Soccer requires powerful movements of lower extremities. Although the movements of soccer have been extensively studied in kicking leg, there is a paucity of research examining the supporting leg. This study aimed to investigate the influence of the supporting leg on the kinematics during maximal effort long kicking in soccer. A total of 11 male subjects volunteered for the study. They were divided into two groups according to career : 5 healthy male university students in a unskilled group, 6 male university students engaged with soccer actively in a skilled group. Two high-speed cameras operating at 250Hz were used to gather kinematic data, and three-dimensional co-ordinates were constructed using the direct linear transformation algorithm. In addition, pressure measurements were made using a F-SCAN system at 125Hz. The trajectory path length of the center of pressure was different in two groups. This distinction between two groups was reflected in the angular displacement of the supporting leg, especially knee and hip joints. The supporting leg may be also influenced by the action of a flail. Further studies are required on the optimum techniques of the long kicking.
