Introduction: One of the most complex processes in the field of sports expertise is decision-making. In this respect, this study aimed to investigate the effect of decision training on anticipation and creative decision-making in badminton.Methods: The current research is a quasi-experimental type with a pre-test and post-test design. The statistical population of the present study was all female students aged 20 to 30 years, from which 40 female students were selected by the available sampling method and randomly assigned into two decision training and control groups. A creative decision-making questionnaire, video camera, laptop, and projector were the tools used in the research. In the pretest, creative decision-making and anticipation were measured with 20 video clips while watching a badminton overhead shot through a video clip that was interrupted at the moment of racket-ball contact. The training group practiced 400 decision training trials and the control group just recognized the direction of the shots. A post-test was taken after 48 hours.Results: The result revealed that in the post-test, the decision training group had more creativity in decision-making than the control group (F=2.64) and in the training group, the skill of anticipating the direction of the shots was better than the control group (F=4.17).Conclusion: According to the results, the decision training made the players of the training group recognize the direction and landing place of the shot with more creativity and provide several solutions for each shot. It seems that decision training has a significant effect in facilitating and providing different solutions.

Introduction: The purpose of this study was to compare the effect of different mental and physical training methods on the motor function of girls and boys.Methods: This study was quasi-experimental research. The statistical sample consisted of 80 male and female students of Boshruyeh City in equal numbers and with a mean age of 14±0.9 years old who were randomly assigned into four groups of 20 participants (Physical Training, Traditional Imagery, PETTLEP, and Control groups). The participants took part in the pre-test and then practiced for six weeks. After training, they participated in the acquisition test To analyze the data, one-way analysis of variance, two-way repeated measures analysis of variance, and LSD post hoc tests were used. A significance level of 0.05 was considered.Results: The results showed that there is a significant difference in motor function between boys and girls based on the different training methods. The motor function of both genders has improved significantly in the Physical Training and PETTLEP groups. Also, the level of motor function of girls and boys was significantly better in the PETTLEP group than in other groups. In addition, Boys in PETTLEP have better motor function than girls.Conclusion: The findings of the study highlight the importance and necessity of paying attention to the methods of physical training and PETTLEP in improving the motor function of students according to their gender. An increase in the motor function of students can be expected especially for boys, by adding the PETTLEP in their training plan.

.Introduction: Exercise has a great effect on health promotion, and recently its effect on improving the nervous system functions and cognitive processes has attracted the attention of many researchers. This study aimed to investigate the effect of internal and external attention during futsal dribbling skill training on the serum level of glial cell-derived neurotrophic factor (GDNF) and cognitive function.Methods: forty-two untrained female students were selected by available sampling and randomly assigned into four Control without training, Control with training, Internal Attention, and External Attention groups. During 15 sessions, the participants of the training groups did the futsal dribbling training according to the dribbling test by making five trials in each session. Forty-eight hours before the pre-test and after the post-test, blood samples were drawn and cognitive function was measured using the Stroop test. GDNF blood factor was measured via the ELISA method. Statistical analysis was conducted at a significance level of P≤0.05.Results: Internal attention during dribbling training had no significant effect on GDNF serum level (P=0.12) and cognitive function (P=0.07). External attention during dribbling training had a significant effect on GDNF serum level (P=0.01) but did not have a significant effect on cognitive function (P=0.16).Conclusion: The type of internal or external attention during futsal dribbling does not make a particular difference in cognitive function and increases the serum level of GDNF. But the effects of external attention on the serum level of GDNF have been significant.

