The purpose of this study is to consider on slipperiness of floors from a viewpoint of fatigue occurring after long term physical activity. The first, it was cleared that the psychological scales about fatigue which were made by sensory tests corresponded to the slip resistance of floors measured by the apparatus which was developed in previous study. The next, the relationships between fatigue and slipperiness was considered with biomechanical and physiological parameters. As a result, we presented the fact that slipperiness of floor was very important factor and presented the suitable slip resistance from a viewpoint of fatigue.
