The apparatus of the study was Xbox device. Sharpend Rumberg Test was used to assess the static balance scores. Experimental group performed their practice in the virtual environment during 4 weeks, 3 days per week, and 1 hour per day. Control group continued their common occupational therapy programs. MANCOVA and ANCOVA Tests were used at p

Abstract Recognition of important psychological factors in coping with difficulty is considered as an important factor in the development of positive interventions to achieve sports self-fulfillment. Self-sufficiency and cognitive regulation of emotion are important factors that are effective in coping with unpleasant events. In a difficult event such as failure in sports is not considered. Therefore The purpose of this study was to model the structural equation of relationship between self -compassion and emotional reactions to failure as mediated by cognitive emotion regulation among martial arts. A total of 286 athlete (191 men and 95 women; age: 20.98±3.30 years) from different disciplines of martial arts (taekwondo, karate, Judo and wushu) engaged in league championship participated in the study. Athlete completed self-report measures of self-compassion (SCS), negative affect (PANAS), and cognitive emotion regulation (CERQ). The proposed model was evaluated using structural equation model. Result revealed that self-compassion has direct and indirect effects on emotional reactions to failure. Furthermore, cognitive emotion regulation a partial negative mediator between the self-compassion and emotional reactions to failure. This study indicates that self-compassion is a relevant construct for understanding athletes’emotional responses to failure problems and cognitive emotion regulation strategies are involved as underlying mechanisms in this process. Therefore, it suggests paying attention to growth of self-compassion in martial arts and emphasizing on improving adaptive emotion regulation and reducing incompatible emotion regulation in order to recover better from failure and reduce its negative effects.

Abstract The aim of this study was to compare the effective of active video games and sports basic games on the development of fundamental motor skills in elementary school students. The method of the present study is semi-experimental with pretest-posttest design with control group. Sixty male students (age range: 8-11 years old) were selected by convenience sampling and randomly divided into two experimental groups (active video games (XbX), sports basic games) and a control group (inactive video games). The instruments used in this study are the Brunnicks-Ozertsky motor proficiency test, second edition, and the XbX 360 Kinect. First, participants performed motor skills pretest. Experimental groups performed the relevant training program for eight weeks, twice a week and 30 minutes per session. The control group also played passive video games under the full supervision of the Examiner with XbX console. At the end of the training sessions, the second edition of the Bruins Ozertsky motor proficiency test was repeated for all subjects (post-test phase). The results of the present study showed that active video and sports basic groups have a significant effect on the development of basic motor skills. Other results of this study showed that there is a significant difference between groups in the development of fundamental motor skills; these differences were significant with the traditional group, but significant differences were not found between the experimental groups. Therefore, it is recommended that coaches, in addition to sport basic trainings, they should also pay special attention to active video games.

Abstract Behavioral and emotional problems are one of the most common psychological problems in childhood and adolescence. Evidence suggests that behavioral problems are more prevalent among intellectual disability children than normal children. Therefore, the present study aimed to determine the effectiveness of a parent-centered intervention based on localized play therapy on behavioral problems of 5-7 years old intellectual disability children. This study was experimental with pretest-posttest design and follow-up with control group. The statistical population consisted of 128 educable intellectual disability children who were educated in special centers in Lordegan in 1397. Thirty people were selected randomly and assigned to two groups of 15 (experimental and control). Rutter Behavioral Problems Questionnaire was administered to two groups as pre-test. Then, the experimental group's parents received a 12-session localized game therapy intervention and the parents of the control group did not receive the intervention. At the end of the intervention period and 3 months later, Rutter's Behavioral Problems Test was again administered to the two groups as posttest and follow up, respectively. Data were analyzed using ANOVA with repeated measures. Results showed that there was a statistically significant difference between the performance of the two experimental and control groups in the rate of behavioral problems (p <0.001). Therefore, it can be concluded that the localized play therapy intervention program has been effective in reducing the behavioral problems of intellectual disability children and the survival of the intervention program remained after 3 month.

