Grip and Foot Pressure

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

The foot pressure system measures the location and amount of pressure placed on various parts of your feet during the approach and slide. Pads with the same type of sensors used in the grip pressure system are placed underneath the insoles of your shoe. As you approach the foul line, foot pressure is measured and the data is transmitted through hubs worn around the ankles to a computer and then analyzed. Sensors are calibrated based on a bowler's weight, and the system provides live timing accurate to one hundredth of a second.
