| چکیده | ||
| تمرینات تناوبی سرعتی (SIE) شامل تکرارهایی با حداکثر شدت در مدت کمتر از ۳۰ ثانیه است که موجب بهبود میزان اکسیداسیون چربی در زمان بازیافت پس از تمرین می‌شود. هدف پژوهش حاضر، مقایسۀ تأثیر دو برنامۀ تمرین تناوبی سرعتی بر میزان اکسیداسیون چربی زمان بازیافت در زنان فعال بود. بدین‌منظور ۱۰ زن فعال به‌صورت داوطلبانه (میانگین سن 82/2 ± 8/23 سال، وزن 97/6 ± 2/57 کیلوگرم) در این پژوهش شرکت کردند. آزمودنی‌ها به‌صورت متقاطعبا فاصلۀ زمانی ۶ روز، برنامۀ تمرینی اول (۲۴ تناوب ۵ ثانیه‌ای با استراحت ۴۰ ثانیه) و برنامۀ تمرینی دوم ( ۴ تناوب ۳۰ ثانیه‌ای با استراحت ۲۴۰ثانیه) را اجرا کردند. مدت زمان کار (۲ دقیقه) و استراحت (۱۶ دقیقه) و نسبت کار به استراحت (۱: ۸) در هر دو برنامۀ تمرینی یکسان بود. هزینۀ انرژی و میزان اکسیداسیون چربی بازیافت در مدت ۹۰ دقیقه، با اندازه‌گیری گازهای تنفسی محاسبه شد. میزان اکسیداسیون چربی در زمان بازیافت ۵:۴۰ (۰۸۲/۰ گرم در دقیقه) در مقایسه با تمرین ۳۰:۲۴۰ (۰۹۸/۰ گرم در دقیقه) به‌طور معناداری کمتر بود (0۰۵/۰P<)، اما هزینۀ انرژی زمان تمرین (۱۱/۱۶۰ کیلوکالری) و هزینۀ انرژی بازیافت (۳۱/۱۰۰ کیلوکالری)، به‌طور معناداری در مقایسه با هزینۀ انرژی زمان تمرین ۳۰:۲۴۰ (۴۸/۱۲۷ کیلوکالری) و بازیافت (۲۶/۸۸ کیلوکالری) ۳۰:۲۴۰ بیشتر بود (۰۵/۰P<). نتایج پژوهش حاضر نشان داد، با وجود هزینۀ انرژی بیشتر در تمرین ۵:۴۰ در مقایسه با تمرین ۳۰:۲۴۰، SIEبا دورۀ کار و استراحت طولانی‌تر بر استفاده از چربی در دورۀ بازیافت پس از تمرین تأثیر بیشتری داشت. | ||

| چکیده [English] | ||
| Sprint interval training (SIT) includes repeated bouts of maximal intensity less than 30 seconds, which can improve fat oxidation rate post exercise recovery. Therefore, this study compared the effect of two sprint interval training protocols on fat oxidation rate in recovery in active women. 10 active women (mean age, 23.8 ± 2.82 years, weight, 57.2 ± 6.97 kg) voluntarily participated in this study. Participants completed 2 SIT protocols in a cross-over design with a 6-day interval: the first protocol (24 × 5-sec. bouts, 40-sec. recovery) and the second protocol (4 × 30-sec. bouts, 240-sec. recovery). Protocols matched for the duration of work (2 min.) and recovery (16 min.), as well as the work/recovery ratio (1:8). Energy expenditure (EE) and fat oxidation rate in recovery were calculated by gas exchange collected during 90 minutes. Results showed that fat oxidation was significantly lower during recovery 5:40 (0.082 g/min.) than training 30:240 (0.098 g/min.) (P<0.05). But, EE during training (160.11 kcal) and EE during recovery (100.31 kcal) were significantly higher than EE during training 30:240 (127.48 kcal) and EE during recovery 30:240 (88.26 kcal) (P<0.05). The present results showed that despite the higher EE during training 5:40 compared with training 30:240, SIT with longer work/recovery ratio had a greater effect on using fat during recovery after training. | ||
