The aim of this study was to investigate the effect of enamel plate on the frequency variation of theta, alpha and beta brain waves, with emphasis on gender factor as a demographic variable, to answer to following question: How is a cultural luxury item like a enamel plate changing in the comparison between males and females, considering bioelectric activity of the cerebral cortex is affected by the color element. This study is an applied research with semi-experimental design.Electroencephalography was recorded in two regions of F3 and F4 in a commercial video of an enamel plate in four colors, blue, yellow, green and red; and in two groups of males and females. The data was recorded using Biofeedback System 2000 of the Sheffield Corporation during the commercial video demonstration. EEG data were processed using MATLAB software 2018 and statistical comparison was performed using SPSS software version 20 using multivariate analysis of variance analysis. Results showed that the color factor had no significant effect on the power of theta, alpha and beta band frequency. In contrast, the effect of gender was significant and the brain electroencephalography pattern of the participants without color was different in both males and females. The normalized electroencephalographic power of women in all colors was higher than mens’. Therefore, in a cultural luxury product, color cannot have a different effect on the electroencephalogram pattern of the frontal lobe of ​​women and men, but the female cortex is more active than men when processing different colors.

Developmental Coordination Disorder is a common disorder that affects academic and motor performance. This study evaluates the effect of physical exercises on executive function and cognitive flexibility in children with DCD. This research was carried out semi-experimentally with pre-test and post-test. Eighteen children who were screened according to the criteria of The Diagnostic and Statistical Manual of Mental Disorders from 2nd to 4th grade elementary school students in first district of Tehran, then randomly divided into experimental group (nine subjects with a mean age of 8.6 ± 1.39) and control group (nine subjects with a mean age of 8.11 ± 1.15). Executive performance and cognitive flexibility were measured in the pre-test and post-test. The experimental group performed the selected motor exercises for 20 sessions of seventy-five minutes (three sessions per week). Analysis of Covariance was used to data analyze. Comparison of post-test and experimental group showed that the performance of children with developmental coordination disorder after intervention was significantly improved (P = 0.021), but there was no significant change in cognitive flexibility (P = 0.193). The results of this study indicate that physical activity may improve the cognitive basis of motor behavior. Therefore, motor interventions are a safe way to improve the developmental coordination disorder.

The present study investigated the effect of combined post-activation potentiation (PAP) and transcranial random noise stimulation (tRNS) on maximal muscle activity in maximum voluntary isometric contraction test (MVIC) and integrated electromyography (IEMG) when knee extension was kept on the leg extension machine. 10 athlete students from wrestling, track and field and volleyball with mean age of 29/1 years performed one of four protocols that included usual warm-up plus sham tRNS (control group), usual warm-up plus tRNS, usual warm-up plus performing a set of right leg extension (80% of 1 repetition maximal) on the leg extension machine and usual warm-up plus tRNS plus a set of right leg extension in four separate sessions which occurred 24 hours after each other. The brain waves activity levels and electromyogram activity of vastus lateralis, rectus femoris and vastus medialis muscles were recorded simultaneously by using electroencephalography and electromyography respectively when the subjects performed were performing the test. The results showed a significant increase in the absolute power of all three brain waves in the Cz channel for every three conditions of the post-test compared to the pre-test during both MVIC (P=0.001) and keeping leg extension tests on leg extension machine(P=0.001). The amounts of maximum muscle activity for MVIC test and muscle IEMG values during keeping leg extension on the leg extension machine showed a significant increase in every three post-test conditions compared to the pre-test for all muscles (P=0.001). The duration of keeping leg extension on the leg extension machine was significantly increased for every three post-test conditions compared to the pre-test (P=0.001). It seems applying of tRNS and PAP, and also combined use of them after warm up can increase brain activity, maximum muscle activity, integrated electromyography and the duration of keeping leg extension in both tests compering to just warm up. Ultimatly, combined use of tRNS and PAP has an impressive effect compared to applying them separately.

