چکیده
بیشتر مطالعات اغلب تمرینات مقاومتی سنتی را در زمان‌بندی تمرین به‌کار برده‌اند و اثر تمرینات مقاومتی با محدودیت جریان خون در زمان‌بندی تمرین روشن نیست. بنابراین، هدف از تحقیق حاضر، مقایسۀ تأثیر ترکیب هشت هفته تمرین مقاومتی با محدودیت جریان خون و تمرین مقاومتی سنتی به‌صورت زمان‌بندی خطی و موجی بر هایپرتروفی، قدرت، استقامت و توان عضلانی دختران فعال بود. 26 دختر فعال به‌صورت تصادفی در سه گروه تمرین مقاومتی بدون زمان‌بندی، زمان‌بندی خطی و زمان‌بندی موجی قرار گرفتند. شدت تمرین مقاومتی سنتی 75 درصد و شدت تمرین مقاومتی با محدودیت جریان خون 30 درصد یک تکرار بیشینه بود. در گروه زمان‌بندی خطی، 4 هفتۀ اول تمرین مقاومتی با محدودیت جریان خون و 4 هفتۀ دوم تمرین مقاومتی سنتی و در گروه زمان‌بندی موجی، یک روز تمرین با محدودیت جریان خون و روز دیگر تمرین مقاومتی سنتی و در گروه بدون زمان‌بندی، تمرین مقاومتی سنتی با شدت ثابت انجام گرفت. برای تحلیل آماری از آزمون تحلیل واریانس یکطرفه استفاده شد. نتایج نشان داد که افزایش معنا‌داری از پیش‌آزمون به پس‌آزمون در تمام گروه‌ها برای سطح مقطع عضلات راست رانی و پهن داخلی، قدرت و استقامت عضلات چهارسرران و همسترینگ و توان انفجاری پاها مشاهده شد. تفاوت معنا‌داری بین گروه‌ها در هیچ‌یک از متغیرها به‌غیر از سطح مقطع عضلۀ پهن میانی وجود نداشت. ترکیب تمرین مقاومتی سنتی و تمرین با محدودیت جریان خون به هر دو شکل زمان‌بندی خطی و موجی تأثیرات مشابهی با تمرین مقاومتی بدون زمان‌بندی بر هایپرتروفی، قدرت، استقامت و توان انفجاری پاهای دختران فعال دارد.

چکیده [English]
Most studies have commonly utilized traditional resistance training in training periodization and the effect of resistance training with blood flow restriction is not perfectly clear in this periodization. Therefore, the aim of this study was to compare the combination of eight weeks of resistance training with blood flow restriction and traditional resistance training based on linear and undulating periodization on hypertrophy, strength, muscular endurance and power in active girls. 26 active girls were randomly assigned to three groups: resistance training with no periodization, linear periodization and undulating periodization. Traditional strength training (TST) was performed with the intensity of 75% 1RM and blood flow restriction training (BFRT) was performed with the intensity of 30% 1RM. In linear periodization group, subjects performed BFRT during the first 4 weeks and TST during the second 4 weeks. In undulating periodization group, participants switched from BFRT to TST every session. The non-periodization group performed TST with constant intensity. For analyzing the data, one-way ANOVA was used. The results showed a significant increase in all groups from pretest to posttest for rectus femoris and vastus medialis cross sections, strength and endurance of quadriceps and hamstring and explosive power of legs. There was no significant difference among the groups in no variables except for vastus intermedius cross section. Combination of BFRT and TST in the form of linear or undulating periodization and non-periodization resistance training have both similar effects on hypertrophy, strength, endurance and explosive power of legs in active girls.
