摘要：مقدمه: هدف از مطالعه حاضر بررسی ارتباط بین تغییرات سطوح سرمی لپتین و هورمون‌های تولیدمثلی، متعاقب یک جلسه فعالیت بدنی در زنان فعال مي‌باشد. مواد و روش‌ها: 20 زن سالم، جوان و فعال تحت مطالعه قرار گرفتند. پس از 12 ساعت ناشتایی (در ساعت 8 صبح)، نمونه‌های خون پیش‌آزمون جمع‌آوری شد. سپس آزمودنی‌ها پروتکل نوارگردان بالک (به‌عنوان فعالیت بدنی منتخب) را به‌اجرا‌درآورده و بلافاصله بعد از آن نمونه خون پس‌آزمون گرفته‌شد. از آزمون t همبسته جهت مقایسه میانگین‌های پیش‌آزمون و پس‌آزمون و از ضریب همبستگی پیرسون برای بررسی روابط استفاده شد. سطح معناداری 05/0>P در‌نظر‌گرفته شد. نتایج: غلظت هورمون‌های لپتین، LH و FSH متعاقب فعالیت بدنی تغییر معناداری نسبت‌به اندازه‌های پیش‌آزمون نداشتند (05/0
其他摘要：Introduction: The purpose of this study was to survey the relationships between changes of serum levels of leptin and reproductive hormones during one session of physical activity in active women. Methods: Twenty active healthy young women were studied. After 12 h of fasting (at 8 A.M.), pre-test blood samples were collected. Then, subjects performed Balk’s treadmill protocol (as selected physical activity), and after it, post-test blood samples were taken. Paired sample t-tests were used to compare pre-test and post-test means, and relationships were calculated by Pearson’s correlation analysis. P value of less than 0.05 was considered statistically significant. Results: Serum leptin, LH, and FSH concentrations remained unchanged after physical activity (P>0.05), while levels of testosterone and estradiol increased (P=0.023, P=0.011 respectively). Serum testosterone and estradiol concentrations were directly correlated to leptin concentration (r=0.47, r=0.43 respectively), while no significant correlations were observed between serum concentrations of leptin and LH or FSH (r=0.21, r=0.17 respectively). Also, there were no significant correlation between changes of leptin and testosterone, estradiol, LH, and FSH (r=0.11, r=0.19, r=0.17, r=0.15 respectively). Conclusion: There are direct correlations between testosterone and estradiol with leptin, while LH and FSH have no relations with leptin. It appears that there are no correlations between changes of serum leptin and reproductive hormones during one session physical activity in active women.
