چکیده
زمینه و هدف: در مطالعات پیشین مشخص شده است که عوامل زیادی بر اشتها و میزان انرژی دریافتی افراد تأثیرگذار می باشند. تمرین ورزشی یکی از این عوامل می باشد. هدف از پژوهش حاضر مقایسه آثار حاد دوی تناوبی هوازی و تمرین استقامتی با وزنه بر میزان اشتها در مردان دارای اضافه وزن می باشد. روش تحقیق: در طرح یک گروهی با آزمون های مکرر، 12 مرد دارای اضافه وزن (30>BMI>25) به طور داوطلبانه در این پژوهش شرکت کردند. افراد در طی 3 هفته با فواصل یک هفته ای جهت پاک سازی پلاسما به ترتیب تصادفی در موقعیت های دوی تناوبی هوازی، شرایط کنترل و تمرین استقامتی با وزنه در گروه های چهار نفره قرار گرفتند. دوی تناوبی شامل سه وهله 10 دقیقه ای با فواصل استراحتی 5 دقیقه ای با شدت درک فشار بورگ معادل 13 ، و تمرین استقامتی با وزنه انجام 8 حرکت اصلی با 40 درصد یک تکرار بیشینه (1RM) با 20 تکرار بود. میزان اشتها با استفاده از مقیاس اندازه گیری آنالوگ بصری ارزیابی شد. از آزمون t مستقل جهت مقایسه تفاوت میانگین ها در سطح p<0/05 استفاده گردید. یافته ها: میزان تمایل به غذا 9 ساعت پس از تمرین نسبت به پیش آزمون در هر دو جلسه تمرینی دوی تناوبی هوازی و تمرین استقامتی با وزنه، به طور معناداری کاهش یافت(p=0/01). نتایج آزمون t مستقل تفاوت معناداری بین این میزان کاهش تمایل به غذا در دو جلسه تمرینی نشان نداد (p=0/80). میزان احساس سیری 9 ساعت پس از تمرین نسبت به پیش آزمون در هر دو جلسه تمرینی، افزایش یافت؛ اما این تغییر تنها در جلسه تمرین استقامتی با وزنه معنادار( p=0/001) بود. این مقادیر در جلسه کنترل تغییر معناداری نیافت. نتیجه گیری: با توجه به نتایج پژوهش حاضر، تمرین استقامتی با وزنه هم باعث کاهش معنادار تمایل به غذا، و هم افزایش معنادار میزان احساس سیری 9 ساعت پس از تمرین می شود؛ این در حالی است که دوی تناوبی هوازی تنها باعث کاهش معنادار تمایل به غذا می گردد، از این رو می توان گفت تمرین استقامتی برای کاهش اشتها و کمک به تعدیل انرژی دریافتی در مردان دارای اضافه وزن، موثرتر است.

چکیده [English]
Background and Aim: The previous research has indicated that many factors can affect on appetite and energy intake rate. Physical activity can be considered as an important one. The aim of this study was to examine the effects of acute interval aerobic running and endurance weight training on appetite in overweight men. Materials and Methods: In a plan of one group with repeated measures, 12 overweight men (25>BMI>30) voluntarily participated in this study. Participants divided randomly into 3 equal groups including interval aerobic training, endurance weight training, and control groups. Training protocols carried out in 3 weeks with one reating week in order to cleaning of plasma. Interval aerobic training consisted 3 sets, 10 minutes exercises with a 5 minutes interval rest at intensity of 13th Borg scale; and endurance weight training included 8 movements and 20 repetitions at 40 percent of one repetition maximum (1RM). Moreover, the level of appetite was assessed by Visual Analog Scale. Results: The desire to eat was significantly reduced 9 hours after exercise than pre-test in both training groups (p=0.01). The t-test results also showed no significant difference between two type of exercises (p=0.80). Although, the fullness feeling was increased 9 hours after the exercise in both training groups, however, this change was significant only in the endurance weights training group (p=0.001). These values did not significantly change in the control group. Conclusion: In general, according to the present results, the endurance weight training can have a significant effect on desire to eat and also fullness felling 9 hours after exercise than interval aerobic running. The latter had only significant reduction on desire to eat 9 hours after exercise. Therefore, the endurance weight training can be considerd as a good exercise for reducing of appetite level and it can be benefit for overweight men.
