چکیده

هدف: هدف مطالعه حاضر بررسی تاثیر مصرف کوتاه مدت مکمل CLA بر میزان چربی سوزی حین فعالیت ورزشی در زنان چاق بود.
روش‌شناسی: آزمودنی‌های این پژوهش 10 نفر زن چاق (سن 7/4±7/34 سال، شاخص توده بدن 8/4±2/34 کیلوگرم بر مترمربع، وزن 9/1±1/83 کیلوگرم) بودند. آزمودنی ها به مدت 7 روز مکمل CLA را روزانه به میزان 5/1 گرم مصرف کردند. قبل و بعد از دوره مصرف مکمل، یک آزمون ورزشی فزاینده روی نوار گردان به منظور سنجش حداکثر اکسیداسیون چربی (MFO) و شدت فعالیت متناسب با آن (FATmax) اجرا شد. نمونه خونی نیز قبل و بلافاصله پس از آزمون فزاینده جهت سنجش میزان سرمی گلیسرول گرفته شد. آزمون های آماری t وابسته و تحلیل واریانس با اندازه‏گیری‏های مکرر جهت مقایسه میانگین متغیرها استفاده شد.
یافته‌ها: تفاوت معنی داری در میانگین FATmax (655/0=p) و MFO (133/0=p) بین قبل و بعد از مصرف مکمل CLA وجود نداشت. مصرف مکمل CLA پس از یک وهله انجام فعالیت ورزشی، تاثیر معنی داری بر مقدار گلیسرول پلاسما نداشت. با این حال، اثر تعاملی بین این دو فاکتور معنی دار بود و میزان گلیسرول را افزایش داد.
نتیجه‌گیری: بطور کلی یافته‫های مطالعه حاضر نشان داد که مصرف CLA، حداقل در کوتاه مدت، سبب بهبود میزان چربی سوزی در زنان چاق نمی‫شود.

چکیده [English]

Aim: The aim of this study was to investigate the effect of short-term CLA supplementation on fat burning rate during exercise in obese women.
Method: The subjects of this study were 10 obese women (age 34.7±4.7 yrs, BMI 34.2±4.8 kg/m2, and weight 83.1±1.9 kg). Subjects consumed 1.5 g/day CLA for 7 days. An incremental exercise test on a treadmill was performed before and after the supplementation period to measure the maximal fat oxidation (MFO) and corresponding intensity (FATmax). Blood samples were taken before and immediately after the test for measuring the serum levels of Glycerol. Paired t-test and ANOVA with repeated measures were used to compare the means of variables.
Results: There was no significant difference in mean FATmax between before and after CLA supplementation (p=0.655). Also, no significant difference was observed in MFO between before and after CLA supplementation (p=0.133). CLA supplementation after one exercise session did not have a significant effect on plasma glycerol; However, the interactive effect of these two factors was significant and increased the glycerol levels.
Conclusion: In general, the findings of this study showed that CLA supplementation, at least in short-term period, does not improve the fat burning rate during exercise in obese women.
