Abstract
In order to cope with the unprecedented aging society, elderly person need to support themselves and maintain their health. Although there are many electric vehicles such as electric wheelchairs or senior cars, few of them maintain the health of elderly person. They sometimes restrict elderly person sphere of activity of daily living. From such a background, we have developed of four-wheel type electric power-assistant personal mobility for care prevention. In order to check the performance of mobile support equipment, we have experimented for six healthy male subjects using this equipment. The purpose of this experimental is to evaluate the physical load of user by the oxygen uptake values, heart rate and EMG activities while they are running a flat road course and 8% slope. These results can be used for the development of mobile support equipment and evaluation methods.
