Exercise training improves blood pressure reactivity to stress: a systematic review and meta-analysis.

Blood pressure (BP) reactivity to stress is associated with cardiovascular events and the incidence of hypertension, therefore, tolerance to stressors is important for better management of cardiovascular risks. Exercise training is among the strategies that have been investigated as blunting the peak response to stressors, however, its efficacy is poorly explored. The aim was to explore the effects of exercise training (at least four weeks) on BP responses to stressor tasks in adults. A systematic review was performed in five electronic databases (MEDLINE, LILACS, EMBASE, SPORTDiscus, and PsycInfo). Twenty-three studies and one conference abstract was included in the qualitative analysis, totaling 1121 individuals, and k = 17 and 695 individuals in the meta-analysis. Favorable results (random-effects) for exercise training were found, with attenuated peak responses in systolic (standardized mean difference (SMD) = -0.34 [-0.56; -0.11], representing average reductions of 2.5 ± 3.6 mmHg) and null effects on diastolic BP (SMD = -0.20 [-0.54; 0.14], representing average reductions of 2.0 ± 3.5 mmHg). The analysis removing outliers' studies improved the effects for diastolic (SMD = -0.21 [-0.38; -0.05]) but not systolic BP (SMD = -0.33 [-0.53; -0.13]). In conclusion, exercise training seems to lower stress-related BP reactivity, therefore has the potential to improve patients' ability to better respond to stressful situations.

Efeitos do treinamento resistido sobre indicadores de saúde de sobreviventes de câncer de mama / Effects of resistance training on health indicators in breast cancer survivors

O objetivo deste estudo foi investigar os efeitos do treinamento resistido sobre indicadores de saúde em sobreviventes de câncer de mama. Vinte e duas mulheres com histórico de mastectomia e linfadenectomia completaram 12 semanas de treinamento. Avaliações de força, índice de massa corporal, composição corporal, aspectos hematológicos, bioquímicos e de estabilidade de membrana eritrocitária foram realizadas antes e depois do período de treinamento. Em todos os exercícios, ocorreram ganhos significantes de força máxima e resistência de força. Além disso, houve diminuição do percentual de gordura corporal, aumento do percentual de massa magra, redução de eritrócitos, plaquetas e hemoglobina, bem como mudanças desejáveis para todas as variáveis de perfil lipídico. Em conjunto, esses achados destacam o impacto multidimensional do treinamento resistido sobre a saúde de sobreviventes de câncer de mama e revelam a necessidade de monitoramento constante desse público.

The present study aimed to investigate the effects of resistance training on health indicators in breast cancer survivors. Twenty-two women with a history of mastectomy and lymphadenectomy completed 12 weeks of training. Strength, body mass index, body composition, hematological, and biochemical aspects, and erythrocyte membrane stability were performed before and after the training. In all exercises, there were significant gains in maximal force and force endurance. Moreover, there was a decrease in body fat percentage, an increase in lean mass percentage, a reduction in erythrocytes, platelets, and hemoglobin, as well as desirable changes for all lipid profile variables. Altogether, these findings highlight the multidimensional impact of resistance training on the health of breast cancer survivors and reveal the need for constant monitoring of this public.

Comparison of Mat Pilates training-induced changes on climateric symptoms in hypertensive and normotensive postmenopausal women.

