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.

Background: Pregnancy can be a special but potentially stressful time for women. The routine life of female athletes who become pregnant may be challenged, and professional athletes may be more likely to experience psychological disorders during this time.Aim: The objective of this study was to compare the stress, anxiety, and depression levels in professional and novice pregnant athletes.Materials and Methods: 106 female volleyball players (42 professional and 64 novices) were selected as the research sample, based on their competitive levels and study participation criteria. Data were collected using a personal information form and the DASS-21 questionnaire developed by Lovibond 1995.Results: The results of the MANOVA test showed that pregnant professional athletes had significantly higher levels of stress and depression compared to pregnant novice athletes (P≤0.05). Although professional athletes had higher levels of anxiety than novice female athletes, there was no statistically significant difference between the two groups on this scale (P≤ 0.05).Conclusion: It seems that female athletes at high competitive levels experience increased psychological challenges because of the added responsibilities of motherhood, in addition to their sports commitments. It is recommended to prioritize physical and psychological interventions and strategies to enhance the mental well-being of these individuals.

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.

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.

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.

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.
