Objectives: In this study we examined the relation of team weigh-ins and self-weighing frequency on collegiate male athletes' internalization of body ideals, social pressures about weight/body, body satisfaction, dietary intent, negative affect, drive for muscularity, and bulimic symptomatology. Design and methods: We used a cross-sectional survey design, and collected data electronically from 738 male intercollegiate athletes in the U.S. Results: Athletes who self-weighed 7 + times per week reported the most pressure to lose weight and be lean and muscular, engaged in muscle-building behaviors most frequently, dieted most often, and had the highest level of bulimic symptomatology. Further, athletes on teams that conducted mandatory weigh-ins (vs. not) engaged in more muscularity behaviors and dietary restriction. Conclusion: Weighing, but in particularly that conducted voluntarily, may contribute to an overconcern with appearance, body size/shape, and weight, which in turn can lead to a variety of behaviors related to eating and body change.
