Stress Hormone and Reproductive System in Response to Honey Supplementation Combined with Different Jumping Exercise Intensities in Female Rats

Abstract

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 (Ex20J, Ex80J), honey (H), and combined honey with 20 and 80 jumps per day (HEx20J, HEx80J) 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 Ex20J and Ex80J compared to C. There was significantly lower value of serum cortisol in HEx20J compared to Ex80J. Serum progesterone levels were significantly lower in Ex20J and Ex80J compared to C. However, serum progesterone levels were significantly higher in HEx20J and HEx80J compared to Ex20J and Ex80J. Relative uterine weights were significantly greater in HEx20J compared to C and HEx80J, 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.

Assessment of Stress on Serum Estradiol and Cortisol Levels in Female Subordinate Naked Mole Rats Following Isolation from Natal Colony

“…In the present study, there was no established relationship between the cortisol and the Estradiol levels. This finding is at variance with a closely related research finding done on the Sprague dowry rats [9] where it was reported that increased serum cortisol levels during exercise led to a decrease in serum progesterone which indicated possible suppression of reproduction by increased cortisol levels-a clear indicator of physiological stress. This finding is also similar to that reported in another study where levels of oestrogen and progesterone were shown to decrease as the responsiveness to stress increased [10].…”

Effects of aerobic, anaerobic, and concurrent training on bone mineral density of rats

“…With respect to the anaerobic training, it presented higher osteogenic potential than aerobic training (swimming) since after just four weeks, it was able to significantly increase BMD with respect to the aerobic swimming training groups (ET4) and the group without training (BL), and the same occurred with concurrent training. In this way, the osteogenic effect of the water jump (anaerobic training) was demonstrated to be effective, even when combined with exercise without impact (aerobic swimming training) 18 . In addition, training with no impact was demonstrated not to be detrimental to BMD, since although it did not increase BMD, it also did not induce significant losses in the deposition of calcium in the bone, and did not detract from the osteogenic effect when combined with anaerobic jump training (concurrent group) 1,2,6 .…”
