Abstract
The purpose of this study was to determine the effect of two different age groups (children and young adult) to learning of temporal-special coordination hand movement pattern. Sixty subjects according to the age (children – young adult) and receiving feedback (100%, omitted, self-control) were randomly divided into six groups. This study was done in three days. All subjects practice 100 trails of movement task in each day of first and second days. Retention tests were done in second and third days and reacquisition test was done in the third day. Analysis of variance (ANOVA) with repeated measures and two way ANOVA was used to data analysis. All participants in the first day improved their accuracy across practice trials. In the second day children did not improve their accuracy but young adult experienced improvement across practice trials. There was not significant difference between retention children tests but that was significant about young adult. During the retention tests children who received 100% feedback was significantly better than other children feedback groups and there was no significant between young adult feedback groups. During the reacquisition test children who received 100% feedback was significantly better than other children feedback groups and there was no significant between young adult feedback groups. Results from this study showed young adult are better than children in the learning of this pattern, receiving more feedback can improve motor learning in children (in contrast with guidance hypothesis) and we must not expect motor skill acquisition occur in children like young adult.

Abstract
Individual constraints are of the factors that can effect on motor development. The aim of this study was to investigate the relationship between motor proficiency with body mass index and nutritional status in healthy boys 10-14 years old in Tehran. Statistical sample was of 120 children for BMI and 90 children for nutritional status. body mass index groups, lean, normal, overweight and obese groups nutritional status to malnutrition, average feeding and Appropriate division Who were chosen by cluster purposeful and motor proficiency was assessed using the by BOT-2 test. The results showed that the between conditions BMI, lean and normal, normal and obese, overweight and obese, there is a significant difference in motor proficiency but in other cases, the difference was not significant. As well as between conditions of malnutrition and normal nutrition, normal nutrition and proper nutrition, proper nutrition and malnutrition, there is a significant difference in motor proficiency. According to this result, body mass index and nutritional status of children in this age affects motor proficiency, which may be different BMI groups in motor proficiency in geometry and mass of body parts, mechanical factors attributed and differences in nutritional status groups to the role of food items brain growth and physical development, he said.

Abstract
The movement imagery helps to learn various sports skills if persons have a reasonable imagery about how doing that skill and the command be carved on the brain. The main aim of the current study is to investigate the visual and content validity as well as the reliability of the Persian version of the Movement Imagery Questionnaire for Children MIQ-C. The main questionnaire was translated into the Persian by using the Translation-back Translation method. In order to standardize and validate the questionnaire, 10 elites in the field of the motor imagery and sports psychology, filled the questionnaires in order to determine the content validity ratio (CVR) and the content validity index (CVI). After a primitive study, the necessary modifications were applied.The questionnaire reliability was investigated by the test-retest reliability method and the Cronbach's alpha. Results indicated that the CVR and CVI are 0.62 and 0.79, respectively, which confirms the validity of the questionnaire. The reliability was confirmed by the internal consistency method which value was obtained higher than 0.7. For evaluating the ability of children in motor imaginary, a reliable method should be used.According to obtained results of the current work, the questionnaire benefits from a suitable reliability and validity.

Abstract
Non-generic feedback refers to a specific event and that task performance is the reason to the acquisition of skills and implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. The Goal of this study was to determine the generic and non-generic feedback effects on children’s motor learning basketball free throw. This research was semi-experimental. For this purpose, sixty children of Tehran (30 girls and 30 boys) aged 9-13 years participated in the study and were randomly divided into four groups of 15 individuals. Subjects performed six basketballs free throw in the acquisition (Two blocks of three trials). Which after the third throw, according to the group of subjects received a positive feedback (generic or non-generic) and also after the Sixth throw, negative feedback. After half an hour was immediate retention in the same way. Data were analyzed by using two-way ANOVA and repeated measures. Results showed that non-generic feedback was significantly more effective than generic feedback and shows more improvement in Performance. The present results demonstrate the importance of the wording of feedback, although these terms might not have an immediate effect on performance but by enhance motivation, poor performance is purportedly.

