The purpose of this study was to examine the relationship between the position of COG and response time on 3 experiment conditions setting right, center and left position of COG with flexing 60 degree angle at hip and knee joint. Six subjects kept the assigned posture on a forceplate until LED signal. After the signal, each subject moved to left or right as quickly as possible. RESPONCE TIME was defined as the interval time from the LEDsignal to kick-foot off (kick-foot was the opposite leg from movement direction). MOVEMENT TIME was defined as the interval time from the LED signal to the time that COG shifted 40% of height form the midpoint of initial second metatarsal in the lateral direction. In the result, MOVEMENTTIME were shortened on condition that COG shifted the position for movement direction.
