چکیده

هدف:  افزایش سن با کاهش سطح اینترلوکین15 عضله و سرم و همچنین تحلیل عضلات و در نتیجه کاهش قدرت عضلانی همراه می­باشد. هدف این پژوهش بررسی تاثیر هشت هفتته تمرین مقاومتی با تراباند بر سطوح سرمی اینترلوکین15، تعادل و قدرت عضلانی زنان سالمند بود.
روش‌شناسی: در این پژوهش نیمه تجربی 18 زن سالمند (سن: 79/4 ± 66/73 سال)،(شاخص توده بدن: 25/3 ±  6/25) بطور تصادفی در دو گروه تجربی (10 نفر) و کنترل (8 نفر) تقسیم شدند. برنامه­ی تمرینی گروه تجربی شامل 40 دقیقه تمرین مقاومتی با تراباند به مدت 8 هفته و با تواتر 3 بار در هفته بود. چهل و هشت ساعت قبل و بعد از اجرای برنامه تمرینی میزان تعادل، قدرت پنجه­ها و پایین تنه توسط دینامومتر اندازه گیری شد و نمونه گیری خون از آزمودنی­ها در حالت ناشتا انجام شد و میزان اینترلوکین15 در سرم با روش الایزا اندازه­گیری شد.
یافته‌ها: سطح سرمی اینترلوکین15 (029/0=P) ، تعادل (003/0=P) ،قدرت پنجه دست راست (010/0=P)، قدرت پنجه دست چپ (001/0=P) و  قدرت پایین تنه (001/0=P) در گروه تجربی  نسبت به گروه کنترل  افزایش معنی داری یافته است.
نتیجه‌گیری: بر اساس این یافته­ها می­توان نتیجه­گیری کرد تمرین مقاومتی با تراباند می­تواند به بهبود تعادل و قدرت در افراد سالمند منجر شود و تغییرات ایجاد شده در قدرت بر اثر تمرین مقاومتی با تغییرات اینترلوکین15 ارتباط دارد.

چکیده [English]

Aim: Aging is associated with the reduction of interleukin-15 levels (IL-15), muscles atrophy and consequently loss of muscular strength. The purpose of present study was to investigate the effect of 8-weeks resistance training with Thera-band on the serum levels of IL-15, balance and muscle strength in elderly women.
Method: In a quasi-experimental study, 18 elderly women (age: 73.66 ±4.79 years; BMI: 25.6±3.25) randomly were divided into following groups: experimental (n=10) and control (n=8). Resistance training program included 40 min workouts with Thera-Band for 8 weeks and 3 times per week. Forty eight hours before and after the training protocol balance, hand grip and trunk strength were measured using dynamometer, and blood samples were taken in fasted state. Serum levels of IL-15 were assessed by enzyme-linked immunosorbent assay (ELISA).
Results: The results showed that the serum levels of IL-15 (P= 0.029), balance (P= 0.003) right hand strength (P= 0.010), left hand strength (P=0.001) and low extremely strength (P=0.001) increased significantly in resistance training with Thera- band group in compared to control group.
Conclusion: Based on these findings it could be concluded that Thera-band training may improve the balance in elderly women and there is a relationship between the changes of muscular strength and IL-15 levels.
