In this study, it was aimed to determine the negative effect of different types of exercise on ovarian reserve of sedentary women. A total of 40 sedentary women who met the criteria for admission to work were categorized as aerobic exercise (AE; n:20; age: 33.0±2.0 years old) and strength exercise (SE; n:20; age: 32.7±2.1 years old) groups. Participants in both groups received two different exercises of 60-minute with an intensity of 60-70% for 16 weeks and 4 days per week. Participants' anthropometric (body weight, BMI, waist and hip circumference, waist and hip rate (WHR)), estradiol (E2), luteinizing hormone (LH) follicle stimulating hormone (FSH), and levels antimülerian hormone (AMH), which used as over-reserve indicators, were measured for before and after exercise. Comparisons of these parameters were evaluated at p<0.01 and 0.05 levels. The mean of anthropometric and biochemical parameters of the AE and SE groups were statistically similar in before exercise. After exercise program, body weight, BMI, waist and hip circumference values of both groups were significantly decreased (p<0.01 and p<0.05). There was no significant correlation between AMH, E2, FSH and LH levels of the AE group (p>0.05). In the SE group, there was a decrease in AHM level (p<0.05) and an increase in FSH level (p<0.01). There was no significant correlation between E2, and LH levels of the SE group (p>0.05). As a results; strength exercise triggers to decrease in serum AMH levels and to increase in serum FSH levels. For this reason, strength exercise practices can have negative consequences for fertility, especially for women with lower ovarian reserve values.

Background: The objectives of this study were to verify effects of step-aerobic exercise (SAE) and jogging-walking exercise (JWE) program on myokines and adipokines levels in overweight sedentary females., Methods: Volunteer subjects (N.=25) were assigned to two exercise groups: steps aerobics and jogging-walking. The exercise program given to them was for five days a week and for twelve weeks period. Serum samples were collected from venous blood before and immediately after Cardio-Respiratory Fitness Test (CRF) by Bruce protocol and stored at -80 °C until they were assayed before 12 weeks exercise program. After 12-weeks training program this procedure was repeated. Serum TNF-α, IL-6, IL-15, IL-17, IL-18, leptin, resistin and adiponectin levels were assayed by ELISA., Results: Leptin and IL-15 levels were increased whereas resistin levels were decreased after CRF Test in JWE training group following 12-weeks exercise program. TNF-α, IL-15 and IL-18 levels were higher and leptin levels were lower in SAE group than JWE group after 12-weeks exercise period. However, both SAE and JWE did not lead to significant change in serum levels of IL-17, IL-6 and adiponectin levels., Conclusions: This study has added to existing knowledge that both SAE and JWE may cause weight loss especially in fat mass. But, the effect of SAE and JWE on myokines and adipokines levels may be the different. Further studies are needed to find out clinical importance of these findings.
