The present study aimed at investigating the effect of rich environment athome on the speed of acquisition progress in football dribbling skill of boys.The statistical population included children aged between 6 and 13 in district1, Tehran city. The present study was semi-experimental with pretestposttestdesign. Based on the results of the distributed questionnaires, 30subjects were selected as the sample and were divided into two groups: richand non-rich. Firstly, both groups participated in football dribbling test as thepretest. Then, both rich and non-rich groups received training for 9 days andone session per day. At the end of each training session, both groupscompleted football dribbling test again. To compare the groups, the 2 × 9mixed analysis of covariance was used, and dependent t test was applied toexamine intragroup changes. Wilks Lambda index indicated that the effect ofenvironment on the speed of learning progress was significant(F(9&19)=3.27), P<0.014, correlation ratio=0.608). The rich group had ahigher speed of learning progress than the non-rich group. The comparisonof the training days of both groups showed that the rich group wassignificantly better than the non-rich group for all days except for day 4. Theresults of dependent t test showed a significant difference between pretestand day 9 in rich (P<0.001) and non-rich (P<0.001) groups. Overall, theseresults show that enriched home environment significantly improves thespeed of learning progress.

According to numerous studies in sport psychology, it is proved that optimal athletic performance relates to many psychological factors and personality and psychological characteristics influence athletic development. The aim of this study was to investigate and compare mindfulness, emotional intelligence and mental toughness in successful and unsuccessful karate athletes in Iran men’s karate super league. This research was casual-comparative and the population consisted of Iran men’s karate super league in Kumite section in 2015. Primary data were collected by convenience sampling method from 70 athletes of all participating teams- especially two high ranking teams and three low ranking teams- in karate super league. After the data of the number of competitions and their results for each athlete were collected, the optimal performance of karate athletes was calculated and two successful and unsuccessful karate athletes groups were determined (each group 30 subjects). The form of content, the demographic questionnaire, Sport Mindfulness Scale, Schutte Emotional Intelligence Questionnaire and Mental Toughness Questionnaire (48 items) were used. The normal distribution of data in both groups were examined using the K-S and Shapiro-Wilk tests. The results of independent t test showed that the difference in mindfulness was not statistically significant between successful and unsuccessful karate athletes, but the emotional intelligence and mental toughness between successful and unsuccessful athletes were significantly different. Overall, it can be stated that a major part of these findings emphasize the role of the psychological characteristics in the sport performance and success of the two groups of elite karate athletes who have the highest rank in Asia and world karate.

The aim of this study was to investigate the effect of feed forward augmented information in model observation on learning mini basketball free throw skill in children. For this purpose, 45 children (10 years old) were selected as the sample by convenience sampling method and were divided into three groups: feed forward augmented information + observation, observation + KR feedback, and control (C). The research method was semi-experimental and research design was pretest-posttest and retention test. The task used in this study was mini basketball free throw skill. Firstly, the participants performed 15 trials in the pretest. The acquisition phase consisted of 6 blocks of 15 trials of observation followed by physical training. The retention test was performed 48 hours after the last training block in 15 trials. The data were analyzed by mixed analysis of variance, between-group analysis of variance and Tukey post hoc test. The results showed that both at the acquisition and retention phases, feed forward augmented information + observation group who were knowledgeable about the quality of the model prior to the observation showed better performance than the other two groups (P<0.05). Generally, these results showed that knowledge of the model performance before observation can make learning of a throwing task more significant than the time when they were knowledgeable after the observation. Therefore, it is suggested that feed forward augmented information on the quality of the model before observation should be used to improve the performance of the subjects.

