Our research aimed to determine if a greater range of motion at the hip joint of the dominant leg full in-step soccer kick would result in a greater kicking velocity. The data showed no difference between the range of motion at the hip joint for the dominant and non-dominant leg full in-step soccer kicks. Therefore, this finding did not support our original hypothesis that the dominant leg would display a greater shank velocity due to greater range of motion at the hip joint. Despite the lack of support for the original hypothesis, the data showed that the dominant leg full in-step soccer kick had a greater shank velocity than the non-dominant leg. The motion of the thigh about the hip joint exerted an inertial force upon the leg causing an increased knee velocity. The greater knee joint angular velocity in the dominant leg suggested that the hip angular velocity would also be greater due to the transfer of inertial forces between body segments. The linear velocity of the ankle joint was also greater in the dominant leg, which also supported the transfer of inertial forces. These findings implied that the increased velocities of each segment in the dominant leg would result in an increased velocity of the soccer ball. According to McLean and Tumility (1993), ball velocity and accuracy determined the quality of the full in-step soccer kick/shot. Follow-through at the knee joint also contributed to ball velocity and accuracy. Knee extension is related to the follow-through of the full in-step soccer kick. The dominant leg reached a much greater maximum extension at the knee joint than the non-dominant leg; thus, it resulted in a greater follow-through in the dominant leg full in-step soccer kick. Many factors limited the results of our study. First, the soccer kick was filmed in an unnatural setting which caused the subject to alter her usual kicking style. The movement took place within a small reference frame in order to film appropriately. The limited space did not allow the subject to complete a full approach. Second, protraction and retraction at the shoulder girdle caused the positions of the trunk segment to be inaccurate. This produced error in the hip joint angle calculations. Third, the full in-step soccer kick involved some internal rotation at the hip joint as confirmed in the study by Levanon and Dapena (1998). This internal rotation, along with speed of the soccer kick made it difficult to accurately identify the joint markers in the motion analysis. Further research into the kinematics of the dominant and non-dominant leg full in-step soccer kicks should emphasize the role of the ankle and foot as well as shoulder and arm motion during the kick.
