Abstract
The purpose of this study was the comparison of the required time and repetition for the acquisition of simple and complex timed motor sequenced task (TMST) among various practical conditions and determination of suitable practical methods with respect to individual characteristics. One hundred and fourteen university students, with the age range of 19-25 years old, were divided in 4 groups according to Raven Intelligence test, Achievement Motivation Test, Reaction time and Purdue pegboard, and based on the first, second and third quadrants. Then they were randomly placed in one of the two groups of simple and complex TMST and also in one of the practical conditions of the interaction of the organization of practice (random, blocked, constant), and practical distribution (massed, distributed). The subjects trained 6 days under their specific practical condition of simple or complex TMST, in a way they reached to the acquisition criterion (accuracy %75, timing %25, stability %15) in a practical training block. The number of repetitions and passage of time before this criterion block were considered as the minimum required time and repetition for acquisition of TMST. The data were analyzed using two-factor analysis of variance, independent t-test and Xi - 2 test (=&alpha0.1). The results showed individuals with different characteristics have acquired simple TMST in blocked and massed condition (except group ) in average within 30 repetitions and 1347 minutes, and complex TMST in random and distributed condition (except group ) in 25 repetitions and 1228 minutes. In addition, the findings showed that the principles of practical programming is affected by both the complexity level of task and individual characteristics. At last, it seems there is a need of more studies on the combination effect of the environment, individual and task on the acquisition fine motor skills.

Abstract
Tools and methods that could lead to the recognition and motion analysis variables are helpful in understanding the movements and movement Sciences and It will be a vital part of movement and sport sciences laboratories. "Human motion analysis instrument based on joints angles in sagittal plane" was designed to provide information about the motion analysis that offers to researchers, educators and therapists. Once the instrument has been built according to the design of specialized electronic and mechanical engineers, tested until the fourth final design was made and it was registered on 21.05.1393 with number 83557. To check the validity, with using of motion analysis system with optoelectronic cameras and the instrument, 20 participants (10 males and 10 females) were asked to perform a throwing task. The root mean square error (RMSE) and Pearson correlation in the statistical 0.01 were used to assess the reliability and validity. The results indicate that the instrument is made applicable and appropriate validity and reliability so that the validity: 0.98 and reliability: 0.95 was reported.

Abstract
In this correlational study, physical activity of girls’ has been predicted using ecological approach. For this purpose, 374 girls aged 10-12 years selected and completed Self-report questionnaire and physical activity children with reminders 7 days (PAQ-C), Perceived physical competence questionnaire (PPFS), Perceived School Climate Questionnaire for physical activity (Am & et al,2005) and Social Support Questionnaire (Grier and et al, 2008). The BMI index and Lincoln Oseretsky Motor Skills Test was calculated for all subjects. Multiple regression analysis showed Children's fitness, physical competence, perceived climate of the physical environment and social support of friends and family (social environment) are significant predictors for amount of children's physical activity (P <0.5). In this regard, based on effect coefficients it would be say that Fitness (10%), physical competence (15%), Motor Skills (12%), physical environment (23%) and social environment (24%) can predict children's physical activity. According to results, it would be suggested using the well- known ecological variables to predict children's activities.

Abstract
The purpose of this inquiry was to examine the interrelations among handwriting legibility and speed, and underlying perceptual-motor skills in Persian language students. Seventy students (26 male, 44 female; 10.21 ± 1.02 yr; 30 poor and 40 good control hand writers) were assessed during a copying task. The children completed the visual-motor control (VMC), upper-limb speed and dexterity (ULSD), and upper-limb coordination (ULC) subtests of the Bruininks–Oseretsky test of motor proficiency (BOT). The poor group scored significantly lower on handwriting legibility and speed in comparison with classroom controls in the copying task. Correlation coefficients between perceptual-motor function scores with handwriting legibility, and with handwriting speed varied from -0.11 to 0.40, and 0.17 to 0.39 respectively. Results showed that both legibility and speed predicted differences between students classified as “poor” and “good” hand writers. Results also showed that in the poor hand writers group, age, gender, BOT-ULC, and BOT-VMC were found to be significant predictors of legibility of handwriting, whereas gender and BOT-ULC were shown to be significant predictors of handwriting speed. The findings suggest that distinct perceptual-motor components may underlie writing during copying. Poor quality of handwriting of children seems to be particularly related to some sort of deficiency and dysfunction in perceptual-motor skills. Future studies should determine the possible benefit of interventions including stimulant in perceptual-motor functioning and handwriting performance, to enhance performance in these areas.

Abstract
The prevalence of autism spectrum disorders (ASD), as a developmental neurological condition, has increased in recent years. The present study aimed to investigate the effectiveness of cognitive-motor exercises on the improvement of some large and delicate motor skills of children with autism based on Gentile's Two-Stage Model. In the present Semi-experimental study, one of the rehabilitation centers under the supervision of Tehran Welfare Organization was selected as via the convenience sampling method and 20 children aged 6-10 years with autism were randomly divided into two homogeneous experimental and control groups. The subjects in the experimental group participated in a six-week training protocol (three sessions per week). Each session was made up of 60 minutes of cognitive-motor exercises based on Gentile’s model. Bruininks-Oseretsky subtests of motor proficiency were employed for data collection. The collected data were analyzed using the repeated measures ANOVA. The results indicated that after cognitive-motor training, running and agility skills, static and dynamic balance, upper limb coordination and response speed in the experimental group increased significantly (p<0.05). As the findings showed, cognitive-motor exercises designed as a useful method can be used to rehabilitate the fine and gross motor skills of children with autism.

Abstract
The purpose of this study was to examine the effect of motor dependent/independent visual perception training on visual-motor integration and fine motor skills of 7-8 year old children .For this purpose, 107, 1st grade primary school students in Sabzevar were selected through purposive sampling (with equal economical and cultural status , optimum mental and physical health and full sight with or without wearing glasses) and randomly divided into two experimental (no=32)and a control group (no=43). After attending a pre-test session, one of the experimental groups was trained in movement dependent visual-perception tasks while the other group performed movement independent visual-perception tasks. Both groups performed their tasks for three sessions, 45-minute per week and for six consecutive weeks. Shapiro-Wilk and Levin test results confirmed the normality and homogenity of data and ANCOVA showed that both training programs significantly improved visual-motor integration and fine motor skills of 7 to 8 years old children. However, Bonferroni test indicated that there were no significant differences between the movement dependent and independent training programs. The data analysis was performed by using SPSS 19.0. The results of this study confirmed the purposed "movement" hypothesis stating that the significant contributor to the development of perception and perceptual-motor components is not the active or passive movements of the individual, but rather it is the attention of the person to the visual stimuli within the environment.

Abstract
This study aimed to address agreement level of performances on 3 selected motor skill assessment tools in a sample of Iranian first to fourth graders aged 7-10 year olds. The convenience sample included 164 healthy girls from public schools. A Pearson correlation coefficient was calculated on the association between MABC-2, KTK and TGMD-3 performances in graders. A one-way multivariate analysis of variance (MANOVA) was conducted to compare performances means across grade levels. Low-to-moderate correlations were found between assessments across age in each assessment. In general, girls demonstrated higher scores across age cohorts. In conclusion, low-to-moderate associations among assessments instruments provide different pictures/levels of motor competency and should not be used interchangeably in studies.