Introduction: Individuals with Down syndrome often exhibit low levels of physical activity and physical fitness, as well as a high prevalence of musculoskeletal disorders. Therefore, this study aimed to develop a sports rehabilitation program based on the systems review of the body function and structure of individuals with Down syndrome.Methods: Articles were searched with an emphasis on "systems review" as a basis and with an overview of "effects" that affect physical activities for people with Down syndrome. Searches were conducted in PubMed, Web of Science, Medline, Google Scholar, and Scopus databases with a combination of keywords related to Down syndrome, body function and structure, the prevalence of disorders, and physical fitness factors. Studies were selected using predefined inclusion and exclusion criteria. After reviewing and studying the articles, recommendations for the content and presentation of an exercise program were extracted based on the literature review.Results: Based on the results and reviews, the rehabilitation exercise program was developed for these people. The sports rehabilitation program requires minimal equipment and can be implemented independently. It also effectively leads to the improvement of gait patterns, strength, stability, balance, coordination, endurance, and participation in purposeful activities with increased independence. This exercise program can be performed three times a week for about an hour per session.Conclusion: According to the content analysis of the unique body function and structure of physiological, neuromuscular, and learning styles of individuals with Down syndrome, the presented comprehensive sports rehabilitation program can improve movement disorders, functional activities, and participation.

. Introduction: The present study aimed to investigate the effect of anodal and cathodal brain tDCS and stimulus-response asynchrony on the backward-compatibility effect (BCE) in conditions of acute mental fatigue.Methods: The participants were 39 boys (20 to 24 years old). The instruments included the informed consent form, the Edinburgh handedness questionnaire, the dual reaction time instrument, the Stroop software, the visual analog scale to evaluate fatigue severity (VAS-F), and the tDCS device. The participants in the pre-test were tested in two conditions of non-fatigue and mental fatigue with a dual reaction time instrument. The tests consisted of two three-choice visual stimulus-response (letters and colors) with ten different stimulus onset asynchronies (SOAs). Then the subjects were randomly assigned to three Anodal, Cathodal, and Sham stimulation groups. The intervention consisted of four consecutive 20-minute sessions of tDCS stimulation on the DLPFC area. One day and four days after the last stimulation session, the tests were repeated. For inferential data analysis, Mixed Model ANOVA and One-way ANOVA tests were used at a significance level of 0.05.Results: The results showed that there is a difference between different SOAs in response time to the first stimulus (RT1) which is a representation of backward adaptation, and at lower SOAs, the RT1 is shorter. Also, there is a difference in RT1 at low SOAs between fatigued and non-fatigued conditions. However, the effect of cathodal and anodal tDCS on RT1 was very small.Conclusion: In general, the results showed that at least some central aspects related to the response can be processed in parallel. Fatigue also affects this parallel processing.

Introduction: The purpose of present study was to test the effect of contextual interference and self-regulation on the transfer of volleyball services (underhand and windmill service).Methods: Participants were 39 male students (20-25 years old) were randomly assigned to one of three groups (blocked, random and self-regulation) and performed total of 40 trials of volleyball service each session (6 sessions). The blocked group practiced 40 trials of one service each session but the random group randomly practiced both services. In self-regulated group, the type of services in each session was determined by subjects. The transfer test was conducted one week after practice period in 5 trials. In order to analyze the data, the one-way analysis of variance and the Tukey’s post hoc tests were used.Results: The comparison between the pre-test and transfer test showed that the difference between blocked and random groups was not statically significant. The self-regulation group had higher transfer scores compared to blocked and random groups.Conclusion: The results of present work support the contexuual interference affect but it’s not significant. Self-regulated practices involve the subjects in learning processes. Also, with his method, they participate more activity in determining the characteristics of the exercise. These factors lead to the improvement of learning and better performance.

.Introduction: This study aimed to compare motor skills in four groups of intellectual disability, Down syndrome, autism spectrum, and normal children.Methods: The research method was descriptive and causal-comparative. The statistical population of this study included children aged 7 to 12 from centers for special needs in Rasht City in 2022. One hundred people (25 participants for each group) were considered as statistical samples. Eight sub-tests of the shortened form of Bruininks-Oseretsky Test of Motor Proficiency - Second Edition (BOT-2) were used to collect data. Analysis of variance test was used to analyze the research data at the significance level of 0.05.Results: The results showed that in the sub-tests of movement speed and agility, balance, strength, reaction time, upper limb dexterity, and the total score of motor proficiency, the performance of children with autism spectrum and Down syndrome was weaker than the other two groups (P=0.001). There was no significant difference between the two groups of normal and intellectually disabled children in the balance and strength subtests (P>0.05). Also, in bilateral coordination and visual-motor control subtests, children with autism had a weaker performance than the other three groups (P=0.001), and no significant difference was observed between the other three groups (P>0.05).Conclusion: Considering the poor motor skills of children with autism spectrum and Down syndrome, and the effect of motor skills on social, academic, and learning skills, it seems necessary to include motor skills training and exercises for children with special needs at younger ages in educational programs of special schools and occupational therapy centers.

