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.

This study aimed to investigate the resilience of sports clubs as business enterprises in the crisis caused by the Coronavirus epidemic. Thirty-five experts in the field of sports club management were interviewed in three rounds of interviewing. In the first round, the main questions for the interview was determined, and then two series of interviews were carried out with experts. Basis of the analysis in the second one was content analysis approache. A summary of the answers given to the sample and interviewing were conducted again. Kolmogorov-Smirnov and one-sample t-tests were used to measure the resilience. In the next study section, the propulsive forces identified with the Delphi technique and prioritized based on the degree of importance and uncertainty, and Micmac was used to write possible scenarios. Results indicated that resilience of sports clubs was not in a good condition in the presence of crises and challenges. The findings showed that poor management of sports clubs and low income were the most influential critical factors in resilience. A low partnership index with a total of 201619 had the highest impact. Organizations that responded quickly and actively and were user-friendly under adverse economic conditions were more likely to succeed.

Background: Late diagnosis and treatment of congenital hip dysplasia (CHD) can cause many problems in a person's daily life.   Aim: Therefore, the present study aimed to investigate and compare the effect of therapeutic exercises and education on parents’ weight bearing, range of motion, joint stability, and disease complications in 4-10-year-old children with congenital hip dysplasia. Materials and Methods: This semi-experimental study was conducted with a pre-test and post-test design on 40 children with CHD in two groups of 20 people: therapeutic exercises and education. The training program of the therapeutic exercises group was done on a middle day for 8 weeks from 60 to 90 min in each session. Also in the training group, parents were taught about the correct methods of sitting, standing, and lying down. Before and after the intervention, the subjects were evaluated by the researcher in terms of performance indicators. These indicators were evaluated with specialized tests (weight bearing with standing flexion test, range of motion with stork test, and joint stability with sitting test). The analysis of variance was used to compare the differences between groups in terms of the effect on the indicators. Results: Based on the findings, the difference between the two groups of therapeutic exercises and education to parents was significant in weight-bearing and range of motion (P=0.000 and P=0.000), but in hip joint stability and disease complications, no significant difference was observed (P=0.269 and P=0.163). Conclusion: Considering the greater effectiveness of the therapeutic exercises, it is suggested to design a codified program in the physical education program of U10 children to correct skeletal abnormalities, especially hip dysplasia.

In the contemporary global landscape, nations strive to portray themselves as modern and open societies, employing various tools, such as art diplomacy, scientific diplomacy, and sports diplomacy, as a compelling facet of public engagement, especially over the past two decades. This study aims to scrutinize the role of sports in interactions of Iran and Shanghai Cooperation Organization. The research was descriptive based on qualitative technic that was done by two round Delphi interviews. The participants consisted of 14 experts of sport policy and international relations and the data collection involved an examination of diverse sources, including articles, books, and websites of Google Scholar, Taylor Francis, and Sciences Direct. The qualitative section indicated three concepts of sport diplomatic interactions of Iran and SCO countries included: Economic, Political and Cultural factors. The findings also highlight Russia and China as promising prospects for fostering sports diplomatic interactions with Iran. Sports events that secure medals, notably gymnastics and swimming, benefit significantly from enhanced bilateral and multilateral exchanges within the sports competitions framework among Shanghai Cooperation Agreement nations.

Background: Identifying the practice conditions that optimize the learning of motor skills is one of the main objectives in the area of human motor learning research. Aim: The present study aims to explore the effect of success criteria in high-error practice conditions on motor learning, self-efficacy, and mood states among female students. Materials and Methods: This practical quasi-experimental study was conducted in a field setting. The participants were 30 female students from Yazd University, selected through convenience sampling. Completing the consent form, the selected participants were randomly divided into three groups: high-error practice with a large target (n= 10), high-error practice with a small target (n= 10), and a high-error control group (n= 10). Then, mixed ANOVA was applied in order to test the hypotheses. Results: The results revealed that both of the large and small target groups significantly outperformed the control group regarding the difference in performance accuracy. Moreover, considering mood states, in the small target group, significant differences were observed in the calmness, happiness, and total mood state subscales, while in the large target group, significant differences were found in the vigor, happiness, depression, and total mood state subscales. In terms of self-efficacy, significant differences were observed in the level and power dimensions in small target group; however, the power dimension was the mere aspect revealing significant difference in the large target group. Conclusion: The use of success criteria in high-error practice methods is beneficial, and it is recommended to adopt this approach to improve accuracy and stability in the practice sessions.
