Generally, the music performances on sports activities are manifested and realized through the four mechanisms of reducing the feeling of tiredness, increasing excitement levels, creating harmony, and finally increasing calmness and the sense of comfort. This function becomes very important when considering that the music impact acts as a miracle doping in professional sports. Besides, the lack of enjoyment in sports activities is often mentioned as an obstacle to participation in sports activities. This article discussed, evaluated, and analyzed the research records in three main topics: 1. The benefits of music in sports activities, 2. The conceptual model for showing the different music impact in sports activities, and 3. The underlying mechanisms of music impact on sports. A scoping review of literature in sport and music field was conducted to fulfill the research objectives. Finally, the inference was made by proposing theories such as corresponding and induction of microscopic and macroscopic order along with another direct and secondary music impact. Researches have not been able to uncover all aspects of music magic secrets yet. So, this challenge remains for researchers and athletes on how to maximize the benefits of using music during sport and exercise by focusing on practical applied approaches.

Background: China is the undisputed power of sports in the world today and due to the close relations of China and Iran in many different aspects, the bilateral scientific works can be considered as well. Aim : The purpose of this study was to analyze the opportunities for the development of championship sports with a look at the cooperation document between Iran and China. Materials and Methods: The present study was a qualitative (descriptive-analytical) type of library studies in terms of applied purpose and in terms of data collection, which examined scientific works including books, articles, and notes during 2010-2021 about Iranian sports and China took place. Results: The research findings showed that the Islamic Republic of Iran and China, as two superpowers of West and East Asia, can have different sports interactions with each other in team and individual disciplines, respectively.

Background: There are relationships between exercise effect on mental health, especially negative emotions such as anxiety and stress. Aim : The aim study was the effect of participation in public sports activities based on the theory of planned behavior on the public health. Methods: This study is a descriptive correlation study with confirmatory factor analysis approach. Data was collected from 288 public sports participants of Tehran Municipality. Three standard questionnaires, including Goldberg General Health (1979) with 28 questions were used for collecting data. Results: Construct Variance extracted was 0.4, composite reliability 0.9 and Cronbach’s Coefficient Alpha 0.7. As a result, the convergence validity and reliability of the model were acceptable. Divergent validity, convergent validity and discriminant validity of the model were confirmed by first order and second order confirmatory factor analyses. The positive validity of all subscriptions for latent variables indicated the appropriate quality of the measurement model. In this model, it was found that regular physical activity combined with planned behavior had a direct effect of 53% (correlation 0.729) on general health. Conclusion: According to the structural equation model, it was found that regular physical activity combined with planned behavior has a direct effect of 58% on general health.

Background : People who use Outdoor fitness equipment in parks and gardens do not know how to use these machines and their use may cause them various types of injuries. Aim: Outdoor fitness equipment in parks from the perspective of sports injuries cognition was evaluated for people with hyperlordosis, chronic low back pain, and healthy individuals in two groups with and without a coach and training. Materials and Methods: In this quasi-experimental study, 30 middle-aged women with a mean and standard age deviation (48.96 ± 8.21 years) volunteered to participate in the study and were purposefully divided into two experimental groups (15 people). Controls (n = 15) were divided. There were 10 patients in each group with hyperlordosis and chronic low back pain and 5 healthy people. Pain intensity and lumbar lordosis angle were determined by VAS questionnaire and using a flexible ruler, respectively. The present study was performed for 60 minutes 3 days a week for 12 weeks. Results : After 12 weeks of training with training, a significant decrease in pain level ( P = 0.639, t= 0.481) was observed in the experimental group compared to the control group, but there was a significant difference in lumbar lordosis ( P = -1.246), t= 0.235) users were not observed. Discussion and Conclusion : The results of this study showed that working with Park Sports Equipment with the presence of a coach and proper training reduces back pain in users with chronic low back pain and develops the general health of users of these devices.

The present study aimed to investigate the relationship between perfectionism and narcissism with psychosocial adaptation in elite and non-elite athletes. A total of 200 elite and non-elite athletes (20-30 years old) who participated in the tournament of 2020 in Tabriz were randomly selected and completed the questionnaire of Sport Perfectionism - 2nd Dun et al. (2009 and 2010), Ruskin and Terry narcissism and Bell Social Adaptation Inventory. To analyze the results, Pearson correlation coefficient and simultaneous regression analysis were used. The results showed that in elite athletes group, there was a positive correlation between positive perfectionism (organizational and personal criteria) and psychological social adjustment, and between negative perfectionism (doubts about actions, perceived pressure of parents and perceived pressure of instructor) and narcissism with negative psychological social adjustment and both positive and negative perfectionism and narcissism variables could significantly predict social adjustment in elite athletes (P <0.05). In non-elite group between positive components of perfectionism, only the organizational component has a negative correlation with psychological social adjustment and the correlation between negative and narcissistic perfectionism components with positive social adjustment is positive. Among the components of perfectionism, the only negative components (too much importance by mistake, parental perception and perceived stress of the mentor) and the narcissistic variable have been able positively to predict psychosocial compatibility (P <0.05). Psychological social adjustment in athletes is one of the key variables in the professional and personal life of athletes, which is influenced by features such as perfectionism and narcissism.
