This survey generated a profile of a typical water exercise participant. Data include: (1) subject's medical clearance for water exercise, swimming ability, physical and related problems, reasons for participation and perceived psycho-physical benefits of water exercise; (2) techniques of monitoring water exercise intensity: kinds of flotation devices and supplies used; and (3) participation patterns in about 18 different leisure, fitness and sport activities. The stimulus for in-water exercising among this survey population (n=1,180) was "keeping fit" through all-round body conditioning, which often was accompanied by an increased sense of wellness, relaxation and social interaction. Analysis of the data suggest that different benefits are derived from water exercise for different age groups. Further, the data suggest that water exercise may well be the most important physical activity for older age groups. Recommendations for further study include investigation of water exercise programs for older populations and physical/mental rehabilitation of individuals. (Author/JD)
