Introduction: This research was conducted to determine whether professional athletes with Chronic Ankle Instability (CAI) exhibit differences in maintaining balance under conditions of with and without visual informationMaterials and Methods: Forty-five elite players with CAI were classified into soccer, volleyball, and basketball groups (n=15 each). All participants performed a static single-leg balance test in conditions wherein visual information was provided and withheld. Also, their center of pressure (CoP) oscillation parameters was measured. The data were examined through an analysis of variance (ANOVA) and the Tukey test.Results: A significant difference was found between the soccer and volleyball players (P=0.034) in anteroposterior CoP displacement. Furthermore, there was a significant difference between soccer compared with volleyball (P=0.001) and basketball (P=0.02) groups regarding mediolateral sway and sway area (P=0.003 and P=0.03, respectively) when they performed the test with their eyes open. A significant difference occurred between the soccer and volleyball players concerning anteroposterior and mediolateral sway (P=0.002 and P=0.04, respectively) and sway area (P=0.004) when they performed the test with their eyes closed.Conclusion: Given the necessity of maintaining a good balance in sports, volleyball coaches should design practices that reduce players’ reliance on visual information. These practices should strengthen their proprioceptive abilities through an increased challenge to their proprioceptive senses.

The purpose of this study was to identify and to prioritize the most important criteria to choose qualified coaches for the basketball national teams in Iran based on the perspective of sport experts, managers, basketball coaches, and elite players. Method used in this research was descriptive and survey kind. 135 participants were studied through random sampling approach according to the Morgan table. After collecting the questionnaires, 110 samples were qualified for further investigations. The data was analyzed with both descriptive statistics and inferential statistics including Kolmogorov-Smirnov test, Friedman test for finding the priority of criteria and analysis of variance test, using SPSS software. The order of the eight identified treats include “Personality and Cognitive Features, Emotional and Humanistic Characteristics, Social Characteristics, Managerial Skills, Scientific Knowledge and Expertise, Coaching Experiences, Demographic and Personal Characteristics, and Basketball Sport Skills”. Personality and cognitive features of a coach with mean rank of 6.35 is the most important factor to choose a coach (X2= 61.39, p <0.01) among the eight main criteria. Significant differences were obvious only on the last two items including “Sport skills” and “Personal characteristics” among male and female subjects.

Several metabolic changes caused by regular exercise, can lead to adaptive mechanisms in athletes. These changes create a new dynamic balance that ensures better performance. On the other hand, because most studies on changes in the metabolic profile of the blood have been conducted in male athletes, this study investigated the effects of different exercise conditions on reactive oxygen species (ROS), adiponectin, and subjective mood in female athletes. A cohort of 30 females, 20 professional players (10 target shooters and 10 basketball players), and 10 sedentary females as control group were enrolled in the study. Capillary blood samples and the Brunel Mood Scale questionnaire (BRUMS) were collected at noon before the training session. ROS and adiponectin were determined by the ELISA method. To compare among groups, one-way analysis of variance and Tukey's post hoc test were used at the significance level of P<0.05. Physiological evaluations showed a significant high level of adiponectin in basketball players (p=0.005). The anger subscale in the basketball group had a significant increase compared to other groups (p=0.04). The tension subscale exhibited a higher level in the shooting group than in the control group. (p=0.017). Regarding the vigor subscale, there was no significant difference in experimental groups, and there was a significant difference in the non-athlete group (control) (p=0.001). Basketball, being a team sport, exhibits a greater degree of aggression in contrast to shooting, which is classified as an individual sport. More focus of coaches on adjusting in another sport with non-competitive and non-confrontational features to reduce anger is suggested.
