This study compares externalizing behavior disorders in overweight and normal-weight boys. The statistical population includes all the male students of elementary schools in Mashhad, who were selected using the cluster sampling method, six districts, and among the schools in this district, two boys' schools and a total of 222 students were selected as the research sample. Children's Behavior Checklist (CBCL) was used as a tool in this study. The results showed that, in general, there is a significant difference in externalizing behavior disorders between overweight and normal-weight boys (P<0.05), which is seen in conduct disorder and oppositional defiant disorder. In comparison, these two groups had no significant difference in attention deficit hyperactivity disorder (P<0.05). According to the results of the research, informing and changing the attitude of parents in preventing the occurrence of obesity and overweight and ultimately behavioral problems seems necessary, and since the deviation from normal weight is related to inappropriate and risky behaviors, early interventions and appropriate planning in this field is practical and necessary during the sensitive period of childhood.

The purpose of this study was to research the subjective experiences of an athlete during practice match competitions and to examine the potential usefulness of an adapted MAC intervention in addressing the emotional difficulties of the athlete. We investigated the usefulness of a 12-session MAC program altered for educational purposes and presented data as a case study. The case study suggested that the athlete experienced a multitude of anxiety while practicing match competitions; the athlete typically avoided these emotional difficulties and engaged in avoidant behaviors; an adapted MAC approach for educational purposes could be helpful to help the athletes accept private events, commit to performance-related behaviors, and engage more frequently to performance under pressure. More could be done to address the needs of athletes experiencing performance anxiety beyond the structure of our 12-session educational intervention. We concluded that the MAC-based intervention, to a certain extent, educated the athlete about how to meet the challenges of performance difficulties, commit to values-driven behavior, and exhibit behaviors that would potentially permit optimal performance.

Shooters typically make great efforts to strengthen their physical and motor abilities, but are often less aware of the cognitive and psychological factors that affect their performance and skill performance. Therefore, it seems that shooters, especially novice shooters, are not very familiar with the mental skills related to shooting and pay less attention to mental training. However, cognitive training has recently been recognized as one of the basic skills required in perceptual-motor activities. The present study was conducted to determine the effect of training cognitive imaging strategies versus training of motor representation strategies on the acquisition and retention of shooting skills. This randomized controlled clinical trial study was performed on 45 undergraduate military science students with an age limit of 18 to 25 years, studying in the second semester of 1997-98. Subjects were randomly selected from a university of military sciences in Tehran and randomly divided into three groups of mental imagery, motor representation and control using a table of random numbers. The intervention groups received a three-week mental imagery training program, motor representation along with shooting training (five sessions per week). The control group only participated in shooting training. In order to evaluate the performance of shooters in the pre-test, post-test and memorization stages, a SCAT machine was used. Statistical analysis was performed using SPSS20 software and p value less than 0.05 was considered significant. The results of combined analysis of variance showed that both cognitive imaging and motor representation interventions had a significant effect on improving the record of novice military shooters (P≤0.05). The results showed that although there was no significant difference between motor representation and cognitive imaging groups in the post-test stage, however, a significant difference was observed between the motor representation and cognitive imaging groups (P = 0.006) in the retention stage. The results show that cognitive imagery and motor representation interventions can improve the performance of novice military shooters, although motor representation is more likely to be effective than cognitive imagery

Emotional abuse is one of the most common types of abuse in sports. However, due to the lack of awareness of its harmful effects and the hiding of this abuse in the shadow of success, less attention has been paid to it. Objective: Emotional abuse is a repetitive pattern of intentional and non-contact behaviors that is performed to control a person and is detrimental to their emotional, cognitive, or physical health. The purpose of the present study was to investigate the prevalence of emotional abuse among semi-professional adolescent male football players in Mazandaran province. Method: the present study is cross-sectional. A total of 59 football players (aged from 15 to 18 years old) participated in the study voluntarily. Semi-structured interviews were employed to collect data and descriptive statistics and Spearman correlation coefficient were utilized at a significance level of 0.05 to analyze them. Results: The results showed that 37.25% of the participants have experienced emotional abuse such as humiliation, insult, ignoring, ridicule, etc. by the coach during their sports career which resulted in outcomes such as depression, eating disorders, anxiety, and low self-esteem. Conclusion: Based on the findings, it can be concluded that significant ratios of athletes have experienced emotional abuse that has adverse consequences and, in some cases, has led to quitting sport. Therefore, teaching athletes appropriate coping techniques reduces the frequency of common emotional abuse and protects them from it harm in the future.

Present research is considered applied-developmental in its objective and qualitative concerning the research nature of data, and the research design was the interpretative structural model (ISM). In order to gather data, semi-structured in-depth interviews with experts in the consumer behavior domain, selected by theoretical sampling, have been utilized. The statistical population includes all sports managers, sports specialists, and fans, and sampling continued until theoretical sufficiency was achieved. After research completion, results were sent to two participants, and their opinions were approved by identifying indices related to football fans' superstitious behavior to draw the interpretative- structural model of factors influencing football fans' superstitious behavior. The result indicated the level of dependence and influence power of each index according to which individual characteristics and environmental conditions in the region under the influence include inculcation index in the autonomous region (independent) and indices of relief, the transmission of evil, coercion, and deterrence in the dependent region.
