Abstract:   (771 Views)
 Background: Attention Deficit / Hyperactivity Disorder (ADHD) is caused by a disruption in the development of the central nerve which causes deficiencies in the level of attention, especially selective attention in these children. Selective attention refers to the process of rapidly selecting more relevant stimuli than less relevant stimuli and also inhibiting irrelevant stimuli. Researchers believe that attention deficit disorder is the biggest problem for these children, and for this reason, parents and teachers complain that these children do not listen to other people's statements, do not concentrate, leave things unfinished, and are easily distracted. The Stroop test is a common neuropsychological method used to assess executive function, selective attention, and concentration. Various methods have been used to treat this disorder, including physical activity. However, due to the limitations of participating in physical activity, the study of the effect of training methods at different intensities and times in these patients has received more attention than researchers. The aim of this study was to investigate the effect of two acute physical activity protocols on selective attention of children with attention deficit / hyperactivity disorder.
Methods: This is a quasi-experimental study in which a pre-test-post-test design with a control group was used. The statistical population of the study included all children aged 8 to 12 years with ADHD referred to Atieh Derakhshan Mental Clinic in Tehran. In order to select a sample from the statistical population and to diagnose the disorder in children referred, the Connors parent questionnaire and clinical interview were used. Finally, 24 children with ADHD were selected in a targeted and available manner that met the required conditions and were randomly divided into three groups of intense interval activity, cognitive physical activity and control group (8 each). Physical activity protocols were designed by researchers and implemented as a pilot and on a smaller scale. Finally, the experimental groups before and after participating in physical activity and the control group after attending the control conditions were evaluated using stroop test. The data were analyzed by dependent t-test to examine within-group changes and one-way analysis of variance (ANOVA) was analyzed by SPSS 20 software to examine the differences between groups. Significance level less than 0.05 is considered.
Results: The results showed a significant decrease in reaction time (P = 0.010) and error (P = 0.002) subtests in the intense interval activity group, which is the result of a significant effect of this activity on selective attention in children with ADHD. But there was no significant difference in the groups of cognitive physical activity (P = 0.058) and control (P = 0.019). Also, a significant decrease in the time of interference was observed in the group of cognitive physical activity (P = 0.010), which also indicates the effect of this activity on facilitating the performance of these children. Regarding this subtest, no significant difference was observed in the groups of intense interval activity (P = 0.159) and control (P = 0.743). In the intergroup comparison, the results did not show a significant difference between the subtests in the research groups.
Conclusion: Therefore, the results indicate that participation in a session of intense interval physical activity and cognitive physical activity protocols can improve selective attention and facilitate function in ADHD children, respectively, if these protocols can be considered as short-term activities before the child participates in the learning process.
