Purpose: The purpose of this study was to evaluate the effectiveness of exercise combined with health literacy training on liver fat grade and body mass index in sedentary middle-aged men. Methods: This quasi-experimental study was a pretest-posttest with a control group.  22 sedentary middle-aged man with a liver grade higher than 1 were purposefully selected and randomly divided into intervention (n = 11) and control (n = 11) groups. The subjects in the intervention group participated in the exercise training protocol for 8 weeks along with the health literacy training program, the control group did not have any intervention. Data were collected through liver ultrasound, blood sampling and body mass index measurement before and after the intervention and analyzed using ANCOVA test and SPSS20 software. Results: The results showed that exercise along with health literacy training improves liver fat content and reduces body mass index in the experimental group compared to the control group (P <0% 5). Conclusion: This study showed that performing two interventions of exercise and health literacy simultaneously is effective in improving the fat content of the liver and body mass index of sedentary middle-aged men and prevents the development of advanced fatty liver.

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: 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.
