Changes in body image during a resistance training programme for women

Abstract

CHANGES IN BODY IMAGE DURING A RESISTANCE TRAINING PROGRAMME FOR WOMEN. There are conflicting results regarding the relationship between exercise and body image. Most research has been cross sectional and cannot determine if dis/satisfaction motivates exercise behaviours or if exercise participation changes dis/satisfaction for better or worse. Also, it has not been established if exercise influences how accurately we estimate our size and how this relates to perception and evaluation of ideals and others. Furthermore, little attention has been directed towards investigating if body image actually changes and it is not clear if exercise plays a therapeutic or detrimental role. The aim of this study was to: a) investigate changes in perceptual and attitudinal body image and changes in body composition during an exercise training programme for women and b) examine the relationship between changes in physical measures and changes in psychological measures. The treatment group (25 females) participated in a 16 week resistance training programme. The control group (n = 12) did not undertake any exercise (above a recreational level). Anthropometric and psychometric tests were administered at 0, 8 and 16 weeks outside pre- and menstrual phases. The results obtained indicated that 1) for both exercise and control groups, there were significant decreases in skinfold thicknesses but no changes in gross measures such as mass, body mass index (BMI), chest-to-waist ratio (CWR) and waist-to-hips ratio (WHR); 2) both groups demonstrated improved size estimation accuracy, less discrepancy between the actual and self-estimated BMI, increased ideal size and a decrease in the perceptual measure of dissatisfaction; 3) both groups increased the sum of regional satisfaction scores; 4) both groups decreased dissatisfaction measured via the Body Shape Questionnaire and 5) similar to other studies, anthropometric variables explain only a small part of the variability in body image. The study demonstrates that body image, measured by a number of instruments, can change. However, improvements in body image cannot be fully explained by exercise participation or changes in body composition. It is possible that desensitisation to exposing the body during repeated measures, perceived social support of the experimenter or even seasonal factors may have contributed to such changes. Exercise is associated with many benefits but is not evident if it has a unique contribution to improved body image health. It cannot be excluded as a potential intervention but should be tailored to individual motivations.
