The purpose of this study was to investigate the effect of strategic thinking skills on the effectiveness of strategy creation process of team sport federations in Iran. 57 questionnaires distributed among the managers of team sport federations to collect the required data. Strategic thinking skills questionnaire and effectiveness of strategy creation process questionnaire adapted from Moghimi and Ramezan questionnaire (2015). Structural equation modeling with partial least squares (PLS) approach was employed for data analysis. The results indicated that strategic thinking skills of managers had a significant effect on the effectiveness of strategy creation process in team sport federations. According to the findings, improving the strategic thinking skills of managers in sport federations, is critical in the process of creating effective strategies.

Introduction: The aim of present study was to determine the effect of biofeedback training on electrical activity of trapezius muscles and range of motion in people with shoulder impingement syndrome. Martials and Methods: In this study, 20 patients with shoulder impingement syndrome in age range of 20-40 y were selected as the statistical sample and were divided into experimental (n=10) and control (n=10) groups. The experimental group trained by using EMG biofeedback for 8 weeks and 3 sessions per week. The control group was applied only for pre-test and posttest measurements. For data collection, surface electromyography was used to analyze the muscle activity patterns of trapezius muscles (upper, middle, lower), and a goniometer was executed to evaluate the flexion. Shapiro-Wilk test was used to confirm the normality of the data and covariance analysis test was applied to compare pre-test and post-test. Correlated t-test was used to examine within-group changes. Results: In this study, after 8 weeks of biofeedback training in the experimental group, a significant improvement in the electrical activity of the middle trapezius (P=0.000) and lower trapezius muscles (P=0.016) was observed. In addition, a significant improvement in the amount of flexion range of motion (P=0.000) was indicated in the experimental group compared to the pretest and also the control group (P=0.05). However, no significant difference was shown in the muscle activity of the upper trapezius muscle (P=0.776). Conclusion: The present study showed that biofeedback training is effective to improve the electrical activity of trapezius muscle and flexion in people with SIS.

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.    

Psychological commitment has been to date one of the interesting research topics in sports psychology. To achieve a deeper understanding of sports fans' psychological characteristics, this study aimed to design a qualitative model of the factors affecting psychological commitment in football fans in Iran based on grounded theory approach. In this qualitative-analytical study, 27 experts in the field of sports and fan loyalty in the Iranian Football Premier League from the top universities in Iran were interviewed based on purposive and triangulation sampling approach. The data analysis was also performed by open and axial coding, of which 53 concepts and 11 categories were classified under five general themes. The developed research model consisted of five major effective factors including: triggers, psychological characteristics, demographic characteristics, reference groups, and club-related issues. The results revealed that such factors could be the main actors shaping sports fans' psychological commitment.

Background: The coaching styles are a powerful force that can affect the health of athletes and their view of sports. Aim : The purpose of this study was to investigate the relationship between Coaches' Behavioral Style (CBS) and Exercise Pleasure (EP) and Athletes' Moral Health (AMH). Materials and Methods: This research is descriptive-correlational. The statistical population of this study included all athletes in Neyriz city. Three questionnaires were used for data collection: CBS questionnaire of Chelladurai and Saleh (1980), EP questionnaire of Scanlan et al. (1993), and AMH questionnaire of Vallerand et al. (1996). Descriptive statistics and the Spearman correlation coefficient were used for data analysis. Results: The results showed that although some of the components of AMH and CBS, such as negativism, were inverse, overall, there was a positive and significant relationship between CBS and AMH. Also, there was a positive and significant relationship between AMH and EP. Conclusion: According to the results, CBS can affect AMH and EP. Therefore, sports coaches should choose their behavior style according to athletes' needs, however, based on their willingness in supportive and participatory styles

Background: Taekwondo is a traditional Iranian martial art currently practiced in over 206 countries around the world. Aim: The present study aims to provide fundamental information on injuries in Iranian elite Taekwondo athletes. Materials and Methods: A total of 200 Iran Taekwondo national team athletes (means±standard deviations: Age: 28.8±10.7 years, Height: 175.7±9.2 cm, Weight: 69±14.7 kg) participated in this retrospective study. The data was collected based on the injury surveillance system during 2021. The questionnaire included personal information and Taekwondo-related injuries information. Data was illustrated using descriptive methods and was analyzed using the Chi-Square test ( P <0.05). Results: The overall injury occurred during training was more than competition ( P <0.05). The occurrence of acute injury was higher than chronic ( P <0.05), and the most prevalent types of injuries were strain, rupture, and muscle spasm. The number of injuries that occurred in the lower extremity was higher than in other parts ( P <0.05), and the knee was the most vulnerable joint ( P <0.05). The most important cause of injuries was fatigue ( P <0.05). The non-contact injury was the most significant injury mechanism ( P <0.05). The severity of injury in Iranian elite Taekwondo athletes was high ( P <0.05). Conclusion: It can be concluded that injuries during training were more than competition, acute injury was more than chronic, strain was the most common type of injury, and the most vulnerable joint was the knee. Fatigue was the leading cause of injuries in elite Taekwondo athletes. So, in designing an injury prevention program, these factors should be considered.