INTRODUCTION: Physical exercise has been used to improve the physiological, metabolic and psychological factors of women. OBJECTIVE: the aim of this study was to compare the 12-week Mat Pilates training-induced effect on climacteric symptoms in hypertensive and normotensive, non-obese postmenopausal women. METHODS: Forty-seven irregularly active, non-obese postmenopausal women participated in the study: 24 normotensive (58 ± 4 years) and 23 hypertensive (58 ± 4 years). They underwent 36 sessions of Mat Pilates in nonconsecutive days during 12 weeks. Climacteric symptoms were assessed by the Cervantes Scale (CER), Menopause Rating Scale (MRS) and Blatt-Kupperman Menopause Index (B-K). The unpaired t-test compared the clinical characteristics between the groups. For the analysis of the questionnaires, the Spearman correlation and Mann-Whitney U test were used to compare the means between the groups for non-parametric data. The generalized estimates equation (GEE) was used to compare the groups and time to score the three general and domain questionnaires. The significance level adopted was ɑ = 0.05. RESULTS: No difference in the Mat Pilates training-induced changes were found between normotensive and hypertensive women, but there was a significant reduction in the scores of the B-K and MRS and in the percentage of disappearance of symptoms by the B-K after training in both groups. Regarding the CER, there was a reduction in symptoms in the total value and the psychological, menopause and health domains. CONCLUSION: The presence of hypertension did not change the 12-week Mat Pilates training-induced benefits on the climacteric symptoms of non-obese postmenopausal women.

Redox Status of Postmenopausal Women with Single or Multiple Cardiometabolic Diseases Has a Similar Response to Mat Pilates Training.

Postmenopausal women have a high prevalence of cardiometabolic diseases and that may associate with higher oxidative stress. Exercise can contribute to the treatment of such diseases, but some modalities, such as Mat Pilates, need to be further studied in terms of their physiological responses. Our aim was to investigate the effects of 12 weeks of Mat Pilates on redox status in postmenopausal women with one or multiple comorbidities of cardiometabolic diseases. Forty-four postmenopausal women were divided into two groups: SINGLE, composed of women with one cardiometabolic disease (n = 20) and MULT, with multimorbidity (n = 24). Mat Pilates training was conducted three times a week for 12 weeks, and each session lasted 50 min. Plasma samples were collected before and after training to analyze the following redox markers: superoxide dismutase, catalase, glutathione peroxidase, total antioxidant capacity due to ferric-reducing antioxidant power (FRAP), reduced glutathione (GSH), uric acid, and carbonyl protein. ANCOVA showed interaction effects in FRAP (p = 0.014). Both groups had reduced levels of catalase (p = 0.240) and GSH (p = 0.309), and increased levels of carbonyl protein (p = 0.053) after intervention. In conclusion, the redox status of postmenopausal women shows no changes mediated by Mat Pilates training between SINGLE and MULT, except for greater reductions of FRAP in SINGLE.

Does Obesity Aggravate Climacteric Symptoms in Postmenopausal Women?

OBJECTIVE: To determine if there is a correlation between body mass index (BMI) and climacteric symptoms in postmenopausal women. METHODS: The study sample was composed of 109 postmenopausal women with a mean age of 57 ± 8 years, mean body mass index (BMI) of 30 ± 6 kg/m2, and 8 ± 8 years after menopause. For the assessment of the climacteric symptoms, the Blatt-Kupperman Index (BKI), the Menopause Rating Scale (MRS), and the Cervantes Scale (CS) were used. Data analysis was performed through the Chi-squared test, analysis of variance (ANOVA) with the Bonferroni post hoc test, and multiple linear regression. The level of significance adopted was of p < 0.05. The statistical analyses were performed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, United States) software, version 26.0. RESULTS: The multiple linear regression showed a positive association (p < 0.01) between BMI values and menopause symptoms when adjusted for age and time after menopause in the 3 questionnaires used (BKI: B = 0.432; CS: B = 304; and MRS: B = 302). Regarding symptom scores, the obese women had higher mean scores (p < 0.05) when compared to eutrophic women (BKI = 28 ± 10 and 20 ± 10; and MRS = 20 ± 10 and 13 ± 7, respectively). In the Chi-squared analysis, 28% of obese women had severe symptoms and 46% had moderate symptoms, while only 1% and 46% of eutrophic women had these same symptoms. CONCLUSION: There is an association between BMI and climacteric symptoms, and overweight or obese women have more intense and moderate symptoms than eutrophic women.

