چکیده
هدف این پژوهش مطالعه تاثیر تمرین تداخل زمینه‌ای با استفاده از توپ طبی بر تعدیلات قامتی پیش‌بین سالمندان بود. برای این منظور 30 سالمند به صورت نمونه­گیری در دسترس (دامنه سنی 60-75 سال) انتخاب شدند و به صورت تصادفی به دو گروه تصادفی و قالبی تقسیم شدند. ابتدا در یک پیش­آزمون تعدیلات قامتی شرکت­کنندگان با استفاده از دو صفحه نیرو در هنگام شروع راه­رفتن مورد ارزیابی قرار گرفت. سپس شرکت­کنندگان بر اساس گروه­بندی انجام شده، به پرتاب و دریافت توپ طبی با وزن­های مختلف پرداختند (سه بلوک 36 کوششی). 30 دقیقه بعد از آخرین کوشش تمرینی یک پس­آزمون مشابه با پیش­آزمون اجرا شد. یافته­های پژوهش نشان داد گروه­ها در پیش­آزمون تفاوت معنی­داری ندارند، 05/0<P. اما تفاوت­ها در پس­آزمون معنی­دار بودند، 05/0>P. نتایج نشان داد که گروه تصادفی در پس­آزمون نسبت به پیش­آزمون پیشرفت معنی­داری داشته است05/0>P. هم از نظر زمان و هم از نظر دامنه تعدیلات قامتی پیش‌بین، گروه تصادفی بهتر از گروه قالبی عمل کرد، 05/0>P. این نتایج بر اساس ایجاد بازنمایی قوی­تر بر اثر تمرین تصادفی و همچنین بر اساس نقش نوفه در رفتار جست و جوی فضای راه حل توجیه شدند.

چکیده English

This study aimed to evaluate the effect of Contextual interference training using a medicine ball on anticipatory height adjustments of the elderly. For this purpose, 30 participants (age range between 60-75 years) were selected according to the convenience sampling method and randomly divided into two random and blocked groups. First, in a pre-test, the anticipatory postural adjustments of participants were addressed during the gait initiation. Then, participants performed throwing and catching the medicine ball according to their grouping (3 blocks, 36 trials each). 30 minutes after the last acquisition trial, a post-test was performed, similar to the pre-test. The research findings showed that the groups did not differ significantly during the pre-test. However, the differences were significant during the post-test. The results showed that the random group in the post-test had a significant improvement compared to the pre-test. As a result, both in terms of time and in terms of the range of anticipatory postural adjustments, the random group performed better than the blocked group. According to these findings, it is concluded that an intervention focused on increasing anticipatory postural adjustments, which includes throwing and receiving balls of different weights can increase the time and range of anticipatory postural adjustments and, as a result, improve the stability of the elderly and prevent falling.
