The aim of this study was to evaluate the effect of quiet eye training on selective attention, gaze behavior and free throwing of basketball under stressful conditions. The statistical population of the present study was all youth basketball players who participated in competitions in Tehran province. According to the type and purpose of the study, the sample was ranging in age from 16 to 22 years. A total of 24 people were selected and randomly and equally divided into two groups of 12 people (quiet eye and control training group). The study included a pre-test, post-test, first retention, pressure test and second retention. In the pre-test phase, participants performed 10 free basketball throws and at the same time their gaze behavior and performance were recorded. The training phase consisted of 3 sessions based on Vickers quiet eye training. The first post-test and retention stages were similar to the pre-test with a difference of 24 hours from each other and the pressure test was performed 48 hours after the first retention and the second retention phase was performed 48 hours after the pressure test. To analyze the data, combined analysis of variance test and Benferoni follow-up test were used and independent t-test was used to compare the groups. The results showed that quiet eye training had a significant effect on selective attention, gaze behavior and free throw performance under stressful conditions

Introduction: The purpose of this research was to study the effect of timing of using strategic self-talk on performance and novices. Methods: 36 new students in basketball skills were selected and randomly divided into three groups: strategic self-talk before providing feedback, after providing feedback, and control. In each session, 60 effort exercises were given from four points of the basketball arc. After every three attempts, the coach gave a feedback to the trainees about how to perform the skill. In the first experimental group, novices were taught to use strategic self-talk after completing three practice attempts and before providing feedback to identify errors; In the second experimental group, the novices were asked to use strategic self-talk after providing feedback to correct errors, and in the control group, exercises and feedback were given, but no self-talk was provided. Finally, two weeks after the end of the intervention, a recall test was held. Results: The results of the two-factor variance analysis in the acquisition phase showed that self-talk both before and after feedback led to improved performance and learning, but no significant difference was observed between the performance of the two self-talk measures in the acquisition phase, but in the memorization phase The strategic self-talk group before giving feedback was better than the self-talk group after giving feedback. Conclusion: it seems that strategic self-talk before re-presentation is beneficial for learning to shoot basketball due to attention to error identification and the use of coach feedback on how to correct errors.

The purpose of this study was to determine the effect of skill level on the performance of dribbling skills in soccer choking under pressure conditions. For this purpose, 20 skilled players of the university football team and twenty beginner students in football (with age range 18-25) participated in the study. The Egilly soccer dribble skill test was performed in two stages: without pressure condition and combined pressure condition. In the present study, the combination of two types of pressure, competition between participants and camcorders were used to create pressure condition. In order to ensure that the pressure conditions were applied, the level of competitive anxiety was measured using the second version of the competitive state anxiety and the heart rate of the participants. To analyze the data, repeated measures analysis of variance was used for comparing the mean scores and independent t-test was used to compare the mean scores of two groups without pressure condition. The results showed that the performance of the skilled group, decrease under pressure conditions and the performance of the beginner group improved under pressure conditions. It is possible that the pressure conditions in the beginner group would increase the effort to perform better and thus improve performance. It can also be said that the motivational role of pressure conditions has improved performance in beginners. In skilled persons, they are also likely to engage in skill-centered mechanisms that give less skill to the source of attention which is empirically evident in verifying the explicit review theory.

Theoretically, skill presentation will change behavior through processes such as imitation and motor repetition. If we want learning to happen, we need a process called training. Training can be delivered by the instructor through verbal and non–verbal instructions to the learner. One type of non–verbal instruction is pattern representation in which learner can learn through observation. The purpose of this model is to use the pattern representation as a means of transmitting information. Thus, the aim of this study was to evaluate the effect of three training methods: immediate, interspersed and combined imitation on Juno kata form performance. Therefore, 45 girls (9-12 years old) in Tehran city voluntarily participated in this study and were divided into three groups (each group 15 subjects) based on the type of intervention. Groups of immediate, interspersed and combined imitation had special imitation training programs with specific repetitions. In order to quantify data, 10-point Kata scale was used. As the data distribution and variance homogeneity were obtained, the result of analysis of variance with repeated measures showed that all three observational methods helped to improve the performance and this progress remained stable in the retention and transfer tests (P≤0.05). Also, the results of multivariate analysis of variance showed the priority of immediate imitation group on interspersed (P=0.0005) and combined (P=0.0005) imitation groups. The combined imitation group gained better scores than interspersed group (P=0.0005) and this differences was stable in retention and transfer tests.

Relaxation is a way of improving performance that can generally be classified as physical and mental relaxation. The mental relaxation technique is often named as the technique of mind to the body since the purpose of these techniques is to provide relaxation through the mind. The aim of the present study was to determine the effect a period of relaxation program (body to mind and mind to body) on the performance of semi-skilled football players. For this purpose, 39 players were selected and divided randomly into three groups: progressive muscle relaxation, creative visualization, and control. Before the interventions, a pretest was conducted by the observational method. In this relaxation program, subjects underwent two different types of relaxation after football training for 8 weeks. Data were analyzed using descriptive and inferential statistics, analysis of variance with repeated measures and one-way analysis of variance. The results showed the significant effect of progressive muscle relaxation and creative visualization on maintaining and controlling the ball, accurately passing, accurately taking the ball from the opponent and overall players’ performance. In addition, the athletes who used progressive muscle relaxation had better performance than those who used creative visualization. In general, the methods of the body to mind and mind to body relaxation can each serve as an independent way to improve the performance of athletes, but the implementation of mind to body relaxation, such as the visualization of creativity, is more effective at skills that require more precision and concentration.

Aim: This study aimed to determine effect of self-control of task difficulty on accurate and movement pattern golf putting. Methodology: Thirty novice undergraduate students (14 Female and 16 male; average age 21.1 ± 1.64 years) were quasi-randomly assigned to two groups. Before performing each trial during the acquisition phase, the self-control group was told they could choose any of the pre-set distances from the target: (25, 50, 75, 100, 125, 150, 175 and, 200 cm). Each self-control participant’s practice schedule was served as the predetermined practice schedule for each corresponding yoked participant. Participants practiced eight blocks of 10 trials. To analyze the radial error (in acquisition and tests phases) and the movement pattern score (in tests) mixed variance analysis with repeated measures on the last factor was used. The movement pattern score in acquisition phase was analyzed using t test. Results: Based on the results, radial errors across different groups in the acquisition phase did not vary, but the radial error of the self-control group in retention, single task transfer and dual-task transfer tests was lower compared to the yoked group (ps < 0.001). In acquisition and test phases, the golf putting movement pattern was better than that of yoked group (ps < 0.001). Conclusion: The efficacy of self-control of task difficulty is explained with reference to the challenge point framework.
