Abstract
This research aims at studying the effect of different Practice Schedules (Blocked, Random, and systematically increasing) on acquisition, retention and transfer different basketball pass Species (overhead, chest and single arm). Subjects included 45 secondary male students (Mean age 17.14± 0.75) whom were assigned into three matched groups Blocked, Random and systematically increasing (its mention increasing systematically contextual interference to in training duration) following pretest. The subjects didn’t have any experience in playing basketball. At the determined and given condition for each group, subjects performed the task for 9 sessions 9 trials in each session. After 24 hour, retention and transfer tests with 4 trials in each pass were taken. Results showed effect of practice session was significant but no significant difference in acquisition between groups. In retention and transfer tests, there were significant differences between mean scores of practice groups, that supported Magill and Hall theory (1990) and challenge point idea of Guadagnoli and Lee (2004).

Abstract
The purpose of current study was to consider a course of doing psychological skills training (PST) program on chosen mental skills and the performance of teenager female taekwondo athletes with mean age 16 years of Iranian national team in 2009. The current study is in tentative type and pre and post test design with control group. To do this 22 people (female) among invited people to the camp of taekwondo national team in teenager level for participation in Asian competition of Kish were randomized and then were separated into two groups of control (10) and experimental(12). Then both of them completed the OMSAT-3 questionnaires in pre-test stage, so that to be evaluated from the view of mental skills and making check list for performance evaluation. According to gained results of questionnaires in pre-test stage and based on subjects weakness in skills of reaction to stress, fear controlling and concentration, an exercise package of purposing, goal setting, relaxation and imagery was used as PST program. After 4 months PST program of both groups was performed. Collected data was considered by independent statistical t-test. The results of this study showed that there is a significant difference between control and experimental groups in skills of reaction to stress and concentration after doing a course of PST program (P < 0.05). But there was no significant difference between these two groups in skill of fear controlling (P > 0.05). At last the results showed that there is a significant difference between control and experimental groups in performance after doing a course of PST program (P < 0.05).

Abstract
The primary aim of the present article is to analyze the efficiency of religious orientation in predicting flow experience of physical education students based on demographic variables. Also, the role of demographic variables was taken into account as the secondary aim of the study. 200 physical education students of the University of Isfahan were chosen randomly. They answered Religious Orientation Scale (Alport & Ross, 1987) as well as Flow Experience (Csikszentmihalyi, 1982). Multiple Regression Analysis was used to analyze the data and the structural analysis software was used to check the efficiency of the model. The results indicated that the intrinsic religious orientation model was positive predictor of the flow experience while the extrinsic religious orientation model was negative predictor of the flow experience. Also, the role of demographic variables indicated that the relationship between age and education with flow experience is positive and significant. In addition, it was revealed that the religious orientation model with the presence of demographic variables has the necessary efficiency in order to predict flow experience. All in all, the results of the present study confirmed that the intrinsic religious orientation is efficient in predicting flow experience.

Abstract
In recent years, leadership studies have been expanded and new leadership models have been presented by scholars that one of these models is toxic leadership. Contrary to positivist leadership styles, toxic leadership emphasizes the negative aspects of a leader. The popularity of the dark leadership vision has led to the development of a toxic leadership model. The present study seeks to investigate the consequences of toxic leadership with an emphasis on mediation role of unit civility. This is a applied and descriptive study and has been performed by survey method. For this purpose, a sample of 210 sports athletes in Semnan were randomly selected. Data were collected with questionnaire and analyzed using structural equation modeling in Smart-Pls software. Findings show that, toxic leadership has a significant relationship with organizational cynicism and Intention to Leave. There was a negative and significant relationship between toxic leadership, organizational trust and unit civility. In addition, the unit civility has a negative and significant relationship with organizational cynicism and Intention to Leave. Also, there was a significant relationship between unit civility and organizational trust.

Abstract
The ability to direct the gaze to optimal areas in the environmental context, at the appropriate time, is central to success in all sports. The aim of this study was to changes determine the elements of QE, during the run a reactivity launcher targeting skill, under different environmental demands. That was done to identify perceptual - cognitive effects performance-based infrastructure processes. Thus, 8 Athletes (22-28 Years old) with at least 5 years’ experience in dart throwing, in a counterbalanced manner performed under four target conditions of constraints environmental. Regulatory conditions (stationary/in motion) and inter-trial variability (present/absent) created four target conditions for reaction. During the run a launcher targeting skill and was continuously recorded characteristics related to gaze behavior in each scenario. In each condition, 10 trails 20 seconds conducted. Gaze behavior using an eye-tracking device Dikablis Professional Wireless model recorded and analyzed using DLab software information processing system and variance (ANOVA) with repeated measures. Results showed that there was significant between averages QE in four different environmental contexts (P≤0.001). The fastest QE onset was observed stationary – no inter-trial variability and QE offset and QE period belonged to in motion – no inter-trial variability and in motion– inter-trial variability. In general investigating factors involved in skillful performance in different implementation conditions in response to various constraints can be facilitator and effective in identifying important factors learning motor skills.

