Abstract:Introduction: Basic manipulation skills in children are a prerequisite for movement and sports skills in adulthood. The aim of this study was to compare basic manipulation skills between children with upper cross syndrome and healthy children.Methodology: The statistical population of the study included two groups of healthy boys aged 10-11 years and children with upper cross syndrome in Piranshahr. According to the inclusion criteria, 45 healthy students and 45 students with upper cross syndrome were selected by random and purposive sampling. The Goniometer-pro android app was used to measure kyphosis, the image J program was used to evaluate the head and shoulders forward, and the Ulrich test (TGMD 3) was used to assess the basic manipulation skills. Descriptive statistics, mean and standard deviation were used to describe the data and One-way ANOVA was used to compare the two groups.Results: There was a significant difference between the basic manipulation skills of children with upper cross syndrome and healthy children (p <0.05). In this regard, healthy children in all skills of manipulation, were better than children with upper cross syndrome.Conclusion: Based on the findings, upper cross syndrome abnormality, which is caused by imbalance between agonist and antagonist muscles, causes limitation of movement and weakness in basic manipulation skills of children, so it is necessary to pay attention to these abnormalities.

Impulsivity features of individuals affect their movement patterns when learning sports skills. Therefore, this study examined the effect of different levels of motor impulsivity on learning basketball basic skills. 3 groups of boys aged between 10 and 12 who were selected according to motor impulsivity levels participated in a basketball skills training course along with a control group (the subjects were randomly selected). To evaluate their performance,AAHPERD and Hann basketball pass tests were used in thepretest, posttest, retentionandtransfer phases. The results of covariance and analysis of variance in posttest (P=0.0001) andretention test (P=0.011) inAAHPERD basketball pass showed a significant advantagein this test along with increased motor impulsivity levels.However,better performance were along with decreased impulsivity levelsinHann pass task. The observed differences among the groups were not statistically significantin the transfer phase(P=0.112). It can be concluded that different levels of motor impulsivity is one of the main factors affecting sport skills learningwith regard to the speed-oriented and accuracy-oriented skills.

The aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, left–handed-explicit, and left–handed-implicit. Participants’ task was accuracy and time of sequential reaction. Acquisition phase consisted of 800 practice trials. Participants in explicit practice groups were aware of the arrangement included in stimuli while implicit practice groups were not informed about this arrangement. The day after the acquisition phase, retention and transfer tests were taken. Multiple ANOVA showed that regardless of handedness, implicit practice had more effects on learning reaction time in all three phases of acquisition, retention, and transfer than explicit practice. Regardless of practice type, comparison of right–handed and left–handed subjects was significant in response accuracy in acquisition phase as left–handed subjects were more accurate. The counter effect of handedness and practice type on reaction time and response accuracy was not significant, that is to say right–handed and left–handed subjects had no significant differences in explicit and implicit practice.

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.

tDCS is a neuromodulatory technique that induces a low intensity direct current into brain cells that stimulates or inhibits spontaneous neural activity. In recent decades, electrical stimulation has been used as an effective method to improve balance in different individuals. The aim of this study was to investigate the improvement of postural control kinetic parameters in martial art athletes after applying tDCS. Participants were 20 male martial art athletes aged between 18 and 25. 10 subjects in the experimental group were exposed to electrical stimulation for 1-3 mA for 15-20 minutes and 10 subjects in the control group were exposed to sham tDCS. Then, both groups were evaluated by SOT postural control to exposed variables in sensory organizing test. Data were analyzed using covariance analysis test to differentiate the effect of training interventions on postural control of the two groups (P<0.05). The findings showed that tDCS had a significant effect on the postural control of male martial art athletes in 3 values of equilibrium: the exclusion of information in proprioceptive systems, the exclusion of information in proprioceptive and visual systems and the provision of incorrect visual inputs. Finally, this study showed that tDCS could improve and enhance postural control kinetic parameters in martial art athletes

Aim: This study aimed to determine effect of self-control of task difficulty on accurate and movement pattern golf putting. Methodology: Thirty novice undergraduate students (14 Female and 16 male; average age 21.1 ± 1.64 years) were quasi-randomly assigned to two groups. Before performing each trial during the acquisition phase, the self-control group was told they could choose any of the pre-set distances from the target: (25, 50, 75, 100, 125, 150, 175 and, 200 cm). Each self-control participant’s practice schedule was served as the predetermined practice schedule for each corresponding yoked participant. Participants practiced eight blocks of 10 trials. To analyze the radial error (in acquisition and tests phases) and the movement pattern score (in tests) mixed variance analysis with repeated measures on the last factor was used. The movement pattern score in acquisition phase was analyzed using t test. Results: Based on the results, radial errors across different groups in the acquisition phase did not vary, but the radial error of the self-control group in retention, single task transfer and dual-task transfer tests was lower compared to the yoked group (ps < 0.001). In acquisition and test phases, the golf putting movement pattern was better than that of yoked group (ps < 0.001). Conclusion: The efficacy of self-control of task difficulty is explained with reference to the challenge point framework.

