Drawing on feminist, poststructural, and critical theories, the purpose of this research was to understand 5th-grade girls' self-identified barriers to physical activity and work with them to find ways of negotiating those barriers in order to increase their physical activity opportunities. We worked with 11 girls in two elementary schools in southwestern United States. Data were collected over the 2005-2006 school year. Data sources included (a) 23 transcribed audio recordings, (b) field notes, (c) planning notes, (d) task sheets, (e) artifacts created by the girls and the principal investigator, and (f) photos the girls took. Our interpretations are presented in two sections. First, the girls explained that being a "girly girl" hindered their activity participation because a "girly girl" does not want to "sweat," "mess up her hair and nails," "mess up her nice clothes," and sometimes wears "flip-flops." Second, we discuss how we and the girls created a curriculum of possibilities that culminated in developing a book of physical activities that girly girls would enjoy. (Contains 2 figures.)
