Body image as a leisure constraint: Examining the experience of aerobic exercise classes for young women

Abstract

Previous research has shown that women, and especially young women, in this culture experience pressure to be thin. Although considerable research has been directed toward the investigation of body image and its relationship to psychological health and self‐image, the impact of body image on leisure behavior has not been adequately addressed, nor has body image received much attention as a potential leisure constraint. The purpose of this study was to investigate ways in which body image might function as a constraint to young women's participation in aerobic exercise classes. The study used both quantitative and qualitative methods, including a survey of 190 women undergraduate students and in‐depth interviews with a sub‐sample of 11 students. The qualitative data are the main focus of this analysis. The data indicated that body image did not seem to prevent participation or constrain levels of participation in aerobics. Nevertheless, body image concerns were shown to constrain the enjoyment of aerobics as a leisure activity, and this reduction of enjoyment was related to the clothing worn for aerobics and to competition over appearance and body weight among participants. The findings also showed that body image functioned as a constraint into participation in that body‐image‐related concerns were a major motivating factor exerting pressure on young women to participate in aerobics. In sum, the study suggested that body image can constrain leisure in some situations, although it is not a constraint in the traditional sense of preventing participation. The implications of these findings for the conceptualization of leisure constraints were discussed. Furthermore, some practical implications for the provision of aerobics classes were provided.
