Physical Self Concept can be affected from interventions such as sport and exercise training. So in order to enhancing the person`s physical characteristics perception and creation the partnership motivation in physical activity, it is important to know a bout the way of affecting this methods of training. Purpose: this study was designed to evaluate the effect of a progressive resistance training program on the physical self concept and body function of boys with cerebral palsy. Methods: Sixteen students [mean age 16.05 years (SD 1.2)] with spastic diplegic cerebral palsy were randomly divided in control (7) and experimental (9) groups. Participants in the experimental group completed a progressive resistance-training program (8 week) using three exercises to strengthen the major support muscles of lower limbs. Pre and post intervention, the physical self- concept was measured by the Physical Self-Description Questionnaire, and body function was measured by the balance test, walking test, stair test, and strength tests of Ankle plantar flexors, Knee extensors, Hip extensors. The data was analyzed via repeated measures and independent T-test.
Results: overall, the body function of experimental group showed a significant changes in balance test, walking test, stair test, and strength tests of Ankle plantar flexors, Knee extensors, Hip extensors (p<0/05). But, difference between the pre test and post test averages of  the experimental group in global physical self concept and their subscales was not significant (p>0/05).Conclusion: in order to change in physical self concept via physical activity, it is crucial to control the factors such as period of training, training context, intention of subjects and etc.

The purpose of this study was to predict competition result of judo players base on emotional intelligence and its subscales. To get this research done, a 70 person sample from Population of judo players of national leagues in 90-91 season were selected (age = 22.0 ± 3.36 year, judo experience 8.4 ± 2.33 year). The instrument which used in this research was emotional intelligence questionnaire of “Bar-on” that was completed by athletes prior to the competition. Then, the competition result of each athlete was recorded in the questionnaire by the researcher. To analysis the data, descriptive Statistics, independent t_test and logistic regression were used. The results indicate that there is a significant relationship between emotional intelligence and its subscales with the result of competition and also emotional intelligence including three of its subscales that is: emotional self-awareness, realization, and impulse-control, might be proper predictors of competition result in athletes. Therefore improving and developing of these subscales can be effective in increasing success chance in the athletes

The purpose of this study was to determine Psychometric aspects of the Persian version of Infant Movement Motivation Questionnaire (IMMQ) for infants of 3 to 11 months. In this regard, 528 parents and their infants (239 girls and 289 boys) in Tehran were selected as samples through the method of random cluster sampling. For this purpose, first by using a translation - re translation method, IMMQ was translated into Persian by 3 motor behavior experts and 2 English teaching specialists. Confirmatory and Exploratory factor analysis was used for the validation of questionnaire structure; Cronbach alpha coefficient was computed for internal consistency of questionnaire. Also, intra-class correlation coefficient under test-retest method was used to evaluate the temporal reliability of items. The results of Confirmatory and Exploratory factor analysis showed that IMMQ is multifactorial; so that, in total, four factors consisting activity, exploration, motivation and adaptability can explain % 53/32 of the total variance. Moreover, the fit indexes of the extracted model (PGFI = 0.71, NFI = 0.92, RMSEA = 0.078) were favorable and acceptable. Also, Cronbach alpha coefficient (α = 0/93) and intra-class correlation coefficient (r = 0.88) of the Persian version of IMMQ with 27 questions the like of original version, had acceptable internal consistency and temporal reliability. So the results showed that the Persian version of IMMQ can be used for clinical or research purposes as well as an educational tool for parents.

This study aimed to evaluate the direct and interactive effects of socioeconomic status and birth weight on Tehran children motor proficiency. : The present study was a cross-sectional research which conducted in April and May of 2016 and the study population included 4/5 to 6-year-old boys and girls with very low and normal birth weight from 2 and 19 districts of Tehran city that from which 132 children were selected through a  convenience sampling. In this research we used socioeconomic status questionnaire and Bruininks-Oseretsky -2 test.  obtained data were analyzed using two-way ANOVA. The results showed that motor proficiency in children with very low birth weight was lower than those with normal birth weight (P <0/001), and in terms of effect of socioeconomic status, results showed that motor proficiency of children with low socioeconomic status was lower than those with high socio-economic status (P <0/001) and there wasn’t any significant relationship between effect of weight on motor proficiency with effect of SES on motor proficiency (Interactive effects )(P = 0/633). Results of the study showed that high socio-economic status had the capability of adjustment the negative effects of low birth weight on motor development. But it couldn't has a meaningful reparative effect. Thus the emphasis on the role of socioeconomic status on health of children with very low and normal birth weight is important. Also doing intervention such as improving the quality of environmental stimuli and taking care of pregnant mothers and also awareness for prevention of birth of low weight children must be considered in applied programs.

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 purpose of this study was to examine the relationship between motor competence, cardiovascular fitness test and physical activity of adolescents with the role of mediation of perceived competence.  The research sample consisted of 386 adolescent boys. Perceived competence was measured using Physical Ability scale of the short form of the Marshall Self-Descriptive Questionnaire (2010). From the pedometer And physical activity questionnaire for older children was used to measure physical activity,  and using Bruininks-Oseretsky Test test for measuring motor competence and a 1600-meter test for cardiovascular fitness test. The results showed a significant correlation between motor competence, perceived competence, cardiovascular fitness test and physical activity. Perceived competence  mediates association between motor competence and physical activity, fitness and cardiovascular fitness test. Finally, the results of the model showed that perceived competence had the most impact on the participation of adolescent physical activity. Also, motor competence has a greater effect on cardiovascular fitness test than perceived competence. According to the results of the research, educational programs should be designed and designed according to the importance of motor competence and perceived competence to improve participation of physical activity and physical fitness of adolescents.

One of the recent research challenges in the field of attentional focus instructions, are the study of its effects on the performance of elite athletes in continuous tasks. The aim of this study was to compare the effects of different attentional focus instructions on performance of agility in elite futsal players. Participants included 12 elite futsal players (mean age 23.91±1.56) that were selected from the first league of Division Qom via convenience sampling method. Participants were asked to perform the agility L run test under three attentional focus  instructions (the internal, external and control) in three trials. Rrepeated measure Analysis of Variance and paired t test were used for analysis of data. The results showed a significant effects of the type of attentional focus  instructions on  test execution time. Analyses showed that performance in the external focus of attention was higher than the internal focus conditions. Also, the result demonstrated that there is no significant difference between internal focus of attention and control conditions, and also between external focus of attention and control condition. The results of this study provide evidence that in skilled athletes, executing the continuous tasks improve through verbal instructions that conduct focus of attention externally.

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.

One of the most important issues for the elderly is the issue of physical health and cognitive problems. The aim of this study was to compare the activity of dual resistance-cognitive task with different intensities on fatigue, balance and cognitive function of elderly women. The present study is an applied and quasi-experimental method with the presence of 20 elderly women aged 60 to 70 years, which was done as a one-session test and getting answers. Subjects performed exhausting tests of foot press with machine and shoulder press with dumbbell with combined cognitive load with two different intensities (70% 1RM with low cognitive load and 30% 1RM with high cognitive load) in two days with an interval of 48 hours and the results were recorded. Balance test, upper and lower torso muscle activity and Stroop test were measured. The results of fatigue time, cognitive test and balance were significantly different between the two intensities (p <0.05). But in relation to the middle spectrum of muscle frequency, no significant difference was observed between the two intensities (p> 0.05).  Using low-intensity, high-cognitive exercise is more effective in treating upper body fatigue, which puts more pressure, which may need further investigation to evaluate the long-term success of these programs.
