Continuous versus intermittent aerobic exercise in the improvement of quality of life for women with polycystic ovary syndrome: A randomized controlled trial.

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.

Concordance in prediction body fat percentage of Brazilian women in reproductive age between different methods of evaluation of skinfolds thickness.

OBJECTIVE: To assess the utility of bioimpedance (BIA) and skinfolds thickness (SF) in body fat percentage measuring (%BF) compared to the reference method dual-energy x-ray absorptiometry (DXA) in Brazilian reproductive age women, as well as to estimate of inter- and intra-observer precision for SF. SUBJECTS AND METHODS: 170 women aged 18-37 years with BMI between 18 and 39.9 kg/m2 were selected for this cross-sectional study. Body density was evaluated through equations proposed by Jackson, Pollock and Ward (1980) (EqJPW) and Petroski (1995) (EqPET), and %BF was estimated by BIA, DXA and Siri's formula (1961). The SF were measured by two separate observers: A and B (to determine inter-observer variability), who measured the folds at three times with 10-minute interval between them (to determine intra-observer variability - we used only observer A). RESULTS: The %BF by DXA was higher than those measured by SF and BIA (p<0.01, for all) of 90 volunteers. The Lin coefficient of agreement was considered satisfactory for %BF values obtained by EqJPW and BIA (0.55) and moderate (0.76) for sum of SF (ΣSF) values obtained by EqJPW and EqPET. No agreement was observed for the values obtained by SF (EqJPW and EqPET), BIA and DXA. Analysis of inter- and intra-observer of 59 volunteers showed that different measures of SF thickness met acceptability standards, as well as the % BF. CONCLUSION: BIA and SF measurements may underestimate %BF compared with DXA. In addition, BIA and SF measurements are not interchangeable with DXA. However, our results suggest the equation proposed by Jackson, Pollock and Ward (three skinfolds) compared to BIA are interchangeable to quantify the %BF in Brazilian women in reproductive age. Furthermore, our results show acceptable accuracy for intra- and inter-observer skinfold measurements. Arch Endocrinol Metab. 2020;64(3):257-68.

Increased Sympathetic Cardiac Autonomic Modulation after Two Consecutive Tilt Tests in Women with Polycystic Ovary Syndrome.

OBJECTIVE: The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. METHODS: A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed. Cardiac autonomic modulation was evaluated by spectral and symbolic analyses during two consecutive tilt tests (two moments) and supine moments before, between and after (three moments) the tilt tests. RESULTS: Women with PCOS had higher fasting insulin, HOMA-IR indexes, testosterone and FAI. Additionally, we observed that the PCOS group had greater sympathetic autonomic cardiac modulation in supine 2, tilt 1, and supine 3 moments compared with controls. CONCLUSION: Women with PCOS had higher autonomic sympathetic cardiac modulation even after a second tilt test. No adaptation to this provocative test was observed. Spectral analysis was more sensitive for identifying differences between groups than the symbolic analysis.

OBJETIVO: O presente estudo teve como objetivo analisar a modulação autonômica cardíaca por análise espectral e simbólica da variabilidade da frequência cardíaca (VFC) em mulheres com síndrome dos ovários policísticos (SOP) que foram submetidas a dois testes consecutivos de inclinação. MéTODOS: Um total de 64 mulheres foram selecionadas e divididas em 2 grupos: controle (sem SOP) e SOP. Concentrações de hormônio folículo-estimulante, hormônio luteinizante, prolactina, estradiol, homocisteína, globulina de ligação a hormônios sexuais, hormônio estimulante da tireóide, insulina em jejum, testosterona e androstenediona e níveis de 17-hidroxiprogesterona, triglicerídeos, índice de andrógeno livre (FAI) e homeostase modelo de avaliação (HOMA-IR) foram avaliados. A modulação autonômica cardíaca foi avaliada por análises espectrais e simbólicas durante dois testes de inclinação consecutivos (dois momentos) e momentos supinos antes, entre e após (três momentos) os testes de inclinação. RESULTADOS: Mulheres com SOP apresentaram insulina em jejuM, índices HOMA-IR, testosterona e FAI mais altos. Além disso, observamos que o grupo PCOS apresentou maior modulação cardíaca autonômica simpática nos momentos supino 2, inclinado 1 e supino 3 em comparação aos controles. CONCLUSãO: Mulheres com SOP apresentaram modulação cardíaca simpática autonômica mais alta mesmo após um segundo teste de inclinação. Nenhuma adaptação a esse teste provocativo foi observada. A análise espectral foi mais sensível para identificar diferenças entre os grupos do que a análise simbólica.

