The purpose of this study was to examine that walking at perceived intensity for older adults. Fourteen older adults (7 male, 7 female; age(mean±SD)=65.6±4.7yr) performed 400m walking test at perceived intensities(slow, normal, comfortable, and fast). The subjects walked at perceived intensities while velocity, heart rate (HR), %HRmax, ratings of perceived exertion (RPE), stride length, and Step frequency were measured. The subjects answered physical response after walking. The main results obtained from analysis were as follows: 1. There were hardly any changes of physiological responses from slow to comfortable. 2. The comfortable intensity was safety pace between normal and fast. And it was easy to find physical responses. 3. The comfortable intensity met the American College Sports Medicine's recommendation for improvement of cardiorespiratory fitness.
