The main goal of the three-year Boston Girls’ Sports & Physical Activity Project (BGSPAP) was to create an integrated and sustainable network of community-based programs that use sports and physical activity to favorably influence the physical, psychological, and social development of urban girls. The BGSPAP aimed to provide economically disadvantaged urban girls with opportunities to participate in sports and physical activity. The BGSPAP also aspired to upgrade sports and physical activity programming for girls in order to overcome gender biases built into the Boston schools and community programs. The number and quality of sports and exercise programs for Boston girls were not at par with those of Boston boys (National Women’s Law Center, 2004; Harvard School of Public Health, 2002).
