straightening (but not too full extension) of the left leg. I have a feeling Yoda might call this a hip action too.
How do you see the hip twist, given a held back right hip and the weight left?
I personally think that there is an advantage to flexing the knees like Hogan in the downswing.
When one swings the club down-and-out-and-forwards in the golf swing, one of the three-dimensional forces is a distinct downward force. I think that it's likely that a golfer can better stay in balance - while maintaining all his body/spine angles and while avoiding tippling forward - if he initiates a marked downward thrust force of the club in conjunction with a piston-like flexing of the knees. It is like a downhill skier going through a mogul run - they flex their knees like crazy in order to keep their upper body stable. A golfer wants to keep in balance and keep all his body angles intact during the downswing, and if the golfer has a very forceful down thrust action (like Tiger Woods) then using the knees as shock-absorbers/stabilisers may be biomechanically advantageous. I do not generate sufficient downward thrust to require that type of knee action, but golfers like Tiger Woods and Jamie Sadlowski may benefit by using that type of knee-flex action.
Thanks Jeff, most of the compression occurs during the backswing in that sequence. A little bit more occurs in transition but head height is very still during release...very big pivot driven release...new edit waiting for upload...
I agree that he is flexing his knees during the backswing. Biomechanically, he is still performing the same motion - bracing the knees by flexing the knees so that they are ready to withstand the downward arm swing thrust action movement without losing any body angles or balance. Theoretically, that knee flexing action could presumably occur in the early downswing - just before, and in anticipation of, the downward arm thrust action movement.
Here are images of VJ Singh where it appears that his knee flexing action occurs in the early downswing and not the backswing.
Not all PGA tour golfers seem to need that knee-flex action.
Here are a series of images of Adam Scott. His knee flex angle doesn't seem to change much during his backswing/downswing.
Position 1 and 2 = backswing, positions 3 and 4 and 5 = downswing.

Jeff.
Biomechanically, can one jump higher from a static bent knee posture or down and up motion?
Hogan Power Golf era swing ( I reckon about 1947 - but that is debatable on seperate thread..lets not get off topic )
Foot action , left knee, left shoulder...right knee...right shoulder...
This shows the bit that Ben Doyle "catches the tail " of the dog which he has just let out between his legs.... pretty near cuts the tail off IMO!!
This is the swing where he nearly loses balance... he clearly loved to hit it a long way...
Dog I just realized you are a English bull dog as opposed to most of the Georgia Bull Dogs around this site.
Great stuff, you are fast.
Yes this footage is him really giving it a whack for the camera. Still looks beautiful though , eh?
Two questions I have for all or y'all:
-at what point is this compression a bob and inadvisable? It for sure has implications for the radius as the left shoulder is on the move. Tiger never hits it fat though and I suspect Hogan didnt lay the turf over it too often either, eh Henny? How do they do that, a lot of #1 and 4 left at impact?
-what are we seeing in Mr Hogans hip action in these two photos. It looks like a "jump and twist" as described in the article to me. More curious to me is what is driving this hip rotation or twist? The hips, the right hip, the left hip, the legs , the knees the feet? Im thinking its a hip action of some sort.
OB, have no idea that Georgia had it's own Bulldog! I am British version ...probably equally as inbred though!
I see alot of left leg extension through and just beyond impact (bit like baseball guy that 12PB had)...and left shoulder goes "level left" during COG transfer..then up a bit as hands approach release...then left shoulder goes through the roof through impact!!
Hogan had massive gluteal muscles... look at KOC's recent video
- Hogan's tush juts out way more than the average flabby guy! He is like J-Lo - It may be artifact from all the surgical strapping he was using for his legs... Ok ..probably not... but it looks like the glutes of a 100 metre sprinter .. I think that somehow that is a key component of his swing. I not sure how the biomechanics people will take that but you don't develop that kind of muscle and NOT use ! Glutes are hip extensors i think...that might work.