Abstract
Birth weight is one of the most important indicators of neonatal health in any society and is considered as the best tool to measure the outcome of pregnancy and the most important factor in determining the incidence of disease or death of the infant. The purpose of this study was to investigating relationship between visual impairments and motor problems in children 3-6 age with very low birth weight and extremely low birth weight. The participants of this study were 88 children, 54 children with very low birth weight and 34 children with extremely low birth weight who were selected as available. The MABC-2 test were used evaluated motor performances and visual functions such as visual acuity, contrast sensitivity, Stereo acuity, Strabismus, nystagmus, Accommodation, convergence and visual perception measuring by a pediatric ophthalmologist. Pearson correlation coefficient test with bootstrap confidence intervals was used to examine the relationship between each of the visual measurements and motor function. Also, a two-string point coefficient was used to determine the relationship between motor function and eye deviation and nystagmus. The results showed that the rate of visual and motor disorders in the two groups of preterm children was high compared to the healthy population, but there was no significant relationship between visual deficits and movement problems in the two groups of preterm children. This means that vision impairment does not lead to motor problems in preterm children.

Abstract
It has been shown in various researches that the focus of attention and quiet eye duration (QED) are effective variables on the performance of targeting tasks. However, the impact of these variables on motor skills in children needs more research; Therefore, the purpose of this study was to investigate the effect of different attentional focus instruction on QED and accuracy of children's darts throwing. Participants such as twelve right handed children (age: M=8.83, SD=0.79) without dart throwing experience participated in the study; while their eyes movements were recorded by an eye tracker system, participants performed 18 dart throws (6 blocks of 3 trials) under three different attentional conditions: 1) an external focus, 2) an internal focus, and 3) control conditions. The result showed that effect of focus of attention was significant neither for accuracy nor for QED. Therefore, in order to be aware of the optimal focus of children, more research is needed in various motor tasks.

Abstract
The impact of IQ on academic achievement has been confirmed, but its effect on the effectiveness of motion interventions is unknown. The present study examines the effects of Indigenous- Local play on the Motor proficiency of children with high and low IQ. Therefore, using Raven's Inventory, among 13-13 year-old children in Tehran, 15 high-intelligence children and 15 low-intelligence children were selected and trained in Indigenous- Local play for eight weeks. Bruninx-Oseretsky test was used before and after the exercise to assess the Motor proficiency. The results showed that although both groups benefited from the intervention, the impact of intervention on children with high IQ was higher. The results of this study, with the emphasis on the use of indigenous-local play in schools for motor development, also recommends that sports talent specialists use intelligence as an indicator of talent identification.

Abstract
The aim of this study was to Compare Effectiveness motor proficiency of the nutritional status on men in different age groups ((children, adolescents and young adults)), respectively. Statistical Society study was for children all student ages 10-7 years, for adolescents all student ages 15-12 years and for Youth of all students 20-18 of Tehran University except the student physical education. The sample was 90 people in each of the age groups, the four elementary schools and four high schools in Tehran and Tehran University male students were chosen by cluster sampling. This study was a descriptive survey and comparison measurement was test of instruments anthropometric and Brvnynks- Oseretsky. The results showed that among malnutrition, moderate nutrition and proper nutrition in adolescence and adulthood motor proficiency was not statistically different ages but among children ages motor proficiency were significantly different. In addition, no significant difference between motor proficiency age groups. It seems due to the impact of nutritional status on motor proficiency, and this issue was observed in this study at an early age; therefore, children are the most vulnerable in this context and considering the nutritional status of children is very important.

Abstract
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 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.

Abstract
This study aimed to investigate the effectiveness of basic taekwondo exercises on the executive functions of children with a learning disorder. For this purpose, 20 boys aged 10 to 12 years with learning disorder in Mashhad were selected and randomly assigned to training and control groups. The training group practiced Taekwondo for 12 sessions, each session lasting 50 minutes, repeating three days a week. The control group also engaged in their normal daily activities during this period. Changes in subjects' cognitive functions were measured before and after the training period by the N-back and the Tower of London tests. Analysis of variance with repeated measures was used for statistical analysis. The results showed that basic taekwondo exercises improve executive functions in the training group; All these changes were significant compared to the control group (p<0/05). Therefore, based on the results of the present study, it can be concluded that basic taekwondo exercises help to improve the executive functions of children with learning disorder by affecting brain areas related to executive functions.
