Adverse Effect of Different Exercise Types on Ovarian Reserve

Abstract

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.