Introduction: This research aimed to design and standardize the bodily-kinesthetic intelligence assessment questionnaire in Iranian society.Methods: The current research method was a combination of qualitative and quantitative methods with an exploratory design – an instrument development model. In the qualitative stage, after conducting 12 semi-structured interviews, related categories were collected and after checking the face and content validity, a 36-item questionnaire was designed. In the quantitative stage, the validity and reliability of the researcher-made questionnaire were examined. The statistical sample consisted of 808 teenagers from five provinces of the country who were selected by the multi-stage cluster sampling method and all the subjects completed the questionnaire. To determine the concurrent validity, the KTK3+ motor competence standard test was used, and to check the temporal reliability and consistency, test-retest and Cronbach's alpha coefficient were used.Results: Through exploratory factor analysis, five factors of physical fitness factors related to health and skill, perceptual ability, non-verbal communication, enjoyment and participation in various physical activities, and learning and experience of motor skills were identified and these five factors explained 51% of the total variance. The results of the confirmatory factor analysis showed that the goodness of fit index and the comparative fit index was higher than 0.90. In concurrent validity, the correlation between the scores of the two tests was 0.51 and Cronbach's alpha coefficients (0.89) and intra-class correlation (0.87) were also obtained.Conclusion: In general, it can be concluded that the bodily-kinesthetic intelligence questionnaire has a suitable and acceptable validity and reliability, and by using this questionnaire, the assessment of the bodily-kinesthetic intelligence of teenagers is possible.

Introduction: The mental appraisal and athlete's ability to deal with stressful factors affect the development of negative emotional states and anxiety. Considering the impact of stress and related psychological responses on performance, interventions that reduce stress and may thus increase athletic performance need to be investigated.This study aimed to determine the effect of transcranial Direct Current Stimulation (tDCS) on psychological choking, fear of failure, and shooting performance underpressure in students of Imam Ali Officers’ University.Methods: This quasi-experimental study was conducted with a pre-test and post-test design that includes a control and an experimental group. Forty students of Imam Ali Officers' University participated in this study. In the pre-test and post-test, the fearof failure and psychological choking questionnaires and also shooting performance tests were used. The tDCS was applied for 20 minutes with an intensity of 2 mA overthe dorsolateral prefrontal cortex (DLPFC) region for 10 sessions. Data were analyzed using univariate repeated measures ANOVA test.Results: The results showed that tDCS over DLPFC could reduce psychological choking under pressure but could not change the fear of failure. The results also showed that tDCS can increase shooting performance under pressure.Conclusion: In general, it can be concluded that tDCS probably increase performance-related indicators in high-pressure military environments. However, more studies are needed to find the underlying mechanisms.

Introduction: This study aimed to determine the effects of skilled people’s EEG-Based neurofeedback training on learning of the rifle shooting skills in novices.Methods: This applied study was a semi-experimental research with a pretest-posttest control group design. Thirty novice athletes (mean age: 20±1.509 years) voluntarily participated in this study and were assigned into three homogenous groups including Beta/Theta Neurofeedback, Neurofeedback based on the brain pattern of skilled rifle shooters (decreasing the Theta activity in Fz and F4 area, and increasing the low and high Alpha at the P3 and P7 area, and Control groups according to pretest scores. The acquisition phase consisted of 6 sessions. The control group only did physical exercise during the sessions. 48 hours after the last acquisition session, a retention test was conducted followed by a transfer test by a non-dominant hand to grab the weapon.Results: The results showed that the group with neurofeedback based on the brain patterns of skilled rifle shooters was significantly better than the other two groups in all sessions. In the retention test the group with neurofeedback based on the brain patterns of skilled rifle shooters significantly performed better than the other two groups and the Beta/Theta Neurofeedback group had better performance compared with the Control group. In the transfer test, both neurofeedback groups performed better than the Control group, but there was no significant difference between the two neurofeedback groups.Conclusion: Future research can accelerate the progress and reach the peak shooting performance for novices by correcting neurofeedback protocols according to the brain and the expertise relationship.

