The goal of this study was to examine leisure time physical activity (LTPA) among Latina women and to determine factors influencing their LTPA participation. The ecological model was employed as a theoretical framework in order to examine attitudes, social support, and constraints affecting physical activity. Surveys and in-depth interviews were used to collect data. Results showed that although women's LTPA participation was low, they had positive attitudes toward LTPA, and they believed they had high levels of support for LTPA. The most often mentioned constraints included lack of child-care and lack of time. Attitudes toward LTPA, social support for LTPA, and certain constraints were significant predictors of LTPA participation. Results of the in-depth interviews complemented the survey data.
