Objective: affect-regulated exercise (‘‘ARE’’) is an alternative approach to guide exercise intensity based on feeling of pleasure. The aim of this study was to analyze if overweight/obese women with polycystic ovary syndrome (PCOS) meet the American College of Sports Medicine (ACSM) recommendation regarding to exercise intensity to improve health status during a single bout of ‘‘ARE". Methods: a sample of 14 overweight/obese women with PCOS (18–34 years) performed a single bout of ‘‘ARE’’ (40 min of aerobic exercise on outdoor track). The Feeling Scale (FS) was used to guide ‘‘ARE’’ intensity/pace maintaining an affective valence between ‘‘good’’ and ‘‘very good’’ during all time. Heart rate (HR), speed, % of HR at first and second ventilatory threshold (VT1 and VT2) and time spent at moderate (64–76% of HRmax) and vigorous (77–95% of HRmax) intensity during ‘‘ARE’’ were measured with a global positioning system (GPS) device. Results: volunteers exercised at 73% (68–78%) of HRmax, 5.8 (5.2–6.2) km/h, 93.4% of HR at VT1 (89.3–98.2) and 80.5% of HR at VT2 (75.3–84.6) and spent 480% of time at moderate intensity. Conclusions: overweight/obese women with PCOS met the ACSM recommendation regarding exercise intensity to improve health status when exercised between ‘‘good’’ and ‘‘very good’’ of FS. Thus, ‘‘ARE’’ may be an interesting approach to be used in clinical practice regarding to exercise prescription and/or physical activity advice

Objective: to evaluate inflammatory markers and insulin resistance (IR) in women with and without polycystic ovary syndrome (PCOS), with different body mass index (BMI). Methods: tumor necrosis factor-alpha (TNF-a), interleukin-6 (IL-6) and C-reactive protein (CRP) were assessed in serum samples from 40 women in reproductive age. Patients were divided into four groups: I (non-eutrophic with PCOS, n¼12), II (non-eutrophic without PCOS, n¼10), III (eutrophic with PCOS, n¼8) and IV (eutrophic without PCOS, n¼10) being non-eutrophic, the overweight and obese women with BMI425 kg/m2 and eutrophic women with BMI524.9 kg/m2. Homeostatic model assessment (HOMA-IR) was calculated for evaluation of IR. Results: PCOS patients showed increased levels of CRP (p50.01) and HOMA-IR (p50.01). When divided by BMI, both non-eutrophic and eutrophic PCOS showed increased CRP levels (p50.01) and HOMA-IR (p50.01). There were no differences in TNF-a and IL-6 levels between groups. Conclusion: in the PCOS group, the levels of CRP and IR were elevated, compared to their counterparts, regardless of body mass