OBJETIVO: Verificar se há correlação entre o índice de massa corporal e os sintomas do climatério em mulheres na pós-menopausa. MéTODOS: Participaram do estudo 109 mulheres na pós-menopausa, com idade média de 57 ± 8 anos, índice de massa corporal (IMC) médio de 30 ± 6 kg/m2 e 8 ± 8 anos após a menopausa. Para a avaliação dos sintomas climatéricos, foram utilizados os questionários específicos para essa população: Índice de Kupperman-Blatt (IKB), Menopause Rating Scale (MRS), e Escala de Cervantes (EC). A análise dos dados foi realizada por meio do teste do chi-quadrado, análise de variância (analysis of variance, ANOVA, em inglês) com o teste post hoc de Bonferroni e regressão linear múltipla. O nível de significância adotado foi p < 0,05. Todas as análises estatísticas foram realizadas no programa Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, Estados Unidos), versão 26.0. RESULTADOS: A regressão linear múltipla mostrou associação positiva (p < 0,01) entre os valores do IMC e os sintomas do climatério quando ajustados pela idade e pelo tempo após a menopausa nos 3 questionários utilizados (IKB: B = 0,432; CE: B = 304; e MRS: B = 302). Quanto às pontuações dos sintomas, as mulheres com obesidade apresentaram médias maiores (p < 0,05) quando comparadas às mulheres eutróficas (IKB = 28 ± 10 e 20 ± 10; e MRS = 20 ± 10 e 13 ± 7). Na análise pelo chi-quadrado 28% das mulheres obesas apresentaram sintomas graves, e 46%, moderados, ao passo que apenas 1% e 46% das eutrópicas apresentavam esses mesmos sintomas. CONCLUSãO: Há uma associação entre IMC e sintomas climatéricos, e mulheres com sobrepeso ou obesidade apresentam sintomas mais intensos e moderados do que mulheres eutróficas.

Mat Pilates training reduces blood pressure in both well-controlled hypertensive and normotensive postmenopausal women: a controlled clinical trial study.

AIM: The aim of this study was to compare the Mat Pilates training-induced responses in resting and ambulatory blood pressure monitoring (ABPM), blood pressure variability (BPV), and heart rate variability (HRV) in well-controlled hypertensive and normotensive postmenopausal women. METHODS: Forty-seven postmenopausal women were allocated in well-controlled hypertensive (HT) and normotensive (NT) groups. The exercise program was performed three times a week for 12 weeks. Before and after the intervention resting, blood pressure (BP), ABPM, HRV, and BPV were analyzed. RESULTS: Student's t-test showed no difference in baseline anthropometric and resting BP values between groups. The generalized estimation equation (GEE) showed no interactions (group*time), but time (p < .05) reductions in resting systolic, diastolic and mean BP after training in both groups. Sleep ambulatory systolic, diastolic and mean BP were higher overall in the HT group (p < .05 in group effect). We also found a time effect (p < .05) with significant increases in BPV in the mean diurnal and nocturnal deviations weighted for the duration of the daytime and nighttime interval (SDdn) in systolic, diastolic and mean BP, and in the average real variability (ARV) in diastolic and mean in both groups. In addition, HRV increases (p < .05 in time effect) through the percentage of pairs of adjacent RR intervals with a difference of at least 50 ms (pNN50) after training in both groups. CONCLUSION: Both normotensive and well-controlled hypertensive postmenopausal women may have similar Mat Pilates exercise training-induced responses in ambulatory BP, BPV and HRV.

Mat Pilates training and blood pressure reactivity responses to psychological stress: comparison between normotensive and hypertensive postmenopausal women.

