With the arrival of an aging society in Japan, accidents among elderly people involving falls and bone fractures are on the increase. Efforts to prevent such accidents are strongly required, so the concept of a "fall and fracture prevention school" is spreading. The aims of these classes are to make elderly people aware of the condition of their bodies and to improve deteriorating physical ability through exercise programs, since the latter is the cause of such falls. In conducting an exercise program for the elderly, it is important to make it enjoyable as well as safe.
