Fundamental motor skills are key components of motor development and are divided into two main sub groups including fine and gross motor skills. The main purpose of the present study was to determine the effect of balance training with Swiss ball (BTWSB) on gross motor skill of Children with Attention Deficit – Hyperactivity Disorder. Participants of the present study were three 6 to 8 years old children with Combined type of Attention Deficit – Hyperactivity Disorder (ADHD-C). This study was a single-subject study with multiple baseline design. Participants were required to exercise BTWSB for 9 weeks. Change in the gross motor skill of participants was assessed at one-week intervals using multiple baseline method. We administered Conners Parent Rating Scale (2003) and Broininks – Oseretsky Test Of Motor Proficiency (1978) to assess each outcome variable. The results of the data chart analysis based on descriptive statistics and visual analysis showed that BTWSB improved gross motor skill of all three participants (PND = 100% for all three participants). The results of this study indicate a positive effect of BTWSB on improving gross motor skill of Children with Attention Deficit – Hyperactivity Disorder.

The aim of this investigation was to compare the level and the pattern of attention demands of a volleyball jumping serve using a probe reaction time (RT) technique. 14 junior elite volleyball players performed 60 jumping serves (JS) with their preferred hand. Jumping serve was performance as the primary task and verbal RT that was administered in four probe positions (PP) as secondary task. Results indicated a non-linear attention pattern in the performance of jumping serve so that probe RT was highest in pre-shot in run up (PP1) and in landing (PP4) while it was lowest in pre-jump stepping ahead (PP2) and pre-striking (PP3). According to the results, attention level in failed serves was lower than successful ones while the attention pattern was similar. It was concluded that attention deficit might be one reason for failing serves.

The aim of the present study was to examine the effect of goal setting on learning volleyball serve in novice female university students. The study included 20 female students (aged between 20 and 22 who were not physical education students with no volleyball history) who were randomly assigned to a goal setting or no goal setting group (n1=n2=10) using pretest scores. No goal setting group was provided with feedback on their performance while goal setting group received goal setting programs as well as feedback on their performance in training sessions. In the determined training condition, the two groups performed the task for 11 sessions, 20 trials each session. Both groups performed a pretest before the training protocol, acquisition tests during all sessions, an immediate retention test immediately after the last exercise session, and a delayed retention test after 10 days after the immediate test. AAHPERD volleyball serve (1976) was used to test the performance of the participants. Analysis of variance (ANOVA) with repeated measures, independent and paired t tests as well as SPSS software (version 11.5) were used to analyze the data. Results showed no significant difference in the task acquisition between the groups while the goal setting group showed significantly better task performance in the immediate and delayed retention tests indicating that goal setting training condition was much more beneficial for volleyball serve learning than no goal setting training condition.

Abstract
The aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (PMA) and the intelligence quotient (IQ) of educable mentally retarded (EMR) children. The sample consisted of 24 EMR girls (mean age = 11.98+1.43 years and IQ = 70.58+ 9.95). Then, they ...

The aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (PMA) and the intelligence quotient (IQ) of educable mentally retarded (EMR) children. The sample consisted of 24 EMR girls (mean age = 11.98+1.43 years and IQ = 70.58+ 9.95). Then, they were matched and assigned to two groups of intervention and control according to their IQ and PMA performance. The intervention group received an 8–week rhythmic motor program three sessions per week, 40–45 minutes per session. The data collection included pretest and posttest of the PMA (Oseretsky scale) and intelligence (Raven’s test) for all subjects. The results showed that the intervention group significantly improved (P>0.05) their PMA after the rhythmic motor program compared with the control group. It was concluded that the PMA of mentally retarded children can be improved with the application of a well-designed rhythmic motor program

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.
