Introduction: Differents training protocols with exercises have been carried out with women with Polycystic Ovary Syndrome (PCOS), in different contexts and applicability, showing positive results on the clinical and metabolic alterations related to PCOS. However, there are some gaps in the psychological and clinical responses derived from high-intensity interval training (TIAI). Objective: To investigate the effects of High Intensity Interval Training (TIAI) and detraining on the quality of life and mental health of women with Polycystic Ovary Syndrome (PCOS), and to describe the psychophysiological responses (i.e, subjetive perception of effort and response affective) of this population throughout the TIAI sessions. Methods: This study was conducted in two stages: in the first, it was characterized as a cross-sectional and descriptive study, in which 12 women with PCOS participated (mean age 26.2 ± 4.1); and the second included a pilot randomized clinical trial with 23 women with PCOS (mean age 26.0 ± 3.92) who were allocated to a control group (n = 11) and a supervised TIAI group (n = 12). Women with PCOS were included; no use of medications for at least 3 months; without exercising in the past six months or sedentary. Exclusion criteria were: pregnant women; cardiovascular diseases; positive response on PAR-Q; and any other contraindication for the practice of physical activity. Anamnesis, physical activity level questionnaires (IPAQ), health-related quality of life (SF-36), depression, anxiety and stress scale (DASS-21), perceived exertion assessment (PSE, Borg CR scale) were applied. -10) and affective responses (FS, feeling scale), body composition (DXA), anthropometry and metabolic profile analysis. The interventions consisted of 10 50-min TIAI running sessions [intervals of 10 x 1 min at 90% of maximum heart rate (HRmax) interspersed with 3 min of active recovery periods at 70% of HRmax], including 5 minutes of warm-up and cool down at 48 hour intervals (first step). In the second stage, the TIAI intervention lasted 12 weeks and 4 weeks of detraining (30 days). Results: Participants were classified as overweight, had a high percentage of body fat and irregular menstrual cycles (amenorrhea). The TIAI group showed improvements in the domains of functional capacity (P = 0.022; ES = 1.7), physical aspects (P = 0.027; ES = 1.7), general status (P = 0.021; ES = 3.1), anxiety (P = 0.025; ES = 1.0,) and depression (P = 0.031; ES = 1.7) (pre-post). We observed that improvements were not maintained after the 30-day detraining period in the quality of life domains. Conclusion: The TIAI program promoted an improvement in the quality of life and mental health in women with PCOS; additionally, it was observed that after 4 weeks of detraining there was a reduction in quality of life, however, the mental health domains (anxiety and depression) presented stability in the TIAI group, differents from the control group.
