Introduction: To examine the effects of a 6-week hopping exercise program on time to stabilization and perceived stability among athletes with chronic ankle instability. This is a randomized controlled trial.Materials and Methods: A total of 28 basketball players with chronic ankle instability (Mean±SD age; 22.67±2.88 y, Mean±SD weight: 80.47±8.48 kg, Mean±SD height: 186.82±3.09 cm) participated in this study and were randomly divided into two equal groups of 14 people each: 1. Experimental; and 2. Control. The experimental group performed hop exercises 3 times per week for 6 weeks. The control group received no intervention. Time to stabilization for anterior-posterior and medial-lateral components of ground reaction force, as well as ankle joint function assessment tool were found before and immediately after the exercise program. Descriptive statistics, independent t-test, and paired sample t-test were used to analyze the data at the significance level of 95% (α≤0.05).Results: The 6-week hopping exercise program led to a significant decrease in the time to stabilization of medial-lateral and anterior-posterior of ground reaction force and also a significant increase in the score of ankle joint function assessment tool (p <0.05).Conclusion: Given the effectiveness of hopping exercises, postural control deficit, and time to stabilization in sport exercises, it is suggested that these selected exercises be used in training and rehabilitation protocols.

The present study aimed to investigate the relationship between perfectionism and narcissism with psychosocial adaptation in elite and non-elite athletes. A total of 200 elite and non-elite athletes (20-30 years old) who participated in the tournament of 2020 in Tabriz were randomly selected and completed the questionnaire of Sport Perfectionism - 2nd Dun et al. (2009 and 2010), Ruskin and Terry narcissism and Bell Social Adaptation Inventory. To analyze the results, Pearson correlation coefficient and simultaneous regression analysis were used. The results showed that in elite athletes group, there was a positive correlation between positive perfectionism (organizational and personal criteria) and psychological social adjustment, and between negative perfectionism (doubts about actions, perceived pressure of parents and perceived pressure of instructor) and narcissism with negative psychological social adjustment and both positive and negative perfectionism and narcissism variables could significantly predict social adjustment in elite athletes (P <0.05). In non-elite group between positive components of perfectionism, only the organizational component has a negative correlation with psychological social adjustment and the correlation between negative and narcissistic perfectionism components with positive social adjustment is positive. Among the components of perfectionism, the only negative components (too much importance by mistake, parental perception and perceived stress of the mentor) and the narcissistic variable have been able positively to predict psychosocial compatibility (P <0.05). Psychological social adjustment in athletes is one of the key variables in the professional and personal life of athletes, which is influenced by features such as perfectionism and narcissism.

Background: The coaching styles are a powerful force that can affect the health of athletes and their view of sports. Aim : The purpose of this study was to investigate the relationship between Coaches' Behavioral Style (CBS) and Exercise Pleasure (EP) and Athletes' Moral Health (AMH). Materials and Methods: This research is descriptive-correlational. The statistical population of this study included all athletes in Neyriz city. Three questionnaires were used for data collection: CBS questionnaire of Chelladurai and Saleh (1980), EP questionnaire of Scanlan et al. (1993), and AMH questionnaire of Vallerand et al. (1996). Descriptive statistics and the Spearman correlation coefficient were used for data analysis. Results: The results showed that although some of the components of AMH and CBS, such as negativism, were inverse, overall, there was a positive and significant relationship between CBS and AMH. Also, there was a positive and significant relationship between AMH and EP. Conclusion: According to the results, CBS can affect AMH and EP. Therefore, sports coaches should choose their behavior style according to athletes' needs, however, based on their willingness in supportive and participatory styles
