Editor’s Note: In its Professional Applications section, the Journal of Aging and Physical Activity occasionally publishes descriptions of state-of-the-art clinical or research programs in order to provide JAPA readers with background information on the aims and objectives, organizational structure, and administration of these programs. In this issue, the history, aims, and key programs of the Fifty-Plus Fitness Association (FPFA), which has served the Palo Alto, California, community for the past 20 years, are described. Program directors wishing to submit information about their clinical or research programs for consideration for inclusion in the Professional Applications section should contact the editor.