OBJECTIVES: The aim of this study is to compare resting blood pressure and blood pressure reactivity responses to psychological stress in normotensive and hypertensive postmenopausal women after 12 weeks of Mat Pilates training. METHODS: Twenty-three hypertensive and 24 normotensive postmenopausal women, performed Mat Pilates training 3× a week for 12 weeks. Before and after the intervention, resting blood pressure, heart rate, and blood pressure reactivity to psychological stress through the electronic version of Stroop test protocol (3 minutes) were measured. We calculated the variation (Δ) of blood pressure (peak of blood pressure during the Stroop stress test minus resting blood pressure before test). RESULTS: The two-way ANOVA showed that the Δ of systolic blood pressure, diastolic blood pressure, and the mean blood pressure was reduced ( P < 0.05) after training only in the hypertensive. The resting systolic, diastolic, and mean blood pressures decreased by ( P < 0.05) over time in both groups with no interaction or difference. CONCLUSION: Mat Pilates was able to reduce resting blood pressure in both hypertensive and normotensive, and blood pressure reactivity after psychological stress in hypertensive but not in normotensive postmenopausal women.

Effects of light-emitting diode therapy on cardiovascular and salivary nitrite responses in postmenopausal women submitted to a single bout of high-intensity interval training.

The aim of the present study was to analyze the effects of light-emitting diode therapy (LEDT) on cardiovascular effort during a single bout of high-intensity interval training (HIIT) and on blood pressure (BP), salivary nitrite, and heart rate variability (HRV) responses after the exercise session in postmenopausal women. Sixteen postmenopausal women between 50 and 70 years of age participated in the present study. The intervention comprised two sessions: placebo plus HIIT and LEDT plus HIIT, with a 14-day interval between sessions. The oxygen uptake (VO2), heart rate (HR), and rating of perceived exertion (RPE) were monitored throughout the HIIT sessions. Salivary samples were taken before, immediately post, and 30' and 60' post-HIIT sessions for nitric oxide (NO) analysis. In addition, HR and BP were checked before, 15 min, 30 min, 45 min, and 60 min post-HIIT sessions. HR data were used to calculate the HRV indices. Cardiovascular parameters during HIIT and BP, HRV, and NO responses were not different between placebo and LEDT conditions (p > 0.05). BP responses increased after compared to pre-exercise (p < 0.01). HRV was impaired post- compared to pre-exercise (p < 0.05). LEDT did not improve physiological performance during HIIT and did not accelerate the recovery of BP and autonomic modulation or change the NO release after exercise in postmenopausal women.

Physical activity as a protective factor for climacteric symptoms / Atividade física como fator de proteção para sintomas do climatério

The aim of this study was to investigate the association between the symptoms and quality of life (QOL) in climacteric with the level and intensity of physical activity (PA), body mass index (BMI), use of menopausal hormone therapy (MHT) and education level. The study was carried out with 641 climacteric women, 56 ± 6 years of age, who completed four questionnaires: Kupperman-Blatt Index (KBI) and Menopause Rating Scale (MRS) to assess climacteric symptoms, the Cervantes Scale (CS) for assess QOL, the International Physical Activity Questionnaire ­ short version (IPAQ) to assess PA and questions about weight, height, use of MHT and level of education. Spearman's correlation was performed in SPSS 26 software and binary logistic regression in Stata 14.0 software, adopting a p < 0.05. Having a university education (KBI = 44%), practicing more than 150 minutes of total PA/week (KBI = 48%) and more than 10 minutes of vigorous PA/week (KBI = 36%) were protective factors for vasomotor symptoms, weakness, headache, paresthesia, vertigo, arthralgia or myalgia, palpitations, tingling and symptoms related to moderate/high mood. Having a normal BMI (CS =4 3%), university level of education (CS = 46%) and practicing more than 150 minutes of total PA/week (CS = 61%) are protective factors for better QOL. For psychological, somatic and urogen-ital symptoms, assessed by MRS, there was no association with exposure factors. Thus, reaching the PA recommendations, having a university education level and having a normal BMI are protective factors for moderate and severe climacteric symptoms and QOL

