Religion, as a set of beliefs, dos and don'ts, as well as specific and generalized values, is considered one of the most effective psychological supports that is able to provide the meaning of life in every moment of life and in special circumstances with explanatory supports will save a person from suspense and meaninglessness. The present research is of a comparative causal type and its purpose is to investigate the effect of religious attitude and emotional intelligence on the aggression of professional wrestlers. Data related to religious attitude, emotional intelligence and the effect of these two on aggression were collected from 100 wrestlers using religious attitude questionnaires, Shott's emotional intelligence questionnaire and Nelson's anger questionnaire. The results of the research showed that religious attitude and emotional intelligence have an interactive effect on reducing the aggressiveness of professional wrestlers. Based on the subjects' statements, the results showed that aggression among people with high religious attitude was lower than among people with low and medium religious attitude. The results of two-variable variance analysis also showed that the interactive effect of the two components of religious attitude and emotional intelligence on aggression is statistically significant, in other words, religious attitude and emotional intelligence have an interactive effect on the aggression component of professional wrestlers.

Purpose: Osteoporosis usually starts at a young age and progresses slowly over time. Therefore timely diagnosis of this disease plays an effective role in raising the level of health and public health in the society. The aim of this study was to investigate the relationship between some indicators of osteoporosis and bone mineral density of the pelvis in active elderly men. Methods: This study was semi-experimental. 25 active elderly men with the age range of 60 to 85 years were selected as available and with medical records. Anthropometric characteristics and serum indices of subjects were used as effective indices of osteoporosis. Pearson's correlation coefficient was used to find the relationship between bone mineral density of the pelvis and effector indices, data analysis was done using SPSS version 26 software. Results: The results of this research showed that in the active elderly men, there is a significant relationship between age (P=0.044), body mass index (BMI) (P=0.021), serum calcium (P=0.037) and phosphorus levels (P=0.046) and alkaline phosphatase (P=0.016), with bone mineral density (BMD) of the pelvis. No significant relationship was found between vitamin D with BMD of the pelvis (P=0.055). Conclusion: In general, the results show that there is a significant relationship between bone density and body mass index, calcium and serum alkaline phosphatase indices in active elderly men. Therefore, it is possible to use the serum levels of these indicators in predicting this disease, and exercise may also be one of the influencing factors, so the effect of exercise on other bone density indicators can be investigated.

Background: Taekwondo is a traditional Iranian martial art currently practiced in over 206 countries around the world. Aim: The present study aims to provide fundamental information on injuries in Iranian elite Taekwondo athletes. Materials and Methods: A total of 200 Iran Taekwondo national team athletes (means±standard deviations: Age: 28.8±10.7 years, Height: 175.7±9.2 cm, Weight: 69±14.7 kg) participated in this retrospective study. The data was collected based on the injury surveillance system during 2021. The questionnaire included personal information and Taekwondo-related injuries information. Data was illustrated using descriptive methods and was analyzed using the Chi-Square test ( P <0.05). Results: The overall injury occurred during training was more than competition ( P <0.05). The occurrence of acute injury was higher than chronic ( P <0.05), and the most prevalent types of injuries were strain, rupture, and muscle spasm. The number of injuries that occurred in the lower extremity was higher than in other parts ( P <0.05), and the knee was the most vulnerable joint ( P <0.05). The most important cause of injuries was fatigue ( P <0.05). The non-contact injury was the most significant injury mechanism ( P <0.05). The severity of injury in Iranian elite Taekwondo athletes was high ( P <0.05). Conclusion: It can be concluded that injuries during training were more than competition, acute injury was more than chronic, strain was the most common type of injury, and the most vulnerable joint was the knee. Fatigue was the leading cause of injuries in elite Taekwondo athletes. So, in designing an injury prevention program, these factors should be considered.
