Given the importance of desert sports in the development of sports tourism in desert areas, the purpose of this study was to assess the effect of destination image on satisfaction and revisit the intention of desert sport tourists in the Lut desert of Iran as a desert sport destination. The research population was sport tourists who had visited the Lut desert (in Iran) in 2020. 208 valid and reliable questionnaires were distributed among the research samples that were selected through a convenience sampling approach. The model validity and the relationships among research variables were verified by using structural equation modeling with PLS. The research findings demonstrated that destination image of a desert sport destination has influenced desert sport tourists’ satisfaction and their revisiting intention. Moreover, tourists’ satisfaction had a significant effect on tourists’ revisit intention. The findings of this study can lead to a better understanding of behavioral mechanisms that can provide reliable principles for maintaining and developing sport tourism in desert sport destination destinations.    

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. 

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.

Background: Regular exercise has been shown to have a positive impact on both physical and mental health. There is growing evidence to suggest that exercise can improve mood, reduce symptoms of anxiety and depression, and increase overall well-being. Aim: This study aimed to investigate the role of ethical values and coaching styles in adherence to sports in group and individual athletes. Materials and Methods: The statistical population of the present study included 350 athletes in group and individual disciplines in Mashhad, 296 of them were randomly selected as a statistical sample. Descriptive and inferential statistics were used for statistical analysis in the present study, which was done using SPSS 23 (Chicago) and LISREL 8.80 software. Results: The results of the Kolmogorov-Smirnov test showed that the research data have a normal distribution. The analysis results showed a significant relationship between coaching style and its components with adherence to sport and between ethical values and its components with adherence to the sport. Also, the regression analysis results showed that ethical values and their components and coaching styles and their components have the ability to predict adherence to the sport. Conclusion: Finally, it was found that the structural equation model of the relationship between ethical values and adherence to sport and coaching styles and adherence to the sport has a significant fit. According to the results of the research, it can be said that coaches and those involved in sports can, by properly explaining and presenting ethical values, as well as the correct use and application of coaching styles, encourage people in the community at all levels and especially athletes to adhere to physical activity and exercise.

Background: Balance is a critical physical factor for achieving independence, and children with spastic cerebral palsy often experience motor and balance difficulties. Aim: The aim of this study was to investigate the effects of game therapy on the balance of children with cerebral palsy, with a focus on basic abilities. Materials and Methods: This study utilized a quasi-experimental design with a pretest-posttest controlled approach. Twenty children aged 4-10 years, diagnosed with spastic diplegic cerebral palsy with levels 1 and 2 according to SCFMG standards, with a minimum IQ of 80 (to be able to perform the required tasks), and possessing the basic ability to stand and maintain posture balance, as well as communicate and understand linguistic concepts, were randomly selected from rehabilitation clinics in Tehran. Subjects were randomly divided into the control and game therapy groups. The pediatric balance scale (PBS) test was used to evaluate the balance level using a WII device with a wireless controller and a motion controller. The exercise program consisted of nine different games targeting various areas with the common goal of improving the child's balance. After 20 game therapy sessions, (four 20-minute sessions per week,) tests were repeated in the post-test. The data were analyzed with tow way ANOVA Test and paired T-test by SPSS, 20. Results : The results of the paired t-test indicate a significant improvement in static balance in the post-test for the game therapy group when compared to the pre-test ( P <0.0001). Moreover, the dynamic balance of the experimental group showed a significant improvement in the post-test when compared to the pre-test ( P =0.042). Conclusion: The study findings indicate that game therapy is a viable method for enhancing both static and dynamic balance in children with cerebral palsy. Given that the games used in the therapy are intended to be played at home with parental supervision, it is advised that these games be utilized to improve the balance of children with cerebral palsy.

Background: Sports facilities are one of the most commonly used services in the city with a significant role in improving the physical and mental health condition of citizens thus a proper procedure is required to locate and distribute them. Aim : The purpose of this study is to design a comprehensive model for the optimal location of sports facilities. Materials and Methods: The research method is descriptive-analytic based on information gathering and is applied research based on objectives. The opinions of 20 experts have been used to design the model using the Delphi method, and weighting the effective criteria in the sports facilities location. The weight of each criterion has been obtained as population density (0.47), access (0.31), development potential (0.14), and adjacency (0.08); furthermore, the Kendall coefficient of concordance (0.74) in the third step of the Delphi method shows the strong agreement between the experts, regarding the proposed model. The proposed model consisted of six steps: 1. Aim; 2. Verification of the functional area of the existing sport facilities and specific restrictions of the area; 3. Introducing and weighting the important criteria in the sports facilities location; 4. Identifying the most suitable locations for constructing the sports facilities; 5. Evaluating the needs of users; 6. Selecting the best spaces and prioritizing them. Results: The results of the model showed that the most important criteria for locating sport facilities are population density, access, development potential, and adjacency. Additionally, it was indicated that the agreement between the experts increased over time. Conclusion: According to the proposed model, it is possible to identify the points that are suitable for constructing the new sports facilities.

Background: Telomerase activity plays a key role in preserving telomere length which is important in cellular aging. There is evidence showing the link between sirt6, irisin, and telomerase activity.   Aim : The aim of this study was to compare the effect of 8 weeks of high-intensity interval training (HIIT) and aerobic continuous training (ACT) on telomerase activity, sirt6, and irisin levels of healthy older adults. Materials and Methods: Thirty healthy males (age: 60-70 years, weight: 68-72 kg) participated voluntarily to follow the 8-week program including 3 sessions per week. Rest ratio in HIIT training was 1:2 and the intensity corresponded to 90% of HRR. ACT intensity was progressive starting with 50% of HRR and finishing with 70% of HRR. Blood samples were taken in a 12-hour fasting situation, before and after the program. Results: Results showed a significant effect of training on serum telomerase and sirt6 in training groups, not the control group. Also, in comparison to ACT and the control group, serum irisin was significantly higher in the HIIT group. Conclusion: We concluded HIIT training is safe and efficient for older adults in terms of telomerase activity, sirt6, and irisin level and can be followed as a time-efficient training protocol.
