Abstract
The purpose of this study was to explore the possibility of evaluating postural control based on the changes in the center of foot pressure (hereinafter referred to as COP) after doing exercises. After doing treadmill exercise at a variety of velocities, forward-moving distances by running in place and changes of COP over time were measured using normal healthy young subjects. The healthy young subjects showed high values of forward-moving distances by running in place and COP just after treadmill exercise, which gradually decreased. It was found that the procedure varied according to the velocity of treadmill. It was also suggested that the COP value has a different implications from that of usual values. Consequently, it was considered that it is important to evaluate postural control just after exercise.
