International Training and Research Center

You want high tech? Look no further than the USBC InternationalTraining and Research Center-a crossroads between research andcoaching.

These three links demonstrate how the Equipment andSpecifications team are contributing to the ITRC:


Grip and Foot Pressure

The grip pressure system measures the location and amount ofpressure that you impart on different parts of your throwing handthroughout your approach and delivery. A bowler's hand is outfittedwith a specially-designed sports glove with small pressure sensors(0.07 inches thick) attached by medical tape. The sensors areequipped with tiny, individual sensing units that transmit pressuredata from your hand through a data hub worn on the wrist, which isconnected to a computer that analyzes the data.

The foot pressure system measures the location and amount ofpressure placed on various parts of your feet during the approachand slide. Pads with the same type of sensors used in the grippressure system are placed underneath the insoles of your shoe. Asyou approach the foul line, foot pressure is measured and the datais transmitted through hubs worn around the ankles to a computerand then analyzed. Sensors are calibrated based on a bowler'sweight, and the system provides live timing accurate to onehundredth of a second.

Motion Capture

Motion capture is a futuristic-looking suit of lights, similarto the technology that video game makers use to record Tiger Woodshitting a golf ball or NBA star and USBC spokesperson Chris Paulshooting a jump shot to make their game characters lookrealistic.

The USBC motion capture system is sophisticated biomechanicstechnology. Patented by USBC, this futuristic-looking system is thefirst of its kind in the sport of bowling and will be available inthe new USBC International Training and Research Center where itwill be used to identify and correct problems your technique in amore comprehensive manner.

Motion capture measures body positioning and movement moreprecisely than standard video analysis programs. For example, itcan track your body positions (such as during your back swing) to0.001 of an inch, speed and acceleration (such as ball speed or thesliding knee moving forward) to 0.02 mph and timing (relationshipbetween the arm swing and footsteps) to 0.001 of a second.

The system works like this: Between 40 and 70 small sensors areattached to your clothing and six cameras positioned on adjoiningapproaches and lanes that detect the red light reflected from thesensors. Your movements through the approach and delivery aretracked via the sensors and the data is transmitted to a computersystem, and your image appears on the computer screen as a moving,digital data figure that can be shown in slow motion, used withvideo or viewed from different angles.

DigiTrax and BowlersMAP

Coach Ross is also the designer and developer of both DigiTraxand BowlersMAP software programs.

DigiTrax ball motion tracking software measures the accuracy,consistency and transitions of a bowling ball on a lane. The videoanalysis program enables objective (data based) measurements to bederived as it relates to tracking the balls path (from thefoul-line to the pins). The program, which will enable coaches tooffer video analysis capable of up to 1,000 frames per second andsuper slow-motion analysis, captures loft distance, lay down board,launch angle, break point board and distance, entry angle and ballspeed.


BowlersMAP software provides coaches with the ability to analyzestudents utilizing computers and video analysis. Ross designed anddeveloped both DigiTrax and BowlersMAP.
