Introduction: The aim of the present study was to compare The effect of mindfulness and PETTLEP imagery on competitive state anxiety and the performance of jumping equestrian athletesMethods: In this semi-experimental research, which was carried out with a pre-test-post-test design with a control group, 30 professional adult equestrians (age range 22 to 40 years old) from Hamadan and Zanjan provinces were selected to participate in the study and were randomly assigned according to the matching methods to three groups: mental imagery, mindfulness practice, and control. In the pre-test and post-test stages, the participants first completed the Persian version of the Competitive Anxiety Inventory-2, and then their jumping performance was measured in a simulated competition by the jury. The intervention phase was carried out over six weeks in one session lasting 90 minutes when the training groups did the desired interventions. Data were analyzed using dependent t-tests, univariate (ANCOVA), and multivariate (MANCOVA) analyses of covariance with Bonferroni's post hoc test.Results: The study's findings revealed that mindfulness training has a significant impact on sports performance (p=0.025), physical anxiety (p=0.030), cognitive anxiety (p=0.015), and self-confidence (p=0.0001). Also, imagery training has a significant effect on sports performance (p = 0.039), physical anxiety (p = 0.016), cognitive anxiety (p = 0.033), and self-confidence (p = 0.033). Other results indicated that there is no significant difference between the effect of mindfulness training and mental imagery on the anxiety, self-confidence, and performance of equestrian athletes in the field of jumping (p<0.05).

Background: Identifying the theoretical frameworks and components of effective interventions in socio-economically disadvantaged communities in order to improve their performance in various aspects of development, can be effective. Essentially, the TGFU approach focuses on the idea of progressing from tactics to skills, not tactics or skills It is commonly assumed that students in a TGFU lesson merely play games with guidance from the teacher, but this is not the caseThe purpose of this research was to investigate The effect of selective training based on a non-linear training approach (the teaching-based on game for understanding) on fundamental motor skills and executive functions of economically disadvantaged children
Methods: The current research was semi-experimental and applied in terms of purpose with a pre-test-post-test design. For this purpose, 30 subjects were randomly divided into two groups of non-linear and linear approach and were trained for eight weeks. Before and after eight weeks, the scores of the gross motor development test-2 and the executive functions questionnaire were collected.
Results: The results of this research showed that a course of selected motor exercises based on a non-linear approach had a greater effect on the subscales of basic motor skills and executive functions of economically deprived children than the linear approach.
Conclusion: According to the perspective of dynamic systems, the factors affecting motor development and executive functions include the characteristics of the motor task in exchange with biological and hereditary factors and the environment.

Introduction: The goal of research is to create a learning environment that can increase learning. This study aimed to investigate the effect of contextual interference on spatial accuracy and motor reprogramming of the sequential motor task in people with Parkinson's disease.Methods: The research method is a quasi-experimental type with a pre-test and post-test research design. 64 people with Parkinson's disease (mean age = 62.93 ± 3) were selected by convenience sampling method and randomly assigned into four equal groups (16 people) including blocked - high similarity, blocked - low similarity, random - high similarity, and random - low similarity. The participants performed 180 trials (12 blocks of 15 trials) for three sequential movement tasks. The error of movement patterns performance was calculated in all stages. In the acquisition stage, the 2 (contextual interference) × 2 (sequence similarity) × 11 (acquisition blocks) ANOVA with repeated measures of the last factor, and for the retention stage, the 2 (contextual interference) × 2 (similarity of sequence) × 3 (stages) ANOVA with repeated measures of last factor, and for the transfer and reprogramming stages, the 2 (contextual interference) × 2 (sequence similarity) ANOVA were used at P=0.05 level of significance.Results: The results showed that in the acquisition phase, the blocked-high similarity group performed better, and the interactive effect of the group and sequence similarity was not significant in the retention and transfer stages. In the reprogramming phase, the random-high similarity group was better.Conclusion: According to the elaboration hypothesis, random practice increases the strength of memory representation and forms deeper processing in memory.

Introduction: Movement is a way of social communication of the child with other people in his life. By moving into the environment, the child gains various experiences, although his skills are not yet developed. This research was conducted with the aim of the effect of aquatic training on the development of social-emotional and gross motor skills of children aged 3 to 6 years.
Methods: The research was quasi-experimental with a pre-test and post-test design with a control group. The statistical population was made up of female preschool children in Faridan city, Isfahan province. 23 people were selected based on the available method and were randomly divided into two experimental groups (n=12) and control (n=11). The experimental group performed 16 sessions of 50-minute training in water for 8 weeks, and the control group performed their activities according to the original programs. Both groups performed the third version of the Ulrich Gross Motor Skills Development Test and the Social Emotional Skills Questionnaire of Gresham and Elliott (1990) under completely similar conditions in the pre-test and post-test. Data analysis was done by multivariate analysis of covariance in SPSS 26 (p=0.05).
Results: The results showed that the aquatic training program significantly led to the development of gross skills (locomotor and ball skills) and more social-emotional skills (cooperation, daring, self-control, and responsibility) than the control group (p≤0/05).
Conclusion: An opportunity can be provided for the development of social-emotional and gross motor skills of preschool girls through an educational program of playing in the water.