Association of measures of central fat accumulation indices with body fat distribution and metabolic, hormonal, and inflammatory parameters in women with polycystic ovary syndrome.

OBJECTIVE: To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters. SUBJECTS AND METHODS: This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women. Free androgen index (FAI) and homeostasis model assessment (HOMA-IR), as well as LAP, VAI, and anthropometric indices, were calculated. The regions of interest (ROIs) in body composition and body composition indices were evaluated using a dual X-ray absorptiometry (DXA). Overall, 32 variables were selected as markers of body fat distribution. RESULTS: Among the 32 markers evaluated, 29 correlated with LAP, whereas 25 correlated with VAI, 19 with body fat (%), and 30 with A/G ratio. Additionally, some markers correlated with the four adiposity indices evaluated: ROIs, except for total mass and leg fat (%); body composition (body mass index, waist circumference, and hip circumference) indices; fasting insulin; and C-reactive protein. CONCLUSION: LAP and VAI may be sensitive measures for screening and preventing metabolic syndrome and insulin resistance in PCOS, with LAP being more sensitive than VAI, and the A/G ratio may be more sensitive than body fat percentage.

Comparison of the Effect of Intermittent and Continuous Aerobic Physical Training on Sexual Function of Women With Polycystic Ovary Syndrome: Randomized Controlled Trial.

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.

Quality of Life in Women with Polycystic Ovary Syndrome after a Program of Resistance Exercise Training.

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.

Resumo Objetivos Exercícios aeróbicos podem melhorar a qualidade de vida (QV) de mulheres com síndrome dos ovários policísticos (SOP). No entanto, não há dados sobre o efeito de um programa de treinamento de exercício resistido (TER) sobre a QV destas mulheres. Assim, este estudo teve como objetivo avaliar o efeito de um programa de TER de 16 semanas na QV em mulheres com SOP. Métodos Estudo caso-controle com 16 semanas de duração, para o qual foram incluídas 43 mulheres com SOP (grupo com SOP, GSOP) e 51 controles saudáveis com received idade entre 18 a 37 anos (grupo de controle, GC). Todas as mulheres foramsubmetidas ao protocolo TER supervisionado por 16 semanas, e foram avaliadas em dois momentos: na semana 0 (linha de base), e na semana 16 (após TER). A qualidade de vida foi avaliada pelo 36-Item Short Form Health Survey (SF-36). Resultados Houve redução significativa da testosterona emambos os grupos após o TER (p < 0,01). O GSOP obteve significativa melhora na capacidade funcional na semana 16 em relação à semana 0 (p = 0,02). O GC apresentou significativa melhora no escore do domínio vitalidade, aspectos sociais e saúde mental na semana 16 em relação à semana 0 (p ≤ 0,01). Houve uma fraca correlação entre os aspectos sociais de domínio SF-36 e o nível de testosterona em mulheres com SOP. Conclusão a aplicação de um programa de treinamento físico resistido durante 16 semanas resultou em melhora modesta da QV de mulheres com SOP.

Resistance Exercise Impacts Lean Muscle Mass in Women with Polycystic Ovary Syndrome.

PURPOSE: This study investigated the effects of progressive resistance training (PRT) on lean muscle mass (LMM) in women with or without polycystic ovary syndrome (PCOS) and its effects on metabolic factors and concentrations of related steroid hormones. DESIGN: This was a nonrandomized, therapeutic, open, single-arm study. PARTICIPANTS: All in all, 45 sedentary women with PCOS and 52 without (non-PCOS), 18-37 yr of age, with body mass indexes (BMI) of 18-39.9 kg·m(-2) of all races and social status, performed PRT three times a week for 4 months. Before and after PRT, the concentrations of hormones and metabolic factors and waist circumference were measured. LMM and total body fat percentage were determined using dual-energy x-ray absorptiometry. Clinical characteristics, LMM, and fasting glucose were adjusted for confounding covariables and compared using general linear mixed models. Each patient's menstrual history was taken before study enrollment and after PRT. RESULTS: PRT resulted in reduced plasma testosterone and fasting glucose levels. After PRT, the androstenedione concentration increased and the sex hormone-binding globulin concentration decreased in women with PCOS. The waist circumference was reduced (P < 0.01) and the muscle mass index, lean mass (LM)/height2, increased in women with PCOS (P = 0.04). Women with PCOS showed increased muscle mass indexes of appendicular LM/height2 (P = 0.03) and LM/height2 (P < 0.01) compared with the baseline. Total LM and trunk LM were elevated in women with PCOS (P = 0.01) at the baseline and after PRT. CONCLUSION: 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.

Women with polycystic ovary syndrome have greater muscle strength irrespective of body composition.

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.