Introduction: Multiple sclerosis (MS) is one of the most common chronic inflammatory autoimmune diseases of the central nervous system that affects the motor and sensory systems to control balance while standing and walking. This study aimed to investigate the effect of eight weeks of proprioceptive training on balance, fatigue, and quality of life of women with MS.Methods: The statistical population of this research included 20- to 50-year-old women with MS and a total score of 1 to 4 on the Expanded Disability Status Scale (EDSS) that are members of the Isfahan MS Association. From this population, 30 volunteers were selected conveniently and assigned to experimental and control groups. Participants of both groups completed the Fatigue Severity Scale (FSS), Multiple Sclerosis Quality of Life-54 (MSQOL-54), and Berg Balance Scale (BBS) tests before starting the training program. The experimental group performed 60-minute proprioceptive training for eight weeks and three sessions a week, and the control group performed their daily activities during this period. After 8 weeks of training, both experimental and control groups repeated the previous tests. The data were analyzed using independent and paired t-tests at the significant level of 0.05.Results: The results showed that there was a significant difference in balance, fatigue, and quality of life of the experimental group in the post-test compared with the pre-test (P<0.05). Also, the comparison of the post-test results of the two experimental and control groups showed a significant difference in the balance and quality of life of MS patients (P<0.05).Conclusion: Overall, eight weeks of proprioceptive training improved the balance and quality of life of MS patients, but it was not effective in reducing their fatigue. Therefore, the use of proprioceptive training is recommended for the well-being of MS patients.

The aim of the study was to investigate the psychometric properties of the Iraqi version of the Gross Motor Development Test - Third Edition TGMD-3 in Iraqi children aged 5 to 9 years. The second aim of this study was to compare the development of gross motor skills of Iranian and Iraqi children. The participants were selected from 400 people by cluster sampling method from Iraq and were evaluated using TGMD-3 test. Finally, 30 Iraqis in the age group of 8-9 years were randomly selected and compared with a similar group of 30 Iranian children. Cronbach's alpha, Pearson correlation coefficient, factor analysis and t-test were used to analyze the data. Internal consistency reliability coefficients for locomotor, ball skills and total scores were 0.77, 0.85 and 0.87; test-retest reliability coefficients were 0.89, 0.90 and 0.91; inter-rater reliability coefficients were 0.77, 0.85 and 0.88; intera-rater coefficients were 0.66, 0.80 and 0.84, respectively. Also, there was no significant difference between the performance of Iranian and Iraqi children in the subtests of locomotor and ball skills and the total score of gross motor skills (P <0.05). Due to the confirmation of validity and reliability, this test can be used with confidence to evaluate the development of gross motor skills. The results obtained are limited to the Iraqi boy community of 5 to 9 years, and additional studies are needed in the future for use in the girl community and other age groups.

Introduction: Purpose of the present study was to investigate the effect of virtual reality training on proprioceptive function of elbow joint in hemiplegic children. methods: Twenty boys ranging from 7 to 12 years, from special schools in Tehran, were randomly divided into the experimental and control groups. The devise used for virtual reality intervention was Xbox 360 Kinect (Microsoft, New York, and United State). Gyroscope device was used for measuring elbow’s joint position sense. Participants in the experimental group took part in the Virtual Reality (VR) program; participants in the control group continued their traditional therapy program. Paired sample t test and independent sample t test were used using SPSS software version 18 at p <0.05 level.Results: Results of independent sample t test showed that although a significant difference was no observed in joint position sense between the experimental and control groups during the pre-test phase (t=0.07, df=18, p=0.944); in the post-test phase, virtual training resulted in better scores for the experimental group (t=2.3, df = 18, p=0.03). Based on the results of paired sample t test, virtual training resulted in significant progress for joint position sense in the experimental group. Conclusion: Our results about using VR systems for patients with CP were in agreement with the findings by Denise Reid. VR intervention results in CP children could be justified by self-efficacy and motor learning theories. This type of therapy yields significant improvements for participants, since it lets them explore new experiences that would otherwise be difficult or dangerous.