The aim of this study was to determine the psychometric properties and to normalize Persian version of the Self Talk Questionnaire. 384 male and female athletes in three skill levels and 10 sport fields (team and individual) were selected and completed the Persian version of the Self Talk Questionnaire. At first, face validity of this questionnaire was confirmed with translation-back translation method. For construct validity, internal constancy and temporal stability, confirmatory factor analysis, Cronbach alpha coefficient and intra-class correlation coefficient were used respectively. The results showed acceptable fit of the 11-item model of Self Talk Questionnaire; fit index (RMSEA, 0.07; CFI, 0.98 & TLI, 0.97), internal consistency (motivational, 0.70; cognitive, 0.70 & total, 0.73) and temporal stability (motivational, 0.89; cognitive, 0.92 & total, 0.89) showed good reliability and validity of the Persian version of this questionnaire. These findings indicated good validity and reliability for the Persian version of Self Talk Questionnaire. Therefore, the Persian version of Self Talk Questionnaire can be employed as a suitable tool to study and evaluate self talk of Iranian male and female athletes.

The purpose of the present study was to determine the effect of increasing arousal and its effect on athletes' depth perception. Participants of this study included the students of Faculty of Physical Education and Sport Sciences. 58 students (23 female and 35 male, mean age: 23.3 and SD: 2.16) were selected randomly. Participants performed the study tests under two motivational conditions (with viewer and without viewer). The sport competitive anxiety test (SCAT) was performed to test the level of participants' arousal. Moreover, the instrument to test depth perception was the electrical set of depth perception (122B). Results of paired t-test showed a significant difference in scores of depth perception test between the two motivational conditions at 0.05. In other words, participants in high arousal condition (i.e. with viewer) had an inaccurate estimation of depth perception. This effect was the same in both sexes. The results of this study indicated that novice athletes in high arousal condition pay attention to different information resources or different peripheral cues which lead to inaccurate estimation of depth.

Attention is one of the effective factors when learning and performing motor skills. Focus of attention is a method to increase the efficiency and learning. Previous studies have shown that focus of attention plays an important role in learning and performing motor skills. The purpose of the present study was to compare the effect of the instruction of far and near external focus of attention on dynamic balance task performance. In this study, sixty male undergraduate students of Ferdowsi University of Mashhad, who had taken the general physical education course in the second semester of 1388-89, were assigned randomly in three groups: far external attention group (attention to those signs far from the feet), near external attention group (attention to those signs near the feet) and control group (no attentional instruction). The stabilometer (Biodex) was used to collect the data. Each participant performed three 20-second trials in dynamic balance test. The obtained data were analyzed by descriptive statistics as well as inferential statistics such as one-way ANOVA and Duncan post hoc test. The results showed that far external attention group performed significantly better than control group while near external attention group did not reveal any significant difference compared to the control group.

The employment of neurofeedback is growing rapidly in sport performance enhancement. The aim of this study was to investigate the effect of neurofeedback training on motor performance and conscious motor processing of skilled dart players. The subjects were 20 male skilled dart players. The research was conducted in five phases: pretest, neurofeedback training, posttest 1, under pressure test and posttest 2. Neurofeedback training consisted of prevention training of the alpha frequency band (8 to 12 Hz) in F4. To analyze data, descriptive statistics and mixed ANOVA were used. Results indicated that the amounts of conscious motor processing for neurofeedback training group decreased in posttest 1 (P=0.001) and under pressure test (P=0.001) but this reduction was not observed in the control group (P=0.83). The dart throwing points for neurofeedback training group and control group in the posttest 1 increased compared with the pertest (P=0.001), but only neurofeedback group (P=0.001) was able to preserve this increase in the under pressure test. The findings indicated an effect among neurofeedback training, conscious motor processing and sport performance. In other words, the neurofeedback training leads to the desired motor performance and creates automatic sense in the athlete by reducing the conscious motor processing.

