Children in preschool are at an optimal time for the development of gross and fine motor skills. Visual-motor integration is an important perceptual-motor skill that children need to acquire in order to function successfully before formal schooling commences. In this study were investigated the effect of three motor intervention programs (gross, fine, & gross-fine)on visual-motor integration in 80 children who presented below average VMI skills scores. From these participants three experimental (n=60)and a control group (n=20)were randomly selected. The experimental groups participated in a 12 week intervention program of three 45 minutes sessions per week. The Beery-Buktenica developmental test of visual-motor integration 6th edition was used to measure the participants VMI skills. Mixed ANOVA with repeated measures and LSD post hoc test was used to analyze effects of motor intervention programs

The aim of the present study was to study the relationship of motive for health and vitality and enjoyment with the level of adherence of female participants to sport for all (Karaj city). The research method was descriptive-correlation and survey and all women (N=650) participating in sport for all in Karaj city in 2016 formed the statistical population of this study. 243 subjects were selected as the sample according to Morgan table. Hong Yong Lin (2010) international sport participation questionnaire and Scanlan (1993) sport commitment questionnaire were used to collect data after their validity and reliability were determined. The results showed a positive and significant relationship between vitality and enjoyment (correlation coefficient R=0.376) as the first priority and motive for health (correlation coefficient R=0.216) as the second priority and adherence. Therefore, given these findings on the effect of sport for all on vitality, enjoyment and physical and mental health, especially in women as one of the pillars of social health, it is recommended that authorities should pay more attention to the priorities of vitality and enjoyment and provide more facilities for them.

The aim of this study was to investigate national jump roping plan on static and dynamic balance of students. In this study, pretest and posttest were used with two experimental and control groups for male students of fourth grade of elementary school in 2011-2012 in Baharestan city (a region in Robat Karim, Tehran). For this purpose, 60 students were selected from students of fourth grade of elementary schools in Baharestan city using multistage sampling method and were equally divided into two groups. Experimental group implemented the selected jump roping program 3 sessions a week (each session 50 min.) for 10 weeks. K–S test was used to check data normality. Independent and dependent t tests were used to analyze the data (P˂0.05). The results indicated a significant improvement in the experimental group for both static (P=0.019) and dynamic (P=0.005) balance tests. Also, the mean score of dynamic balance posttest was significantly more in the experimental group than control group (P=0.041) but such difference was not observed in the result of static balance test between the two groups (P=0.225). Based on these results, jump roping plan improved the balance of students. So this study considered the jump roping plan to be useful at schools.

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.

The aim of this study was to investigate the effect of selected spark exercises on balance and coordination in autistic children. This study was semi-experimental. 12 autistic children (mean age 5-12 years) participated in this study. The subjects performed the intervention for 3 months based on selected spark exercises. The participants were evaluated in 3 stages (baseline, pretest and posttest) by Bruininks-Oseretsky test in terms of motor skills. Friedman test was used to analyze repeated measures of nonparametric data. The results showed that selected spark exercises significantly improved dynamic balance (P<0.001) and bilateral coordination (P<0.001). It can be generally stated that these selected spark exercises have a positive effect on the improvement of motor deficiencies in autistic children.

The term autistic refers to the individuals who have a set of development disorders relevant to the central nervous system. These children are known to have deficiency in social interaction, language and communication. The aim of this study was to investigate the relationship between motor development and social development of 6-10-year-old autistic children of Mashhad city. The statistical sample involved 41 students with high–functioning autism (31 boys and 10 girls). The researcher calculated the students' social development scores using SCQ questionnaire. Using Lincoln-Oseretsky Motor Development Scale, the level of motor development was determined. In descriptive section, mean and standard deviation were used and in inferential section, Pearson correlation coefficient was applied with 95% confidence level. The results showed a significant relationship between students' motor development and their social development (P<0.05). Also, there was a significant relationship between the boys' gross motor skills, fine motor skills, hand-eye coordination and their social development (P<0.05). The girls' fine motor skills and hand-eye coordination were significantly related to their social development (P<0.05), but there was no significant relationship between the agility of fingers and social development in both groups (P>0.05). These results of the relationship between motor development and social development showed that motor skills can affect the improvement of autistic students.