Neonatal growth indices are one of the important issues in the assessmentand care of pregnancy which have significant effects on the life after birth.Therefore, it is important to recognize their related factors. The aim of thisstudy was to investigate the relationship between pregnant women's lifestyleand physical growth indices in newborns. This descriptive-comparativestudy was conducted on 412 pregnant women (mean age 28.1±5.6 years)who referred to Mahdieh Hospital in Tehran by a cross-sectional and fieldmethod. Subjects were selected by convenience sampling method. Data werecollected and recorded by Lifestyle Questionnaire (LSQ) and informationabout the growth indices of newborns from their medical records in TehranMahdieh Hospital. Then, growth indices were compared with NCHSstandard norm (P≤0.05). Independent and one-sample t tests and Pearsoncorrelation were used to analyze the data. According to the results, thequality of lifestyle in pregnant women was reported to be moderate. Also, acomparison of weight and height indices showed a significant difference inthe time intervals after birth in comparison with the NCHS norm (P≤0.05)which indicated that this norm was lower than the global norm in Iranianinfants. On the other hand, no significant difference was observed in thehead circumference (P=0.18). Considering the findings of this study onlifestyle and moderate physical activity in pregnant women, mothers arerecommended to have more physical activity and to improve their nutritionalquality so that they can promote their lifestyle and thereby improve thegrowth indices of newborns.

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 aim of this study was to examine the positive effects of forced andvoluntary exercises as a non-pharmacological factor on modified behaviorsdue to stress of separation from mother. In the present study, 48 male babyrats were selected and separated from their mothers from day 2 to 14 for 180minutes. On the 21st day, these rats were randomly divided into 4 groups.The groups included maternal stress, control, treadmill, running wheel (RW).The first group experienced stress of separation from their mothers from day2 to 14 and the control group was kept from the beginning with theirmothers. The exercise groups also began to exercise since their 21st birthday. Then, the groups conducted behavioral anxiety and rodent depressiontests including EPM, Splash, FST, and Open Field. The obtained data werestatistically analyzed by t and ANOVA methods at a significance level(P<0.05). Behavioral tests showed that the stress of separation from themother caused depression behaviors. On the other hand, voluntary exercisecaused antidepressant effects compared with the stress group while nosignificant changes were observed between the effect of forced exercise andthe stress group. The results showed that exercise, especially voluntaryexercise, reduces stress during adolescence, and reduces depression andanxiety behaviors in adulthood.

Attention deficit/hyperactivity disorder (ADHD), is one of the common neurodevelopmental disorders in children, can produce several cognitive, social and educational difficulties. The purpose of this study is to investigate the effect of fundamental motor skills (FMS) on cognitive impulsivity, motor impulsivity and sustained attention in primary school children with attention deficit/hyperactivity disorder symptoms. The research method was quasi-experimental with pre-test-post-test design. The study population consists of all elementary school students of Shiraz schools. The sample used for the study was 38 students with ADHD symptoms which was selected by multi-level sampling based on SNAP-IV and randomly divided in two groups, experiment (21 subjects) and control (17 subjects). The experimental group trained for ten sessions in the FMS program and the control group dealt its daily activities. Then one session before and after of interventions all of the two groups were measured with using of continuous performance, dexterity, porteus maze and passing test. Data were analyzed by mixed repeated measures ANOVA and indicate that FMS training can have a positive effect on children performance in motor impulsivity, but there was no evidence of the effect of mentioned interventions on Cognitive impulsivity and sustained attention. According to the findings of the study, can be concluded that short term FMS training can be useful in controlling movement and impulses in children with ADHD symptoms.

Children with intellectual disability experience many problems in theireveryday lives and educational issues. One of these important issues exists invisual perception. Therefore, the aim of the present study was to examine theeffect of sport vision training on visual perception of children withintellectual disability in Isfahan city. 30 children were selected fromeducable students with intellectual disability (7-11 years old) as the sampleand were randomly assigned to two groups (each group 15 subjects):experimental and control. Before the training, children with intellectualdisability underwent Wechsler IQ test and educable children entered thestudy. Also, before the training, the TVPS - II visual perception pretest wasadministered. Then, experimental group had their training for 8 weeks, 3sessions per week and 45 minutes each session. In the final stage, TVPS - IIvisual perception pretest was conducted. Based on the results of theMANCOVA analysis (with the control of pretest scores) sport visiontraining had an effect on the mean of all visual perception componentsexcept for form constancy test in the posttest (P<0.05). The results of thisstudy showed that sport vision training can improve the visual perception ofchildren with intellectual disability. Therefore, it is suggested that sportvision training is also used to treat and rehabilitate these children in thetreatment process.
