 note = {To investigate the optimal defensive posture at basketball, focusing on the reactivity of the body, we evaluated the movement speed and reaction time by the various postures with different hip and knee joint angle. Nineteen female students with the basketball career for 7-12years between 18 and 23 yrs of age were recruited for this study. We used the four postures with hip and knee joint angles of 30 and 30 degrees (30・30), 70 and 70 degrees (70・70), 30 and 70 degrees (30・70), and 70 and 30 degrees (70・30), respectively. Subjects performed each three trials of step as quickly as possible to the left and right direction at the four postures. It were measured that whole body reaction time, muscle reaction time, latent time and maximum floor reaction force estimated from vertical force signal, and first step width and initial velocity of body trunk estimated from twodimensional video analysis. There were no marked difference in the whole body reaction time, the muscle reaction time, the latent time and the first step width in step performance of all posture. On the other hand, the initial velocity of body trunk with 30・30 posture was significantly fast as compared with 70・30 and 70・70 posture (P<0.05). The maximum floor reaction force with 30・30 posture was significantly high as compared with 70・30, 70・70 and 30・70 posture (P<0.05). These results provided the obvious evidences that the posture with hip and knee joint angles of 30 and 30 degrees had the advantage in initial velocity of body trunk and maximum floor reaction force during side stepping.},