The aim of the current study was to determine the effect of two types of aerobic exercises on static and dynamic balance of the elderly women. 36 elderly women (60 to 75 years old) were randomly assigned to three groups: 1) walking or jogging (n=12) 2) exercise in water (n=12) 3) control (n=12). Groups 1 and 2 participated in walking (jogging) and exercise in water program for 8 weeks, 3 session per week. The control group had their own daily activities and did not participate in any special kind of sports during this program. Sharpened Romberg and stick balance tests were used to measure the dynamic and static balance. Analysis covariance test (SPSS21) was used to check research hypotheses and to determine the difference among the groups. The results showed significant differences in posttest scores between experimental and control groups (P˂0.05). The results also showed that the group 1 (walking and jogging) gained more scores in dynamic and static balance than the group 2 (exercise in water). It seems that both types of the aerobic exercises especially walking and jogging are appropriate for decreasing the difficulties of this group and can be used as an exercise program in training centers.

Cerebral palsy is a term commonly used for conditions characterized by motor dysfunction due to non-progressive brain damage in early life. The aim of this study was to compare the effects of self-control and experimental-control feedback frequencies on the acquisition, retention and transfer of a throwing task in children with spastic cerebral palsy. From 1750 students with cerebral palsy in Tehran special schools, 30 children (7-12 years old) with spastic hemiplegic cerebral palsy (SHCP) were selected by a convenience sampling method. A pretest consisting of 10 trials was performed to homogenize the participants. Participants were randomly divided into three self-control groups (with 25%, 50% and 75% feedback frequencies) and three experimental-control groups (with 25%, 50% and 75% feedback frequencies) in acquisition, retention, and transfer phases. In the acquisition phase, subjects completed 10 blocks of 8 trials (total of 80 trials). Retention and transfer phases were conducted 24 hours after the acquisition phase. These phases consisted of 10 trials without feedback, except that the subjects performed the transfer phase from 4m distance (vs. 3m distance in acquisition and retention phases). One-way ANOVA test showed no significant difference between the groups receiving the same frequencies (self-control and experimental-control groups) in the acquisition phase while self-control group outperformed in retention and transfer phases. Furthermore, participants who received higher feedback frequencies (self-control or experimental-control group) outperformed those in lower feedback frequencies in all acquisition, retention, and transfer phases. Thus, while the advantages of self-control feedback against experimental-control feedback were observed in the same feedback frequencies, it seems that children use feedbacks in a manner different from adults during motor learning. Thus children may require higher feedback frequencies than adults in order to optimize their motor learning.

The aim of this study was to evaluate the effect of PST on performance, retention, and transfer under pressure of novice badminton players. 40 novice badminton players were randomly assigned to experimental (20 participants) and placebo-control (20 participants) groups. In acquisition and retention tests, short and long service, toss clear and drop shots were used; in transfer under pressure test, notational analysis was applied. All participants acquired specific badminton skills in 24 sessions over three months. In addition to specific badminton skills, the experimental group received the specific package of PST during 24 sessions (each session 20 min.) while placebo-control group received the same number of sessions about general information on badminton. The results of mixed ANOVA indicated that in all tests, the scores of experimental group were significantly higher than those of the placebo-control group, which indicated the effectiveness of PST on performance and learning of novice male badminton players. The results of this study extended the effectiveness of PST to learning new motor skills.

Motor and field characteristic change is called variability of practice that the learner experiences during skill practice. This study was designed to compare the effect of variability of practice on the basketball free-throw learning in implicit and explicit conditions. For this purpose, 40 male (20-27 years old) Shahid Beheshti University students were voluntarily selected and were randomly divided into four groups: implicit learning with variable practice, implicit learning with constant practice, explicit learning with variable practice and explicit learning with constant practice after a pretest. Variable practice groups performed 45 throws from 1.5, 3 and 4 meters distances from the target while constant practice groups had these throws from 3 meters distance each session for 6 days. Implicit learning groups performed a secondary task of counting from 1000 in a reverse order for every triad number along with the free-throw task. But the explicit learning groups performed the free-throw task without a secondary task. The acquisition, retention (48 hours after the last acquisition phase) and transfer (from a 4.6 meters distance) tests were conducted. For data analysis, analysis of variance with repeated measures, two-way ANOVA and Tukey post hoc test were used (P<0.05). The results showed that all groups improved in the acquisition phase (P>0.001) while the main effect of learning and practice was not significant (P>0.05). In addition, in the retention and transfer phases, the main effect of learning type, practice type and the interaction between practice and learning was not significant (P>0.05). Therefore, the results of the present study disagreed with Schmidt's schema theory.