O objetivo desta pesquisa foi investigar a associação entre os sintomas e qualidade de vida (QDV ) no cli-matério com o nível e intensidade da atividade física (AF), índice de massa corporal (IMC), utilização de terapia hormonal da menopausa (THM) e nível de escolaridade.O estudo foi realizado com 641 mulheres climatéricas, com 56 ± 6 anos de idade, que preencheram o Índice de Kupperman-Blatt (IKB) e Menopause Rating Scale (MRS) para avaliar os sintomas do climatério, a Escala de Cervantes (EC) para avaliar a QDV, o Questionário Internacional de Atividade Física ­ versão curta (IPAQ) para avaliar AF e perguntas sobre peso, estatura, uso de THM e nível de escolaridade. Foi realizado a correlação de Spearman no software SPSS 26 e a regressão logística binária no software Stata 14.0, adotando-se um p < 0,05. Ter nível de escola-ridade universitário (IKB = 44%), praticar mais de 150 minutos de AF total/semana (IKB = 48%) e mais de 10 minutos de AF vigorosa/semana (IKB = 36%), são fatores de proteção para sintomas vasomotores, fraque-za, cefaleia, parestesia, vertigem, artralgia ou mialgia, palpitações, formigamentos e sintomas relacionados ao humor moderado/acentuado. Ter IMC normal (EC = 43%), nível de escolaridade universitário (EC = 46%) e praticar mais de 150 minutos de AF total/semana (EC = 61%), são fatores protetores de proteção para melhor QDV. Para sintomas psicológicos, somáticos e urogenital, avaliados pelo MRS, não houve associação com os fatores de exposição.Assim, atingir as recomendações de AF, ter nível de escolaridade universitário e o IMC normal são fatores de proteção para sintomas climatéricos moderados e acentuados e QDV

Blood Pressure and Heart Rate Variability Responses to High-Intensity Interval Training in Untrained Postmenopausal Women.

Purpose: The aim of this study was to analyze the blood pressure (BP) and heart rate variability (HRV) responses in untrained postmenopausal women submitted to acute single sessions of high-intensity interval training (HIT). Method: Sixteen postmenopausal women (59.9 ± 5.6 years, 26.7 ± 3.0 kg/m2) participated in a random order of two acute sessions in a balanced crossover format: control without exercise in sitting position or HIT session. BP and heart rate (HR) were recorded before and during 60 min following the sessions. Results: Diastolic (DBP), mean BP (MBP), and double product (DPO) showed interaction (p < .01). DBP, MBP, and DPO increased (p < .01) after HIT but not after the control session. The area under the curve (AUC) of DBP (p = .02) and DPO (p < .01) were different between conditions. Time and frequency indices of HRV presented interaction (p < .05) which impaired these indices post-HIT, but not post-control. The AUC of time and frequency HRV indices were different between conditions. Conclusions: A single session of HIT may increase BP and cardiac stress and cause perturbation of the autonomic function in untrained postmenopausal women.

Effect of the execution order from concurrent exercise session on blood pressure responses in hypertensive older men

Abstract Aim: To compare blood pressure (BP) responses among the different orders of execution of concurrent exercise (CE) sessions in controlled hypertensive older men. Methods: Fifteen older men (64 ± 5 years) participated in three randomized crossover sessions: control session (C), CE in aerobic-resistance order (AR), and resistance-aerobic order (RA). The CE was performed for 1 h, in which 30 min were for the resistance exercise with 5 exercises at 70% of 1RM and 30 min for the aerobic exercise on a treadmill with intensity corresponding to the first ventilatory threshold. Clinical systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) were measured at rest and over 2 h and 24 h after the session. For analysis, the Generalized Estimating Equations (GEE) test was used with Bonferroni's complimentary test (α = 0.05). Results: The SBP decreased by 30 min after AR, while after RA we obtained reductions during 1 h after a session concerning rest. Between sessions, we found lower values in both CE compared to the C at 30 min, 45 min, and 90 min. In the RA there was a lower pressure in relation to the C at minute 60. The DBP reduced 30 min after the AR regarding the pre-session, however with no difference between sessions. The MBP was lower in relation to 30 min rest after AR. Among sessions, a pressure drop was observed in the AR compared to the C at 30 min and 45 min. Conclusion: We can conclude that the CE was effective in generating post-exercise hypotension regardless of the order in controlled hypertensive older men.

