Introduction: In recent years, there has been considerable interest in the evolution of physical education teaching from a linear to a non-linear approach. This study aimed to investigate the effectiveness of traditional games with a hybrid of games for understanding and game sense teaching approaches on students' motor proficiency.Methods: This research was quasi-experimental with a pre-test and post-test design conducted in a field-based study. Fifty-five girl students (10-11years) were randomly divided into four groups: teaching game for understanding, game sense, hybrid of teaching game for understanding and game sense, and traditional group. Subjects practiced one-hour session three days a week according to their group's educational approach for 12 weeks. The Bruininks-Oseretsky test was used to assess children's motor proficiency.Results: The results of Mixed ANOVA showed a significant difference between the pre-test and post-test of the first three groups. So, it can be stated that for gross motor skills, the Hybrid group got the highest score with 79% of variance explained, and for fine motor skills and total motor proficiency, the teaching game for understanding got the highest scores with 84% and 85% of the variance explained, respectively. Traditional education did not have a significant effect on the investigated variables.Conclusion: It can be concluded that using the hybrid approach improves children's motor proficiency. The present study shows that teaching games for understanding and game sense models in the form of traditional games are a proper training method to improve motor proficiency in students. It seems that these approaches can be transferred to other educational levels

Balance is one of the basic important principles of learning in children, and its disorder can negatively affect learning.The aim of this study was to investigate the effect of selected motor games on balance in children with specific learning disorder. This study was semi-experimental and application in terms of aims with pretest-posttest and a control group. 24 boys (7-9 years old) with specific learning disorder in Mashhad city were selected and assigned randomly to experimental and control groups. The experimental group performed selected motor games for 20 sessions, 30 minutes each sessions, 5 sessions per week. During this period, the control group performed its routine activities. Changes in the static balance of the subjects were measured by the Stork balance test and Sharpened Romberg test and dynamic balance of the subjects were measured by the heel-to-toe walk test and timed up-and-go test before and after the intervention. For statistical analysis, analysis of variance with repeated measures was used. Findings showed that selected motor games improved the static and dynamic balance of the experimental group. All these changes were significant in comparison with the control group (P<0.05). Based on these findings, it can be concluded that selected motor games help to improve static and dynamic balance in children with specific learning disorder.

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.

Contextual interference is one of the instructional methods for several skills.The aim of this research was to determine the effects of interference beforeperformance and interference during performance on the acquisition and retentionof generalized motor program and parameter in basketball skills with an emphasison the examination of contextual interference hypotheses and self-regulationlearning theories. In interference before performance, self-practice schedules isgenerated (self-regulation effect) and interference during performance,experimenter-imposed practice schedule is generated (contextual interferenceeffect). For this purpose, 120 students of Yazd University (age range 19-21 yearsold) who had no prior experience in basketball skills volunteered to participate inthis study. Participants were randomly assigned to 10 groups (each 12 subjects); 5groups practiced with generalized motor program (dribble, chest pass and freethrow skills) and 5 groups practiced with parameter (free throw from differentdistances) in practice schedules (blocked, random, serial, self-regulated and yokedto self-regulated). To collect data, throw and pass test (AAHPERD basketball test)and dribble test (Johnson basketball test) were used. After the pretest, in theacquisition phase, subjects took part in 5 training sessions including 45 trails persession (15 trails each block) for 5 days. After 48 hours, they participated inretention test with 15 trails (5 trials each task). The data were analyzed by one-way ANOVA, factor analysis of variance with repeated measures, LSD and Duncanpost hoc tests. Results showed a significant difference among practice schedules inacquisition and retention phases of generalized motor program, that is, the effect ofcontextual interference was observed in this program (p<0.05). Also, there was asignificant difference among the schedules in acquisition and retention phases ofparameter, that is, controlling the design of practice has a positive effect onlearning (p<0.05). Thus, the results suggested that during learning process, theeffect of interference before performance was more important than duringperformance.

