چکیده

چکیدهمقدمه: مطالعات قبلی توصیه کرده‌اند که ترکیب محدودیت کالری و تمرین ورزشی هوازی، نسبت به تمرین هوازی به تنهایی، برای بهبود شاخص‌های متابولیک و سطوح ویسفاتین زنان سالمند چاق بهتر است. هدف از انجام این مطالعه، بررسی اثر 12 هفته تمرین هوازی با و بدون محدودیت کالری بر سطوح پلاسمایی ویسفاتین و شاخص‌های متابولیک در زنان یائسه‌ی سالمند بود.روش‌ها: 60 نفر از زنان یائسه‌ی سالمند با سن 80-60 سال، به طور تصادفی در یکی از 3 گروه 20 نفری تمرین هوازی به همراه رژیم غذایی، تمرین هوازی و رژیم غذایی به تنهایی قرار گرفتند. افراد در گروه رژیم غذایی و ورزش، علاوه بر داشتن برنامه‌ی رژیم غذایی، یک برنامه‌ی تمرین هوازی شامل 45-25 دقیقه، 3 بار در هفته با شدت 75-50 درصد حداکثر ضربان قلب را به مدت 12 هفته اجرا کردند. نشانگرهای متابولیک و سطوح ویسفاتین پلاسمایی در حالت پایه و پایان مطالعه اندازه‌گیری شد.یافته‌ها: پس از 12 هفته مداخله، کاهش قابل توجهی در کلسترول، تری‌گلیسرید، لیپوپروتئین کم‌چگال، گلوکز، انسولین، مقاومت انسولین و سطوح ویسفاتین پلاسما در هر سه گروه و افزایش معنی‌داری در لیپوپروتئین پرچگال در دو گروه ترکیبی و ورزش به تنهایی مشاهده شد (05/0 > P). تغییرات بین گروهی تفاوت معنی‌داری در کلسترول تام، لیپوپروتئین کم‌چگال و تری‌گلیسیرید زنان یائسه‌ی سالمند پس از 12 هفته مداخله را نشان داد (05/0 > P).نتیجه‌گیری: تمرین هوازی همراه با محدودیت کالری متوسط، موجب کاهش قابل توجه در نشانگرهای متابولیک و سطوح ویسفاتین پلاسما در زنان یائسه‌ی سالمند می‌شود.

چکیده [English]

AbstractBackground: Previous findings have suggested that combined caloric restriction and aerobic exercise training is better than aerobic exercise alone for improving metabolic indicators and visfatin levels in obese old women. The aim of this study was to investigate the effect of 12 weeks of aerobic exercise with and without caloric restriction on body composition and visfatin plasma levels in elderly postmenopausal women.Methods: Sixteen elder postmenopausal women aged 60-80 years were randomized in one of the 3 groups of 20 subjects, diet plus aerobic exercise, aerobic exercise and diet only. In addition to the dietary program, subjects in diet plus aerobic exercise group performed an exercise training program of 25-45 minutes, 3 times a week with 50-70 percent of maximal heart rate for 12 weeks. Metabolic indicators including triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (HDL-C), high-density lipoprotein cholesterol (LDL-C), glucose, insulin, insulin resistance, and plasma levels visfatin were measured at baseline and at the end of the study. Data were analyzed using repeated measures analysis of variance (ANOVA) analysis.Findings: After 12 weeks of the intervention, significant decreases in TG, TC, LDL-C, glucose, insulin, insulin resistance, and visfatin plasma levels and increases in HDL-C were seen in the groups (P < 0.05 for all). However, there were significant differences in TC, TG and LDL-C between the groups after 12 weeks of the intervention (P < 0.05).Conclusion: Exercise training with moderate caloric restriction diet induced a significant reduction of metabolic indicators and visfatin plasma levels in older postmenopausal women.