AbstractThe present study was conducted to compare the effectiveness of two different methods to enhance free throw shooting among young basketball players. One method is based on mindfulness(MSPE) and the other is based on mental imagery(MI). This is a semi-experimental study and in terms of data collection, the design of the study is experimental with pre-test, post-test and a control group. Statistical population consisted of young basketball players in Tehran from whom 60 players were selected through convenience sampling and put into the following three groups: mindfulness group, mental imagery group and control group. Statistical analyses were presented in two sections: descriptive statistics and inferential statistics. Descriptive statistics included participants’ characteristics, distribution of data and the variables’ mean and standard deviation. Shapiro-Wilk test was also used to determine whether the data were naturally occurring. Then, the data were analyzed through inferential statistics using paired-samples T-Test, ANOVA, Leven’s Test, Games-Howell Test and Bonferroni post hoc Test to test the hypotheses. Significance level of the study was set at 0.05. The results obtained from the pre-test and post-test of both mindfulness and mental imagery groups showed the participants’ performance was significant with mean differences of 4.15 and -2.55 respectively. Also, the final findings of the study indicated that treatment in mindfulness group was more effective than that of mental imagery group, in improving free throw shooting (P=0.2).Key words: basketball, Free throw, Mindfulness, Mental imagery, Sport performance

The aim of the present study was to investigate the manipulation of senses and speed on the performance of bimanual dynamic coordination. Thus, 15 physical education students of Shahid Beheshti University with age range of 18-25 years performed in-phase and anti-phase patterns from slow to fast speed in five different sensory conditions. To investigate two motor patterns ANOVA with repeated measures (5 sensory conditions × 3 speeds) on each in-phase and anti-phase pattern. Bonferroni post hoc test was used to analyze their following effects. The dependent variable was error of relative phase. Results showed that increasing the speed of performance influenced the performance of the anti-phase pattern (P=0.001), but it did not influence the in-phase pattern (P=0.9). Sensory manipulation results indicated that proprioception and vision manipulation had an effect on the accuracy and the variability of performance of two relative phases of motor patterns (P=0.001), but audition manipulation did not affect these patterns (P=0.315). In addition, the highest mean of error of relative phase and standard deviation of error of relative phase were observed in proprioception manipulation (P=0.001). It can be expressed that the bimanual linear coordination task in this study was a proprioceptive dependent task.

The aim of this study was to determine the effect of social-comparative feedback on acquisition and consolidation of a perceptual-motor skill in high school male students. In this study, 36 high school students as the sample were randomly assigned to three groups (each group 12 subjects): positive, negative and veridical social-comparative feedback. Pretest scores were recorded. Acquisition phase lasted five days and each subjects daily performed 10 blocks of 3 trials of badminton long serve. After each block, they received the feedback of their mean scores in the form of positive (higher than the actual score), negative (lower than the actual score) and veridical (the actual score) given the group to which they belonged. After 72 hours of detraining, consolidation test was performed under the same conditions as the pretest. After determining the data normality and homogeneity of variances, ANOVA with repeated measures, one-way ANOVA and Tukey post hoc test were used to analyze data at the significance level of P≤0.05. The results showed that training improved the performance of groups in the acquisition phase. But there was no significant difference in the performance of the groups. The consolidation of positive feedback group was significantly better than the other groups. These findings suggest that positive social-comparative feedback affects the consolidation of a perceptual-motor skill such as targeted badminton long serve skill.

The aim of this research was to investigate the ability of arousal control in male and female athletes using mental imagery and biofeedback methods. Participants were 30 male and female athlete students of Tehran University (mean aged 23) who were assigned into two homogeneous groups based on Vividness of Movement Imagery Questionnaire 2. Participants were given acoustic biofeedback during three stages of pretest, posttest, and follow-up test while their scores in arousal indexes such as heart rate, body temperature, and galvanic skin response were recorded. In posttest, they were asked to mentally imagine their performance under competition circumstance and in follow-up test they had to attempt to lower their arousal level using deep breathing and acoustic biofeedback technique. Results of analysis of variance with repeated measures and independent t test indicated that there is a significant difference between groups mean scores in follow-up test in three indexes of heart rate, body temperature, and galvanic skin response (p≤0/05). This finding suggests that male students have higher ability in arousal control compared with female students.

Boxing is one of the organized high-contact sports that requires purposefulpunches to the head and body of the opponent in both amateur and professionallevels, so traumatic head injury in boxers isn’t impossible. In this type of injury,though intact cognitive functions, it is possible that total cognitive beneficiarybecome impaired as a result of distractibility, imperfect concentration, andaftermath fatigue. Thus, purpose of this study was to investigate attentionaldisorders in amateur boxing. Subjects of the study were 30 male experiencedamateur boxers (more than 4 years background, age= 24±3.1) as experimentalgroup, and 30 male novice amateur boxers (less than 1 year background,age=25±4.2) and 30 male 400 and 800 meter runners (age= 24±2.7) as controlgroups. We used DAUF continuous attention test to assess attentional component.In order to data analyzing was used MANOVA in the significance level of 0.05.Findings showed that in none of variables there were significant differencebetween groups (P>0.05), meaning that amateur boxing periods even longer than4 years doesn't lead to attentional disorders. Based on our findings, it is concludedthat intensity of punches in amateur boxing doesn't reach to threshold that lead tobrain damage at least in regions which control visual attention.

