Background: The research showed that having high scientific intelligence in students does not necessarily imply higher emotional intelligence or better motor efficiency, and these relationships may vary among individuals with different levels of intelligence.Aim: The present study was conducted to compare the motor efficiency and emotional intelligence of ordinary and gifted girls’ students aged 12-15 years.Materials and Methods: The present research was a causal-comparative study. This study was conducted on 100 participants two equal groups (50 gifted girls’ students from National Organization for Development of Exceptional Talant (NODET) and 50 ordinary girls’ students from ordinary schools) using random sampling method from 6 ordinary schools and 3 NODET schools in the first secondary level in Shiraz. The Trait Emotional Intelligence Questionnaire– Adolescent Short Form (TEIQue-ASF) and the Bruininks- Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) were used to measure emotional intelligence and motor efficiency, respectively.Results: The results showed that the motor performance of gifted students was significantly better than ordinary students (P=0.029). However, there was no significant difference in the emotional intelligence variable between the two groups (P<0.05).Conclusion: The research results indicated a significant difference in motor efficiency between gifted and ordinary students. This finding underscores the need for a more in-depth investigation into the potential causes of this disparity. Factors to consider include variations in the physical environment of schools, access to sports facilities, the role of physical activity and sports outside of school, and the differing social and economic backgrounds of families.

Background: Fatigue as one of the physiological factors can affect the physical performance of athletes. This issue is more important in young athletes and can expose them to injury. Aim: The purpose of this research was to investigate the effect of functional fatigue on the performance and landing mechanics of adolescence taekwondo athletes. Materials and Methods: This was a semi-experimental study. Participants were 20 male teenage taekwondo players. Pre-fatigue measurements included side-jump tests, figure-8 hop tests, and single-leg triple jump tests, as well as a lower limb biomechanics assessment using a landing error scoring system. After the functional fatigue protocol was applied, all the pre-fatigue variables were evaluated again. In order to examine the intra-group changes of the research variables in the pre and post-test stages, the paired t-test at a significance level of P≤0.05 was used. Results: The paired-t test results revealed that following fatigue induction, performance in the side-jump and figure-8 hop tests significantly deteriorated (P<0.05). Additionally, performance in the single-leg triple hop test declined (P<0.05). Moreover, landing error significantly increased (P<0.05). Conclusion: The finding of this study indicated that after applying fatigue, the subjects' performance decreased and the biomechanical error of the lower limbs increased. Fatigue can significantly impact adolescent taekwondo athletes' performance and biomechanics. So, taekwondo coaches should implement effective strategies to mitigate fatigue, enhance athletes' conditioning, and optimize their performance in training and competitions.

Background: Cardiovascular disease is a significant contributor to mortality in diabetic patients. Despite the potential benefits of concomitant and complementary training in diabetic patients, there is a paucity of evidence in this area.Aim: The objective of this study was to investigate the effect of aerobic training in conjunction with a hydroalcoholic extract of the fruit of Qaraqat on superoxide dismutase, glutathione peroxidase, total antioxidant capacity, and malondialdehyde in the heart tissue of male rats with type 2 diabetes.Materials and Methods: 24 male rats aged 8 weeks were diabetic with a high-fat diet (60%) and streptozotocin injection. They were randomly divided into four groups: (1) aerobic training (AT), (2) supplementation (Sup), (3) Aerobic training+ supplement (AT+Sup), and (4) diabetes control (Con). The training protocol included running on a treadmill at a speed of 5-24 m/min for 10-60 min, according to the principle of overload. Glucose, insulin, insulin resistance, and MDA, TAC, GPX, and SOD of heart tissue were measured. Statistical tests of two-way variance and post hoc Bonferroni were used using SPSS software at a significance level of P<0.005.Results A significant decrease in glucose levels, insulin resistance, and MDA (P<0.005) was observed in the intervention groups following eight weeks of training and supplement intervention, in comparison to the Con group. Also, the amount of insulin in Sup and AT+Sup groups exhibited a notable decline in comparison to Con and AT groups (P<0.005), as well as a substantial increase in the levels of SOD (P=0.001) and GPx (P<0.005), and TAC (P<0.005) was observed.Conclusion: Diabetes is associated with elevated MDA levels, which are reduced by aerobic training and supplementation. Furthermore, the administration of a training intervention and the utilization of a supplement have been demonstrated to elevate the levels of SOD, TAC, and GPx.

The purpose of this paper is to list and briefly discuss the top authors, organizations, universities, nations, publications, and journals in the topic of sports safety management. It also aims to provide the most linked patterns in terms of co-citation, co-authorship, keyword co-occurrence, temporal proximity, and substantial terms and concepts in the field of safety management based on content analysis. 214 pertinent international publications from journals around the world that were published between 1993 and 2023 were found in the Scopus citation database and comprised the statistical population for this study, which followed a systematic review process. In this study, software tools like Publish or Perish, Excel, Vosviewer, Rstudio, R and Maxqda 2020 were used to identify, quantify, and evaluate safety management elements in sports.The results showed that the United States has the most influence in this sector, with the University of Florida (USA) being the most significant university and organization. "Recreational Sports" is the most prominent journal in the field of safety and risk management. Konnaughton, D.P., and Spengler, Jo are the most significant authors in this discipline. Finally, a comprehensive and eight-dimensional model of safety management was created by merging the essential terms that were taken from the examination of the top 20 articles in this sector. In conclusion, it can be said that safety and risk management in sports can reduce sports-related dangers and boost safety standards, resulting in a significant advancement in athlete safety and a reduction in risks related to sports.
