Introduction: The present study aimed to investigate the effect of a course of Taekwondo goal-oriented physical exercises on the cognitive functions of children with learning disorders.
Methods: In this quasi-experimental study, which was conducted with a pre-test-post-test control group design, 20 boys with learning disorders were selected from the centers for learning disabilities by referring to special education in Mashhad. In the pre-test stage, the participants' working memory and inhibition were measured by N-back and Stroop tests, respectively. After that, the exercise group participated in the selected Taekwondo exercise program for three 50-minute sessions per week for four weeks. In each session, a set of My Brain cognitive games was used before the implementation of the exercise protocol. In the first 10 minutes of the session, cognitive games were played, then 10 minutes of warming up, 30 minutes of teaching and practicing Taekwondo techniques, and finally 10 minutes of cooling down were conducted. During this period, the control group did their usual activities. Finally, the dependent variables were measured again in the post-test phase. Repeated measures analysis of variance test was used for statistical analysis.
Results: Taekwondo goal-oriented physical exercises improved cognitive functions in the Exercise group; All these changes were significant compared to the control group (P<0.05).
Conclusion: Taekwondo goal-oriented physical exercises can be effective as an intervention to improve the cognitive functions of this group of children.

Introduction and Purpose: the purpose of this study was to examine the effect of sport vision training on accuracy and targeting-interceptive skill quiet eye in children with learning disorder.Methods: In this semi- experimental study with a repeated-measure design, 30 boys aged 7-10 years with learning disorder were divided into sport vision and control groups. In the pre-test phase, participants performed 10 trails to throw and catch task the ball. Acquisition phase have done in eight weeks and three sessions in per weeks. At the end of the last training session, in the post-test phase, in two weeks of detraining in the retention and transfer phases, the participants performed 10 trials to throw and catch task the ball. At each phase, the gaze behavior was recorded by eye tracker system and the throw and catch task performance was recorded by the researcher. Data were analyzed by analysis of variance with repeated measures with 0.05 significant levels.Results: The results indicated that sport vision training has a significant effect on increasing the accuracy of targeting-interceptive skills and on increase quiet eye period of throw phase. But, other result indicated that sport vision training has not effect on quiet eye of catching phase.Conclusion: In general, the results of the current study emphasize the importance of sports vision training on the performance of children with learning disabilities; However, more research is needed on the effect of sports vision training on gaze behavior according to the type of task (targeting or interceptive).

Introduction: Children with learning disorder have more inefficient use of gaze strategies in various tasks.Purpose: The purpose of this study was to examine the effect of quiet eye training on muscle activity and targeting-interceptive skill accuracy in children with learning disorder.Methods: In this semi- experimental study with a repeated-measure design, 30 boys aged 7-10 years with learning disorder were divided into quiet eye and control groups . In the pre-test phase, participants performed 10 trails to throw and catch task the ball. Acquisition phase have done in eight weeks and three sessions in per weeks. In per session after the video-gaze exercises, 10 trials were performed to throw and catch task in accordance with the gaze exercises instructions. At the end of the last training session, in the post-test phase, in two weeks of detraining in the retention and transfer phases, the participants performed 10 trials to throw and catch task the ball. At each phase, the selected muscle electrical activity was recorded by electromyography and the throw and catch task performance was recorded by the researcher. Data were analyzed by analysis of variance with repeated measures with 0.05 significant levels.Results: The results indicated that quiet eye training have a significant effect on increasing the learning of targeting-interceptive skills and on reducing the muscles electrical activity.Conclusion: The results of this study support the pre-programming hypothesis on the importance of planning and choosing the correct answer.
