چکیده مقاله :
هدف از تحقیق حاضر بررسی تاثیر سه ماه تمرین مقاومتی حین دیالیز بر پروفایل چربی و عملکرد جسمانی بیماران دیالیزی بود. در این تحقیق که از نوع نیمه تجربی بود، 34 نفر بیمار دیالیزی به صورت هدفمند به طور داوطلبانه در تحقیق شرکت کردند. آزمودنی ها به طور تصادفی به دو گروه آزمایش و کنترل تقسیم شدند.24 ساعت قبل و 48 ساعت بعد از برنامه تمرینی خون گیری در حالت ناشتا انجام شد و سنجش عملکرد جسمانی نیز با تست 6 دقیقه پیاده روی اندازه گیری شد . آزمودنی های گروه آزمایش به مدت سه ماه، هفته ای سه جلسه و هر جلسه 60 تا 70 دقیقه در تمرینات مقاومتی شرکت کردند که این تمرینات در حین دیالیز روی تخت انجام می شد. برنامه تمرینی شامل10 ایستگاه، 3 نوبت، هر نوبت 10 تکرار با 45 درصد یک تکرار بیشینه بود. از نرم افزار SPSS و آزمون t مستقل و وابسته به منظور تحلیل یافته ها استفاده شد. نتایج آزمون تی وابسته نشان داد که بین پیش آزمون و پس آزمون گروه تمرین در مقادیر LDL (034/0= p)، HDL (021/0= p)، کلسترول (02/0= p) و عملکرد جسمانی(042/0= p) تفاوت معناداری وجود دارد. نتایج تی مستقل نشان داد که تمرین مقاومتی باعث کاهش معنی دار کلسترول (03/0=p) و افزایش معنی دار HDL (004/0= p) و عملکرد جسمانی (05/0= p) در مقایسه با گروه کنترل می شود. اما بر میزان TG (81/0= p) و LDL (1/0=p) تاثیری ندارد. نتایج تحقیق نشان داد که سه ماه تمرین مقاومتی موجب کاهش برخی عوامل خطرزای قلبی عروقی و افزایش عملکرد جسمانی در بیماران همودیالیزی میشود.
The present study aimed to investigate the effect of three-month of resistance exercise on dialysis patients’ lipid profile and physical performance. This study was of a quasi-experimental type. A number of 34 dialysis patients participated in the study voluntarily. Blood samples were taken 24 hours after and before the exercise when the participants did not have breakfast. The subjects of the experimental group participated in pre-planned exercise for three months at three 60 to 70-minute sessions per week. The exercises were done during dialysis when the patients were lying down in bed. The exercise program included 5 to 10 minutes of stretching and limbering as warm up. The main exercise involved ten stations including three sets and ten repetitions by 45% maximum repetition. The subjects were received 1 to 1.5-minute break between the sets and 2 to 3-minute between the stations. In addition, the exercise intensity was enhanced by 5 % once in every two weeks and one repetition was added to SPSS software. Independent t test was used for analyzing the findings. The results indicated that resistance exercise decreased the cholesterol significantly but increased HDL and physical performance in comparison to the control group. The results of the study revealed that resistance exercise decreased some cardiovascular risk factors.
