The aim of this study was to compare the effectiveness of perceptual motor training and cognitive games on cognitive development in mentally retarded children. In this experimental study, 45 mentally retarded children aged between 8 and 12 in Kermanshah province were randomly divided into 3 groups: perceptual motor training, cognitive training and control. The perceptual motor program included the protocol of Salari et al. (2014) and Kashi et al. (2015) and cognitive games included a collection of cognitive games of my brain that was run as software. The groups participated in the program for 8 weeks, 2 sessions per week and 45 minutes per session. Before and after the training, they participated in London Tower computer test and the Stroop color-word test as pretest and posttest. Data were analyzed with Mancova and Ancova tests.The findings of the study showed a significant difference among perceptual motor training, cognitive games and control in London Tower computer test and Stroop color-word test. Perceptual motor training had a greater effect on the improvement of cognitive functions in mentally retarded children than cognitive games. Therefore, it can be concluded that although both types of games play an effective role in improving cognitive development and can be used to improve children's well-being, perceptual motor training is a better tool to create more development effects than cognitive training.

The aim of this study was to examine the effect of a course of physical exercise on cognitive function and Brain-derived neurotrophic factor in children with Attention Deficit Hyperactivity Disorder (ADHD). This research was performed semi-experimental. Participants included 25 male students aged 7 to 10 years old referred to Ibn Sina Hospital in Mashhad, and randomly divided into two groups (control and experimental). The experimental group participated in an exercise program for 24 sessions, 75 minutes per session. The control group did not receive any intervention. All the participants performed Stroop Test and Go no go Test before and after the exercise. Also, blood samples were taken from these participants to measure serum BDNF before and after exercise. The data were analyzed using ANCOVA. The results demonstrated that cognitive function of the children in experimental group regarding Stroop and Go no go tsts showed significant difference compared with the control group, also Serum BDNF levels showed a significant increase (p<0.05). These results suggest that the organized exercise program helps to improve cognitive function and treat in children with ADHD.

The purpose of this study was to compare instructor-based and parent-based interventions on motor development in 7 to 10 years old children with developmental coordination disorder. Participants consisted of 84 girls and boys from 8 elementary school at 4, 8 and 13 Tehran educational zones; they were screened by developmental coordination disorder questionnaire, then randomly divided into three groups: instructor-based, parent-based, and control. Two experimental groups carried out skills training for 12 weeks consisting, 36 sessions, each session 45 minutes. All participants were assessed before and after interventions with Movement Assessment Battery for Children; Second Edition. The result of MANCOVA and ANCOVA tests showed that both experimental groups significantly in the total score of motor development (p≤0.05) and its components (manual dexterity, balance, aiming and catching) had higher score than the control group (p≤0.017), and of course Instructor-based group in the aiming and catching subscale had better performance than parent-based group (p≤0.05), that demonstrates positive impact of group environments. In summary, although both interventions help to improve motor development in children with developmental coordination disorder, instructor based intervention is more beneficial in some of the components of motor development.

The aim of this research was to determine the effect of selective exercise training on reducing the symptom of hypotonia and changing body composition in Down syndrome adults. The research was performed in Nemoneh Disability Rehabilitation Centre of Tehran. 24 men with Down syndrome (mean age 26.185± 3.933) were randomly assigned to either a control (n=11) or an experimental group (n=13). The Experimental groups followed selective exercise training for 12-weeks, three times a week. Result of this research showed that after 12 weeks selective exercise training, body fat percent had a significant reduction (P<0.05) and soft lean mass and muscle performance (in 5 from 6 tests for assess muscle strength, endurance and power) had a significant increase (P<0.05). The results of this study showed that this type of exercise training significantly improves the health of Down syndrome adults by reduce in extra body fat percent and increase in muscles tissue and performance and in this way; it will reduce the symptoms of Down syndrome for benefit of improved physical health.
