Grassroots football is a fundamental and essential part of professional football; therefore, the current research was conducted with the aim of presenting a grassroots football development model in Iran. The current research is applied in terms of purpose and mixed in terms of data collection. In the qualitative part, the systematic approach of grounded theory methods was conducted, and structural equation modeling was used to evaluate and validate the qualitative model. To conduct the interviews, faculty members and sports managers were studied through purposeful approach. In the quantitative part, the research samples included sports managers, coaches and players selected via convenience sampling. Based on the results, causal conditions include factors related to facilities and resources, human resources and managerial factors; context includes factors related to family, education and motivational factors; Intervening factors include economic-political and legal factors; the strategies include human resource management strategies, development of scientific management and coaching, synergy of related organizations and the use of income generation strategies. The consequences include the development of professional football and sustainable development through sports. According to the results of quantitative part, the validity of the research model was approved. the proposed model can be presented as a scientific framework and guidance based on the knowledge of experts for the country's sports managers in line with the development of grassroots football.

Sports facility management is debatable from several angles, such as design principles, safety, and health principles, sizes and standards, and supervision, among which optimal location and determining the appropriate location to build sports facilities is one of the most crucial and specialized categories. The purpose of this research is a review study of sports places site selection with geographic information system. To achieve the research goal, a review study was conducted on the issue of locating sports venues with GIS. Google Scholar, SJR, and SID databases were reviewed to extract English and non-English language articles on locating sports venues with GIS. The researches conducted from 2007 to 2023 were reviewed in this study. The search was conducted in December 2022 and led to the identification of 565 records. After two steps of ‘screening’ and ‘eligibility’, 17 researches have met the criteria and were included for data analysis. Findings demonstrated that GIS has become very prosperous in the world, huge sums of money are spent to prepare these systems, and it is predicted that billions of dollars will be spent in this field in the future.

The present study brings forward a model of workplace health with an approach to staff’s physical activity improvement. this study was an applied and descriptive research that has been conducted with a mixed approach for data collection (qualitative and quantitative). The methodology is performed qualitatively on the basis of grounded theory of Glaser approach. The research participants in qualitative included 18 subjects selected through judgmental sampling method with snowball approach. In addition, the sample in quantitative section, 384 subjects were studied through convinience sampling based on  Krejcie and Morgan table. The analysis in the quantitative section is second-order confirmatory factor analysis. According to the results, components of workplace health comprising the physical environment with sub-components of preparing infrastructure along with strenuous company; the psycho-social environment with sub-components of education, culturalization, encouragement along with support; the health resources with the sub-components of evaluation, supervision and alignment of plans; and participation of the company which comprises management and planning.

The present study is implemented to identify indicators and to provide an optimal evaluation method in recreational-sports pools. The present study is considered practical in purpose, and survey in collecting data. Firstly, by bibliometric research and five professional experts’ interviews, 91 indicators were identified for evaluating recreational-sports pools. Secondly, in terms of 4 components or perspectives in the Balanced Scorecard, 57 indicators were established (internal processes (10 indicators), customer (22 indicators), growth and learning (19 indicators), and financial (6 indicators)), from focal group’s output which was comprised of 4 prominent professors. The structure was confirmed based on 333 individuals’ opinions in the statistical population by employing factor analysis. In order to rate the pools studied, the gray clustering analysis method was applied followed by the structure of the balanced scorecard confirmed. Principally, 20 homogenous recreational-sports pools were investigated in 15 city regions and boundaries of provinces in Isfahan, Sepahan Shahr, and Baharestan. Based on data analysis and rating of each case study, Araman, Absar, Enghelab, Morvarid, and Golsar pools were ranked first to fifth, respectively. Furthermore, the main purpose of the present study based on calculated indicators is to propose a practical method to provide an accurate evaluation of sports pools.
