The purpose of this study was to evaluate the psychometric properties of the Persian version of the Movement Imagery Questionnaire-3 (MIQ-3). At the first stage¡ MIQ-3 was translated into Persian according to the standard method. At the second stage¡ the factorial structure of the questionnaire was tested¡ using confirmatory factor analysis. A number of 164 male and 155 female athletes of different competitive levels participated at this stage; also the concurrent validity of MIQ-3 was evaluated¡ using Persian version of the Vividness of Movement Imagery Questionnaire VMIQ-2 (61 males and 43 females). At the third stage¡ the reliability of MIQ-3 was calculated by two methods¡ test-retest and internal consistency. In this stage¡ 53 male and 42 female athletes with a time interval of 14 to 30 day participated. The scale demonstrated good content and good factorial validity as well as good concurrent validity and internal consistency¡ it can be concluded that the Persian version of MIQ-3 has proper validity and reliability.

The purpose of this research was to study the relationship between sport orientation and aggression of martial arts athletes. The sample consisted of 167 athletes who were randomly selected. Results showed that there is a significant relationship between sport orientation and aggression among martial arts athletes. Also¡ the winning component there is a significant relationship with all aspects of sport aggression. Furthermore¡ the components of sport orientation were significant predictor variables in determining aggression. The findings revealed the importance of identifying the sport orientation in the level of aggression.

The purpose of this study was to examine the effect of cognitive¡ motivational¡ and combined (cognitive and motivational) imagery training on performance and learning of mini-basketball basic skills. 81 subjects were chosen based on their motor imagery questionnaire (Hall & Martin¡ 1997) scores and then randomly assigned to 4 groups (CIP¡ MIP¡ C-MIP and P). Results showed that the cognitive imagery group was superior in acquisition¡ post-test and retention. But the only significant interactions were found in both combined and motivational imagery groups in shooting and passing skills. The pattern of changing scores from pre-test to post-test was increasing for both groups¡ but this pattern from post-test to retention stage was increasing only for combined group. It seems that in the first stages of practice¡ using combined imagery containing cognitive and motivational components accompanied by physical practice¡ leads to better coding in basic skills such as basketball skills.

The purpose of this research was to investigate the effect of selected perceptual-motor training on memory and attentionproblems in children with intellectual disability. In this quasi-experimental study¡ 20 children¡ aged from 7 to 10 years old¡ were selected. They were divided into two groups of perceptual-motor practices and control according to age and IQ. Programs were held in 18 sessions (two sessions of 45 minutes in every week). Before the start of the first session and at the end of the last session¡ the neuropsychological Conner questionnaire was completed by their parents. Results showed that the experimental group in memory and attention performed better than the control group. Therefore¡ it is suggested that such movements must be included within physical education and extracurricular programs and at home.

The purpose of this study was to determine the locus of arousal and activation effects on information processing stages. A number of 30 non-athlete female undergraduate students participated voluntarily in this study. They performed Reaction Time Analysis (RTA) task using Vienna test system while their electro-dermal activity was recorded continuously during performance using UFI instrument. Task- related activation was calculated for each participant using the difference between skin conductance levels (SCL) during the rest with one''s during the task. Time used in each stage of information processing was also recorded. The results showed that activation was not correlated with duration of stimulus identification and response selection stages. Instead¡ and as a result of increase in activation¡ duration of response programming stage decreased. In conclusion¡ locus of activation effect was found on response programming stage.

The purpose of present research was to investigate the relationship between burnout with self-efficacy among super league selected sports coaches. The sample population included 135 coaches in group (basketball¡ volleyball and footstall) and 111 coaches in individual (Taekwondo¡ Wushu and Karate) sports. Results showed that there were significant and negative correlations between burnout with self-efficacy among group and individual sports coaches. Furthermore¡ multiple regression analysis results showed that there were inverse relationships between depersonalization and personal accomplishment components with self-efficacy could be anticipated the self-efficacy among group and individual sports coaches. Also¡ results showed that only there were significant differences among burnout and its components among group sports coaches¡ but there were not significant in these variables among individual sports coaches. Finally¡ the present research results showed that there were no significant differences between self-efficacy among individual sports coaches. Based on these results¡ could be stated that the high self-efficacy there was significant and powerful role in suffer of burnout and stress.

The purpose of the present study was to examine the effect of different attentional strategies on the accuracy of free throw as well as to examine the role of visual information in basketball novice throwers. Fourteen novice throwers from 21 to 28 years old were recruited. Participants performed 20 trials as counterbalance in various attentional conditions and in general performed 80 trials. In each attentional condition¡ half of the trials were performed using visual information and the other half of the trials were performed without the presence of visual information. The results of the factorial variance analysis with repeated measure indicated that the main effect of internal-external attention¡ the presence and non-presence of visual condition as well as the interactional effect of internal-external / relevant-irrelevant attention was significant. The other effects were not significant. In other words¡ the findings indicated that the external relevant attentional strategies in both visual and nonvisual conditions was better that the other strategies. Therefore¡ it can be suggested that it is better the coach’s use from external relevant attentional strategies.

The aim of this study was to compare sleep quality and psychological well-being in hospital staff with different levels of physical activity and circadian rhythms. This is an ex-post facto study. 180 female employees working in 4 main hospitals in Tehran were selected using Purposive sampling. Results of two-factor analysis of variance showed that there are Significant differences between sleep quality and psychological well-being of employees and level of low¡ moderate and high physical activity with fixed and rotating shifts and employees athlete with fixed shift were sleep quality and psychological well-being better than other employees. Also¡ employees with high physical activity level and fixed shift were better sleep quality than rotating shift employees with low and moderate levels of physical activity. Is recommended for health managers design intervention programs based on physical activity to for the prevention or reduction of sleep problems and psychological problems Staff.

The purpose of this research was determining the validity¡ reliability and normalization of the Persian version of Sport Anxiety scale-2 in athletic children. For this purpose¡ 400 boys and girls were chosen by random sampling. At first data was confirmed with use of translation- retranslation¡ face validity and translation accuracy methods. For scale construct validity¡ confirmatory factor analysis and for scale''s internal constancy and also infraclass correlations coefficient temporal stability¡ Cranach alpha coefficient was used. The results of research showed that Persian version of Sport Anxiety scale-2 in children has acceptable validity and reliability among athletic Iranian children and is able to be used as a valid and reliable instrument by trainers¡ and researchers.

The aim of this study was to compare the perceived motivational climate among male and female athletes in team sports.