The aim of the present study was to investigate the effect of contextual interference on balance of mentally retarded people. For this purpose, 40 educable and mentally retarded boys in Qazvin city (mean age 24.45 ± 3.120) were randomly divided into two groups: blocked and random practice. After the pretest, given their practice arrangement, subjects in each group performed their workout for 4 weeks (3 sessions per week) as the acquisition phase. Acquisition test was conducted in the last session, and then retention and transfer tests were performed after 48 hours. After Kolmogorov-Smirnov test verified normal data distribution and Leven test examined the homogeneity of variances, analysis of variance with repeated measures showed that the intervention was effective and the groups significantly improved (P=0.0005). The results of the independent t test (to compare two groups in static balance) showed that random practice group performed better in retention test (P=0.007) whereas no significant differences were observed between the groups in transfer test (P=0.061). In addition, dynamic balance results showed that random practice group performed better than the blocked practice group and it had a significant difference in retention and transfer tests (respectively P=0.001, P=0.002). So, mentally retarded people can use the beneficial effects of random practice.

The aim of this study was to examine the effect of play-based early intervention on psychomotor development of 4-6-year-old children suffering from autism spectrum disorder. The research design was semi-experimental with pretest-posttest and a control group. 30 qualified children (15 males and 15 females) were randomly selected from 4-6-year-old children of Isfahan city in 2015 by convenience sampling method and assigned to experimental and control groups. Data were collected by Gesell Motor Developmental Scale (1940) completed by parents in pretest, posttest and follow-up. Then, experimental group received ten 90-minute treatment sessions once a week in which children participated in play-based early intervention. Control group received no treatment. Follow-up was conducted 30 days later. Data were analyzed using analysis of variance with repeated measures. Results indicated a significant difference between experimental and control groups in psychomotor development. Moreover, intra-group differences, the interaction between two positions and changes in pretest, posttest and follow-up were significant in psychomotor development. Therefore, it can be concluded that play-based early interventions influence psychomotor development in children with autism spectrum disorder. Such interventions can be applied to improve and enhance these children’s skills.

This study examined the effect of general and specific practice on the presence of a special skill. 24 healthy university students with no history of basketball were selected. After a pretest, they performed constant and variable practice (in constant and variable groups) for 5 weeks and 3 sessions per week. A performance test was conducted at the end of every week and retention and transfer tests were conducted after 2 days of detraining. The ANOVA test with repeated measures was used to analyze data. The results showed that the constant practice was better during performance in practice sessions and the variable practice was better in transfer of the mentioned skill. Also, no differences were observed in basketball throw from the penalty location between constant and variable practice groups in retention test. This finding did not support the hypothesis of special skill in basketball throw skill. Therefore, the coaches and players are recommended to use variable practice for more learning of basketball throw skill.

Aim: One of the issues that have been considered more than before is the issue of aging. An aging is a period that is accompanied by gradual, progressive and spontaneous erosion changes in most physiological devices and functions of the body. One of the widespread problems that occur in the aging process is the loss of balance, increased fluctuations and the risk of falling. Falling down is one of the most common and most serious problems are aging. For this reason, today, many researchers have drawn attention to the various ways in which elderly people develop their balance. Recently, some researchers have found that the use of cognitive strategies such as self-talk can improve the performance of motor tasks. Self-talk, essentially has two main instructional and motivational functions. Motivational self-talk through increased self-confidence and instructional self-talk by enhancing focus on techniques improve their sports performance and learning skills. On the one hand, it is important to increase the effectiveness of the instructions in order to focus on the focus. Wolfe's researches (1998-1992), given the constrained action hypothesis in most sports skills as well as balance skills, suggest that the use of external attention in comparison with internal attention during the skill leads to better performance and learning. Several studies have been conducted on motivational and instructional self-talk about different athletic skills and different skill levels that have led to a variety of outcomes, but few studies have considered the scope of balance. So, the aim of this study was to evaluate the effect of attentional focus types as the self-talk form on static and dynamic balance in elderly women using instructional self-talk focus strategy. Methodology: The present study was a quasi-experimental study with pre-test and post-test. The experimental group included instructional self-talk with internal focus and instructional self-talk with external attention as well as a control group. The population of the study consisted of all elderly women living in the nursing home in Qazvin who 45 people (66.75 ± 5.65 years) were selected according to the inclusion criteria. Inclusion criteria included Lack of movement restrictions, non-fracture in the lower extremities in the past year and the lack of use of neurological drugs. After the pre-test they were randomly assigned to groups. The control group without self-talk, self-talk group with internal focus and self-talk group with external focus practice their balance skills during the five sessions. At the end of the fifth session, the post- test was conducted using static balance (stork) and dynamic balance (timed up and go) tests. In the stork test, the subject must stand on top of his leg, lift the other leg and stick to the knee of the leg, and simultaneously place his hands on the iliac crest of the pelvis. The time that a person could stand open with his eyes was considered as an indicator of his static balance ability. Each subject performed the test three times and the highest time was recorded. The errors that caused the test to be stopped include lifting the hands from iliac crest of the pelvis, detaching the leg from the knee of the foot and any movement on the foot of the reliance.Each subject performed a three-time test of timed up and go, and his best time was recorded. Since the subject was announcing his stand, the timer began to work, and the timer stopped when it hit the subject back with chair. The self-talk group with the instruction of focus of the internal attention, repeated the words "knee and foot" before each loud performance, which meant "bending slightly knees and maintaining the balance on the foot", and the external attention group referred to the term "target and wall" Which meant "looking at the target mounted on the wall.Results: One-way ANOVA, mixed ANOVA and repeated measure ANOVA were used to analyze the data. Data was analyzed using SPSS software version 20. The significance level was considered 0.05. The results showed that both self-talk groups performed significantly better than the control group in static balance.Conclusion: However Self-talk interferences with both types of attentional focus; it was not a significant difference in the dynamic balance of elderly people (P≥0.05). Taking the results into consideration it can be concluded that, self-talk with internal and external focus instructions can be considered as a cognitive strategy to improve the static balance of elderly people.

