.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.

In most people getting old is associated with a decrease in both cognitive and motor functions. One of these functions that get affected is reaction time. The aim of this study was to investigate the effect of neurofeedback training protocol variation on the reaction time of elderly people, Which is based on the principle of specificity of training. For this purpose ,Forty elderly participants between the ages of 65 to 70 years were selected and assigned to one of the for groups of experimental groups: 1) neurofeedback at Cz and beta wave, fixed frequency, fixed training arrangement, 2) neurofeedback at Cz and beta wave, fixed frequency, variable training arrangement 3) Neurofeedback at Cz and beta wave, variable frequency, fixed training arrangement, 4) Neurofeedback at Cz and beta wave, variable frequency, variable training arrangement) and 5) control (sham). All groups participated in simple reaction time tests for pre-test and post-test. The analysis of covariance showed that neurofeedback interventions had a significant effect on the reaction time of elderly people (p <0.05) and the frequency and the group with variable training arrangement had the best performance compared to the other groups (p <0.05). According to these results neurofeedback, training affects improving the reaction time of the elderly people and these interventions should be designed based on the principle of specificity of training.

The aim of this study was to investigate the effect of local indigenous games on cognitive function, physical literacy, and academic achievement of children 8 to 12 years old. The participants were 60 male elementary school students with an average age of 10.32. The research was conducted in four phases, include Pre-test,, Training phase in local indigenous games and dynamic courtyard,, Posttest, and Follow-up. The local indigenous games training consisted of twelve traditional-indigenous games that relied highly on physical activity and interpersonal interactions skills. In addition, the control group performed dynamic courtyard training that included some predetermined activity in school. The descriptive statistics and statistical procedures of Mixed ANOVA 2*3 and Bonferroni post-hoc were utilized to analyze data. Results were indicated that the amount of cognitive function for the local indigenous games group was higher than the control group. In addition, the physical literacy of the local indigenous games group was increased more than the control group. Moreover, academic achievement points for the local indigenous games group and the control group in the pre-test to post-test were enhanced, but this increase was higher in the local indigenous games group. The results of this study, were suggested that local indigenous games as a better model compared to the dynamic courtyard model for improving cognitive function, physical literacy, and academic achievement among children 8 to 12 years old.

The aim of this study was to examine the effect of a course of physical exercise on cognitive function and Brain-derived neurotrophic factor in children with Attention Deficit Hyperactivity Disorder (ADHD). This research was performed semi-experimental. Participants included 25 male students aged 7 to 10 years old referred to Ibn Sina Hospital in Mashhad, and randomly divided into two groups (control and experimental). The experimental group participated in an exercise program for 24 sessions, 75 minutes per session. The control group did not receive any intervention. All the participants performed Stroop Test and Go no go Test before and after the exercise. Also, blood samples were taken from these participants to measure serum BDNF before and after exercise. The data were analyzed using ANCOVA. The results demonstrated that cognitive function of the children in experimental group regarding Stroop and Go no go tsts showed significant difference compared with the control group, also Serum BDNF levels showed a significant increase (p<0.05). These results suggest that the organized exercise program helps to improve cognitive function and treat in children with ADHD.

Aging has negative effects on motor and cognitive functions, so it is essential to identify appropriate strategies to prevent the decrease of motor and cognitive functions. The aim of this research was to investigate the effect of vitamin E supplement on motor activity and spatial learning in aged rats. 36 male Albino – Wistar aged rats were assigned to three groups of control, vitamin E and sham. E group received daily 100 mg (50 IU) of vitamin E per kg of body weight with 0.5 ml sesame oil via gavage during 8 weeks. Sham group received daily 0.5 ml sesame oil, but control group did not receive any treatment. After the end of the protocol, open – field and Morris water maze tests were used to respectively assess motor functions and spatial learning. Distance moved and movement speed was used to assess motor function and latency and distance moved to the find platform was used to assess spatial learning. Results showed that in motor function, there was no statistically significant difference among groups in distance moved and movement speed factors (P>0.05). In addition, there was no statistically significant difference among groups in all factors of spatial learning and memory (P>0.05). The results showed that vitamin E did not significantly influence motor and cognitive functions of aged rats. Vitamin E supplement appears not to be efficient in the aging period when antioxidant damages caused irreversible memory destruction.