It is possible that society and media attention to national athletes increase their narcissism. Based on this possibility, this study which was descriptive and field aimed at comparing narcissism between elite and non-elite athlete students and non-athlete students. The population consisted of students of physical education and sport sciences faculties of Tehran universities. 105 athlete students at national and regional levels from team sports (football, volleyball and basketball) (n=35) and individual sports (wrestling, Judo and track and field) (n=35) and non-athlete students (n=35) were selected by availability method as the sample of the study. Data were gathered by Narcissistic Personality Inventory (Raskin and Terry) and Eysenck personality questionnaire (EPQ) and analyzed by ANOVA and Newman-Keuls post hoc test. The results showed no significant difference between national athlete students and regional athlete students and non-athlete students in narcissism, nervousism and psychosism (P≤0.05). But national athletes gained higher scores in extroversion compared with regional athlete students and non-athlete students (P≤0.05).

Reflexes are body automatic and involuntary responses to a variety of stimuli such as pressure, sound and tactile stimulation which are used as means to determine the level of neurological maturation and to diagnose central nervous system disorders. The aim of this study was to investigate the effect of mothers’ tactile kinetic stimulations on reflex state of preterm neonates. For this purpose, 40 infants and mothers were purposively selected from infants hospitalized in neonatal ward of Amiralmomenin hospital in Semnan city during one to two months and were randomly divided into experimental and control groups. Then, mothers of experimental group conducted tactile kinetic stimulations on their infants until the completion of fetal period (40 weeks of gestation) 3 times a day, 20 minutes each time whereas the control group received only the usual care. Neonatal Behavioral Assessment Scale was used to evaluate reflex state of neonates before and after the intervention. The results of mixed ANOVA showed that although reflexes of premature neonates in the experimental group improved more than the control group, this increase was not significant (P≥0.05). However, given these results, it can be said that tactile kinetic stimulations can be a solution to improve the reflex state of preterm neonates and more time frame is probably required to reveal the beneficial effects of intervention.

Feedback is one of the most important variables that affects the performance of motor learning and the way of implementing skills and has an important role in motor control and motor skill acquisition. This study aimed at evaluating the acquisition and retention of new skills in children with autism in augmented feedbacks with various frequencies. Study method was semi-experimental and study design was pretest–posttest. The retention test was carried out with three feedback groups (0%, 50% and 100%). The study population consisted of 6-8-year-old male children with autism in Ahvaz city. 21 subjects were selected through available and purposive sampling method as the sample of the study and were randomly divided into three groups. The subjects' task was to throw a tennis ball over their shoulders towards a target drawn on the ground. In the acquisition phase, subjects threw 60 tennis balls. Group 0% did not receive any feedback, group 50% received feedback in half of their efforts and group 100% received feedback in all their efforts. 24 hours after the acquisition phase, retention test was performed in 10 trials. After checking the data normality and variance equality, data were analyzed by analysis of variance with repeated measures, ANOVA and Tukey post hoc test. The results showed a significant difference in the acquisition and retention stages among the three groups (P=0.001). Group 100% outperformed both in the acquisition and retention phases. It is generally suggested that in the skill learning process, children with autism benefit from augmented feedback with high frequency.

This study aimed at investigating the effect of sleep deprivation and retroactive interference on offline learning in tennis simulated game. Based on the questionnaires related to the variables under study, 50 female students of Semnan University (age range 19-25 years) were selected as the sample and divided into 5 groups: perfect sleep, sleep deprivation, perfect sleep and retroactive interference, sleep deprivation and retroactive intervention and training with rest interval less than 1 hour. A tennis simulated game (with rules and scoring similar to a real game) was performed to measure offline learning. One-way ANOVA and ANOVA with repeated measures were used for inferential statistics at a significance level (P≤0.05). The results showed that the differences in offline learning (Sig=0.001) and retention scores (Sig=0.001) were significant among the research groups. In those groups with sufficient rest intervals between each two sessions and full rest, the level of their performance was higher in the next day than the previous day. Opposite effects were observed with sleep deprivation and retroactive interference. Therefore, those who are learning a skill should pay attention to their daily activities and sleep patterns to prevent a disruption to skill learning and to take advantage of their practices.

