Doesn't sound like swinging to me though...
 

Surely for the swinger the arms and the hands job is to transmitt CF. To do this surely they need to be relaxed, i would think any muscular effort would be disruptive.

As far as Freddie goes to me he's the epitome of a swinger efficiently transfering CF through relaxed arms and wrists.

Warning
 

I reference my own post...

I have submitted the said research to my friend Mike O and Toolish for review.

With their permission, I will post their comments about it. I am not sure I can post the article sent to them because of intellectual property etc.

As mentioned to them, I stand ready to be corrected in the face of evidence disproving what I sent them. I am here to learn as much as the rest.

Though I may not have all the answers, one thing I know is that once I was short, now I am long doing "my" forearm exercises. :)

One theory that I proposed to Mike is a possible "spillover" effect of my forearm exercises to my upper arms and torso. Not so sure about that...I will post some pictures of the exercises soon.

Thanks to any that will chime in and offer more insights.

The grip tightens significantly (assuming the golfer doesn't have a death grip at address) by the time impact is reached involuntarily so as to stabilize the club. When the club is swinging over 100mph you don't want to have your Great Grandmother's grip on it, otherwise the club would go flying. Most people cannot force themselves to swing faster than their grip strength would allow, doing so would mean the club would leave your hands. Research that was published in Golf Magazine a few years ago indicates that people with more grip strength swing the club faster.

As an aside, I think it is entirely possible that some of Comdpa's swing speed increase came as a result of his grip strength catching up to his ability to apply force with his body. According to Bob Bush's research 70% of a golfer's power comes from the right shoulder. Certainly a person can hit the ball over 30% of their actual distance with just the left arm, but the most efficient way to swing a club is considered to apply most of the force with the right arm and shoulder (my interpretation of Bush's research).

Matt, i agree with what you say about the grip, i think it's very important to have strong hands. Primarily because strong hands means you can have a secure, stable grip and retain relaxed muscles.

In my post i was really talking about how i can't see how strengthing muscles to physically uncock the wrists faster can help a swinger. Also i certaintly don't see how Freddy can be used as an example of a golfer who uses this technique and not his pivot to create power.

I really don't know what my opinion is of working the muscles below the elbow to perform more quickly. This is nothing I had ever thought about prior to Comdpa referencing it. As far as Freddie is concerned, I would argue he is able to swing that quickly, allow CF to increase his swing speed, because he is able to grip the club firmly. This cannot be done without serious forearm muscle contraction. Some of the guys with really fast swing speed and low body fat percentage (Sergio and Villegas are great examples). They have tremendous contraction of the forearms at the bottom. Perhaps the key is to relax the arms and allow the force of the swing to contract them. Perhaps this would provide the Freddie look of being relaxed and being a "slave" to CF.

Sure, In the early 90's Dr. Digby Sale did a study that found for an exercise to increase speed it should meet the 4 laws of specificity.


1.Movement pattern must be exact or as similar as possible to the athletic motion involved. Movement pattern is simple to see. Pulling a rubber band is not as effective as the speed chain in strengthen one’s swing simply because the movement pattern is too disimilar. Rubber band resistance has a linear path, whereas swinging a golf club is a circular, rotational movement on many planes. Same thing with bench pressing or using weights.

2.Contraction velocity must be similar to the event. Velocity is easy to see. Turning with or throwing a medicine ball is very slow in comparison to the swinging of a golf club.
Also, weighted clubs do not meet this criteria simply becuase it cannot be swung fast. Another analogy would be why a sprinter does not train by running marathons.

3.Contraction force must be higher than the event. Force is difficult to measure without the use of high tech biomechanical equipment. But understanding that one needs to overload somewhat to get a strength benefit is logical. The problem arises when one overloads too much and velocity slows down, which in turn decreases the amount of force. This is also the problem with weighted clubs or weight lifting. The weight is so high that velocity cannot be attained.

4.Contraction type must be the same. Contraction type is extremely important since explosive movements use the stretch-shorten cycle. The stretch-shorten cycle is the
short, rapid stretching of the muscles prior to a forceful contraction and is present in all explosive movements. Proper weightlifting techniques discourage this type of contraction.

Kelvin Miyahira (my partner), who was quoted in post #1 invented the speed chain after 25 years of research into this field. Our speed chains defy the laws of gravity by creating a resistance
that moves and retains its resistance along any angle up or down, side-to-side, curved path, linear, or rotation that the human body can produce. This is essential for training the complex movements of a golf swing. Try obtaining that same type of resistance with a rubber band, isokinetic device, pulley system or free weights. Not possible.

Hope this gives you a better idea.

Thanks,

Speed Chain Purchases
 

There have been a number of inquiries regarding purchase of the SpeedChain. LBG is not yet prepared to offer these through its own Pro Shop. However, we have made arrangements for direct purchase through Z2Golf and its principal, Zane Swenson (TrainChain). I've asked Zane to post the purchase details for those interested. Also, we've arranged for LBG members will receive a 10 percent discount on the retail cost (not including shipping). :)

Regarding whether or not the Chain delivers the results promised, I have not been working with it long enough to know if I've gained any additional clubhead speed. I do know that I experience a sense of lag and drag as with no other training aid I've tried. And, I have never experienced the sustained feel of #3 Lag Pressure Point Pressure as deep into the Follow-Through and Finish as I do with the SpeedChain. For me, if these two benefits are all I get out of it, then that is quite enough. They will translate into increased distance, even without an increase in Clubhead Speed (which, if it comes, I will consider a 'freebie').

Yoda,

Will their be a speedchain demo at The Hombre?

I would like to see that bad hombre at the bad hombre!!!

The SpeedChain Cometh
 

You bet, Todd. It's coming in its own truck! :laughing9

I own a swing chain. In fact, it is my second since I upgraded to a heavier size. When I began using it about a year ago, my swing speed was 96 mph and would sometimes top 103. Now, my swing speed is 105 and will sometimes top 111. This is the only training device I use. I love it.
