Relations among exercise type, self-objectification, and body image in the fitness centre environment: The role of reasons for exercise

Objective: The study aimed to investigate different types of exercise, the role of exercise motivation and body image outcomes within the fitness centre environment. Design and method: Participants were 571 female fitness class participants recruited from fitness centres. They ranged in age from 18 to 71 years and participated in a variety of fitness activities both within and outside of the fitness centre environment. Reasons for exercise, self-objectification, body esteem, and disordered eating symptomatology were assessed using questionnaire measures. Results: Time spent exercising within the fitness centre environment was more highly related to body image and eating disturbance than time spent exercising outside of the fitness centre environment. Participation in cardio-based workouts (e.g., cardiovascular machines) was positively related to self-objectification, disordered eating behaviour, and appearance-related reasons for exercise, and negatively related to body esteem. In contrast, participation in yoga-based fitness classes was related to lower self-objectification and exercising more for health and fitness. Appearance-focused reasons for exercise were found to mediate the relationship between exercise types and self-objectification, disordered eating, and body esteem. Conclusion: The results show that the reasons women have for doing exercise provide a mechanism through which different types of exercise are associated with negative body image outcomes. Thus, despite the physical health-related benefits associated with regular physical activity, exercise motivated by appearance reasons (e.g., weight control) can lead to poorer body image in some women.
