چکیده

 
تغییر عوامل همودینامیک حین ورزش به نوع و حجم تمرین وابسته است. اما این تغییرات پس از ورزش با محدودیت جریان خون (BFR) کمتر مورد توجه قرار گرفته است. هدف از این تحقیق، بررسی پاسخ حاد برخی عوامل همودینامیک به یک جلسه راه رفتن روی تردمیل با BFR در دختران جوان بود. 30 دختر جوان سالم با میانگین سنی 76/1±27/20 سال و وزن 80/3±61/53 کیلوگرم، که داوطلب شرکت در مطالعه بودند، به‌عنوان نمونۀ آماری انتخاب شدند و به‌طور تصادفی در سه گروه: 1. راه رفتن روی تردمیل با BFR (با شدت 2مایل بر ساعت، 5 ست2 دقیقه­ای با یک دقیقه استراحت بین هر ست)، 2. راه رفتن روی تردمیل بدون BFR (با همان حجم گروه BFR) و 3. کنترل (با BFR و بدون ورزش) قرار گرفتند. ضربان قلب (HR)، فشارخون سیستولیک (SBP)، فشارخون دیاستولیک (DBP)، فشار متوسط شریانی (MAP) و حاصل‌ضرب فشارخون سیستولیک در ضربان قلب (RPP) پیش از شروع جلسۀ ورزش و 20 دقیقه پس از پایان جلسه اندازه­گیری شد. برای محدود کردن جریان خون از دستگاه تورنیکت استفاده شد. MAP با استفاده از فرمول زیر برای هر فرد محاسبه شد:          
MAP=(DBP+0.33(SBP-DBP))
برای تجزیه‌وتحلیل داده­ها از ANOVA استفاده شد. سطح معنا­داری آماری 05/0 P<تعیین شد.
تحلیل داده­ها نشان داد هر دو برنامۀ ورزشی موجب افزایش معنا­دار HR، SBP و RPP در مقایسه با مقادیر پیش از تمرین شد (05/0P<). پس از یک جلسه ورزش، بینRPP ، HR و SBP سه گروه تفاوت معناداری مشاهده شد (05/0P<) و میزان افزایش در گروه BFR بیشتر از گروه بدون BFR بود. این در حالی است که بین مقادیر  DBPو MAP در گروه­های مختلف پس از یک جلسه راه رفتن روی تردمیل با BFR تفاوت معناداری وجود نداشت (05/0P>). نتایج نشان داد BFR موجب تغییر برخی عوامل همودینامیک می­شود؛ که بیانگر افزایش نیازهای عضلۀ قلب در پاسخ به ورزش  BFRاست.

چکیده [English]

 

Changes in hemodynamic parameters during exercise is dependent on the type and volume of exercise. But these changes after exercise with blood flow restriction (BFR) are less considered. The aim of this study was to investigate the acute response of some hemodynamic parameters to a session of walking on a treadmill with BFR in young girls. 30 healthy young girls (mean age 20.27±1.76 years and weight 53.61±3.80 kg) who volunteered to participate in the study were selected as the sample and randomly assigned to 3 groups: 1-walking on a treadmill with BFR (intensity: 2 miles/hour, 5 sets of

 
2 minutes with one minute of rest between each set), 2-walking on a treadmill without BFR (with the same volume of BFR group) and 3-control (with BFR and without exercise). The heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and rate pressure product (RPP) were measured before and 20 minutes after the session. For blood flow restriction, Tourniquet device was used. MAP was calculated using the following formula for each person: MAP = (DBP+0.33(SBP-DBP)). Data were analyzed by ANOVA test. Level of statistical significance was set at P˂0.05. The results showed that both BFR and non-BFR exercises increased HR, SBP, RPP significantly compared with pre-exercise amounts (P˂0.05). After one session of exercise, a significant difference was observed in RPR, HR and SBP among the three groups (P˂0.05). This increase was greater in BFR group than without BFR group while there was no significant difference in MAP and DBP among different groups after a session of walking on the treadmill with BFR (P>0.05). The results showed that BFR changes some hemodynamic parameters which shows that the heart muscle needs increase in response to BFR exercises.
