The purpose of this study was to investigate the differences of ground reaaction force factors between O`Brien style and Torque style in glide moments. Four shot-putters belonged to girls` high school were selceted and measured ground reactinn forces in each case of O`Brien style and Torque style. To measure the ground resistance, AMIT ORG-6-5 Ground resistance measurement instrument and analysis program(Biosoft, ver. 1.0) were used. Measured items were the stance time, Fz maximum deceleration force, Fz maximum deceleration force time, Fz mid stance force, Fz mid stance force time, Fz maximum propulsion force, Fz maximum propulsion force time, maximum torque, maximum torque time, average torque, COP-X, COP-Y, COP length, COP velocity. Average value and standard deviation were calculated on those values measured and were analyzed by t-test method. The conclusion of this study was as follows : COP velocity of Torque style was significantly faster than that of O`Brien style(p<.05), but otrher factors were not shown asignificant differences between two type of glide movement.