The participants randomly divided into five groups: Strategic self-tlk as instructional self-talk (N=10), motivational self-talk (N=11), instructional-motivational self-talk (N=10), motivational-instructional self-talk (N=11) and control (N=12). The self-talk intervention conducted for 12 weeks and three sessions per week. In pre-test and post-test, while performing the serve task, the serve score were recorded by the researcher and the gaze behavior of the participants was measured by the eye tracker. The collected data were analyzed using analysis of covariance and Bonferroni's post hoc test.Results: The results of the study showed that strategic self-talk has a significant effect on serve performance (P=0.0001) and the quiet eye duration (P=0.0001). The results of the Bonferroni test showed that instructional self-talk increased motor performance and increased the duration of the quiet eye. In addition, the combined groups that have used this instruction have increased motor performance and a longer duration of quiet eye. However, motivational self-talk has no effect on motor performance and the duration of quiet eye.Conclusion: The results obtained in the current research emphasize the importance of instructional self-talk on the performance and visual attention of novice volleyball players and supports the attention mechanism of self-talk.

ntroduction: The present study was conducted with the aim of validating the accountability questionnaire in physical education.Research method: First, the Student Individual and Social Responsibility Tool (SIPPES) was translated into Persian language to calculate reliability and construct validity. In the implementation stage, the distribution of questionnaires was done in two stages. In the first stage, questionnaires were given to the students to analyze the exploratory factor, and in the second stage, questionnaires were given to the students to analyze the confirmatory factor and convergent validity. In this research, 400 (250 girls and 150 boys) were selected from among 500 fifth and sixth grade students, boys and girls, using available sampling method. To measure the convergent validity, the Sports Behavior Regulation Questionnaire (BREQ, Markland and Tobin, 2004) was implemented.Findings: "Effort", "following class rules" and "self-management" had the greatest effect on the structure of responsible behavior. The reliability of the research was also evaluated as 0.7, which is favorable.Conclusion: Six factors were identified in multistage cluster exploratory factor analysis. ( 1, 7, 13, 9) to the effort component, ( 2, 8, 14, 20) to the self-directed component, ( 3, 9, 21, 25) to follow the class rules (items 4,10,16,22,15) to respect others (5,11,17,23,26) to help others and items (6,12,18,24) to Collaboration indicates that the confirmatory factor analysis also confirmed this six-factor structure obtained. the results showed that this questionnaire has convergent validity and good reliability. Using this tool, it is possible to check responsibility in male and female students.

Introduction: Falling is one of the serious issues of old age that occurs as a result of many factors. It is very important to pay attention to postural and functional indicators in examining and improving the quality of life of the elderly and preventing them from falling. The aim of this research was to compare static and dynamic balance, walking speed, spinal curvature and central stability of elderly people with and without a history of falling.Methods: 60 elderly women aged between 60 and 70 from Tabriz voluntarily participated in the research. the subjects were divided into two groups with and without a history of falling. The fall history of the volunteers was measured by the falls efficacy questionnaire. Static and dynamic balance were evaluated by Sharpand-Romberg and timed up and go tests, respectively. walking speed with 10-meter walk test, central stability with Mc Gill tests, and spinal curvature with flexible ruler were evaluated. Spss statistical software was used for data analysis.Results: The results showed that there was a significant difference between the indicators of static balance, dynamic balance, curvature of the lumbar spine, walking speed and central stability in the elderly with and without a history of falling. However, there was no significant difference between the curvature index of the back spine in the elderly with and without a history of falling.Conclusion: it seems necessary to develop and improve the indicators of balance, walking speed and central stability in people with a history of falling.