The aim of the present study was to determine the effects of the number of training sessions in a week on psychological factors and memory of sedentary elderly. For this purpose, 45 sedentary male elderly (mean age, 73.15±6.54 years; height, 166.5±3.10 cm; weight, 64.45±4.06 kg; body mass index (BMI), 23.49±1.51 kg/m2) were voluntarily selected and divided into two training groups and one control group with their own desire. The 8-week training program in two-session group consisted of running with intensity of 40-55% of maximum heart rate for 2 sessions a week. Subjects in four-session group used a training program with similar intensity of two-session group for 4 sessions a week. Depression, anxiety, happiness and memory status were measured using the Beck Depression, Beck Anxiety, Oxford Happiness and Wechsler Memory tests. Data were analyzed using paired t test and one-way ANOVA (P<0.05). The results showed a significant improvement in psychological factors and memory in experimental groups compared with the control group (P<0.05). Subjects who had practiced four sessions a week showed more improvement in depression, anxiety, happiness and some memory factors. Generally, both training programs had useful adaptation and increased number of training sessions has more influence in the improvement of psychological factors and memory in the elderly.

This study aimed at examining the effect of different focus of attention instructions and cognitive styles on the learning of dart throwing skill. 80 children were randomly selected and divided into four equal groups: a) field independent-external attention, b) field independent-internal attention, c) field dependent-external attention and d) field independent-internal attention based on their pretest scores (10 trials of dart throwing). Then, in acquisition phase, they practiced 6 blocks of 10 trials of dart throwing task with regard to their focus of attention and cognitive style. Retention test was conducted 24 hours after the acquisition phase similar to pretest. After ensuring data normality by Kolmogorov-Smirnov test, ANOVA 4*6 with repeated measures was conducted on block factor and one-way ANOVA and Bonferroni post hoc test was applied in acquisition and retention phases respectively. Results showed significant differences in scores of all groups in all phases (P<0.05) and those with field independent style had better performance in external focus of attention than internal focus of attention and those with field dependent style had better performance in internal focus of attention than external focus of attention. In other words, cognitive styles must be noted during recruiting the focuses of attention.

The aim of this study was to evaluate the effect of perceptual-motor training on working memory in children with hearing disorders. For this purpose, 24 student with hearing loss (9-12 years old) in Kermanshah were selected and randomly divided to experimental and control groups. A working memory test by Wechsler memory software was used in this study. The experimental group performed a perceptual-motor training program (static and dynamic balance exercises, throw and receive the ball …) for 8 weeks, 3 sessions per week, 60 minutes each session. Finally, both groups conducted the posttest. Based on α=0.01 and normal distribution of data, mixed ANOVA test was used. The results showed that working memory was influenced by perceptual-motor training (P<0.05). Children in the experimental group showed a better significant performance in terms of counting on forward and visual memory span than control group (P<0.05), but there was no significant difference in the countdown between the two groups (P˃0.05). The present findings suggest that perceptual-motor training can improve working memory in children with hearing loss.
