Journal ArticleDOI
Effects of age and physical activity on the autonomic control of heart rate in healthy men.

TL;DR: It is suggested that aging reduces HR variability, however, regular physical activity positively affects vagal activity on the heart and consequently attenuates the effects of aging in the autonomic control of HR.
Journal ArticleDOI
Aging reduces complexity of heart rate variability assessed by conditional entropy and symbolic analysis
Anielle Cristhine de Medeiros Takahashi,Alberto Porta,Ruth Caldeira de Melo,Ruth Caldeira de Melo,Robison José Quitério,Robison José Quitério,Ester da Silva,Ester da Silva,Audrey Borghi-Silva,Eleonora Tobaldini,Nicola Montano,A. M. Catai +11 more
TL;DR: In the aging process, the distributions of patterns (SE) remain similar to young subjects, however, the regularity is significantly different; the patterns are more repetitive in the old group (a decrease of CI and NCI).
Journal ArticleDOI
High eccentric strength training reduces heart rate variability in healthy older men
Ruth Caldeira de Melo,Robison José Quitério,A. C. M. Takahashi,Ester da Silva,Luiz Eduardo Barreto Martins,A. M. Catai +5 more
TL;DR: The results of the present investigation suggest that high eccentric strength training performed by healthy older men increases peak torque and reduces systolic blood pressure, however, an autonomic imbalance towards sympathetic modulation predominance was induced by an unknown mechanism.
Journal ArticleDOI
Impact of gender on benefits of exercise training on sympathetic nerve activity and muscle blood flow in heart failure
Ligia M. Antunes-Correa,Ruth Caldeira de Melo,Thais S. Nobre,Linda M. Ueno,Fábio Gazelato de Mello Franco,Ana Maria F. W. Braga,Maria Urbana P. B. Rondon,Patricia Chakur Brum,Antonio Carlos Pereira Barretto,Holly R. Middlekauff,Carlos Eduardo Negrão +10 more
TL;DR: The effects of exercise training on neurovascular control and functional capacity in men and women with chronic heart failure are compared.
Journal ArticleDOI
Exercise training improves neurovascular control and functional capacity in heart failure patients regardless of age
Ligia M. Antunes-Correa,Bianca Y Kanamura,Ruth Caldeira de Melo,Thais S. Nobre,Linda M. Ueno,Fábio Gazelato de Mello Franco,Fabiana Roveda,Ana Maria F. W. Braga,Maria Urbana P. B. Rondon,Patricia Chakur Brum,Antonio Carlos Pereira Barretto,Holly R. Middlekauff,Carlos Eduardo Negrão +12 more
TL;DR: Exercise training significantly and similarly increased FBF and peak VO2 in middle-aged and older heart failure patients and reduced MSNA and forearm vascular resistance in these patients, and no significant changes were found in untrained patients.
