Few studies have investigated dimensions of attention out of laboratory settings. The aim of this study was to investigate the interaction between internal/external and associative and dissociative attention and its role in expert judo players’ technical performance during competition. mixed method approach with parallel-design was used. In the qualitative section of the study, expert judo players’ attentional strategy was explored using self-confrontation interviews. In the quantitative part of the study, differences between reported foci in successful versus unsuccessful trials was tested.  Analysis of interview transcripts revealed that expert judo players had more focus on external-associative dimension in both preparation and execution phases. In addition, results of chi-square test indicated a significant difference between judo players’ focus of attention in successful versus unsuccessful trials (p < 0.05) with more focus on external-associative attention in successful trials. In conclusion, while this study does not support use or advantages of dissociative attention in skilled performers, provided more support for constrained-action hypothesis as indicated more use and advantages of adopting an external-associative focus for expert level judo players.

Obesity is associated with a variety of diseases and efforts to reduce its problems are important. The purpose of this study was to comparison the effects of local native games (game-based interventions) and selected motor-based interventions (skill-based interventions) on the fundamental movement skill of preschool-aged obese girls in Tehran. This study was a semi-experimental with a pretest-posttest design. Thirty obese girls were selected in a targeted way. They divided into control groups, selective motor and local native games interventions. World Health Organization charts were used to determine the rate of obesity and the TGMD-3 test was used to measure the fundamental motor skill. Experimental groups practiced two sessions in week and per session one hour for nine weeks. The control group performed their usual activities during this period. Data were analyzed using covariance analysis. The results showed that there was a significant difference between groups at post-test (p = 0.000); analysis of variance and LSD test were used to examine differences between groups. The results showed that there was a significant difference between skill-based and game-based intervention groups in the TGMD-3 test in displacement scores. Whereas skill-based intervention had more effect than game-based intervention (P = 0.04), but the effect of two training methods for ball skill on the TGMD-3 test was not significantly different (P = 0.71). Also, both training groups had more effect on the dependent variables than the control group (p <0.05). Based on the results of the present study, it seems that both interventions are effective in reducing motor problems in obese children as both groups performed better in posttest than control group. This confirms the role of physical activity in reducing obesity in obese people. However, it is better to use selected motor interventions in accordance with the results of this study for movement skills.

​Many studies have shown the effectiveness of verbal instructions and observational training on the improvement of children’s motor skills; however, there is not enough information about the simultaneous effects of these two variables. The aim of this study was to investigate the effect of attention instructions during observation of the model on gaze behavior and accuracy of overarm throwing in children. 24 children 7 to 10 years of age with normal growth selected purposefully and randomly divided into two internal and external attentions during modeling groups. Training in both groups included observation 10 times skilled model overarm throwing’s film with eye movement recording, with the difference that before it each group received its own instruction. The results of mix-ANOVA and paired and independent t-tests showed that both groups showed a significant increase from the pre-test to post-test in the accuracy (p=0.001; p=0.001) and duration of the quiet eye (p=0.005; p=0.001) of overarm throwing. In the post-test, the external attention during modeling group compared to the internal attention during modeling had significantly higher accuracy (p=0.01) and longer quiet eye duration (p=0.001). Also, the external attention during modeling had more percentage viewing time to relevant external cues (ball and trajectory). Therefore, directing visual attention to movement effect of observed pattern cause improvement in motor performance and visual-motor expertise in children.

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.

The aim of this study was to compare the effect of training type (full-error and error-less) and skill level on the development of mental representation of putt golf skill. For this purpose, 44 undergraduate physical education students (22 women, 22 men; mean age 22.34 and standard deviation 4.37) were randomly divided into two groups: error-less (near-to-far) and full-error (far-to-near). The two groups practiced in the one-day acquisition phase of 3 blocks of 10 attempts for throwing distances (25, 50, 75, 100, 125, 150 and 200 cm). The error-less group started training from the closest distance to the goal and reached the farthest distance, respectively, but the full-error group started training from the farthest distance and finally reached the closest distance. At the end, they were tested immediately. One day after the acquisition phase, delayed retention tests, single task transfer (from a distance of 225 cm) and dual task transfer (from a distance of 200 cm simultaneously with audio playback) were performed. To compare the effect of error-less and full-error training on the acquisition, retention and transfer of putt golf skills, data analysis of the acquisition stage was analyzed by repeated measures analysis of variance (2×8). SDA-M test was used to measure the structure of mental representations formed in the two groups before and after the acquisition period, and hierarchical cluster analysis  0.05) was used to analyze the mental representations.  Our Findings showed significant functional changes in the post-exercise mental representation structure, suggesting that motor skills are associated with functional adaptation of action-related knowledge in long-term memory.

