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.