The concept of imagery is to make an image of successful movement skill or a
relaxing image in mind with no body training and external experience. The aim of
the present study was to compare the effect of traditional and PETTLEP mental
imagery methods on static and dynamic balance. The statistical population
consisted of all female University of Tehran students who had general physical
education course (1) in the first educational semester in 1389-1390. 54
participants (Mean age 21.94±1.89 yrs) attended voluntary in this study. First, they
completed the Revised Movement Imagery Questionnaire (MIQ-R: Hall & Martin,
1997). Afterwards, pretest of static balance (Stork Balance Test) and dynamic
balance (Modified Bass Test of Dynamic Balance) were performed. Participants
were randomly assigned to three (n=18) groups (Physical training, Traditional
imagery and PETTLEP imagery) and trained for 12 weeks (20 min/week). Finally,
posttests of static and dynamic balance were performed under the same condition
as the pretest. Retention test was performed 24 hours later and transfer test 30
minutes after the retention test. One-way ANOVA test showed no significant
difference in static balance, dynamic balance and imagery ability scores in pretest
among groups (p>0.05). Although ANOVA with repeated measures illustrated that
although all three groups improved significantly in static and dynamic balance
(P0.05).
Overall, results showed PETTLEP imagery was an effective method but not
sufficiently efficient in dynamic balance.

In most people getting old is associated with a decrease in both cognitive and motor functions. One of these functions that get affected is reaction time. The aim of this study was to investigate the effect of neurofeedback training protocol variation on the reaction time of elderly people, Which is based on the principle of specificity of training. For this purpose ,Forty elderly participants between the ages of 65 to 70 years were selected and assigned to one of the for groups of experimental groups: 1) neurofeedback at Cz and beta wave, fixed frequency, fixed training arrangement, 2) neurofeedback at Cz and beta wave, fixed frequency, variable training arrangement 3) Neurofeedback at Cz and beta wave, variable frequency, fixed training arrangement, 4) Neurofeedback at Cz and beta wave, variable frequency, variable training arrangement) and 5) control (sham). All groups participated in simple reaction time tests for pre-test and post-test. The analysis of covariance showed that neurofeedback interventions had a significant effect on the reaction time of elderly people (p <0.05) and the frequency and the group with variable training arrangement had the best performance compared to the other groups (p <0.05). According to these results neurofeedback, training affects improving the reaction time of the elderly people and these interventions should be designed based on the principle of specificity of training.

It is important for people to improve cognitive and motor performance. The purpouse of this study was to investigate the effect of running on treadmill in spatial memory and learning and motor performance. 24 Albino-Wistar healthy male rats were randomly divided into control and activity groups. Activity group ran 7 days on treadmill (speed 22m/min 30 minutes a day). After the end of activity period, Morris Water Maze and open-field tests were done to respectively assess spatial learning and motor performance. It was used latency time, and distance moved to find platform to assess spatial learning, and distance moved, mobility duration, and movement speed to assess motor activity. It was used SEM±M and analyze variance (2groups*3days) and independent-t tests to analyze data.Results indicated that In spatial learning, activity group was significantly better in acquisition (distance moved F2,44=6/578 p=0/003 and latency time F2,44=10/550, p=0/000 ), probe (time spend in target quarter t22=2/534 , p=0/019), and retrieval tests (distance moved t22=2/651, p-0/015) than control group. In motor activity there was no significant difference between two groups.The results of this study show that the forced running of rats on treadmill for a week can improve learning and memory.

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.

The aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. For this purpose, 45 old subjects agedbetween 60 and 70 from Qom province participated in this study. Static balancetask (stand on one leg) and dynamic balance task (SEBT test) were instructed withno self–talk intervention. Then, they were divided into three groups: motivationalself–talk, instructional self–talk and control. One–way analysis of variance andTukey post hoc test were used to analyze the data. The results showed a significantdifference among the groups. The result of Tukey post hoc test showed nosignificant difference in static balance task between instructional and motivationalself–talk (P>0.05). Also, in dynamic balance task, instructional self–talksignificantly improved balance function compared to motivational self–talk(P<0.05). Generally, self–talk as a cognitive strategy was effective in performingbalance tasks and motivational self–talk was preferred in dynamic balance tasks.

