RESUMO
BACKGROUND: Polycystic ovary syndrome (PCOS) is a polygenic endocrine disorder in women of reproductive ages which will lead to infertility. This study is aimed to determine changes in levels of hyperandrogenism, hirsutism and menstrual regulation after a period of aquatic high intensity interval training (AHIIT) in women with PCOS. METHODS: Thirty patients with PCOS having age between 20 and 35 and body mass index (BMI) ≥30 kg/m2 in obstetrics and gynaecology clinics in Isfahan were selected based on Rotterdam Diagnostic Criteria. They were randomly divided into experimental (AHIIT + metformin, N = 15) and control groups (metformin, N = 15). The exercises were done for 12 weeks, three sessions of 20 minutes. Metformin (1500 mg) was taken daily for 3 consecutive days for 12 weeks. Kolmogorov-Smirnov test, t-test, Covariance and Wilcoxon were applied (P value < 0.05). RESULTS: After 12 weeks, no significant difference was observed in waist-to-hip ratio (WHR), but in AHIIT, the BMI and fat mass significantly decreased and levels of follicle-stimulating hormone (FSH), free testosterone (FT) and sex hormone binding globulin (SHBG) increased compared to control group (P < 0.05). While levels of improvement of total testosterone (TT), dehydroepiandrosterone sulphate (DHEAS), FT, luteinising hormone (LH) and free androgen index (FAI) were not significant between the two groups (P > 0.05). Furthermore, there was a significant decrease in homeostatic assessment of insulin resistance (HOMA-IR) and hirsutism severity in experimental group (P < 0.05). In both groups, the order of menstrual cycles improved significantly (P < 0.05). CONCLUSIONS: Doing AHIIT besides drug therapy can be effective for PCOS patients.
RESUMO
BACKGROUND: Premenstrual syndrome (PMS) is a combination of physical, psychological, or behavioral changes in the late secretary phase of menstrual cycle and interferes with interpersonal relationships or activities. The purpose was to assess the effects of 8 weeks of regular aerobic exercise on PMS in non-athlete girls. MATERIALS AND METHODS: This quasi-experimental study was conducted on 40 non-athlete girl students aged 18-25 years at Khorasgan Azad University, with a diagnosis of PMS. The instruments included personal information and a medical questionnaire, a form of premenstrual symptoms DSM-IV, the GHQ 28 questionnaire, and the Beck Depression and Anxiety questionnaire, and also, daily symptoms were recorded for 4 months (two courses before the training period and two during training). Individuals in the experimental group practiced aerobic exercise for 8 weeks, three sessions per week for 60 min. The subjects were evaluated during the first (the pre-test), second (the mid-test), and third menstrual period (the post-test). Statistical analysis used in this study is t-test and repeated measurement analysis of variance (ANOVA). RESULTS: Results showed that the mean scores of PMS and symptoms declined after 8 weeks of training in the experimental group. The comparison of the two groups showed that the mean scores of PMS, for symptoms during and after exercise, were significantly different (P ≤ 0.001) and the percentages of scores PMS changes, physical, and psychological symptoms of experimental and control groups had a significant difference (P ≤ 0.001) after 8 weeks of training. CONCLUSIONS: Overall, the findings showed that 8 weeks of aerobic exercise is effective in reducing the symptoms of PMS and can be used as a treatment.
