چکیده

هدف: با وجود نقش تمرینات هوازی در کنترل دیابت نوع2، هنوز تاثیرگذاری شدت­های مختلف تمرین هوازی و سازوکارهای آن نامشخص است. بنابراین، هدف از پژوهش حاضر بررسی تأثیر هشت هفته تمرین هوازی با شدت کم و متوسط بر سطوح HbA1c، برخی عوامل هماتولوژیک و درصد چربی بدن در مردان مبتلا به دیابت نوع2 بود.
روش‌شناسی: آزمودنی­های پژوهش حاضر را 33 مرد چاق و دارای اضافه وزن مبتلا به دیابت نوع2 با میانگین سنی 03/8 ± 2/43 و شاخص توده بدن (BMI) 71/2±63/28 تشکیل می­دادند که به صورت تصادفی در سه گروه (11 نفر در هر گروه) شامل گروه­های کنترل، تمرین هوازی کم شدت و تمرین هوازی با شدت متوسط تقسیم­بندی شدند. برنامه تمرین استقامتی کم شدت با شدت 50 درصد ضربان قلب بیشینه (MHR) و تمرین استقامتی متوسط با شدت 70 درصد MHR اجرا شد. برنامه تمرینی به مدت 8 هفته و 3 جلسه در هفته به مدت 60-45 دقیقه در هر جلسه ادامه یافت.
یافته‌ها: نتایج نشان داد که HbA1C، گلوکز و درصد چربی بدن در هر دو گروه تمرین کرده به صورت معناداری (05/0>p). کاهش یافته است. با وجود این، بهبود معنادار نیمرخ لیپیدی تنها در گروه تمرین با شدت متوسط مشاهده شد. همچنین، کاهش HbA1C و افزایش VO2peak در گروه شدت متوسط نسبت به گروه شدت کم معنادار بود.
نتیجه‌گیری: به نظر می­رسد شدت پایین تمرینات ورزشی هوازی در مقایسه با تمرینات هوازی با شدت متوسط با سازگاری­ها و بهبود کمتری در وضعیت بیماران مبتلا به دیابت نوع2 همراه است.
واژگان کلیدی: دیابت شیرین، عوامل هماتولوژیک، تمرین استقامتی،  درصد چربی بدن، هموگلوبین گلیکوزیله

چکیده [English]

Aim: despite role of aerobic exercise training in controlling type 2 diabetes, effectiveness of different aerobic training intensity’s and their mechanism is unknown. Therefore, the aim of present study was to investigate the effect of eight weeks' low and moderate intensity aerobic training on levels of HbA1C, some hematological parameters and percent body fat in men with type 2 diabetes.
Method: subjects in present study was consist of 33 obese and overweight men with type 2 diabetes with average age of 43.2 ± 8.03 and BMI 28.63 ± 2.71 that randomly assigned in three groups (11 in each group) including control, low intensity aerobic exercise training and moderate intensity aerobic training. Low intensity aerobic training program were performed with 50 percent of maximum heart rate (MHR) and moderate intensity aerobic training with 70 percent of MHR. Training program continued for eight weeks and three sessions in week for 45-60 minutes in each session.
Results: results indicated that HbA1C, glucose and percent body fat significantly (p<0.05) decreased in both training groups. However, lipid profile significantly was improve only in moderate intensity aerobic training group. Moreover, HbA1C decrease and VO2peak increase in moderate intensity group was significantly diffrent to low intensity group.
Conclusion: It seems that low intensity aerobic training in comparison to moderate intensity aerobic training are associated with lower adaptations and improvement in type 2 diabetes patient.
