(Elsevier, 2016-01) Sá, Joceline Cassia Ferezini de; Costa, Eduardo Caldas; Silva, Ester da; Tamburús, Nayara Y.; Porta, Alberto; Medeiros, Leany F.; Lemos, Telma Maria Araujo Moura Lemos; Soares, Elvira M. M.; Azevedo, George Dantas de
Background: this study aimed to evaluate the effects of aerobic exercise on cardiac autonomic modulation in women with polycystic ovary syndrome (PCOS). Methods: thirty women with PCOS (25.8 ± 4.8 years old; body mass index, BMI ≥ 25 kg/m2) were divided into two groups; exercise group (n = 15) and control group (n = 15). R–R interval was recorded during 15-min at rest in the supine position. Heart rate variability (HRV) was analyzed by linear (rMSSD, SDNN, LF, HF, LFnu, HFnu, and LF/HF) and nonlinear methods (Shannon entropy, SE; symbolic analyses, 0 V%, 1 V%, 2LV%, and 2UV%) at baseline and after 16 weeks. The multivariate analysis of covariance was used to analyze the effects of exercise on HRV indexes, adjusted for changes in BMI, fasting insulin, and testosterone level. Results: the exercise group increased parasympathetic modulation (rMSSD, HF, HFnu, 2UV%; (p b 0.05)) and decreased sympathetic modulation (LF, LFnu, 0 V%; (p b 0.05)) independently of changes in BMI, fasting insulin, and testosterone level. Moreover, the exercise group decreased resting HR and systolic blood pressure (p b 0.05). All parameters remained unchanged in the control group. Conclusions: aerobic exercise increased vagal modulation and decreased sympathetic modulation in women with PCOS. This finding reinforces the recommendations for exercise during the clinical management of these patients
Aerobic training improves quality of life in women with Polycystic Ovary Syndrome
(Lippincott, Williams & Wilkins, 2018-07) Costa, Eduardo Caldas; Sá, Joceline Cássia Ferezini de; Stepto, Nigel Keith; Costa, Ingrid Bezerra Barbosa; Farias Junior, Luiz Fernando; Moreira, Simone da Nóbrega Tomaz; Soares, Elvira Maria Mafaldo; Lemos, Telma Maria Araujo Moura; Browne, Rodrigo Alberto Vieira; Azevedo, George Dantas de
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, ≥ 25 kg·m−2; 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 min·wk−1) 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% ± 12% of cardiorespiratory fitness (P < 0.001) and HRQL in the following domains: physical functioning, general health, and mental health (P < 0.05). Moreover, the exercise group decreased body mass index, waist circumference, systolic and diastolic blood pressure, and total cholesterol level (P < 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
Affect-regulated exercise: an alternative approach for lifestyle modification in overweight/obese women with polycystic ovary syndrome
(Taylor and Francis, 2015-09-25) Costa, Eduardo Caldas; Sá, Joceline Cássia Ferezini de; Costa, Ingrid Bezerra Barbosa; Meireles, Rodrigo da Silva Rosa Veleda; Lemos, Telma Maria Araújo Moura; Elsangedy, Hassan Mohamed; Krinski, Kleverton; Azevedo, George Dantas de
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
Qualidade de vida e aspectos psicossociais da síndrome dos ovários policísticos: um estudo quali-quantitativo
(Thieme Open, 2013-11) Moreira, Simone da Nóbrega Tomaz; Sá, Joceline Cássia Ferezini de; Costa, Eduardo Caldas; Azevedo, George Dantas de
Objetivos: avaliar a qualidade de vida das mulheres com síndrome dos ovários policísticos (SOP) e compreender a experiência vivida por essas mulheres diante dos sintomas que apresentam. Métodos: este estudo compreendeu duas abordagens metodológicas - quantitativa e qualitativa, de forma complementar. Foi avaliada a qualidade de vida de 213 mulheres (abordagem quantitativa) por meio do SF-36, sendo 109 com SOP (Grupo Caso: 26,8±5,4 anos) e 104 mulheres saudáveis (Grupo Controle: 23,9±6,7 anos). A análise estatística compreendeu a utilização dos testes t de Student e qui-quadrado, além dos testes de correlação de Pearson. O nível de significância adotado foi de 5%. Das mulheres do Grupo SOP, 15 participaram do estudo qualitativo, tendo sido entrevistadas mediante uso de roteiro semiestruturado. Os dados qualitativos foram analisados por meio da técnica análise de conteúdo temática categorial. Resultados: mulheres com SOP apresentaram comprometimento na qualidade de vida quando comparadas ao Grupo Controle (capacidade funcional: 76,5±20,5 e 84,6±15,9, respectivamente; aspectos físicos: 56,4±43,3 e 72,6±33,3; estado geral de saúde: 55,2±21,0 e 62,5±17,2; vitalidade: 49,6±21,3 e 55,3±21,3; aspectos sociais: 55,3±32,4 e 66,2±26,7; aspectos emocionais: 34,2±39,7 e 52,9±38,2; saúde mental: 50,6±22,8 e 59,2±20,2). Em relação aos dados qualitativos, a análise temática categorial aponta que sentimentos de "anormalidade", tristeza, medo e ansiedade estiveram associados aos principais sintomas da SOP: hirsutismo, irregularidade menstrual, infertilidade e obesidade. Esses sintomas repercutiram na vida social, na esfera profissional e no relacionamento conjugal dessas mulheres. Conclusão: a SOP compromete a qualidade de vida das mulheres, levando-as a se sentirem diferentes das outras mulheres. Por causa disso, a mulher com SOP não necessita apenas de tratamento médico para as repercussões reprodutivas, estéticas e metabólicas, mas de atendimento multiprofissional
Variabilidade da frequência cardíaca como método de avaliação do sistema nervoso autônomo na síndrome dos ovários policísticos
(Thieme Open, 2013-09) Sá, Joceline Cássia Ferezini de; Costa, Eduardo Caldas; Silva, Ester da; Azevedo, George Dantas de
A síndrome dos ovários policísticos (SOP) é uma condição endócrina que está associada a diversos fatores de risco cardiometabólico, tais como obesidade central, resistência à insulina, diabetes tipo 2, síndrome metabólica e hipertensão arterial. Esses fatores estão associados à hiperatividade adrenérgica, que é um importante fator prognóstico para o desenvolvimento de distúrbios cardiovasculares. Nos últimos anos, diante das alterações cardiometabólicas comuns na SOP, estudos têm investigado o controle autonômico cardíaco dessas pacientes, principalmente empregando-se a variabilidade da frequência cardíaca (VFC). Nesse sentido, nesta revisão, discorreremos sobre os achados recentes dos estudos que buscaram investigar a VFC em mulheres com SOP, assim como os métodos não invasivos de análise do controle autonômico a partir de índices básicos relacionados a essa metodologia de investigação
