Barron Associates, Inc. is developing a Personal Health and Fitness Wizard (PHFW) website that will contain all of the functionality needed by U.S. service members and their families to achieve and maintain optimum health and fitness. This effort will leverage the expertise of Barron Associates and Testengine.com in the areas of decision theory and website design, respectively, coupled with the extensive health and fitness knowledge of our other collaborators, Glenn A. Gaesser, Ph.D. and Ms. Anne Wolf, M.S., R.D., to yield an interactive health and fitness package. The PHFW is a complex, adaptive system that fuses an individual's health status, performance parameters, and fitness goals with educational and personal training databases that will work to motivate and encourage users. The Phase II SBIR effort will include the development of the PHFW website as well as its deployment and evaluation on military and civilian personnel.
