TONY LUCZAK'S MASTER'S THESIS ON BEING BETTER AT GOLF

Years of research on the range and in the lab went into this. Understand this and stop wasting time on things that don't matter.

Hey Tony,

Nice intro to your research study. I look forward to reading/hearing more about your research in the months and year ahead. I would like to discuss one aspect of your presentation in which you discussed Jim McClean's X-factor. In your Neuormechanics slide you state a conclusion reached by researchers J Myers et al a:s "Study of 100 golfers show no cause-effect mechanisms that segment separation created additional golf club speed". I have read that report (see Ref 1) and in their final conclusions, as they relate to the X-factor, they state unequivocally:

"Conclusions

A moderate relationship and group differences existed between increased ball velocity and increased torso – pelvic separation at the top of the swing, maximum torso – pelvic separation, maximum upper torso rotation velocity, upper torso rotational velocity at lead arm parallel and last 40 ms before impact, maximum torso – pelvic separation velocity and torso – pelvic separation velocity at both lead arm parallel and last 40 ms before impact. These results suggest that torso – pelvic separation (both maximum and at the top of the swing) contributes to increased upper torso rotation velocity and torso – pelvic separation velocity during the downswing, ultimately contributing to increased ball velocity."

As you can see there is a bit of disparity presented in this report with what you present in your slide and I was hoping you could comment.

Over the last 20 years I have read many of Jim McClean's books, magazine article,s and viewed many of his numerous instruction videos. I recently made a cursory search on the Internet regarding his X-factor swing. In summary, I believe his X-factor golf swing and all of its' multiple refinements since it was first introduced in 1992 are still considered by many today as being a significant contributor to increased swing speed. References 1-5 , links provided below, are just a small few of the many scientific and empirical studies one can find that support this belief. In fact, there are just too many studies available that do not support your statement that McClean's X-factor swing does not contribute to increasing golf swing velocity. May I recommend to you that you change your narrative that the X-factor swing is mere "marketing hype" to something more like it is currently a universally accepted performance-driven golf swing concept and serves as a model in which your studies can build upon. You should create a narrative that your course of study can serve as a complimentary adjunct to McClean's swing concept. Should you decide to continue to hold your belief about his swing theory and express this in journal publication, I fear you will be opening yourself up to a lot of critisism. In this instance you should be better prepared to scientificallly defend your claim. I would not take this approach as I cannot see you winning this battle as evidenced in references cited.

I am also providing links to references 5, 6, and 7 which are for your edification. Interesting reads if your have the time. Anyway, good luck with your studies and I look forward to hearing more good things from your lab. Happy holidays.

Regards,

Derrick

If you look buried in the conclusion is that there is no direct cause and effect mechanism.
