The purpose of this study was to examine factors that influence exercise maintenance in an older population using the self-regulation of exercise maintenance model which focuses on the individual's personal meaning or interpretations of exercise. This study was the second of two phases. The aims of Phase I, the preliminary descriptive phase, were to identify qualitative descriptors of episode-specific interpretations of exercise in women, 60 years of age and older, immediately after an exercise episode. These qualitative descriptors were used to develop an instrument to measure episode-specific interpretations of exercise for the present study, Phase II. In Phase II, instruments that measure general and episode-specific interpretations of exercise were administered to older women (55 years of age and older). The primary aims of this phase were to evaluate the psychometric properties of the newly developed instruments measuring episode-specific and general interpretations of exercise and examine the contribution of episode-specific interpretations, a component of the self-regulation of exercise maintenance model, to the understanding of exercise behavior. Also in Phase II, a fitness subsample of older women were recruited to examine the relationship between self-reported exercise behavior and physiologic indicators of exercise behavior (estimated maximal oxygen consumption and body composition) and examine the relationship between ratings of perceived exertion and heart rates of older women. Results showed that episode-specific interpretations of exercise accounted for an additional amount of variance after the effects of age and general interpretations of exercise were removed. Self-reported exercise behavior was slightly, and at best only moderately, related to estimated maximal oxygen consumption. Body composition was moderately related in the expected direction to self-reported exercise behavior. Finally, correlations between perceived exertion and heart rates of older women, for the most part, were strong and positive (the expected direction).
