USBC Press Release - Ball Reaction Study

GREENDALE, Wis. - The United States Bowling Congress has completed its pioneering two-year study of bowling ball motion and how advanced, high-tech equipment may influence lane conditions and scoring in the sport.

The USBC Bowling Ball Specifications Task Force - formed in 2005 and comprised of USBC research engineers and technical volunteers from several bowling ball manufacturing companies - is now analyzing the research data results. The task force plans to meet in February 2008 to discuss the data further. USBC expects to release complete research results to the public next spring.

The goal of the study is to better understand the motion of bowling balls using scientific research and data analysis. As the sport's national governing body, USBC undertook the research working cooperatively with bowling manufacturers. One impetus for the study is that over the past 20 years, bowling's credibility has been compromised in part due to technological advancements that have greatly affected scoring in the sport.

"USBC is concerned that technology has overtaken player skill in determining success in the sport of bowling," said USBC Technical Director Neil Stremmel. "Now that the research phase is complete, the task force looks forward to further analysis and discussion prior to releasing the results to the public."

The testing process officially started in summer 2006 after the formation of the USBC Bowling Ball Specifications Task Force. That group has framed the research project, deciding which bowling ball layouts and lane oil patterns are to be used.

A total of 59 particle and reactive resin bowling balls were used for the research study being conducted in the USBC testing center in Greendale, Wis., which includes eight lanes in a climate-controlled building. USBC's robotic ball thrower - nicknamed "Harry" - was used to roll the test balls. The data was measured using "Super C.A.T.S." (Computer Aided Tracking System) to record the velocity of the bowling balls as they were rolled down the lane. The Super C.A.T.S. system is made up of 23 small electronic sensors installed on the lanes.

USBC engineers and technicians have performed more than 150 tests and have conducted several hundred multiple linear regressions to analyze the data.

USBC is committed through that ball research to maintaining the highest standards for credibility and integrity for bowling. In fulfilling that pledge, USBC is launching a re-evaluation of all components of the System of Bowling, which includes lane surfaces, lane conditions, bowling balls and pins. USBC also has formed task forces to deal with issues and standardization of lane surfaces and lane conditioners/cleaners.

"The ultimate goal of USBC research is to strike a better balance between player skill and technology," Stremmel said.

Can't Hit My Target

When you are attempting to hit between second and third arrow, where do you set your feet before you start moving toward the foul line in your approach?

Always starting on the same spot, will help determine if your missing your target because of drift with your footwork, or a misaligned swing and some funky swing dynamics.

Realizing that you target with your eyes but deliver with your shoulder/arm, determine from your favorite starting position where do you end up? Do you walk nice and straight (sliding and stopping on the same board that you started on)? Or do you drift a little, a couple inches left or right of the board you start on? or maybe just one inch?

Repeat your approach and delivery until you have a solid feel for what is happening. Throw a couple games and record each result. Where did your slide stop? Where did the ball roll at the arrows? Where did the ball go down lane? What pin(s) did you hit first?

From the middle of your body, determine how far over is the middle of your arm? 6 inches? 8 inches? 10 inches? less? more?

If your ball truly does not require grip pressure, it allows a free unforced swing. If you can depend on your swing; you can now aim with your body.

If everything is relaxed and aligned, if you start with your left foot (slide foot for a right hander, assuming right handed) on the twentieth board (middle board on the lane, the board with the center arrow on it, and the big dot on the approach) and the distance between middle of your chest and arm is 8 inches (8 boards over - each board on the lane is an inch wide) your arm should swing straight above the the twelfth board. If you walk up the approach with no drift, you'll slide at the twentieth board, middle dot at the foul line, deliver the ball up the twelfth board, but because you are watching to hit the thirteenth board (between 2nd and 3rd arrow) you might pull the ball just a touch.

Adjust the scenario for your specific tendencies (chest to shoulder 9 or 7 inches, drift a board, drift two boards, when you walk up the approach, left or right?). Once you determine what you do, you should be able to deduce why you miss?

If you drift right (and want to slide at 20, start two boards to the left, on 22nd board) adjust your starting point so you finish at the point at the foul line that you want to slide on/throw from.

The secret to bowling is a comfortable ball fit and embracing momentum and gravity to help deliver consistent shots.

Also, a slight bend in the knees at set-up with back fairly straight and shoulders square should help with balance. When aligned at delivery, the traditional player has head above slide knee, knee above toes. If your mechanics are OK, and without being able to see you throw a bowling ball, we may magically have a way to figure this thing out.

What do you think? Please post questions if you have them. Thank you.
