The aim of the current research was to investigate the behavioral intention of coaches in virtual reality with considering the roles of Perceived Usefulness, Enjoyment, Performance Expectancy, Self-Efficacy, and Ease of Use. To collect the research data, a researcher-developed questionnaire with two sections was used. The first section included participants' demographic information, and the second section was used to collect data on research dimensions and variables. All questionnaires in this study utilized a 5-point Likert scale. The statistical population of this research included all sports coaches in Guilan province, Iran, both in individual and team disciplines, with a sample size of 350 individuals. SPSS software was employed for descriptive statistics, and Smart PLS was used for structural equation modeling. The results indicated that perceived usefulness, self-efficacy, enjoyment, ease of use, and performance expectancy have a positive and significant impact on the intention towards virtual reality behavior. Considering the current findings, the use of virtual reality in sports coaching can be recognized as a powerful tool for enhancing athletes' learning experiences, increasing enjoyment, and fostering a stronger and better inclination for active participation in sports activities.

Dynamic environments provide sports organizations with various threats and opportunities for optimization and development. This study aims to examine the effect of dynamic capabilities on organizational performance with the mediating role of ambidexterity and digital platforms in the Tehran Municipality Sports Organization. This practical, developmental, and quantitative study was conducted at the Tehran Municipal Sports Organization in Iran. A total of 213 questionnaires were obtained through Google Forms and the data analysis was conducted using SPSS26 and Smart PLS version 4. This study highlights the importance of digital platforms and ambidexterity mediators in the relationship between dynamic capabilities and organizational performance. It also addresses the lack of an effect of technological and market turbulence on the relationship between ambidextrous capabilities and performance. Finally, suggestions for future research are presented.

Athletes are more at risk of developing anxiety disorders, depression, and substance abuse disorders due to facing unique stresses such as balancing social life with sports and high public expectations. The cognitive-behavioral therapy model, in addition to helping athletic performance, can play a preventive role in the development of psychological disorders. This study aimed to determine the impact of the cognitive-behavioral therapy model (with an emphasis on the role of the technique of using others as a benchmark for belief modification) on depression and return to sports in an athlete with major depressive disorder. In this study, a 5-session cognitive-behavioral therapy intervention with an emphasis on the technique of using others as a benchmark for belief modification was conducted. The athlete's depression and anxiety were measured before the intervention, after the intervention, and at a 2-month follow-up stage. The results showed that the athlete progressed from severe depression and moderate anxiety in the pre-test stage to mild depression and anxiety in the follow-up stage, indicating the positive role of the cognitive-behavioral therapy model (with an emphasis on the technique of using others as a benchmark for belief modification) in reducing depression and anxiety in athletes. In the technique of using others as a benchmark for belief modification, the athlete looks at the adaptive beliefs of real successful individuals and distances themselves from their maladaptive beliefs. In other words, if athletes can realistically see and understand how to apply adaptive beliefs in other successful individuals who have been in similar or even much more difficult situations, they will take action to modify their maladapti
