ObjectiveTo evaluate the effects of continuous (CA) and intermittent (IA) aerobic training on hormonal and metabolic parameters and body composition of women with polycystic ovary syndrome (PCOS).DesignProspective, interventional, randomized study.MethodsRandomized controlled training (RCT) with sample allocation and stratification into three groups: CAT (n = 28) and IAT (n = 29) training and no training [control (CG), n = 30]. Before and after 16 weeks of intervention (CAT or IAT) or observation (CG), hormonal and metabolic parameters, body composition and anthropometric indices were evaluated. Aerobic physical training on a treadmill consisted of 30‐ to 50‐minute sessions with intensities ranging from 60% to 90% of the maximum heart rate.ResultsIn the CA group, there was reduction in waist circumference (WC) (P = .045), hip circumference (P = .032), cholesterol (P ≤ .001), low‐density lipoprotein (P = .030) and testosterone (P ≤ .001). In the IAT group, there was a reduction in WC (P = .014), waist‐to‐hip ratio (P = .012), testosterone (P = .019) and the free androgen index (FAI) (P = .037). The CG showed increases in WC (P = .049), total body mass (P = .015), body fat percentage (P = .034), total mass of the arms (P ≤ .001), trunk fat percentage (P = .033), leg fat percentage (P = .021) and total gynoid mass (P = .011).ConclusionCAT and IAT training reduced anthropometric indices and hyperandrogenism in PCOS, whereas only IAT training reduced the FAI. Furthermore, only CAT training improved the lipid profile.

To our knowledge, this is the first report to show that resistance exercise alone can improve hyperandrogenism, reproductive function, and body composition by decreasing visceral fat and increasing LMM, but it has no metabolic impact on women with PCOS.

Background Polycystic ovary syndrome (PCOS) is a common condition characterized by hyperandrogenism, anthropometric changes (increased weight and waist-to-hip ratio [WHR]), behavioral changes (sexual dysfunction, anxiety, and depression), and reduced quality of life. Physical exercise may reduce many of the adverse effects of PCOS. However, no studies have yet evaluated the effects of aerobic exercise on the sexual function of women with PCOS. Aim To compare the effects of continuous and intermittent aerobic physical training on the sexual function and mood of women with PCOS. Methods This is a secondary analysis of a controlled clinical trial in which women with PCOS (18–39 years of age) were randomly allocated to 1 of 3 groups for 16 weeks: continuous aerobic training (CAT, n = 23), intermittent aerobic training (IAT, n = 22), or no training (control group, n = 24). The Female Sexual Function Index (FSFI) was used to assess sexual function, and the Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression. Main Outcome Measure The main outcome measure used was the FSFI. Outcomes The primary outcomes were changes from baseline in total FSFI score and HAD scores at week 16 to prove the superiority of intermittent aerobic exercise compared with continuous aerobic exercise. Results After 16 weeks, the CAT group had a significant increase in the total FSFI score, improvements in the FSFI domains of satisfaction and pain, and a reduction in the WHR. The CAT and IAT groups also had significantly lower levels of testosterone after 16 weeks. The IAT group had a significant increase in the total FSFI score and improvements in the desire, excitation, lubrication, orgasm, and satisfaction FSFI domains. The CAT and IAT groups both had significant reductions in anxiety and depression scores after 16 weeks. Clinical Implications Aerobic physical training protocols could be indicated to promote mental and sexual health in women with PCOS. Strength & Limitations This is one of the first studies to examine the effects of different physical training protocols on the sexual function of women with PCOS. The limitations of this study are that we did not consider diet or the frequency of sexual relations of participants with their partners. These factors could have interfered with the outcomes. Conclusion The CAT and IAT protocols improved the sexual function and reduced the anxiety and depression of women with PCOS. Both protocols were similar to improve FSFI domain scores.

The aim of this study was to compare metabolic parameters, body composition (BC) and muscle strength of women with and without polycystic ovary syndrome (PCOS). This was a case-control study that evaluated 40 women with PCOS and 40 controls. Androgens and insulin resistance were measured. BC was based on dual-energy X-ray absorptiometry. Isometric handgrip and maximal dynamic muscle strength (1-RM) strength tests were performed. Median total testosterone (p < 0.01), free androgen index (p < 0.01), insulin (p < 0.01) and homeostasis model assessment-insulin resistance (p = 0.02) were higher and sex hormone binding globulin (SBHG) (p = 0.04) was lower in the PCOS group. Normoweight women with PCOS had higher percentages of android body fat. However, the prevalence of android fat distribution was higher in the PCOS than in the control group (p = 0.04). The strength 1-RM in bench press (p < 0.01), muscle strength relative to lean muscle mass in the dominant lower limb (p = 0.04) and isometric handgrip strength tests (p = 0.03) was higher in the PCOS group. PCOS was a determinant of strength in the bench press exercise (p = 0.04). The hyperandrogenism was a predictor of increased strength in biceps curl exercises (p = 0.03) in the dominant lower limb (p = 0.02) and isometric handgrip strength (p = 0.03). In conclusion, women with PCOS have greater muscle strength and a higher prevalence of central obesity, but no difference in BC. Muscle strength may be related to high androgen levels in these women.

Purpose Aerobic exercises may improve quality of life (QoL) in women with polycystic ovary syndrome (PCOS). However, there is no data on the effect of resistance exercise training (RET) programs on the QoL of women with PCOS. Thus, this study aimed to assess the effect of a 16-week RET program on QoL in PCOS women. Methods This 16-week case-control study enrolled 43 women with PCOS (PCOS group, PCOSG) and 51 healthy pre-menopausal controls aged 18 to 37 years (control group, CG). All women underwent a supervised RET program for 16 weeks, and were evaluated in two different occasions: week-0 (baseline), and week-16 (after RET). Quality of life was assessed using the 36-Item Short Form Health Survey (SF-36). Results Testosterone reduced significantly in both groups after RET (p < 0.01). The PCOSG had improvements in functional capacity at week-16 relative to week-0 (p = 0.02). The CG had significant improvements in vitality, social aspects, and mental health at week-16 relative to week-0 (p ≤ 0.01). There was a weak correlation between social aspects of the SF-36 domain and testosterone levels in PCOS women. Conclusion A 16-week RET program modestly improved QoL in women with PCOS.
