Muscle gains and emotional strains: conflicting experiences of change among overweight women participating in an exercise intervention program.

In this study we explored the experiences of women who were classified as overweight while they participated in a physical activity intervention. In line with interpretative phenomenological analysis, eight women were interviewed prior to and following a 12-week dragon boat physical activity intervention. Data were transcribed verbatim and subjected to individual-level content analysis to explore change that informed group-level idiographic analysis. From the idiographic analysis three distinct profiles were created: (a) women who consistently struggled with negative self-perceptions; (b) women who consistently experienced positive self-perceptions; and (c) women who began with negative self-perceptions and developed more positive self-images. These profiles appeared to be associated with age, since the youngest women placed significant emphasis on the body and physical appearance, whereas the oldest participants reported the most significant shift from importance of body to a greater emphasis on health and well-being. The findings, which are reported in the context of self-determination theory, suggest that women in each of these profiles had unique physical and social self-perceptions and distinct social interactions within the dragon boat intervention.
