The purpose of this study was to analyze the throw technique as it related to the technique of the three established field hockey strokes. From this analysis, a description of the throw technique was formulated and compared to that of the push, flick, and scoop strokes. The subject was a female field hockey player who had been a member of the United States Field Hockey Team.The comparison of the four strokes was made from a film analysis of two performances of each, one from the frontal and one from the saggital plane. Ten frames of each performance were selected for analysis. Each sequence was analyzed by the Ball State Computer program "Filmdat." Additional measurements were taken from the film itself to complete the study.From the analysis of data, it was concluded that no consistant pattern of differences in body segment patterns of motion, the angular velocity of each segment could be determined for any of the four strokes. The pattern of percent contribution of the extremities and trunk to total body kinetic energy was similar in all four strokes considered in the study. It was also concluded that the stick velocity, the stick angle at release, the height of the ball at release, and the height of the ball during flight distinguished the push and scoop strokes from the flick and throw strokes. The above data could not distinguish the flick stroke from the throw stroke. The path of the body center of gravity was able to distinguish the scoop stroke from the push, flick, and throw strokes, but could not separate the push from the flick or throw strokes.
