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.

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.

Polycystic ovary syndrome predisposes alterations which contribute to the reduction of quality of life. This randomized controlled clinical trial study was to evaluate the effect of two protocols of aerobic exercise on quality of life in women with polycystic ovary syndrome. Women were allocated to three groups: continuous aerobic training ( n = 28), intermittent aerobic training ( n = 29), and control group (no training; n = 30). Testosterone levels, body composition indices, and quality of life were assessed at baseline and after 16 weeks of intervention. Both protocols were effective to improve testosterone levels, anthropometric indices, and quality of life in polycystic ovary syndrome women. Thus, these protocols should be included in the clinical environment to improve clinical parameters psychological, biological and social health to this population.