Aim: The use of psychological interventions in sport to enhance performance has become increasingly popular. However, the effectiveness of these interventions has been questioned by some sports psychologists. Educationally-based psychological interventions have produced significant increases in performance. It was found that 38 of the 45 studies examined (85%) had found positive performance effects, although causality could only be inferred in 20 of these studies. These interventions could be classified as relaxation-based, cognitive, cognitive-behavioural or behavioural in nature. The purpose of this study was to evaluate the effect of physical practice, mental imagery and music on the improvement of basketball shooting skill.Methodology: In this quasi-experiment study, 45 students (19-22 years) were randomly selected from elementary schools and classified in the three experimental groups consisting 15 participants. Physical practice, mental imagery and imagery along with music were the order of three experimental groups. The data was collected using modified basketball shooting in this study.Results: Statistical analysis was conducted with the descriptive statistics tests consisting kolmogro-smirnow, T test and one way-anova. The result of present study indicated significant differences (p< 0.05) between pre and posttest of physical practice, physical practice with mental imagery and physical practice with mental imagery and music.Conclusion: Based on inter group comparison, it can be said that mixed method was more efficient than other two methods and significant difference was not reported between physical practice with mental imagery and physical practice. Thus, it is suggested that different teaching methods should be used for promoting training programs.

The aim of this study was to investigate the effect of different sport fields, different training levels and their interactive effects on indicators of growth and sexual maturation of adolescent female athletes. The population consisted of all adolescent female athletes (aged 17-9) in gymnastics, volleyball and table tennis in Arak city and the sample included 49 gymnasts, 82 volleyball players and 38 table tennis players who were selected by multistage cluster sampling method. The data were collected by a demographic questionnaire, the physical activity questionnaire for adolescent (PAQ-A), the Tanner Table and bioelectric resistance method. To analyze the data, covariance analysis at (P≤0.05) was used. The findings showed that different sport fields had significant effects on indicators of height, leg length and fat (P˂0.05). Different training levels had significant effects on indicators of fat (P≤0.05). The interactive effect of different sport fields and different training levels had no significant effects on indicators of growth and sexual maturation (P≥0.05). It was concluded that athletes enter these three sport fields when their growth characteristics are proportional to the needs of that field. Also, maximum 10 hours of exercise training per week have no adverse effects on indicators of growth and sexual maturation of athletes.

The purpose of this research was to investigate the effect of physical exercise and addiction of female rats on male offspring's physical growth indexes. The research method was experimental. Statistical population consisted of female rats (albino – wistar) obtained from Pasteur Institute, Iran. The data were gathered from 116 male offspring (including 4 groups: addicted mother– sporting mother – addictive sporting mother and intact group) and 80 mothers (to estimate the length of pregnancy). The drug used in this study was manufactured by Daroopakhsh factory. The findings from physical growth indexes (height, weight, head circumference and gestational days) suggested that addiction (before pregnancy) played an effective role in physical growth indexes within the first 5 days which can be due to the increased pregnancy period (P

The aim of this research was to examine the effects of PETTLEP-based imagery compared to more traditional imagery on learning badminton short service (backhand). For this purpose, 45 male students (age 12-14 years) were non-randomly selected and divided into three groups of 15 students each (they were beginners). The groups exercised in the following way: first group performed PETTLEP-based imagery and practical training. Participants in the PETTLEP imagery group applied the physical principles of PETTLEP imagery training. They were requested to imagine performing badminton short service wearing their complete badminton competition uniform; second group performed traditional techniques of imagery and practical training. Participants in the traditional imagery group engaged in a relaxation session before imagery; third group performed practical training. In 7th, 14th, 21st and 28th session, all subjects performed French test. The obtained data were analyzed by ANOVA and Tokey tests. The results showed a significant difference between PETTLEP-based imagery and traditional technique of imagery groups in learning badminton short service technique. There was a significant difference between traditional technique of imagery group and control group in learning badminton short service technique. In retention test, there was a significant difference between PETTLEP-based imagery with traditional technique of imagery and control group in learning badminton short service technique. It is suggested that coaches and physical educators use PETTLEP when possible.