In scientific marketing models, attention is the main step in the effectiveness of advertising. That's why, competition over attention to advertisement has been of prime importance for the sponsors and marketers. However, sport marketing research has not yet been able to gain a proper understanding of the factors that influence the viewer's attention to advertising while watching a sport event. Different methods of data collection and using different evaluation tools can also help managers and sponsors make the right decisions. This semi-experimental research has compared the methods of evaluating TV viewers' attention to advertising through sport. For this purpose, 60 targeted sampling in the form of two groups of women (n = 30) and men (n = 30) watched the football match between Esteghlal and Persepolis in a laboratory site. While samples were watching the football match, meantime designed advertisements were presented too, the viewer's eye information was stored by the eye tracker in the form of fixation and duration. In addition, at the end of the test, the participants' attention to advertising was evaluated using an attention questionnaire. Analysis of the findings showed that in evaluation of the viewer's attention to advertising by questionnaire; there is no difference between males and females. But in both of Eye Tracking variables, females paid more attention to advertising than males. Also, the correlation between the results of the questionnaire and the Eye Tracker was not significant. Finally, in order to achieve new results and to develop the advertising industry, as well as identifying the factors affecting the effectiveness of advertising, it is better to use neuromarketing tools as a complement to other methods of data collection (questionnaire, interview, observation).

Video feedback is a type of augmented feedback that includes showing an athlete or performing a skill with a video clip of oneself or another person performing a particular skill. The aim of the present study was to determine the effectiveness of dyad training with video feedback on learning crawl swimming. For this purpose, 24 male students ranging in age from 11 to 17 years, who had no previous experience in learning crawl swimming, formed two groups of 12 people in dual practice and dyad training with video feedback. Both groups were first justified by the instructor, then in the double exercise group, one of the trainees entered the water and the other watched him perform out of the water, and after trying, they reviewed the mistakes and movements with their friend. in the dyad rehearsal group, one of the friends filmed another performance and showed it to him. The training intervention lasted for 8 sessions and 10 training attempts in each session. After the end of the eighth session, the 10-meter breast crawl swimming acquisition test was performed, and then a reminder test was performed again one week later and filmed. The results showed that the two groups had significant differences in both acquisition and retention, and the dyad training group with video feedback performed better overall. Based on the results, it can be concluded that the dyad training with video feedback method, in addition to being cost-effective in terms of energy consumption and training space, is also more effective than dyad training in swimming training.

The purpose of this study was to investigate the effect of practice variability in physical compared with observational practice on golf putting performance. To this end, 50 male right-handed students (25±3.7 years) of the Ferdowsi University of Mashhad participated in this study. Participants were randomly divided into 5 groups (physical constant, physical variable, observational constant, observational variable, and control). During acquisition, the physical variable group randomly performed 50 trials from 5 different starting points to 2 different targets, but the physical constant group performed 50 trials from one starting point to one predetermined target. The observational variable and constant groups observed the performance of the physical variable and constant groups, respectively. The control group just participated in pre-and post-tests and did not practice any trial. Participants performed a test just like the pre-test 10 minutes and also 24 hours after practice. Putting accuracy was measured as the dependent measure. Results showed that variability of practice had a positive effect on participants’ performance than constant practice in physical and observational conditions (all P<0.05). Maybe the similar underlying mechanisms and also the similar feedback effects resulted in the higher performance of the variable group than the constant group in physical performance and action observation.

Coaching is a dynamic and multidimensional process that involves the interaction between the coach, the athlete, the environment and the task, in order to enhance the athlete's performance. Based on the evidence, the coaching method can affect the behavioral aspects of the athlete. In this study, the effectiveness of student-based and coach-based coaching styles on sport self-efficacy and athletic performance of female gymnasts was studied. The research method was quasi-experimental and a pre-test-post-test design was used. The statistical population was female semi-professional gymnasts aged 11-14 in Tehran. The sampling method is one-stage cluster and the research sample was 40 female gymnasts. Variable assessment tools included Sport Self-Efficacy Questionnaire and a researcher-made sports performance Checklist. After the pre-test, the groups performed the athlete- based and coach- based exercises protocol separately for two months and two days a week in one-and-a-half-hour sessions. Covariance analysis was used to test the hypothese. Findings in the post-test stage showed that sport self-efficacy (P <0.001) and athletic performance (P <0.001) of female gymnasts in the student-based group were significantly higher than the coach-based group. It is concluded that student-based exercises style is more effective in increasing Gymnasts' sports self-efficacy and athletic performance compared to coach-based, and coaches are suggested to pay special attention to student-centered exercises in the training program for semi-professional gymnasts.

The effect of relative and chronological ages on the motor abilities of 7 to 12 year old students
Abstract
The aim of this study was to investigate the effect of relative and chronological age on the motor abilities of students aged 7-12 years. 600 male and female students were selected in three age categories: 7-8 years, 9-10 years, and 11-12 years. To determine the relative age, the date of birth was collected. Then, the months of their birth were determined and it was converted into months and years. The motor ability test was used to assess motor ability. Results showed that the chronological age was significant for the variable of motor abilities. Also, the relative age was significant for the variable of motor abilities. Comparison of means showed that the students born in the first and second quarters have a higher mean motor ability than students born in the third and fourth quarters. Also, students born in the fourth quarter have the lowest average motor ability. Results showed that the relative age on chronological age was significant. Therefore, female students for each of the age groups in the first and second quarters of the year have the highest score of motor ability, and female students in the age groups of 7-8 years, 9-10 years.