The execution order of the concurrent training and its effects on static and dynamic balance, and muscle strength of elderly people

Abstract Aim: Assess the effect of the performance order in the Concurrent Training (CT), Aerobic-Strength (AS), and Strength-Aerobic (SA), in the static balance, dynamic balance, and muscle strength in elderly people. Methods: The study involved 38 elderly people (men and women) aged 60 to 75 years old, divided into SA (n = 19) and AS (n = 19). Within 12 weeks, the aerobic training consisted of walking with intensity prescribed by the Borg's Rating of Perceived Exertion (6-20) and the strength training consisted of six exercises, with intensity controlled by Repetition Maximum training zones. Static balance (plantar pressure center area and displacement in bipedal support with eyes closed and open), dynamic balance (Timed Up and Go and Tandem Gait), and maximum dynamic strength of knee extension and bench press have been evaluated. For data analysis, Generalized Estimating Equations with Bonferroni's complimentary test have been used (α = 0.05). Results: For static and dynamic balance there hasn't been an effect on the 12 weeks of combined training, regardless of the performance order. Both groups maintained the balance variables within the intervention period. When it comes to strength, there has been a noticeable improvement in lower limbs (SA: 16%; AS: 11%; p < 0,001) and upper (SA: 22.0%; AS: 8.7%; p < 0.001), without any differences between the groups. Conclusion: So there is no difference between the order of performance of the CT in the variables of static and dynamic balance and strength of upper and lower limbs. Furthermore, after training, there have been significant improvements in the variables of strength and maintenance of static and dynamic balance.

AIMS: The present study aimed to verify the effects of resistance training (RT) and successive detraining on body composition, muscle strength and lipid profile as primary outcome, and the oxidative stress and inflammatory markers as second outcome of postmenopausal Breast Cancer (BC) survivors undergoing tamoxifen (TA). MAIN METHODS: Fourteen postmenopausal BC survivors underwent 12 weeks of resistance exercise training and subsequently 12 weeks of detraining. Anthropometric parameters, lipid profile, muscle strength, inflammatory cytokines and the oxidative stress markers, were assessed before, after the training period and after detraining period. KEY FINDINGS: One-way ANOVA showed that fat mass decrease (39.4 ± 6.9 to 37.7 ± 6.8%) and free-fat mass increase (39.3 ± 4.9 to 40.3 ± 5.6%) after RT. Muscle strength increased in response to training but decreased after the detraining period. Triglycerides (156 ± 45 to 123 ± 43 mg/dL) and total cholesterol (202 ± 13 to 186 ± 16 mg/dL) decreased after the RT and HDL-cholesterol (47 ± 9 to 56 ± 9 mg/dL) increased after RT and remained higher (53 ± 10 mg/dL) than after detraining. IL-6 increases (24.65 ± 10.85 to 41.42 ± 22.88 pg/mL) and IL-17 (2.42 ± 0.32 to 1.69 ± 0.19 pg/mL), TBARS (1.91 ± 0.19 to 1.03 ± 0.1 µmol/L), SOD (24.65 ± 10.85 to 41.42 ± 22.88 U/gHb) and Catalase activity (445.9 ± 113.0 to 345.8 ± 81.7 k/gHb·s) reduced after RT and remained lower after detraining. SIGNIFICANCE: Resistance exercise training improves health markers of BC survivors undergoing TA and detraining are not sufficient to reverse the positive effects in oxidative stress markers.

