Body image perception and dissatisfaction in resistance training practitioners: A critical review of the literature of Brazilian studies and assessment tools used.

Abstract

This study aimed to review the findings on body image (BI) dissatisfaction and muscle dysmorphia (MD) in Brazilian RT practitioners and the differences in the assessment tools used. A critical review of studies with searches in PubMed, Brazilian Virtual Health Library, SciELO, PsycInfo, and SPORTDiscus databases was conducted. A total of 23 studies were included. Nine tools were used to assess BI dissatisfaction or MD: three questionnaires and six visual scales. The overall mean BI dissatisfaction was 56.5% (59.2% in men vs 57.3% in women). The mean MD was 42.4% (45.1% in women vs 38.5% in men). BI dissatisfaction and MD are related to women seeking slimness and men wanting to increase muscle mass. In conclusion, the frequency of BI was high in both sexes, and MD, when identified, was higher in women. The scales and questionnaires used differ significantly in depth and scope for the same purpose.
