Abstract
This study examined differences as well as relationships among postural control characteristics during a bipedal stance, operating-leg stance, and supporting-leg stance in 10 soccer player and 10 untrained people. The center of pressure measurements were conducted after taking sufficient rest. The subjects were instructed to stand on a footprint painted on the stabilometer while closely looking at a fixed view point in front of them. They were instructed to stand on the stabilometer and to keep a Romberg’s posture with their hands on their waist during bipedal stance, and the subjects were instructed to stand, lifting one side leg before the other side leg during this one-leg stance. In the soccer players and untrained people, the postural control characteristics during standing hardly differ between operating leg and supporting leg stances, but markedly differ between bipedal stance and one-leg stance. The results demonstrated that the soccer players are superior to untrained people in anterior-posterior postural stability during one leg stance.
