Abstract

INTRODUCTION: If you are a defensive player of football or basketball, you must have an experience that you were impotently left behind the offensive player while you certainly knew he/she cut back to left and you should have stepped to left. Why this happen? As a basic research to answer this question, we conducted the lift-one-leg task from quiet standing with and without visual feedback of weight distribution. We hypothesized that the time to lift leg depends on the initial weight distribution. The aim of the present study is to investigate if and how much the initial weight distribution during quiet standing influences the time to lift leg.
