The aim of this research was to determine the impact of a psychological skills training (PST) course on the level of sports injury anxiety and fear of failure. This research was of an applied and cross-sectional nature, and the statistical population consisted of elite football athletes, among whom 45 completed the existing scale. The measurement tools used were the Sports Injury Anxiety Scale (SIAS) and the Performance Failure Appraisal Inventory (PFAI) to assess fear of failure. The pre-test for sports injury anxiety and fear of failure was conducted in all three groups, and the experimental group followed the corresponding protocol for 12 sessions, after which the post-test was carried out. The data were analyzed using the dependent t-test and ANCOVA. The results showed that after the intervention, sports injury anxiety and fear of failure had decreased, and there were differences in the responses to the items on the sports injury anxiety and fear of failure test between the two experimental groups, the pre-exercise intervention and the pre-sleep intervention. In general, it can be concluded that practicing psychological skills can be a strategy for reducing psychological responses such as sports injury anxiety and fear of failure. Sports psychologists are advised to use this intervention to reduce sports injury anxiety and fear of failure, and consequently to improve performance.

During the Covid-19 pandemic, the use of online sports programs became popular. The purpose of this study was to investigate the effect of eight weeks of online body balance program on anxiety, depression, and aggression of children with attention deficit/hyperactivity disorder (ADHD). Body balance is a sport based on yoga, tai chi, and Pilates. The present study was a semi-experimental and applied type of study. The participants of the present study were 30 volunteer children with ADHD who were divided into two experimental (15 people) and control (15 people) groups by random assignment method. Aggression, depression, and anxiety variables were evaluated by Bass and Perry questionnaire, Maria Kvas children's depression questionnaire, and Revised Children's Manifest Anxiety Scale. The experimental group performed online body balance training for 8 weeks (3 sessions per week for 60 minutes) online, and the control group did their current activities. In order to investigate intra-group and inter-group differences, repeated measures ANOVA at the error level of 0.05 was used by SPSS software. The results showed there was significant difference in the average level of symptoms of depression, anxiety and aggression in the pre-test and post-test stages (P≤0.05), between the two control and experimental groups (P≤0.05) and the interaction effect of time and group (P≤0.05). The results of Tukey's test showed that there was a significant reduction of these symptoms between the two experimental and control groups in the variables of depression symptoms (-5.500), anxiety symptoms (-5.133) and aggression symptoms (-13.133). Based on the results of this research, eight weeks of body balance training reduced depression, aggression and anxiety symptoms in 7-9 year old children with attention deficit/hyperactivity disorder. Therefore, the improvement of mental disorders caused by this disease in children following the body balance exercise program emphasizes the importance of using this intervention method for children with ADHD.