The aim of this study was to determine the interactional effects of various video
shows (skilled and self-model) and feedback type on performance and learning of
dart throwing skill. 90 volunteers were randomly divided into 6 groups including
self-control, experimenter control and yoked feedback that received either skilled
model or self-model. Three groups who watched the skilled model observed dart
throwing by a member of dart national team at first and at rest intervals whereas
self-model groups watched their own performance as a recorded movie. Selfcontrol
groups requested feedback from the examiner during their performance.
Yoked groups received feedback in those attempts on which self-control groups
requested feedback and experimenter-control groups received feedback by
examiner. Subjects trained for six days and then participated in the retention (after
48 hours) and transfer (immediately after retention) tests. The method of the study
was semi-experimental and data were analyzed using analysis of variance with
repeated measures, two-way analysis of variance and Bonferroni and Tukey post
hoc tests. Results showed that all six groups improved from pretest to acquisition,
retention and transfer. Regardless of the role of feedback, there was no difference
between skilled and self-model in any stages. Experimenter control feedback had
more efficiency than other feedbacks in the acquisition while self-control feedback
was better in retention and transfer. Furthermore, results showed that those
subjects who received self-control feedback had more learning when they observed
self-model. The main reason why self-model-self-control feedback group was better
than other groups could be the effect of motivational processes resulted from this
interaction and more coordination of this feedback with subjects’ demands.

In this study, the effect of cognitive load (CL) training on duration and accuracy of bimanual coordination (BC) task was investigated. For this purpose, athletic male students of Shiraz University were randomly divided into 4 groups: G1 with low CL, G2 with intermediate CL, G3 with high CL and G4 control. The subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. The subjects performed bimanual coordination task by Vienna test system (v=71%-84% and r=85%-96%). Independent T test and one-way ANOVA were used to analyze the data. The results showed that high CL affected the accuracy of bimanual coordination task. No significant difference was observed between CL groups and control group in overall duration (?=0.05). It can be concluded that if there is high CL in activities which require much attention, attention capacity may change and in skills that need attention, the task can be improved after information processing as a result of capacity change.

The main aim of this study was to investigate the effect of cognitive empowerment on working memory and observational learning of dart throwing skill in children. 40 students aged between 10 and 11 were selected by convenience sampling method. In the first phase, cognitive empowerment was performed and in the second phase observational learning of dart throwing skill was performed. In the first phase, the cognitive pretest was performed and the subjects were divided into two homogenies groups (each group 20 subjects): cognitive practice and no cognitive practice based on their age and pretest scores. The cognitive group received 8 sessions (45 minutes per session) of cognitive empowerment practice. Then, both groups received cognitive posttest. The cognitive tests were performed using Corsiblack (working memory) software. In the second phase of the study, each of the first phase groups were divided into 2 groups (10 subjects each group): observational + physical and physical. After dart throwing pretest, dart throwing was practiced in the form of observational and physical (3 sections of 20 throwing). The observational + physical group watched the skilled model of dart throwing through video in addition to dart throwing. Then, posttest was performed at the end of the second phase. Analysis of variance with repeated measures of 2 * 3 and 4 * 2 was used. The results showed that the working memory of cognitive group was significantly better than non-cognitive group. The cognitive + observational + physical group performed significantly better in the dart posttest than the other groups. It seems that cognitive empowerment can facilitate learning trough observation.

The aim of this study was to evaluate the effectiveness of transcranial direct current stimulation (tDCS) on working memory in children with developmental coordination disorder (DCD). The research method was quasi-experimental with pretest and posttest and retention with experimental and control groups. The research population consisted of children (age: 7-11 years old) in Urmia city in 2018. 16 children with DCD were selected as the sample with convenience sampling method and based on inclusion and exclusion criteria, and then were randomly divided into two groups: experimental (n=8) and control (n=8). The experimental group received 10 sessions (each session 10 minutes) of tDCS on f4 and f3 brain zones with 0.75 mA circuitry. The control group received 10 sessions of sham circuitry for 20 seconds, then the circuity was cut off, but they were not informed of this sham circuity. The data of working memory were collected using N-BACK test. The analysis of variance with repeated measurements was used to test the research hypothesis (P=0.05). The results showed that transcranial direct current stimulation (tDCS) had a significant effect on the enhancement of working memory and the effect would continue to the retention phase (P=0.05). This approach can be used to improve working memory in children with DCD.

The aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). The training protocol was performed three sessions a week for 6 weeks. Data analysis indicated a significant difference between the groups in acquisition (P=0.001) and retention (P=0.002) phases. The results of Tukey post hoc test in the acquisition phase indicated no significant differences between cognitive specific imagery group and cognitive general imagery group (P=0.53) but there were significant differences between cognitive specific imagery group and traditional imagery group (P=0.006) and also between cognitive general imagery group and traditional imagery group (P=0.03). Also, in the retention phase, the results of Tukey post hoc test indicated significant differences between cognitive specific mental imagery group and traditional mental imagery group (P=0.002), between cognitive specific mental imagery group and cognitive general mental imagery group (P=0.037) and between cognitive general imagery group and traditional imagery group (P=0.001). With regard to the findings, the role of the cognitive specific imagery was in the center of attention more than before and soccer instructors and coaches are recommended to use this type of imagery.

The aim of this study was to examine the effect of overt and covert motivationalself-talk on perceived exertion and performance in a progressive exercise untilexhaustion in wrestlers. The population consisted of wrestlers in Urmia and 15volunteer subjects were selected. This study was performed in three sessions with aone-week interval. The first session was held without self–talk while the second andthird sessions were held covertly and overtly respectively. Bruce aerobic exercisetest was used in this study as well. The time to exhaustion was considered asperformance. Burg scale was used every 3 minutes in order to measure subjects'exhaustion. To analyze the data, ANOVA with repeated measures and TUKEY posthoc test was used. The results showed that only covert self-talk had a significanteffect on subjects’ performance (P=0.002). Also, overt motivational self-talk(P=0.001) significantly decreased the subjects' perceived exertion rather thancovert self–talk. There was no significant difference between covert self-talk andwithout self–talk (P=0.121). In conclusion, overt motivational self-talk decreasedthe perceived exertion of the subjects in the progressive exercise until exhaustionwhile covert motivational self-talk improved subjects’ endurance.

Attention deficit/hyperactivity disorder (ADHD), is one of the common neurodevelopmental disorders in children, can produce several cognitive, social and educational difficulties. The purpose of this study is to investigate the effect of fundamental motor skills (FMS) on cognitive impulsivity, motor impulsivity and sustained attention in primary school children with attention deficit/hyperactivity disorder symptoms. The research method was quasi-experimental with pre-test-post-test design. The study population consists of all elementary school students of Shiraz schools. The sample used for the study was 38 students with ADHD symptoms which was selected by multi-level sampling based on SNAP-IV and randomly divided in two groups, experiment (21 subjects) and control (17 subjects). The experimental group trained for ten sessions in the FMS program and the control group dealt its daily activities. Then one session before and after of interventions all of the two groups were measured with using of continuous performance, dexterity, porteus maze and passing test. Data were analyzed by mixed repeated measures ANOVA and indicate that FMS training can have a positive effect on children performance in motor impulsivity, but there was no evidence of the effect of mentioned interventions on Cognitive impulsivity and sustained attention. According to the findings of the study, can be concluded that short term FMS training can be useful in controlling movement and impulses in children with ADHD symptoms.

During recent years, mindfulness interventions have shown significant effects on athletic performance; however, researches on the effectiveness of these interventions on important psychological characteristics such as motivation and burnout of athletes are limited. The aim of this study was to investigate the effect of sports mindfulness intervention (MPSE) on motivation and burnout in athletes. For this purpose, 40 athletic students of Chabahar University were selected as the sample by convenience sampling method and were divided into intervention and control groups. Exercise Motivation Questionnaire (SMS-6) and Sports Burnout Questionnaire (ABQ) were used to collect data. 6 weeks of sport mindfulness intervention were used for athletes. Questionnaires were distributed among athletes before and after the intervention and data from questionnaires were analyzed by SPSS software version 20 by means of descriptive and inferential statistics (analysis of covariance). The results showed that sport mindfulness intervention significantly decreased the burnout (P>0.05). These interventions also significantly increased intrinsic motivation and significantly decreased demotivation and extrinsic motivation of athletes (P<0.05). These results suggested that sport mindfulness interventions can be used as an appropriate instrument to increase the autonomy of sport motivation and to reduce the harmful effects of sport burnout.
