Introduction: Wrestling is one of the most popular Olympic sports in Iran. Therefore, preseason screening and the prevention of sports injuries are very important. This study aimed to investigate the relationship between the history of injury and Functional Movement Screen (FMS) scores of the national team wrestlers and determine the cut-off point. Methods: The statistical sample included 136 national team wrestlers. The obtained data were analyzed using the Pearson correlation coefficient, t-test, ROC curve, and contingency table. Results: The results showed that FMS scores were higher in the wrestlers without previous injury compared to the injured ones. The t-test results demonstrated no significant difference between deep squat, straight and active leg raise, trunk stability push-up, and rotatory stability. According to the results, there is a poor negative, but statistically significant, the relationship between the number of previous injuries and FMS scores. Based on the ROC curve for FMS, the cut-off point of 16.5 was reported with the sensitivity and specificity values of 0.587 and 0.658, respectively. Conclusion: The results indicated that FMS can be used for fast and accurate control of injury probability in wrestling athletes. Therefore, besides the medical tests, FMS tests should be employed by wrestling coaches as a valid tool for injury prevention and the identification of athletes prone to injury.

Introduction: This study aimed to investigate the effect of a 4-week core stability training program on landing kinetic parameters in athletes with functional ankle instability during a single-leg drop landing exercise. Methods: This study used a pre-post quasi-experimental design and was conducted in the biomechanics laboratory. A total number of 24 athletes with functional ankle instability participated in two experimental (n=12) and control (n=12) groups. The experimental group performed core stability training for 4 weeks. The kinetic variables (maximum vertical Ground-Reaction Force [GRF], maximum shear GRF, and time to peak vertical GRF) were measured with force plate at the frequency of 400 Hz, in the pre-test and post-test. The obtained data were compared using Analysis of Covariance (ANCOVA) and multivariate analysis of covariance MANCOVA in SPSS V. 18. Results: In the experimental group, all variables significantly differ between the pre-test and post-test. Also, the ANCOVA and MANCOVA indicated significant differences between the experimental and control groups in all variables. Conclusion: The results indicated that the core stability training improved the kinetic parameters of landing in people with functional ankle instability; thus, it can reduce the re-injury risk of the ankle.

Little research has been carried out on the common symptoms and mental disorders in Iranian elite athletes. The purpose of this study was to identify the mental health problems in Iranian elite athletes as a retrospective study at the National Olympic Academy (NOA) of Iran. The present study is a cross-sectional and retrospective descriptive study which was conducted by evaluating the athletes' psychological documents. A total of 143 athletes (male, n= 83, female, n= 60) were analyzed from the population of elite athletes (n=240) who referred to the mental training and consulting center in the NOA during the years 2007-2021. The results showed that most athletes referred to the center to improve their performance (37.8%). Anxiety (27.3%), depression (16.8%), interpersonal problems (11.2%), impulsiveness (2.8%) post-traumatic stress (PTSD) (2.8%), sleep disturbance (1.4%) were the most common mental disorders reported by athletes. In addition, surveying the relationship between demographic characteristics and mental health issues revealed a relationship between gender and mental health problems; there was no relationship between other demographic variables with mental health problems. The results of this study illuminate the spread of common mental health problems in Iranian elite athletes over the last fourteen years. Screening and diagnosing psychological problems provide a better understanding of the application of appropriate psychological interventions and improving the mental health of elite athletes. Accordingly, future research may focus on better understanding of mental health problems reported in this study and studies them in a larger population.
