This study aimed to identify and analyze the factors affecting the athletic commitment to train and compete in the armed forces. The research method was applied, and the study's statistical population consisted of athletes affiliated with the Armed Forces across the country, of whom 290 were selected as the sample. For data collection, in the beginning, the qualitative method and interview with elites were used, then the quantitative method containing a demographic questionnaire and sport commitment questionnaire (researcher-made) with 33 questions is used. The questionnaire comprises six dimensions: facilities, incentives, rules and regulations, financial and personal factors, and enjoyment and satisfaction. Collected data through equation modeling were analyzed using Amos 21 software and SPSS 22 software to identify the factors affecting the variables. The results showed that the research model had a good fit, and a positive and significant relationship existed between facilities and incentives, incentives, rules and regulations, finances, personal factors, and enjoyment and satisfaction with sport commitment. Finally, it is recommended that the physical education managers of the armed forces take advantage of all the national facilities to increase their athlete's athletic commitment.

Background: The traditional approaches to strategic planning in the face of uncertainty of the environment have no inflexibility, and there is no appropriate response to it. Strategic Foresight systems are welcomed by creating a strategy in a highly competitive environment. Aim: The purpose of the study was to explain the effective demographic model of sections quad Iran's sports based on Strategic Foresight to end in 2036. Materials and Methods: The present research is in terms of applied purpose, qualitative nature and implementation path in foresight methods, environmental scanning and survey. The statistical population were faculty members of sports management with associate degrees and higher who were selected by combining sampling. Results: The experts approve the research model with GOF= 0.509. Also, development of academic disciplines in sport for all, land-use planning system in professional sport, per capita family income in championship sport, land-use planning system in educational sport as demographic key drivers were identified. Conclusion: The research model can be effective as a guide in anticipation of the future of sections quad Iran's sports and provided the basis for envisioning the future state and effective decision-making.

Background: The physical fitness is essential for wrestlers to perform successfully. The Tabata Protocol can be appropriate to develop these physical qualities.Aim: This study aims to investigate the effects of high-intensity interval training using “Tabata  protocol” on the physical fitness of teenage wrestlers.Material and Methods: 16 participants were randomly assigned to two groups of Tabata training (n=8) and the control group (n=8). All mentioned variables were measured before and after 4 weeks of the intervention. Tabata training group performed Tabata protocol in 2- 3 sets of 8 exercises with 20 sec of training and 10 sec of rest. The control group kept up their normal training routine during the same time. Physical fitness components were measured. The collected data were statistically analyzed by an independent t-test at a significance level of P>0.05.Results: Wrestlers in both groups significantly increased physical fitness components except flexibility (P<0.05). Tabata training was significantly more efficient in endurance of core muscle (P= 0.019, ES= 0.490) and upper body strength (P= 0.001, ES= 0.490) than control group (P<0.05). Also, results showed that for leg explosive power, only Tabata training had a positive effect (P= 0.026, ES=0.541).Conclusions: Our results suggest that wrestlers after Tabata protocol interventions can obtain better physical fitness, and event time benefits with more efficient performance and time-efficient manner compared with control group.

The current study aims to explain a communication model for quantum leadership, productivity and empowerment of personnel in the Ministry of Sport and Youth using Interpretive-Structural Modeling approach. The research population included all of the personnel in the Ministry of Sport and Youth, and 269 persons were selected randomly as the research sample. The research tool was questionnaires adopted from the literature for collecting the research data. Twelve sport management experts and Cronbach’s alpha method, respectively confirmed the validity and reliability of the questionnaires. SPSS software and interpretive-structural modeling (ISM) approach were applied to analyze the research data. The results indicated the optimal level in the quantum leadership, as well as personnel productivity, and empowerment. Based on the results, an increase in the level of quantum leadership in the Ministry of Sport and Youth raises the level of personnel productivity, and empowerment. In addition, an increase in the personnel empowerment level in the Ministry of Sport and Youth increases the level of personnel productivity.
