مقدمه و هدف: هدف از پژوهش حاضر بررسی تأثیر تمرین مقاومتی حاد با شدتهای خفیف و متوسط بر انعطاف پذیری شناختی سالمندان بالای 60 سال بود. روش شناسی: 40 سالمند سالم بهصورت هدفمند انتخاب و بهصورت تصادفی در یک گروه تجربی (20n=) و کنترل (20n=) طبقهبندی شدند. انعطاف پذیری شناختی توسط وظیفه more-odd طی سه مرحله قبل، 15 دقیقه و 180 دقیقه بعد از برنامه تمرینی قدرتی با شدتهای خفیف (40RM%10) و متوسط (70% RM10) ارزیابی شد. داده ها توسط آزمون آماری آنالیز کوواریانس اندازه های تکراری در سطح معنی داری 05/0 تجزیه و تحلیل شد. یافته ها: نتایج پژوهش نشان داد که تمرین قدرتی (شدت متوسط و خفیف) حاد تأثیر معنیداری بر روی زمان پاسخ، صحت پاسخ و شاخص جابجایی در آزمون وظیفه more-odd در سالمندان دارد. علاوه بر این نتایج پژوهش نشان داد که جنسیت و شدت تمرین اثربخشی تمرین مقاومتی (شدت متوسط و خفیف) بر انعطاف پذیری شناختی را تحت تاثیر قرار نمی دهد، درحالیکه زمان اجرای وظیفه more-odd بعد از تمرین مقاومتی تأثیر معنیداری بر نتایج آزمون دارد. نتیجه گیری: یک جلسه تمرین مقاومتی حاد با شدت های متوسط و خفیف هر دو باعث بهبود انعطاف پذیری شناختی سالمندان می شود.بنابراین توصیه می شود که جهت بهبود انعطاف پذیری شناختی سالمندان و پیشگیری از کاهش عملکرد شناختی آنها از این تمرینات استفاده شود. واژههای کلیدی: تمرین مقاومتی، انعطاف پذیری شناختی، سالمندان | ||

Background &Purpose: Cognitive flexibility is a type of executive function that shows the individual's ability to shift their attention between different tasks and is affected by the aging process. The purpose of the current study was to investigate the effect of acute resistance training with low to moderate intensity on the cognitive flexibility of older adults, aged 60 and above. Methodology: 40 healthy older were purposefully selected and randomly assigned into experimental (n=20) and control groups (n=20). Cognitive flexibility was assessed by the more-odd task, which was conducted in the following three stages: before intervention, 15 minutes, and 180 minutes after intervention. Strength training for the experimental group was performed with low (40% -10RM) and moderate intensity (70% -10RM). The data was analyzed by a 2 × 3 × 2 repeated measures ANOVA at a significance level of 0.05. Results: The results of the study showed that acute resistance training had a significant effect on the response time, response accuracy and shifting index of the more-odd task in the older adults (p <0.05). In addition, the results showed that gender and exercise intensity had no significant impact on the effect of resistance training on inhabitation control (P> 0.05), while the more-odd task which was conducted some time after resistance training had a significant effect on the test results (p <0/05). Conclusion: A session of both moderate and low acute resistance training can improve the cognitive flexibility of older adults. Therefore, it is recommended that these exercises be used to improve the cognitive flexibility of the older adults and to prevent their cognitive decline. | ||
