Abstract

The purpose of this study was to determine whether or not occlusal force had any relation to power type on anaerobic output. The relations of anaerobic power and occlusal force was tested using 14 alpine skiers（nationally ranked within the top 200）．Anaerobic power and occlusal force were measured at the same time using a Power Max V II stationary bike and occlusal force（dental prescale）．Subjects were then classified as strength type or speed type depending on their power profiles. The range of anaerobic power for the subjects was from 14.28 watt/kg to 14.63 watt/kg which are within the expected range for alpine skiers. Strength type and speed type subjects showed very pronounced differences in their occlusal force tests; strength type subjects occlusal force decreased rapidly during the three stages of the Power Max test while the speed type subjects showed no significant decreases at all. There is significant difference of two group to occlusal force at power max test in three stage（p<0.05）．In conclusion, we found a significant relation between anaerobic power profile and occlusal force. Future studies will be done to generate more detailed occlusal force contact profiles to determine whether or not force values in specific areas of the mouth can be used to determine power type.
