نقش تمرینات بازی‌محور بر خودپنداره بدنی دانش‌آموزان دارای اضافه‌وزن با اختلال هماهنگی رشدی

روش‌‌ها: پژوهش حاضر از مطالعات نیمه‌تجربی می‌باشد که در آن 50 کودک 10-8 ساله با استفاده از روش نمونه‌گیری هدفمند و براساس معیارهای ورود به پژوهش از بین مدارس ابتدایی انتخاب شدند و پس از انجام پیش‌آزمون به‌ طور تصادفی در دو گروه آزمایش (30=n) و کنترل (20=n) قرار گرفتند. در مرحله پیش‌آزمون و پس‌آزمون برای سنجش اختلال هماهنگی افراد از آزمون رشد حرکتی mabc-2 (movement assessment battery for children) و برای بررسی خودپنداره بدنی از پرسشنامه wilson استفاده شد. گروه آزمایش به مدت سه ماه در تمرینات شرکت نمودند و نتایج آزمون‌ها در مرحله پس‌آزمون با استفاده از نرم‌افزار spss 21 و آزمون تحلیل کوواریانس یک طرفه در سطح معناداری 0.05 تجزیه و تحلیل گردیدند. نتیجه‌گیری: دوران کودکی یکی از مراحل مهم در شکل‌گیری خودپنداره می‌باشد. بر مبنای نتایج، بازی آثار سودمندی بر رشد اجتماعی و روانی کودکان دارای اضافه‌وزن و مبتلا به اختلال هماهنگی (که بیشتر در معرض مشکلات عاطفی هستند) دارد.

Effect of Game-centered Exercises on the Physical Self-concept of Overweight Students with a Developmental Coordination Disorder

Background: Body composition changes affect different physical, motor, and mental aspects of individuals. Self-concept weakness poses a serious problem for both overweight children and children with developmental coordination disorder. In this regard, the present study aimed to assess the effect of play-based exercises on the self-concept of overweight children with developmental coordination disorder. Methods: This semi-experimental study was conducted on a total number of  50 children aged 8-10 years which were selected from elementary schools using the targeted sampling method and based on entry criteria. Following the pre-test, the participants were randomly assigned to the experimental group (n = 30) and control group (n = 20). In pre-test and post-test, the Movement Assessment Battery for Children (MABC-2) was used to measure the coordination disorder of subjects, and their physical self-concept was assessed using Wilson questionnaire. The experimental group underwent training for 3 months. In post-test, the data were analyzed in SPSS software (version 21) using a one-way analysis of covariance (ANCOVA) at a significant level of 0.05. Findings: As evidenced by the obtained results, a significant difference was detected between the scores of self-concept and subscales, including coordination, desirability, self-esteem, flexibility, and appearance between the two groups. Nonetheless, no significant difference was observed in the components of strength, endurance, physical activity, and health. Conclusion: Childhood is one of the important stages in the formation of self-concept. Based on the results, games can exert beneficial effects on the social and psychological development of overweight children with coordination disorders who are more exposed to emotional problems.
