Análise dos índices espectrais da variabilidade da freqüência cardíaca em homens de meia idade e mulheres na pós-menopausa

Abstract: Objetivo: Analisar e comparar a variabilidade da freqüência cardíaca (VFC), em repouso, de homens e mulheres de meia-idade. Métodos: Foram estudados 10 homens (54 ± 3,2 anos) e 14 mulheres na pós-menopausa (56 ± 2,6 anos) que não faziam uso de terapia hormonal. A freqüência cardíaca (FC) e os intervalos R-R foram obtidos a partir do eletrocardiograma, batimento a batimento, durante 8 minutos em repouso, nas posições supina e sentada. A VFC foi analisada no domínio da freqüência, usando a transformada rápida de… Show more

“…Functional training has been prepared from the imitation of everyday gestures and activities (e.g. bathing, preparing meals, climbing stairs), and it is based on carrying out exercises aimed at improving control, stability and motor coordination . Therefore, functional training uses unstable surfaces to recruit multiple muscle groups, and thus requires greater activation of the abdominal and back muscles, and provides various neuromuscular adaptations …”

“…Studies involving models of linear analysis showed that women presented higher HRV in the supine position than men of a similar age, indicating that the female population has a higher cardiac vagal modulation and a lower cardiac sympathetic modulation (4)(5)(6)(7)(8)(9). The aging process also interferes with cardiac autonomic modulation, and a decrease in HRV has been observed with aging (3,(10)(11)(12)(13)(14).…”

“…quando comparada à posição sentada de jovens saudáveis (32,35). No que se refere à faixa etária, os estudos apontam para uma redução progressiva da VFC com o incremento da idade (33,35,36) e, em relação à idade e ao gênero, ocorre maior atividade parassimpática e menor atividade simpática em mulheres pós-menopausa quando comparadas a homens de faixa etária semelhante (34). Em relação ao ritmo circadiano, foi demonstrada maior modulação vagal no período da manhã em mulheres saudáveis (38).…”
