چکیده
The aim of this study was to investigate the effect of the height of placement (lower and middle) of two types of backpacks (conventional backpack and modified backpack) with 10% of body weight on the kinetic (including 1st and 2nd peak, minimum force, and loading rate) and kinematic (including cadence, step length, step width, swing and double support phases) parameters of gait in schoolchildren. 28 school boys participated in the study after their inclusion and exclusion criteria were considered. They were evaluated by Gaitway treadmill in four conditions including backpack-low, backpack-middle, modified backpack-low, and modified backpack-middle. ANOVA test with repeated measures showed that the mean of the first and second peaks of the backpack-middle was higher than other conditions and had a significant difference with the backpack-low (P<0.05). Among the backpacks, the minimum vertical force in the backpack-low was more than both modified backpack conditions (P<0.05). Given the increase in the first and second peaks of the backpack-middle compared with the backpack-low, it seems better to place the backpack in the lumbar region in terms of forces applied to the body, but this difference was not observed for the modified backpack.

چکیده [English]
هدف از تحقیق حاضر بررسی اثر ارتفاع قرارگیری (پایین و میانه پشت) دو نوع کوله (کوله‌پشتی مرسوم و کوله اصلاح‌شده) با بار 10 درصد وزن بدن، بر پارامترهای کینتیکی (شامل حداکثر نیروی عمودی اول و دوم، حداقل نیرو و نرخ بارگذاری) و کینماتیکی (شامل آهنگ قدم‌برداری، طول و عرض گام، مدت مرحلۀ نوسان و حمایت دوگانه) راه رفتن دانش‌آموزان بود. 28 پسر دبستانی پس از بررسی معیارهای ورود و خروج در پژوهش شرکت کردند و در چهار حالت شامل کوله‌پشتی پایین، کوله‌پشتی میانه، کوله اصلاح‌شدۀ پایین، و کوله اصلاح‌شدۀ میانه پشت با دستگاه تردمیل گیت‌وی ارزیابی شدند. آزمون اندازه‌های تکراری نشان داد میانگین پیک اول و دوم کوله‌پشتی میانه پشت از سایر حالت‌ها بالاتر است و با حالت پایین پشت اختلاف معنادار دارد (05/0>P). بین کوله‌ها نیز حداقل نیروی عمودی در کوله‌پشتی پایین، بیشتر از هر دو وضعیت کولۀ اصلاح‌شده بود (05/0>P). با توجه به افزایش پیک اول و دوم نیرو در موقعیت میانه نسبت به موقعیت پایین در کوله‌پشتی، به‌نظر می‌رسد قرار دادن کوله‌پشتی در ناحیۀ کمر از نظر نیروی وارده به بدن بهتر باشد، ولی این تفاوت برای کولۀ اصلاح‌شده دیده نشد.
