"They are men, they will be looking even if you put on pants or a sweatshirt": Girl athletes' and coaches' experiences of body image in Mexico City sport settings.

Body image concerns are a barrier for girls' participation in sports. Scarce evidence from Mexico suggests adolescents experience high levels of body dissatisfaction, and national statistics report low levels of physical activity among girls. This study aimed to explore girls' body image concerns and coaches' perceptions of girls' body image experiences in sport. We used reflexive thematic analysis on secondary data from semi-structured focus groups conducted in Mexico City with 12 girls aged 11-17 years and six coaches from two sports organizations. Girls expressed feelings of self-consciousness about their performance, body-related teasing, the male gaze, and harassment within and outside sports contexts. Lack of support from coaches resulted in making excuses for withdrawing or supporting one another. Coaches' accounts demonstrate gender stereotypes about girls in sport. They acknowledge that girls abandon sport because of appearance-related teasing and body image concerns. In addition, colorism and discomfort with speaking directly about bodily functions are fundamental sociocultural influences affecting their communication. This is the first qualitative study exploring girls' body image concerns and coaches' perceptions of such concerns in Mexico City. Further research in lower- and middle-income countries is key in developing effective intervention programs to help girls benefit from sport.
