If you have read the Golf Digest (October, 2011), I believe those of you who understand and use the DBS may have some questions or concerns about the crucial issue of balance and, in anticipation of that, I want to present the following ideas. Your feedback is greatly appreciated.
David Leadbetter authored the article, “Use Your Feet to Hit It Further.” He discusses how to achieve a balanced swing but illustrates his points with graphs from technology that focused on pressures in the feet. This is SIGNIFICANTLY different than the updated, advanced information generated by the Dynamic Balance System-DBS.
Why is this important?
As he refers to “balance,” the emphasis is “focusing on how your ‘weight shift’ through the feet.”
- · By definition and how we should refer to “balance,”– “Balance is the ability to control one’s Center-of-Gravity (COG) over the base of support.”
- · The Center of Gravity of the body (even bending forward with the club) is located within the pelvis and therefore this is THE area that needs to be controlled. Movement of the core is sensed or “felt” in the feet. The power center of the swing is the golfer’s core as confirmed by TPI.
- · Platforms that look at foot pressure readings display center-of-pressure (COP) also called center-of-force (COF) graphs. While this may be of interest, it does not show the movement of the golfer’s power center. Because of these differences, I have suggested comparisons of graph results, but have found little interest in the approached companies.
This article says they are illustrating COG movement but this methodology requires additional information, such as height input to accomplish this readout. The DBS identifies COG using computer algorithms developed for NASA. (http://www.sti.nasa.gov/tto/spinoff1996/29.html)
The Dynamic Balance System-DBS measures the deviation of the COG from a known center position on the force platform, with patented microphone use for specifically identifying the very important variable of body position at ball contact!
The use of the foot pressure graphs in this article caught me by surprise as the DBS is in use at Mr. Leadbetter’s facility at Champions Gate, FL.
“We use the Dynamic Balance System as an evaluative tool to begin the vast majority of lessons – we can look at the set up before going into other areas such as swing plane.
The DBS illustrates information the naked eye or 2D video cannot see. By simply talking about the center-of-gravity, it gives us
a great way to help change body motion and swing plane without having to overwhelm the student with too much theory and
information.” Tim Vickers, Leadbetter Academy, Champions Gate, FL
Differences in the Testing Results of the DBS from points in the article:
1. Using the COP system, Leadbetter instructs “at the top (of the backswing), your weight should be fully transferred to your back heel.” The DBS demonstrates that better players, on average, transfer 68-74% of their weight to the backswing side.
2. Next, the article says, “As you swing back…settle into the heel.” The DBS demonstrates that stability on the right leg (of a right handed golfer) should be mid-arch or just slightly heelward. Without the Balance Zone, players can shift too deeply into the heel based on these directions.
3. Most importantly, DBS graphs from tour players and competitive teaching pros (attached) show the body position at ball contact (X) to be in a stronger, more balance position over the left side than in the forward position emphasized in the article. Studies performed on the DBS demonstrate that lower handicap players consistently obtain the same position of weight transfer at ball contact with each club. This fact is emphasized during instruction, club-fitting and specific exercise performance.
ALL FORCE PLATFORM SYSTEMS DO NOT GIVE THE SAME INFORMATION
It was suggested that Mr. Leadbetter may have chosen to use the older COF graphs because he felt the DBS data might be hard to understand by the Golf Digest readers. It has been my experience, that most golfers appreciate and readily understand the specific, verified feedback. Difficulty in reading the DBS graphs has never been a complaint by our users and, to that point, Laird Small, PGA Master Professional at Pebble Beach said:
“The DBS shows our students the movement of their body and balance during the swing, without being too technical….They get it!”

I hope this information is helpful.
