Our overall purposes are to develop new methodologies for the study of physical activity and to provide exercise prescription guidelines for the elderly. Since 2000, we have thus been conducting a longitudinal interdisciplinary study on physical activity and health of the elderly in the typical medium-sized residential town of Nakanojo, Gunma Prefecture, central Japan (the Nakanojo Study). Nakanojo is about 150 km northwest of Tokyo. In 2004, it had a population of 17,942 (8,706 men and 9,236 women), 28.6% of whom were aged >65 years (25.3% of men and 31.9% of women).
