چکیده

زمینه و هدف: امروزه چاقی کودکان یک بحران بزرگ بهداشت و سلامت عمومی در سطوح ملی و بین المللی است. ویژگی-های حرکتی مرتبط به چاقی هنوز به طور واضح برای کودکان و نوجوانان مشخص نشده است. هدف مطالعه حاضر بررسی اثر آنی توکفشی طراحی شده اختصاصی بر فعالیت الکتریکی عضلات منتخب ناحیه ساق پای کودکان چاق حین راه رفتن بود.
مواد و روش‌ها: تعداد 14 نفر از دانش‌آموزان پسر در محدودۀ سنی 12-7 ساله شهر همدان به‌طور در دسترس در این پژوهش شرکت کردند. فعالیت الکترومایوگرافی عضلات درشت‌نئی قدامی، نازک‌نئی طویل و دوقلوی داخلی در سه وضعیت راه‌رفتن با کفش، کفش همراه با توکفشی معمولی و کفش با توکفشی طراحی‌شدۀ اختصاصی ثبت گردید. از آزمون آماری آنالیز واریانس با اندازه‌های تکراری همراه با آزمون تعقیبی ضریب تصحیح بونفرونی استفاده شد.
یافته‌ها: نتایج نشان داد که مقدار حداکثر فعالیت نرمالیزه‌شدۀ عضله نازک‌نئی طویل در مرحلۀ میداستانس/ پیشروی راه رفتن، وضعیت کفش با توکفشی طراحی‌شدۀ اختصاصی نسبت به وضعیت کفش (005/0=P) و همچنین در مرحلۀ نوسان، وضعیت کفش با توکفشی طراحی‌شدۀ اختصاصی نسبت به وضعیت کفش با توکفشی معمولی (014/0=P) کاهش معناداری داشت.
نتیجه‌گیری: با توجه به کاهش سطح فعالیت عضلات منتخب ناحیه ساق پا در کودکان چاق حین استفاده از توکفشی طراحی-شدۀ اختصاصی، ممکن است این نوع توکفشی اثرات مثبتی در انجام فعالیت‌های روزانه و حرکات انتقالی برای کودکان چاق فراهم سازد.