Introduction: Manipulate and control the environment, leads to improved motor skills, increased sports participation, and more active social engagement. These factors, in turn, enhance physical and motor competence. This study aims to compare the effectiveness of traditional education and the Teaching Games for Understanding (TGFU) approach in enhancing perceived competence, sports participation, and basketball skills among 10-12 year-old students.
Methods: The present study was semi-experimental. The statistical population of the research included male students 10 to 12 years-old in Meybod City, that 45 people were selected using the available purposive sampling method, and they were randomly divided into three groups of 15 people, including traditional training, TGFU training and control groups. In order to collect data from sports participation motivation questionnaire, perception competence questionnaire, controlled dribble tests, and AAHPERD basketball pass tests were used. In addition, Covariance analysis (ANCOVA) tests and Bonferroni's post hoc test were used to analyze the data at a significance level of P≤0.05.
Results: The results showed that the perceived competence (physical, cognitive and social), sports participation and learning basketball skills (pass and dribble) in the traditional group and TGFU were better than the control group (Sig≤0.05). In the TGFU group, it was significantly higher than the traditional group (Sig≤0.05).
Conclusion: Teachers and coaches can use the TGFU teaching method to increase participation in sports and improve students' competencies, as well as provide an attractive and motivating learning experience for students.

Introduction: The purpose of this research was to study the effect of timing of using strategic self-talk on performance and novices. Methods: 36 new students in basketball skills were selected and randomly divided into three groups: strategic self-talk before providing feedback, after providing feedback, and control. In each session, 60 effort exercises were given from four points of the basketball arc. After every three attempts, the coach gave a feedback to the trainees about how to perform the skill. In the first experimental group, novices were taught to use strategic self-talk after completing three practice attempts and before providing feedback to identify errors; In the second experimental group, the novices were asked to use strategic self-talk after providing feedback to correct errors, and in the control group, exercises and feedback were given, but no self-talk was provided. Finally, two weeks after the end of the intervention, a recall test was held. Results: The results of the two-factor variance analysis in the acquisition phase showed that self-talk both before and after feedback led to improved performance and learning, but no significant difference was observed between the performance of the two self-talk measures in the acquisition phase, but in the memorization phase The strategic self-talk group before giving feedback was better than the self-talk group after giving feedback. Conclusion: it seems that strategic self-talk before re-presentation is beneficial for learning to shoot basketball due to attention to error identification and the use of coach feedback on how to correct errors.

Introduction: There is a contradiction in previous studies about the changes in brain waves as a result of learning. The present research was conducted to compare the power of the Mu rhythm in expert and novice golf players.
Methods: 15 novice students with any experience in golf skills participated in the novice group and 15 experienced golf players in the expert group. The brain waves of participants were recorded while performing 20 trials of golf putting task. Data were processed using the ICA method. For the statistical analysis of the data, a 2×3 (group × area) one-way MANOVA was used.
Results: The results showed that the power of the Mu rhythm in the three central regions (C3, Cz, C4) of the brain of novice and expert golf players has a significant difference (P ≥ 0.05), so the average rhythm power of the expert group was higher than the novice group.
Conclusion: The findings show that the brain function of expert and novice golfers is different. It seems that during the motor learning process of golf putting, the brain undergoes functional changes, and these changes are probably one of the reasons for the better control and execution of skills in expert golfers. The findings highlight the necessity of paying attention to the learning process in improving the control and execution of motor skills. The present study helps experts in training and rehabilitating motor skills to understand the cognitive, neuro-motor processes underlying the execution of actions and skills.

Introduction: The aim of the present research was to determine the effect of task complexity on the bilateral transfer in older adults.
Methods:Thirty healthy elderly men and women with the average age of 68/5±7/40 years were selected by convenience sampling method. Participants perform the Purdue pegboard test, O’Connor dexterity test and the mirror Purdue pegboard test with their dominant and non-dominant hands in pretest. Then, they practiced one of the tasks 6 times by dominant hand and then they participated in posttest and retention test of task. After one week, they started to practice next task and each of the participant attempted a test randomly so that the sequential and learning effect would be eliminated. In posttest and retention test the task was done by both dominant and non-dominant hands. The percentage of progress were calculated by normalization of the time to complete each task during practice compared to the time to complete the task in pretest. The one-way analysis of variance and the Pearson correlation coefficient (P ≤ 0/05)were used for statistical analysis
Results: There were significant differences between progress rate of Purdue pegboard test and mirror Purdue pegboard test and between O’Connor dexterity test and Purdue pegboard test. The amount of time training was a factor associated with bilateral transfer for Purdue pegboard test. Significant correlation was found between the progression rate of Purdue pegboard test and mirror Purdue pegboard test in nondominant hand.
Conclusion:It is likely that compensatory mechanisms have been utilized to maintain performance despite ageing.

Introduction: This study aimed to investigate the effect of dart-throwing exercises with the non-dominant hand on the transfer percentage of dart-throwing accuracy, as well as the variability and coordination of the movement of the dominant hand.
Research Method:In a semi-experimental design, 24 eligible students were randomly assigned to experimental and control groups.The experimental group underwent 12 sessions of dart-throwing exercises with the non-dominant hand using a 10 target effort, while the control group did not engage in any specific exercise. Limb coordination and variability were assessed using the IMU Noraxon device, and accuracy measurements were taken using radial error. Variability and coordination data were analyzed using the SPM programming model in the MATLAB environment, and a two-way repeated measures ANOVA was utilized to analyze behavior data at a significance level of 0.05.
Findings:There was a significant 27% reduction in radial error (p=0.002) and a significant 20 to 50% decrease in the movement variability after exercise (p<0.05); however, there was no significant difference in movement coordination in the experimental group after the exercise sessions (p>0.05). As a result, the transfer percentage of dart-throwing accuracy in the experimental group increased.
Conclusion: The results of this study demonstrated the transfer from the non-dominant limb to the dominant limb. Dart-throwing accuracy in the dominant hand improved, accompanied by a decrease in movement variability. Therefore, it is recommended for coaches and therapists to prevent a decline in the performance of individuals with injuries in their dominant limb by incorporating exercises for the non-dominant limb. limb.
