Purpose: To investigate the effects of a supervised aerobic exercise training intervention on health-related quality of life (HRQL), cardiorespiratory fitness, cardiometabolic profile, and affective response in overweight/obese women with polycystic ovary syndrome (PCOS). Methods: Twenty-seven overweight/obese inactive women with PCOS (body mass index, Q 25 kgIm j2 ; age 18 to 34 yr) were allocated into an exercise group (n = 14) and a control group (n = 13). Progressive aerobic exercise training was performed three times per week (~150 minIwk j1 ) over 16 wk. Cardiorespiratory fitness, HRQL, and cardiometabolic profile were evaluated before and after the intervention. Affective response (i.e., feeling of pleasure/displeasure) was evaluated during the exercise sessions. Results: The exercise group improved 21% T 12% of cardiorespiratory fitness (P G 0.001) and HRQL in the following domains: physical functioning, general health, and mental health (P G 0.05). Moreover, the exercise group decreased body mass index, waist circumference, systolic and diastolic blood pressure, and total cholesterol level (P G 0.05). The affective response varied from ''good'' to ''fairly good'' (i.e., positive affective response) in an exercise intensity-dependent manner during the exercise training sessions. Conclusions: Progressive aerobic exercise training improved HRQL, cardiorespiratory fitness, and cardiometabolic profile of overweight/obese women with PCOS. Moreover, the participants reported the exercise training sessions as pleasant over the intervention. These results reinforce the importance of supervised exercise training as a therapeutic approach for overweight/obese women with PCOS.

Purpose Acute reduction in blood pressure (BP) following an exercise session is evidenced in controlled settings with formal supervision in hypertensive older populations. This study investigated the effect of a self-selected exercise (SSE)-intensity session on ambulatory BP in hypertensive older women in a “real-world” setting. Methods Twenty inactive older women with hypertension (64.9±4.5 years) were included in this randomized, controlled, crossover trial. After baseline assessments, participants performed 30 minutes of an SSE-intensity session on an outdoor track and a control session, separated by 7-10 days. Heart rate (HR), rating of perceived exertion (RPE), and affective response were assessed. Ambulatory BP was monitored for 20 hours following both sessions. Paired t -tests and generalized estimation were used for data analysis. Results Participants exercised at 5.1±1.1 km/h, spent ~90% of the exercise time at moderate–vigorous intensity (≥40% of heart rate reserve). SSE-intensity session was reported as light (RPE 11.0±1.5) and pleasant (affect 3.4±1.2). SSE-intensity session elicited reductions in systolic BP in the first 6 hours postexercise (6.0 mmHg, CI 2.7–9.3 mmHg; P< 0.001). Average systolic BP in the 20-hour (−3.4 mmHg, CI −5.9 to −0.9 mmHg; P =0.010) and awake (−4.0 mmHg, CI −6.4 to −1.6 mmHg; P =0.003) periods were lower following SSE-intensity session compared to control session. No differences were observed in average systolic BP during asleep period and diastolic BP during the 20-hour awake and asleep periods between the SSE-intensity session and control session ( P >0.05). Conclusion An SSE-intensity session elicited a reduction in ambulatory systolic BP in inactive older women with hypertension during awake and 20-hour periods. Also, the SSE-intensity session was reported as light and pleasant.

A single session of low-volume high-intensity interval exercise reduces ambulatory blood pressure in normotensive men. J Strength Cond Res 31(8): 2263-2269, 2017-The magnitude and duration of postexercise hypotension (PEH) may provide valuable information on the efficacy of an exercise approach to blood pressure (BP) control. We investigated the acute effect of a time-efficient high-intensity interval exercise (HIIE) on ambulatory BP. Twenty-one normotensive men (23.6 ± 3.6 years) completed 2 experimental sessions in a randomized order: (a) control (no exercise) and (b) low-volume HIIE: 10 × 1 minute at 100% of maximal treadmill velocity interspersed with 1 minute of recovery. After each experimental session, an ambulatory BP monitoring was initiated. Paired sample t-test was used to compare BP averages for awake, asleep, and 20-hour periods between the control and the low-volume HIIE sessions. A 2-way repeated measures analysis of variance was used to analyze hourly BP after both experimental sessions. Blood pressure averages during the awake (systolic: 118 ± 6 vs. 122 ± 6 mm Hg; diastolic: 65 ± 7 vs. 67 ± 7 mm Hg) and 20-hour (systolic: 115 ± 7 vs. 118 ± 6 mm Hg; diastolic: 62 ± 7 vs. 64 ± 7 mm Hg) periods were lower after the low-volume HIIE compared with the control (p ≤ 0.05). Systolic and diastolic PEH presented medium (Cohen's d = 0.50-0.67) and small (Cohen's d = 0.29) effect sizes, respectively. Systolic PEH occurred in a greater magnitude during the first 5 hours (3-5 mm Hg). No changes were found in asleep BP (p > 0.05). In conclusion, a single session of low-volume HIIE reduced ambulatory BP in normotensive men. The PEH occurred mainly in systolic BP during the first 5 hours postexercise.

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.

Self-selected exercise intensity (SSE) is a simple approach to encourage an active lifestyle. This study aimed to investigate whether a SSE intensity session meet the recommended intensity for hypertension management (i.e. moderate-vigorous), and whether heart rate (HR), rating of perceived exertion (RPE) and affective responses are reproducible. Thirteen inactive hypertensive older women (age: 64.54 ± 4.16 years; blood pressure: 122.51/62.15 mmHg) performed two 30-minute SSE intensity sessions outdoors. HR reserve (HRR), RPE and affective responses were assessed. Paired t-test, intraclass correlation coefficient (ICC) and typical error (TE) were used for the analyzes. Participants exercised at moderate-vigorous intensity (≥ 40% of HRR). No differences were found for HRR (56.46 ± 8.01% vs. 59.08 ± 10.57%), RPE (11.26 ± 1.14 vs. 10.98 ± 1.52) and affective response (3.47 ± 1.13 vs. 3.38 ± 1.23) (p > 0.05). RPE showed excellent reliability (ICC = 0.82; 95%CI: 0.42; 0.94; p = 0.003). There was a poor reliability for HRR (ICC = 0.40; 95%CI: -0.97; 0.82; p = 0.193) and affective responses (ICC = 0.19; 95%CI: -2.10; 0.76; p = 0.369). TE between sessions for HRR, RPE, and affective response were 8.11 bpm, 0.75 and 1.11, respectively. In conclusion, inactive hypertensive older women seem to meet the recommended intensity for hypertension management when they exercise at a self-selected pace and report it as light-moderate and pleasant. Despite only RPE, but not HR and affective response, has shown good reproducibility, the results seem to support the use of SSE intensity as a simple approach to encourage an active lifestyle in this population.
