Today sport is interrelated to modern urban lifestyles. In order to develop sports and physical activity and promote active lifestyle, three important goals, called the three A, are in attention that the first is to improve accessibility. In this paper by using buffer technique in GIS, the index of per capita access and a descriptive-analytical method Access to sports venues in the 20th district of Tehran has been analyzed. Findings of the research showed that the average per capita access to sports places was 0.6 m2, the maximum was 0.8 and at least 0.027 m2.The access rates is much lower from the global standards and the rates proposed for the Iranian cities But it is somewhat more favorable than Tehran's average. Apart from the general lack of per capita access, many inequalities are evident at the level of the study area. Although the entire area is accessible to sports venues, parts are only accessible to 1 sport place while in some parts the area access of 13 sport places are overlapped.