The working memory is the mind's search engine. Working memory is a cognitive function responsible for keeping immediate information, manipulating and its using in thinking. The purpose of this study is to investigate the effect of perceptual-motor programs on the working memory of students with specific learning disabilities with mathematical problems. The present experimental study is a pre-test and post-test one with control group. The target population includes male students from the third to fifth grades of elementary school. All subjects were randomly assigned to experimental (21) and control (20 subjects) groups. Sixteen sessions of peritoneal exercise were performed twice a week for the control group. The research instrument consisted of a revised Wechsler Intelligence Scale for children, a KM test, and a children's illness Symptom questionnaire. Data were analyzed using independent T-test and Covariance analysis. The results showed that after intervention, the experimental group received better scores in the work memory test (P = 0.001), but the post-test control group did not show a change in their working memory scores. According to the results of this study, it is suggested that cognitive-motor exercises should be used to improve the memory performance of children with math disorders.

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.
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.
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.
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 purpose of this study was to investigate the effect of neurofeedback training on balance and reaction time of track and field athletes. 48 athletes in both genders were voluntarily participated in this study and were involved in a double-blind research design including control, sham and two experimental groups; The first treatment group inhibited four-seven Hz and reinforced 15-18 Hz brainwaves at O1 and O2 regions and second treatment group reinforced β1 brainwaves at Cz and Fz regions for 12 sessions and 15 minutes per session. The results showed significant changes in reducing the selective reaction time and improving balance in treatment groups. Based on the results, neurofeedback training can be used to improving perceptual-motor abilities of athletes such as balance and reaction time.

This study attempted to evaluate the effect of engagement with physical activity on happiness of elderly men and women in Tehran city. The study population included all the elderly in 22 regions of Tehran city and 400 subjects were selected by multistage cluster sampling method as the sample of the study. To discriminate active from inactive elderly subjects, Sharkey Physical Activity Questionnaire and to determine the amount of their happiness, Oxford Happiness Inventory (OHI) was used. The reliability and validity of the questionnaires were confirmed. All participants were more than 60 years old and had no psychological and physical disorders. After the questionnaires had been distributed and then collected and the raw data had been classified, SPSS13 software was used to analyze the data. The results of MANOVA at (P<0.0071) showed that active subjects significantly gained higher scores in all the happiness subscales such as life satisfaction, joy, selfesteem, control, efficiency, calmness and totally happiness than inactive subjects while gender and interaction of gender and activity level did not have any significant effect on happiness. Therefore, it can be stated that one of the factors influencing happiness in the elderly is physical activity.

Three dimensional deformity in idiopathic scoliosis of the spine is associated with the deficits on the proprioceptive performance. The aim of this study was to evaluate the effects of balance training with reference to the proprioceptive training on the dynamic balance performance and Cobb angle patients with mild adolescent idiopathic scoliosis. In this quasi-experimental study, twenty girls with adolescent idiopathic scoliosis with mean height and weight of 157.1 ± 5.22 cm and 42.8 ± 5.9 kg were studied. Their minimum and maximum Cobb angle was measured using AP radiography. Using a dynamic stability platform in standing position with opened eyes on stable and unstable platform, their balance performance was measured. Patients underwent four months (54 sessions) balance training with special reference to the proprioceptive training. The measurements were repeated after the exercise therapy. Repeated Measure ANOVA was used for statistical analysis. The postural deviation and body sway of the patients were reduced by 0.97 ± 0.3 and 0.96 ± 0.3, respectively. The greatest improvement in balance performance was obtained, when hip strategy was involved. Exercise training was affected in the reduction of the Cobb angle in 60 % of the subjects (1 to 11 degrees). In 25 % of the patients, the Cobb was not changed and in 15 % of the patients, there was only 1 degree increase on their Cobb angle. According to significant effect of balance training based on the proprioceptive training on the treatment of the scoliotic deformity, the inclusion of the proprioceptive training in the treatment of the mild scoliotic deformity is recommended.