Parasympathetic modulation during sleep time is reduced after maximal exercise, correlated with aerobic fitness in young women / A modulação parassimpática durante o sono é reduzida após o exercício máximo e está correlacionada com a aptidão aeróbia em mulheres jovens

abstract It is known that cardiovascular risk is increased during exercise and recovery. Thus, it is necessary to assess all the risk associated with exercise to minimize the possibility of cardiovascular events. The aim of this study was to verify whether a maximal exercise alters ambulatory cardiac autonomic modulation in untrained women and whether aerobic fitness is correlated to cardiac autonomic modulation. Twelve women (25.35 ± 5.44 years) were outfitted with the Holter monitor on an experimental (after maximum exercise) and a control day to heart rate variability (HRV) evaluation. Maximal exercise increased 24 h heart rate (82 ± 14 vs 77 ± 11 bpm; p = 0.04) and during sleep time (72 ± 14 vs. 65 ± 9 bpm; p = 0.01), reduced parasympathetic modulation (HF - n.u. 49.96 ± 11.56 vs 42.10 ± 14.98; p = 0.04), and increased low-frequency/high-frequency ratio (2.88 ± 3.24 vs 1.31 ± 0.60; p = 0.03) during sleep time compared to the control day. Aerobic fitness was correlated positively with LF, HF, and HF (n.u.) indices (r = 0.61 to 0.73, p < 0.05) and correlated negatively with LF (n.u.) and LF/HF ratio (Rho = - 0.57 to - 0.69; p < 0.05). Maximal exercise alters parasympathetic modulation during sleep time in untrained women. Ambulatory cardiac autonomic modulation after exercise is related to aerobic fitness.

resumo Sabe-se que o risco cardiovascular aumenta durante o exercício e sua recuperação. Assim, é necessário avaliar todo o risco associado ao exercício para minimizar a chance de eventos cardiovasculares. Objetivou-se verificar se um exercício máximo altera a modulação autonômica cardíaca ambulatorial em mulheres não treinadas e se a aptidão aeróbia está correlacionada à modulação autonômica cardíaca. Doze mulheres (25,35 ± 5,44 anos) foram equipadas com monitor Holter em um dia experimental (após exercício máximo) e dia controle para avaliação da variabilidade da frequência cardíaca (VFC). O exercício máximo aumentou a frequência cardíaca de 24 h (82 ± 14 vs 77 ± 11 bpm; p = 0,04) e durante o sono (72 ± 14 vs 65 ± 9 bpm; p = 0,01), bem como reduziu a modulação parassimpática (HF - nu 49,96 ± 11,56 vs 42,10 ± 14,98; p = 0,04) e aumentou a razão de baixa frequência / alta frequência - LF/HF (2,88 ± 3,24 vs 1,31 ± 0,60; p = 0,03) durante o período do sono em comparação com o dia controle. A aptidão aeróbia foi correlacionada positivamente com os índices LF, HF e HF (nu) (r = 0,61 a 0,73, p <0,05) e negativamente correlacionada com LF (nu) e razão LF / HF (Rho = - 0,57 a - 0,69; p <0,05). O exercício máximo altera a modulação parassimpática durante o sono em mulheres não treinadas. A modulação autonômica cardíaca ambulatorial após o exercício foi correlacionada com a aptidão aeróbia.

Acute and chronic effects of combined exercise on ambulatory blood pressure and its variability in hypertensive postmenopausal women.

The aim of this study was to investigate the acute and chronic effects, and their correlation, after combined aerobic and resistance exercises in blood pressure (BP) and its variability (BPV) in hypertensive postmenopausal women. Fourteen hypertensive postmenopausal women monitored BP at rest and during 24 h by ambulatory BP monitoring in a control day without exercise performance a pretraining (baseline), after an acute exercise session (acute), and after a chronic exercise training for 10 weeks (chronic). After exercise training, systolic BP (SBP, Δ = -150 mmHg.24 h), diastolic BP (DBP, Δ = -96 mmHg.24 h), and mean BP (MBP, Δ = -95 mmHg.24 h) area under the curve were smaller than baseline measurements (P < 0.05) with no difference between acute and baseline measurements. The SBP (ΔSD24 = -2, ΔSDdn = -1.7, and ΔARV24 = -1.9 mmHg), DBP (ΔSD24 = -0.9, ΔSDdn = -0.8, and ΔARV24 = -0.9 mmHg), and MBP (ΔSD24 = -1.5, ΔSDdn = -1.3, and ΔARV24 = -1.2 mmHg) variability reduced in acute session in relation to baseline, with no chronic effects. There are moderate correlations between acute and chronic responses in wake SBP, sleep DBP, and SD24. In conclusion, combined exercise reduces ambulatory BP chronically but not acutely. In contrast, BPV decreases after an acute session but not chronically. Awake SBP, sleep DBP, and SD24indices are promising candidates to predict individual cardiovascular responses to exercise.

