The present cross-sectional study is the first to investigate the relationship between implicit and explicit attitudes toward different body sizes in female athletes of different sport types. Second, it was examined if these attitudes are, among other factors, related to body satisfaction in these women. In total, 146 female athletes between 18 and 65 from lean and non-lean sports participated in the study, measuring explicit and implicit affective attitudes using pictures of women with different body sizes. Eating disorder risk, the assessment of the image of the own body, and self-compassion were also asked. Results showed that female athletes had more positive explicit affective attitudes towards pictures of individuals whose body sizes correspond to lower body mass indices ranges than higher ones. No differences were found for implicit attitudes. Affective explicit and implicit attitudes for different body sizes showed no significant difference between lean and non-lean sports athletes. Explicit and implicit attitudes did not predict body image satisfaction, but the actual weight-ideal discrepancy, self-compassion, and risk of eating disorders did. Due to the high relevance of body image satisfaction for society and health, future studies should address the aspects of self-compassion and the risk of eating disorders in more detail.
