This study was performed to determine the effects of 8-week honey supplementation combined with different jumping exercise intensities on serum cortisol, progesterone, estradiol, and reproductive organs. Eighty-four 9-week-old female rats were divided into 7 groups: baseline controls (C0), sedentary group (C), 20 and 80 jumps per day (Ex(20J), Ex(80J)), honey (H), and combined honey with 20 and 80 jumps per day (HEx(20J), HEx(80J)) groups. Jumping exercise was performed at 5 days/week and honey was given at a dosage of 1 g/kg body weight/day for 7 days/week. The level of serum cortisol was higher in Ex(20J) and Ex(80J) compared to C. There was significantly lower value of serum cortisol in HEx(20J) compared to Ex(80J). Serum progesterone levels were significantly lower in Ex(20J) and Ex(80J) compared to C. However, serum progesterone levels were significantly higher in HEx(20J) and HEx(80J) compared to Ex(20J) and Ex(80J). Relative uterine weights were significantly greater in HEx(20J) compared to C and HEx(80J), respectively. There was no significant difference in estradiol level and relative ovarian weights among all the groups. Therefore, honey elicited beneficial effects in reducing the increase of cortisol and in increasing the reduce of progesterone levels induced by different intensities jumping exercise in female rats.
本研究旨在确定为期8周的蜂蜜补充剂联合不同强度跳跃运动对血清皮质醇、孕酮、雌二醇和生殖器官的影响。将84只9周龄雌性大鼠分为7组：基线对照组（C0）、久坐组（C）、每天20次和80次跳跃组（Ex(20J)、Ex(80J)）、蜂蜜组（H）以及蜂蜜联合每天20次和80次跳跃组（HEx(20J)、HEx(80J)）。跳跃运动每周进行5天，蜂蜜以1 g/kg体重/天的剂量给予，每周7天。与C组相比，Ex(20J)和Ex(80J)组的血清皮质醇水平更高。与Ex(80J)组相比，HEx(20J)组的血清皮质醇值显著降低。与C组相比，Ex(20J)和Ex(80J)组的血清孕酮水平显著降低。然而，与Ex(20J)和Ex(80J)组相比，HEx(20J)和HEx(80J)组的血清孕酮水平显著更高。与C组和HEx(80J)组相比，HEx(20J)组的相对子宫重量分别显著更大。所有组之间的雌二醇水平和相对卵巢重量没有显著差异。因此，蜂蜜在降低雌性大鼠不同强度跳跃运动诱导的皮质醇增加以及提高孕酮水平降低方面具有有益作用。
