Journal ArticleDOI
Sleep and muscle recovery: endocrinological and molecular basis for a new and promising hypothesis.
Murilo Dáttilo,Hanna Karen Moreira Antunes,Alessandra Medeiros,M. Mônico Neto,Helton de Sá Souza,Sergio Tufik,M.T. de Mello +6 more
TL;DR: It is hypothesized that sleep debt decreases the activity of protein synthesis pathways and increases theActivity of degradation pathways, favoring the loss of muscle mass and thus hindering muscle recovery after damage induced by exercise, injuries and certain conditions associated with muscle atrophy, such as sarcopenia and cachexia.
Journal ArticleDOI
Swimming training increases cardiac vagal activity and induces cardiac hypertrophy in rats
Alessandra Medeiros,Edilamar Menezes de Oliveira,R M Gianolla,Dulce Elena Casarini,Carlos Eduardo Negrão,Patricia Chakur Brum +5 more
TL;DR: The data suggest that RB induced by ST is mainly mediated parasympathetically and differs from other training modes, like running, that seems to mainly decrease intrinsic heart rate in rats.
Journal ArticleDOI
Heart failure with preserved ejection fraction induces molecular, mitochondrial, histological, and functional alterations in rat respiratory and limb skeletal muscle
T. Scott Bowen,Natale Rolim,Tina Fischer,Fredrik Hjulstad Bækkerud,Alessandra Medeiros,Sarah Werner,Eivind Brønstad,Øivind Rognmo,Norman Mangner,Axel Linke,Gerhard Schuler,Gustavo J. J. Silva,Ulrik Wisløff,Volker Adams +13 more
TL;DR: An animal model was used to elucidate potential molecular, mitochondrial, histological, and functional alterations induced by HFpEF in the diaphragm and soleus, while also determining the possible benefits associated with exercise training.
Journal ArticleDOI
Exercise training improves the net balance of cardiac Ca2+ handling protein expression in heart failure
Natale Pinheiro Lage Rolim,Alessandra Medeiros,Kaleizu T. Rosa,Katt Coelho Mattos,Maria Claudia Irigoyen,Eduardo M. Krieger,José Eduardo Krieger,Carlos Eduardo Negrão,Patricia Chakur Brum +8 more
TL;DR: Evidence is provided that Ca(2+) handling is impaired in this HF model and that overall VF improved upon ET, which was associated to changes in the net balance of cardiac Ca( 2+) handling proteins.
Journal ArticleDOI
Exercise training delays cardiac dysfunction and prevents calcium handling abnormalities in sympathetic hyperactivity-induced heart failure mice
Alessandra Medeiros,Natale Rolim,Rodrigo S. F. Oliveira,Kaleizu T. Rosa,Katt Coelho Mattos,Dulce Elena Casarini,Maria Claudia Irigoyen,Eduardo M. Krieger,José Eduardo Krieger,Carlos Eduardo Negrão,Patricia Chakur Brum +10 more
TL;DR: There is evidence that improved net balance of Ca(2+) handling proteins paralleled by a decreased sympathetic activity on ET are, at least in part, compensatory mechanisms against deteriorating ventricular function in HF.