Ambulatory blood pressure variability and combined exercise training: comparison between hypertensive and normotensive postmenopausal women.

AIM: The aim of the study was to verify the effects of moderate combined aerobic and resistance exercises training in ambulatory blood pressure (ABPM) and its variability in hypertensive and normotensive postmenopausal women. METHODS: Twenty-six participants were divided into two groups: hypertensive (HT = 13) and normotensive (NT = 13). They performed 30 sessions of combined exercises (aerobic and resistance exercises at same session) over 10 weeks. We evaluated: resting BP and 24-h ABPM with systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), and heart rate (HR). To evaluate blood pressure variability (BPV), the following were considered: 24-h SD (SD24), the mean diurnal and nocturnal deviations (SDdn), average real variability (ARV24). RESULTS: The two-way analysis of variance showed no difference in ABPM nor BPV responses after training between groups. Both HT and NT groups had similar BP reductions in 24-h DBP (P < 0.01; ΔNT = -3.1 ± 1.1, ΔHT = -1.8 ± 1.2 mmHg), 24-h area under the curve of DBP (P = 0.01; ΔNT = -73±105, ΔHT = -44 ± 115 mmHg), and wake DBP (P < 0.01; ΔNT = -3.4 ± 1.2, ΔHT = -1.8 ± 1.3 mmHg), without differences in BPV responses. Moreover, HT women had higher overall SBP SDdn (P = 0.01), SBP ARV (P = 0.02), and MBP ARV (P < 0.01) than NT women. CONCLUSION: Ten-week combined exercise training resulted in similar BP reductions in hypertensive and normotensive postmenopausal women, but not in BPV responses.

Isoflavone does not promote additional effects on heart rate variability of postmenopausal women performing combined exercise training: a clinical, controlled, randomized, double-blind study.

The aim of the study was to investigate the effects of ingesting isoflavones associated with combined aerobic and resistance exercise training on heart rate variability (HRV) indices in postmenopausal women. Twenty-eight healthy postmenopausal women performed 10 weeks of combined exercise training associated with isoflavone (n = 16) or placebo (n = 12) supplementation. The RR intervals (RRi) were collected for 20 min using a heart rate monitor. Analysis of HRV was performed in time (mean squared difference of successive RRi (RMSSD), standard deviation of all normal RRi (SDNN), and percentage of adjacent RRi differing by more than 50 ms (pNN50)), frequency (low-frequency percentage (LF%), high-frequency percentage (HF%), and low-/high-frequency ratio (LF/HF)), and nonlinear domains (standard deviation of the instantaneous variability of the beat-to-beat interval (SD1), long-term variability of the continuous RRi (SD2), and their ratio (SD2/SD1)). Student's t test did not show differences between groups in any general baseline characteristic variables. The results of the generalized estimating equation tests did not demonstrate interaction or group effects for any HRV indices. However, the results reported time effects for mean RR (p < 0.001), RMSSD (p = 0.044), and SD1 (p = 0.044), with increases in these indices in response to exercise training. There were no time effects for LF%, HF%, LF/HF, SDNN, pNN50, SD2, or SD2/SD1. In conclusion, isoflavone supplementation did not promote additional effects on HRV indices of postmenopausal women subjected to 10 weeks of combined exercise training. Novelty Combined training improves heart rate variability in postmenopausal women. Isoflavone supplementation did not promote additional effects on heart rate variability in postmenopausal women.
