Abstract: Methods and apparatus relating to predicting outcome in a sporting environment are described. The methods and apparatus are used to relate trajectory performance of an object to body motions and body orientation associated with a generating the trajectory of the object. When equipment is utilized to generate the trajectory of an object, than the effects of equipment motions and equipment orientation can be also related to trajectory performance. The method and apparatus can be used to predict body motions and body orientations that increase the likelihood of achieving a desired outcome including specifying optimum motions and orientations for a particular individual. The method and apparatus may be used in training, coaching and broadcasting environments.

Abstract: Systems and methods are provided for evaluating player performance during a sporting event.
