The aim of this study was to investigate the effect of 10 weeks of shadow play on preschool children's fundamental movement skills. In this quasi-experimental study with pretest/posttest design and a control group, 28 girls and boys (6 years old) were selected by convenience sampling method from children in a preschool and were randomly divided into the experimental group (5 girls & 9 boys) and the control group (5 girls & 9 boys). For 10 weeks (three 45-minute sessions), the experimental group performed the shadow play and the control group had their routine activities of preschool. The pretest and the posttest were administered by "the Movement Assessment Battery for Children-Test (M-ABC)". This test consisted of three subtests of manual dexterity, ball skills and balance skills. Analysis of data was performed by covariance analysis (α=0.05). The results showed that 10 weeks of shadow play had a significant effect on subtests of manual dexterity, balance skills and the total score of fundamental skills but had no significant effects on ball skills. Findings of this study showed that shadow play may improve preschool children's fundamental movement skills.

A match of the students' traits and teaching and training styles of sport skills has received researchers' attention. The aim of the present study was to investigate the interaction of physical self-concept and coach-oriented and self-regulated training styles in acquisition, retention and transfer of volleyball serve of collegiate female students. 50 female students (age: 18-25) were assigned to high and low physical self-concept groups. Then, each group was divided into coach-oriented and self-regulated styles. Participants exercised the criterion task for 6 weeks, 4 sessions per week in their special training condition. AAHPERD test and Physical Self-Concept Questionnaire were used for data collection. Acquisition tests were administered every week while retention and transfer tests were administered 3 days after the last training session and one hour after the retention test respectively. The data were analyzed by ANOVA with repeated measures and ANOVA. Results showed that the high self-concept group practicing the task with self-regulated style showed the best performance in acquisition, retention and transfer phases. The other groups showed similar performances. Results clearly showed that participants with high physical self-concept who exercised volleyball serve skill with self-regulated style had the highest skill acquisition and learning.

Abstract
The aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, ...

The aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, left–handed-explicit, and left–handed-implicit. Participants’ task was accuracy and time of sequential reaction. Acquisition phase consisted of 800 practice trials. Participants in explicit practice groups were aware of the arrangement included in stimuli while implicit practice groups were not informed about this arrangement. The day after the acquisition phase, retention and transfer tests were taken. Multiple ANOVA showed that regardless of handedness, implicit practice had more effects on learning reaction time in all three phases of acquisition, retention, and transfer than explicit practice. Regardless of practice type, comparison of right–handed and left–handed subjects was significant in response accuracy in acquisition phase as left–handed subjects were more accurate. The counter effect of handedness and practice type on reaction time and response accuracy was not significant, that is to say right–handed and left–handed subjects had no significant differences in explicit and implicit practice.

The aim of the present study was to determine the validity and reliability of the Movement Assessment Battery for Children Test (M-ABC Test) for 6-year-old children of Isfahan city. 306 children participated in the study. Inter-rater reliability of the M-ABC test was estimated using two trained observers with 50 children. Test–retest reliability was assessed using 30 children with a one-week interval. To determine construct validity of this test, explanatory and confirmatory factors analyses were used. Agreement between testers was great with a mean intra-class correlation coefficient of 0.98. The mean intra-class correlation coefficient of 0.77 was obtained for test–retest reliability. Three-factor structure of M-ABC test and proper assignment of skills to manual dexterity, ball skill and balance factors were supported for this population. The According to these results, M-ABC test can be applied to assess fundamental skills of 6-year-old children of Isfahan city.

The present study was designed to determine the effect of different levels of body mass index (BMI) on fundamental motor skills in 6-year-old children of Isfahan city. For this purpose, fundamental motor skills of 19 underweight children (grade 3 thinness) and 19 children with normal weight and 19 overweight children who were matched according to their gender and socioeconomic background were assessed using the Movement Assessment Battery for Children (M-ABC). Among 8 items of M-ABC, normal weight and overweight children differed on only one-leg balance with preferred leg and normal weight and underweight children differed on only walking heels raised item. However, the total motor impairment score which was calculated by the summation of the 8 item scores was higher in underweight and overweight children than their normal weight peers.

The purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. Participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor KR) groups. They practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respectively with regard to relative and absolute timing. Self-control group received KR about the model's performance whenever they requested it whereas the other groups (yoked, instructor) had no control on the feedback schedules. They performed 72 trials during the acquisition phase and 12 trials in retention and transfer phases. ANOVA with repeated measures and a multi-factorial ANOVA were conducted to analyze the collected data. The results demonstrated that during the acquisition phase, relative timing errors were lower in the self-control and instructor groups. During the retention and transfer phases, relative timing errors were lower for the self-control compared with the yoked and instructor groups. In addition, during the retention and transfer phase, absolute timing errors were lower for the yoked compared with the self-control group.

The purpose of this study was to study the matching of the competitiveness trait and kind of training condition when learning a sport skill (basketball free throw). 60 male university students (age 21.76±1.5 years) participated in this study and were divided into two homogeneous groups based on their pretest scores. As a result, four training groups were used in this study. Sport Orientation questionnaire (reliability coefficient: 0.90) was used to determine the subjects’ competitiveness and non-competitiveness trait. The questionnaire was confirmed by Bahram. Groups performed the criterion task in a competitive and non-competitive condition for 10 sessions (15 trials each session). The basketball free throw test (EEHPERD) and Sport Orientation Questionnaire (SOQ) were used to gather the data. Posttest was performed after the final session and retention test 10 days after the posttest. To analyze the data, analysis of variance with repeated measures, ANOVA and post hoc tests were used at a=0.05. The results showed that competitiveness subjects performed better in the competitive condition and non-competitiveness subjects performed better in the non-competitive condition. The findings also showed a significant decrease in the retention test in the non-competitive condition group. The results of this study supported Zone of Optimal Function (ZOF) hypothesis and Interactionism approach.
