Research Abstract	Anterior pelvic tilt angles of faster sprinters during foot strike and toe off were significantly larger than those of slower sprinters. The faster sprinters also ran with a significantly higher leg swing angular velocity during contact phase compared to slower sprinters. In addition, the average leg swing angular velocity was found to have a significant correlation with the anterior pelvic tilt angles and pelvic rotation angle, respectively. These results indicate that the pelvic kinematics were one of the factors to produce higher leg swing angular velocity for running.
