A system and method for improving bowling shot performance based on bowling shot metrics calculated from the analysis of bowling shot sensor data from the user are disclosed. The system comprises a motion sensor/computer device integrated with a bowling glove, a microcomputer system, wireless data communications coupled to methods for data capture from the sensorized glove, and a mobile electronic device for accessing and displaying a bowler's current and historical performance data using the Internet. The performance metrics include ball revolutions rate at release, ball speed, force, backswing duration, front swing duration and shot tempo. Comparing the current and historical performance data allows the user to adjust his or her bowling swing accordingly.