Abstract The purpose of current study was to muscle efficiency changes during successful and unsuccessful trials in elite pistol shooters with role of quiet eye meditation. In causal comparative study, 20 elite male pistol shooters selected for this study with age range 20-30 years old. After five trials familiarization, participants performed 20 trials to target with available standard. Scores of ten were considered successful, and scores of less than ten were considered unsuccessful. Data were analyzed using paired t-test and Bootstrap. The results indicated that there was significant difference between biceps and triceps muscle activity in successful and unsuccessful trials, and participants had lower muscle activity in successful trials than unsuccessful trials. Also, Bootstrap results revealed that the quiet eye period mediates biceps and triceps muscle activity in successful and unsuccessful trials. Overall, the results of current study confirmed postural stability hypothesis that this is the determining factor during this period is an increase in postural stability, which leads to a reduction in "noise" in the motor system.Shooting skills with high perceptual / cognitive requirements and low mobility needs and is one of the sports that is highly dependent on the performance of the visual system, because target identification and tracking is largely dependent on the performance of the visual system.In the present study, the researcher intends to investigate the muscular efficiency and mediating role of the length of the stationary eye period in the electrical activity of biceps and triceps of skilled pistol shooters in successful and unsuccessful attempts.

Abstract Introduction: Children with learning disorder have more inefficient use of gaze strategies in various tasks.
Purpose: The purpose of this study was to examine the effect of quiet eye training on muscle activity and targeting-interceptive skill accuracy in children with learning disorder.
Methods: In this semi- experimental study with a repeated-measure design, 30 boys aged 7-10 years with learning disorder were divided into quiet eye and control groups . In the pre-test phase, participants performed 10 trails to throw and catch task the ball. Acquisition phase have done in eight weeks and three sessions in per weeks. In per session after the video-gaze exercises, 10 trials were performed to throw and catch task in accordance with the gaze exercises instructions. At the end of the last training session, in the post-test phase, in two weeks of detraining in the retention and transfer phases, the participants performed 10 trials to throw and catch task the ball. At each phase, the selected muscle electrical activity was recorded by electromyography and the throw and catch task performance was recorded by the researcher. Data were analyzed by analysis of variance with repeated measures with 0.05 significant levels.
Results: The results indicated that quiet eye training have a significant effect on increasing the learning of targeting-interceptive skills and on reducing the muscles electrical activity.
Conclusion: The results of this study support the pre-programming hypothesis on the importance of planning and choosing the correct answer.

Abstract The aim of this study was to investigate the effect of fine motor skills on stereotyped movements of children with autism aged 7 to 15 years in Khomein in 1399. In this quasi-experimental study, 20 children with autism were selected by available sampling method from Khomein Sustained Autism Rehabilitation Center. Then the subjects were randomly divided into two control groups (n = 10) with mean age (10 ± 16/3) and mean height (118 ± 42/23) and mean weight (42 ± 16/7) and experimental group (n = 10) With mean age (12 ± 79/2) and mean height (116 ± 67/34) and mean weight (38 ± 34/8). The experimental group received 15 sessions of 40 minutes (three sessions per week) of fine motor skills training, and the control group performed their daily activities during this period. The Gilliam (Garz) autism test was used to assess stereotyped movements. Data analysis was performed by Leven, Kolmogorov-Smirnov test and multivariate variance at the significant level of P

Abstract The aim of this study was to investigate the role of mediators of resilience and perceived social support in the relationship between physical activity and psychological distress during the Covid-19 virus outbreak. The research method was correlation and the statistical population included Iranian adults (18-64 years) that 1115 male and female were selected as a sample from the people of Tehran and 10 other provinces from 5 geographical regions by random sampling. The International Physical Activity questionnaire, the Kessler Psychological Distress Scale, the Connor-Davidson Resilience Scale, and Perceived Social Support was used for data collection. Using Spearman correlation coefficient, the relationships between research variables were calculated using SPSS25 software. Structural Equation Modeling (SEM) was also used to test the hypothetical model of direct and indirect relationships between physical activity, psychological distress, resilience, and perceived social support using PLS3 software. The results of modeling the structural equations indicated a good fit of the model. Findings showed a significant inverse relationship between physical activity and psychological distress (β = -0.314; P≤ 00 0.001) and indirect pathway coefficient of physical activity and psychological distress mediated by perceived social support (β = -0.35; P≤0.001) and resilience (β =-0.057; P≤0.001) were significant. It is suggested that in order to reduce psychological distress in the period of Covid-19 virus outbreak, feasible physical activity programs be used simultaneously with perceived social support and resilience intervention.