Abstract
The purpose of this study was to examine the effect of motor dependent/independent visual perception training on visual-motor integration and fine motor skills of 7-8 year old children .For this purpose, 107, 1st grade primary school students in Sabzevar were selected through purposive sampling (with equal economical and cultural status , optimum mental and physical health and full sight with or without wearing glasses) and randomly divided into two experimental (no=32)and a control group (no=43). After attending a pre-test session, one of the experimental groups was trained in movement dependent visual-perception tasks while the other group performed movement independent visual-perception tasks. Both groups performed their tasks for three sessions, 45-minute per week and for six consecutive weeks. Shapiro-Wilk and Levin test results confirmed the normality and homogenity of data and ANCOVA showed that both training programs significantly improved visual-motor integration and fine motor skills of 7 to 8 years old children. However, Bonferroni test indicated that there were no significant differences between the movement dependent and independent training programs. The data analysis was performed by using SPSS 19.0. The results of this study confirmed the purposed "movement" hypothesis stating that the significant contributor to the development of perception and perceptual-motor components is not the active or passive movements of the individual, but rather it is the attention of the person to the visual stimuli within the environment.

Abstract
A few studies have examined the interactive self-control effect on the type of self-modeling feedback. The purpose of this study was to determine the effect of providing different strategies of self-control feedback through self-modeling on learning of Lay-up shot basketball skill. For this purpose, 60 right-handed 11-13 years old male beginner students were selected through available sampling. Then they were divided into 4 groups randomly. One of the groups between the blocks and the other group before training session defined to get the type of self-modeling feedback (best performance or overall performance in Lay-up shot basketball skill). For each of these groups, the yoked group was selected. The training program was conducted for 6 sessions for two weeks. Pretest, retention and transfer test were made in 12 attempts. Results showed significant effect between pretest with retention and transfer tests scores. Also, there was significant difference between the self-control feedback before sessions and the self-control feedback between the blocks groups and their yoked group in the retention and transfer tests (P≤001), While between the yoked groups did not had any significant difference. These results indicate the greater effect of self-control feedback during sessions, which emphasizes the greater autonomy of learners as one of the psychological needs for learning optimization.

Abstract
The aim of this study was to examine sport hero/ine’s features and barriers to achieve their status based on students’ viewpoints. 300 students participated and wrote about obstacles of achieving the status of their hero/in through answering open questions. Data were analyzed using descriptive-analytical method and using Van Dijk's theoretical model (2004) in the framework of critical discourse analysis considering macro and micro levels. In describing the sports hero/ine, the women pointed to physical, facial, and behavioral-moral traits, respectively. Also men pay more attention to behavioral-moral, faces and personalities than other traits. The frequency of describing physical, facial, and behavioral-moral traits was significantly higher than other traits. Barriers were divided into 6 classes. Based on the Proportion test, Economic, socio-cultural and personal barriers make the hero's position significantly more difficult than other barriers. Analysis according to macro level of Van Dijk square represented that emphasizing negative properties of Them has the highest frequency among other properties. Participants have used micro strategies of fallacies, victimization, generalization and lexicalization to express barriers. The variables governing the minds of participants and how they are applied in the language suggest that they create inappropriate conditions for making a pattern to be hero/ine.

Abstract
The purpose of the present study was to investigate Effect of self-regulation from biofeedback exercises on the learning of dart throwing skill under pressure conditions. Participants were 28 undergraduate male students of the University of Tehran who were selected in an accessible manner as they were right-handed and had no experience in dart throwing and working with biofeedback devices. These numbers were randomly divided into four groups of visual, auditory, combined and control biofeedback. The number of biofeedback training sessions was 4 sessions with pre-test, post-test and retention sessions in 4 weeks. The results of analysis of covariance and mixed analysis of variance with repeated measures showed that visual, auditory and combined biofeedback training had a significant effect on the learning of dart throwing skills under pressure (P <0/05). According to the research findings, it is suggested to use biofeedback of temperature and galvanic response of the skin, visually, audibly or in combination, to learn darts throwing skills and skills similar to and close to darts throwing skills, as well as feedback of biofeedback sessions. Prioritize the combination biofeedback to see the best results.

Abstract
The aim of this study was to investigate simultaneous changes in EMG pattern during learning dart skill in dominant and non-dominant hands. The samples consisted of 10 non-athlete students with an average age of 23±2.5, which were divided into two group dominant hand (5) and non-dominant hand (5). Repeated measures ANOVA were used to measure data at the execution level and changes in EMG activity. The results showed a significant decrease in the absolute error of dart throwing at the performance level and an increase in EMG activity at the muscle level along with a decrease in muscle co-contraction in the acquisition and retention stages in both groups (P<.05). Also, there was no significant difference between EMG activity in the dominant and non-dominant hand groups after skill acquisition (P>.05). Generally, the results of this study showed that along with relatively constant changes in performance during dart skill learning, relatively constant changes in EMG patterns also occur, so that the concept of motor learning is also observed at the muscle level. Also, the results of this study supported the existence of the same motor program for dominant and non-dominant hand control, even in the conditions of bilateral transfer control.