Introduction: The present study aimed to investigate the effect of a course of Taekwondo goal-oriented physical exercises on the cognitive functions of children with learning disorders.
Methods: In this quasi-experimental study, which was conducted with a pre-test-post-test control group design, 20 boys with learning disorders were selected from the centers for learning disabilities by referring to special education in Mashhad. In the pre-test stage, the participants' working memory and inhibition were measured by N-back and Stroop tests, respectively. After that, the exercise group participated in the selected Taekwondo exercise program for three 50-minute sessions per week for four weeks. In each session, a set of My Brain cognitive games was used before the implementation of the exercise protocol. In the first 10 minutes of the session, cognitive games were played, then 10 minutes of warming up, 30 minutes of teaching and practicing Taekwondo techniques, and finally 10 minutes of cooling down were conducted. During this period, the control group did their usual activities. Finally, the dependent variables were measured again in the post-test phase. Repeated measures analysis of variance test was used for statistical analysis.
Results: Taekwondo goal-oriented physical exercises improved cognitive functions in the Exercise group; All these changes were significant compared to the control group (P<0.05).
Conclusion: Taekwondo goal-oriented physical exercises can be effective as an intervention to improve the cognitive functions of this group of children.

Introduction: The present study aimed to investigate the moderating role of students' learning styles and emotional intelligence in learning the setting skill in a cooperative method.Method: The research method was a quasi-experimental type, in which 48 female students in the first stage of high school were selected conveniently and were assigned into one of four groups: divergent learning style with low/high emotional intelligence and convergent learning style with low/high emotional intelligence. After the pre-test and passing the course in an educational environment by using the cooperative learning model, the participants took part in the immediate retention, retention, and transfer tests. The measurement tools were Kolb's learning styles questionnaires, Goleman's emotional intelligence questionnaires, and the French and Cooper volleyball tests. In the data analysis, the mean and standard deviation were used in the descriptive statistics section; and in the inferential statistics section, the analysis of variance with repeated measurements and mixed model (4x4) were used at a significance level of 0.05.Findings: The findings indicate that there is a significant difference between the amount of immediate retention, retention, and transfer of volleyball setting skills in a cooperative way in groups with convergent and divergent learning styles and with high and low emotional intelligence; as in the immediate retention, retention, and transfer stages of the group with divergent learning style and high emotional intelligence got the highest score and the group with convergent learning style and low emotional intelligence got the lowest score.Conclusion: it is important to pay attention to the role of learning styles and emotional intelligence of students in teaching setting skills. In addition, it seems that the cooperative learning model is considered a suitable method to use during sports hours.

Introduction: Reactivity to stress is the basis of individual differences in mental, emotional, and physiological responses to stressful situations and is a valid indicator for current and future adverse health outcomes. Despite the importance of stress reactivity and its consequences, the conventional physiological calculation of reactivity is time-consuming, costly, and invasive. This study aimed to determine the validity and reliability of the Persian version of the Perceived Stress Reactivity Scale for Adolescent Athletes (PSRS-AA).
Methods: The research method was a descriptive-correlational type. The statistical sample was made up of 290 athletes (130 girls and 160 boys) of different sports fields with an age range of 12 to 20 years who participated in the present study using the available sampling method. First, the correctness of the translation of the Persian version of the questionnaire was confirmed using the back-translation method, and then confirmatory factor analysis based on structural equation modeling was used to determine the validity of the questionnaire, and Cronbach's alpha coefficient was used to determine the internal consistency.Results The results showed that the goodness of fit index and the comparative fit index are higher than 0.9. Cronbach's alpha coefficient for perceived stress reactivity scale for adolescent athletes and its dimensions were obtained above 0.7 (acceptable index value).Conclusion: Based on the results, based on the results, the Persian perceived stress reactivity scale for adolescent athletes has good and acceptable construct validity and internal reliability, and it can be used as a valid and reliable tool.
