There is no energy stored when muscles are stretched. Muscles contract... thats what they do. When muscles contract they apply forces to levers (the human skeleton) which cause movement. Thats all.

Muscles contract (apply force) to levers... thats it! Thats what muscles do.

Geez you make it sound so simple. Muscles contract and apply force to levers. But like most things it isn't that simple. Muscles require chemical reactions to contract. They can contract in many different ways - different speeds, different levels of power, different lengths. They are also connected to ligaments which react differently depending on the amount of tension they are under.

And I am sure I don't need to tell you about potential energy in a kinetic system, and that the sorts of actions biomechanic is talking about create and release potential energy, converting it into kinetic energy through a chemical reaction, initiated by an electrical impulse. Newton would have no concerns that in creating a level of stretch between two points connected my muscular tissue that this creates a level of potential energy that is released and realised when the muscles contract.

BTW this is in the same class as Homer teaches whereby the four power accumulators store potential energy.

Sure Angular momentum "applies" in golf.... But Angular Momentum sure as heck is not CONSERVED in the golf swing (for the reasons I've already stated several times now). If angular momentum were being conserved in golf as a theoretical golfer spun about his/her theoretical spine axis then as the club moved away from the body.... THE ROTATION OF THE SYSTEM WOULD SLOW DOWN. COAM dictates that an Increase the moment of inertia must be accompanied by a rotational speed decrease. Everyone knows that does not happen. Everyone knows the club angular velocity speeds up as it releases and Nesbits data proves not everyones (probably darn few) hands slow down prior to impact. COAM like COM in describing the golf swing is a MYTH (one of many btw).

I'm saying what you have written in this thread is wrong.... Don't go trying to drag other's to your defense. That is a blatant logical fallacy (appeal to popularity)... in this case a popular misconception.

Like using Nesbit's research? Like saying "Everyone knows"? Angular momentum can be conserved in the sense that it isn't wasted. An example is the need to create and sustain Lag. What biomechanic is teaching is how to conserve the momentum and not allow it to dissipate early so that as much of what you generate when you push against the ground can be applied to the ball. What is important to remember is that the only energy (and kinetic energy (like momentum) is energy) you can generate to power your swing comes from you pushing against the ground. The conservation comes in getting as much of that energy into the ball to send it on its way. There is no other energy available because every action has an equal and opposite reaction and all of that opposite reaction for your golf swing either goes into the ground or is wasted (at least in the sense of maximising clubhead speed) as two parts of your body act in opposition.

Every golfer wastes the energy that is created when they push against the ground. biomechanic trains you to waste less of it. And that's the sort of conservation that I want in my swing.

YOU SHOULD CARE ABOUT THEORY! Let me tell you a true story. There was once a project to which a young Engineering graduate was assigned. They had a pit of water about 60 feet deep that need to be drained so construction could begin.... The forman on the job had a lot of "practical" experience and ordered that a certain pump be used. The young engineer took one look at the pump and said it would not work. The forman was an arrogant man who thought he knew more that some young punk engineer fresh out of school with nothing but some "book learnin". In the end the engineer was proven right... Even though it was a very big pump it did not work. do you know why? Anybody? "Theory" tells us why.

Bio.... Your words sound nice ... very benevolent... But I believe Ayn Rand has you pegged... you're in it for selfish purposes... All business' are in it to make money. Again... I'm listening... WHERE IS THE BEEF?

biomechanic did not say that the theory did not matter - he said that he didn't care about it because the theories that his work is based on have been tested and demonstrated to be effective (that's what it means when he says that In our field you don't last long in the game if your theories are flawed and don't get results. Taking words out of context is another of those logical fallacies:

The practice of quoting out of context, sometimes referred to as "contextomy" or "quote mining", is a logical fallacy and type of false attribution in which a passage is removed from its surrounding matter in such a way as to distort its intended meaning.

To criticise someone in business because they want to make money is not reasonable. Lynn and Ted make money out of golf - are you criticising them because they post here? Because they set up a forum to "suck us in? And if you think I am here just to support biomechanic, I became a member here before I ever even knew he existed. However he has helped my game, so I am happy to share what I've experienced. I've seen a little of the research and unique tools that biomechanic has. I know some of the background of the people he works with. And I am seeing the results in the air and on the scorecard.

And I have seen the numbers that show how the different parts of my body accelarate and decelarate through the swing. And I have seen the numbers for a world number one golfer, renowned as possibly the best ballstriker ever. Not numbers from video pinched off the net. Numbers from a screening exactly the same as I got. I can see the accelaration of body parts and the clubshaft and the clubhead. I can see the decelaration (and yes Daryl, they decelarate after they pass line of sight). Biomechanic was able to show me exactly where I was throwing it away. How my bosy was trying to support a swing that was basically all arms. And his exercises have changed that enormously since then. Now I compress instead of scoop. Now I pivot to drive the swing instead of just to give my arms some support while they try and do all the work. Now I don't come away from the golf course or range with painful hips and back for days.

That is why biomechanic says that he doesn't care about the theory. He's not here to educate you on why this stuff works. He's here to say that he has a way that will improve your zones (not just your pivot), imrpove your power delivery, and will make you a healthier golfer.

I'm glad I listened.
