Lack of information about the state of physical literacy has led researchers to examine the state of physical literacy in adolescents in Tehran. Methods: The method of the present study was descriptive and performed in the 12-18 years adolescents in Tehran. The sample was 836 adolescents selected by multi-stage cluster sampling from different areas of Tehran. Subjects 'physical literacy was assessed using the adolescents' physical literacy questionnaire. This questionnaire with three dimensions examines adolescents' physical literacy and has an internal consistency coefficient (0.951) and retest reliability (0.981). Results: The total mean scores of physical literacy in adolescents was 90.04 ± 17.12 and the desired norm was determined with a standard deviation of high and low (107.16-72.94). The results showed that adolescents' physical literacy scores in all dimensions increase with age, also, the scores were higher in boys than girls in all dimensions. Conclusion: Similar results have been reported for differences in gender and age in the Physical Literacy of Canadian children. The norm presented in this study can be a basis for measuring and comparing the levels of physical literacy of adolescents in Tehran.

The purpose of this study was to develop a strategic plan for Pahlevani and Zourkanei federation in Iran. The statistical population of this study included members of the federation's board of directors, chairmen of the federation committees, heads of provincial councils as well as sports and management elites. 50 experts participated in this study through total sampling approach. According to the results of the research, a total of 18 strengths, 30 weaknesses, 12 opportunities, and 17 threats for Pahlevani and Zourkanei federation were identified and based on the internal and external factors, the strategic position of the Pahlevani and Zourkanei Federation in the WT region was determined. A total of 19 strategies, including five SO strategies, five ST strategies, six WO strategies, and three WT strategies for the Pahlevani and Zourkanei federation, were developed. Therefore, according to the results of SWOT analysis matrix, it is necessary to use more than a defensive or stabilization strategy to manage the development of Pahlevani and Zourkanei federation.

The purpose of this study was to investigate relationship between coaching leadership behaviors and burnout (physical and emotional exhaustion, feeling of progression and feeling of unworthy) in male athletes. This was an applied and descriptive study. The statistical population of this research was all male athletes in age range of 18-23 (young). A total of 196 athletes were selected by simple random sampling. The instrument of study included two questionnaires: Raedeke & Smith (2001) Athletes 'Burnout Questionnaire and Chelladurai (1998) Coaching Leadership Report. Their internal consistency with Cronbach's alpha for athletes' burnout questionnaire was 0.765 and leadership behaviors of coaches 0.784. Pearson correlation coefficient and regression analysis and SPSS-22 software were used to investigate the hypotheses. A linear model (structural equation) was used to present the model. According to findings of research, coaches are more likely to use behavioral training and less than arbitrary behavior. There was a significant relationship between behavioral training behavior and all scales (physical exhaustion, feelings of depreciation and reduction of progress), between the authoritarian behavior and physical-emotional exhaustion scales, and feeling of progression reduction in scorpion between democratic behavior and a significant positive correlation scale of progress reduction feeling and bu.

Generally, the music performances on sports activities are manifested and realized through the four mechanisms of reducing the feeling of tiredness, increasing excitement levels, creating harmony, and finally increasing calmness and the sense of comfort. This function becomes very important when considering that the music impact acts as a miracle doping in professional sports. Besides, the lack of enjoyment in sports activities is often mentioned as an obstacle to participation in sports activities. This article discussed, evaluated, and analyzed the research records in three main topics: 1. The benefits of music in sports activities, 2. The conceptual model for showing the different music impact in sports activities, and 3. The underlying mechanisms of music impact on sports. A scoping review of literature in sport and music field was conducted to fulfill the research objectives. Finally, the inference was made by proposing theories such as corresponding and induction of microscopic and macroscopic order along with another direct and secondary music impact. Researches have not been able to uncover all aspects of music magic secrets yet. So, this challenge remains for researchers and athletes on how to maximize the benefits of using music during sport and exercise by focusing on practical applied approaches.

Background : Internationalization of sports leagues can have several benefits, including increased exposure to a global audience; improved competitiveness; and enhanced financial opportunities and cultural exchange. Overall, the internationalization of a sports league can help it grow, become more competitive, and reach a wider audience, leading to benefits for both the league and its fans. Aim: The main objective of this research was to develop a model of challenges affecting the internationalization of the Persian Gulf Pro League (PGPL). Materials and Methods: We conducted twenty in-depth interviews with expertise involved in the functioning of the PGPL who were recruited using a convenience sampling method. The data was analyzed using grounded theory method, including open, axial, and selective coding. During the analysis, we identified 85 codes that generated 49 general concepts. Subsequently, through further reviewing the concepts and their combination with each other, we identified twenty tow final categories that affect the internationalization of PGPL. These categories were classified into five main dimensions: political-economic; managerial; legal; technical-marketing and socio-cultural. Results : According to the research findings, it is necessary for the Iranian football managers and practitioners to first address the challenges affecting the internationalization of the PGPL and then provide the required conditions and platforms with attitude-behavioral alignment to move toward internationalization. Conclusion: The study suggests that Iranian football managers and practitioners need to address challenges hindering the internationalization of the PGPL and provide the necessary conditions and platforms to facilitate the process. By doing so, the PGPL can expand its presence and competitiveness in the global football industry, leading to growth and success.
