Along with the economic development, aging of the population and declining birthrates are progressing in some Asian and Western countries. It is becoming difficult to manage the social security system (mainly pensions, medical and long-term care). The extension of healthy life expectancy and the improvement of labor force participation rate of the elderly can be proposed as a solution. The willingness to work and thirst for knowledge of the elderly will be increased by going on a journey and enjoying a sport game. It is said that walking has a high effectiveness for the extension of healthy life expectancy. Walking is a basic action in sport and trip. In this study, an early elderly person is adopted as a subject and the changes of biological information due to walking for 3 years are summarized. It was obvious that walking made a contribution to his health maintenance and the muscle mass was conserved. The number of steps was counted every day using a pedometer. He felt fatigue when the number exceeded 14,000 steps a day and the average number was about 9,000. Therefore, it is thought that the limit number of steps is 12,000 a day. It is necessary to maintain the limit while on a journey. Walking can develop one’s muscle. The circadian period and weekly periodicity of the number of steps were also investigated. It could be examined using the characteristics whether the subject had the usual life or not. In this study, subjective person is only one. However, the purpose of this study is to establish a health care system for the elderly by walking using information technology (smart phone, Wi-Fi and wearable device etc.). The limit steps-number during travelling was evaluated to go on a pleasant journey. It is thought that the result of this investigation could become a kind of guideline for aging society.
