This study aimed to identify the consequences of exploiting renewable energy sources in football stadiums. The present study was qualitative research, and the qualitative content analysis method was used to analyze the data. The statistical population of the present study included experts in sustainable development, managers, and technical engineers of the stadiums where the Iranian Football Premier League was held in the years 1398 to 1399 Iran. Access to research samples was done by purposeful sampling method and then continued by snowball method. Finally, after conducting interviews with 12 people, theoretical saturation was obtained. After collecting and analyzing the interviews, 44 open codes were obtained, divided into ten pivotal categories. Finally, from the obtained categories, three concepts of environmental management (pivotal categories of reducing environmental risks, managing energy resources, managing pollution, and improving energy consumption patterns), Improving the social and cultural situation (pivotal categories of improving social attitudes, the quality of welfare services and urban beautification), improving economic status(pivotal categories of Reducing organizational costs, promoting the brand of the stadium, generating organizational income) were obtained. Finally, considering the environmental crises in the world, such as water and energy crises, air pollution in megacities, and the effects of sports on the environment and vice versa, it is suggested that the government, policymakers, and sports managers provide the necessary grounds for exploitation of renewable energy sources such as solar and wind energy in football stadiums, take positive actions for sustainable development and carbon-free sports.

The purpose of this study was to compare emotional investment in the body and social adjustment of male athletes and non-athletes in the second year of elementary school. The research method was descriptive-comparative. The statistical population included male students of the second year of elementary school in Tehran in the academic year of 2019-2020, of whom 206 were selected as a sample by random cluster sampling. To collect data, two questionnaires were used. The face and content validity of the questionnaires were confirmed by experts and their reliability was obtained using Cronbach's alpha of 0.80 and 0.98, respectively. There was a significant difference in the level of emotional investment in the body and social adjustment between the mean scores of athlete- and non-athlete students. In addition, the average score of social adjustment in students who practiced group sports was higher than students who practiced individual sport. The results of this study emphasized the need to use group sports activities for the development of students in terms of family relationships, school relationships, templates, skills, social relationships and attention to the important role of sports in students' perception and feeling, comfort, care and protection of their body.

The purpose of this study was to identify green requirements and actions for green management In relation to the sustainable development of Iranian football stadiums.

The statistical population of the present study included experts in the field of sustainable development, managers and technical engineers of the stadiums where the Iranian Football Premier League was held in the years 1398 to 1399 Iran. Access to research samples was done by purposeful sampling method and then continued by snowball method. Finally, after conducting interviews with 12 people, theoretical saturation was obtained. After collecting and analyzing the interviews, 42 open codes were obtained, which were divided into 10 pivotal categories. Finally, from the obtained categories, three concepts of environmental management (pivotal categories of green development, green space development, pollution management), energy resources management (water resources management, electricity management, gas resources management), social and cultural management (categories of social conflict management, justice and civil rights respect, charitable activities, culturalization) were obtained. The results of this research can be used in the construction of green stadiums based on sustainable development. in addition to this, ,the result of this research can also be used in the policy making and creating strategical program of sustainable development in the country sport.

This research aims to prioritizing new usable technologies in sports facilities with an emphasis on reducing energy consumption. Mixed research method (qualitative and quantitative) has used in this study. The population of the study was 50 of experts that had studies in areas of sport facilities, energy engineering, Civil Engineering and the environment. Sample was equal with population. In the qualitative section, qualitative interviews have conducted with 11 experts. In quantitative section, AHP researcher-made questionnaire by Behingostar software have used to data collection. Findings of the qualitative analysis showed that the new usable technologies used in sports facilities with the emphasis of the reduction of energy consumption have divided into the three main indexes of the new technologies reducing water (6 item), power (9 item) and Gas (9 item) consumption. Building management system was the most important technology in reducing power and gas consumption (relative weight 0.30 and 0.29) in sport facilities. Future bath showers (relative weight 0.32) were most important technology in reducing water consumption. Therefore, due to the limited availability of energy resources in the country, managers of sports facilities have to step in order to benefit these technologies to develop sustainable sports facilities in the future.
