Effect of exercise training and carvedilol treatment on cardiac function and st...
Medeiro,A.; Vanzelli,A.S.; Rosa,K.T.; Irigoyen,M.C.; Brum,P.C.The present investigation was undertaken to study the effect of β-blockers and exercise training on cardiac structure and function, respectively, as well as overall functional capacity in a genetic model of sympathetic hyperactivity-induced heart failure in mice (α2A/α2CArKO). α2A/α2CArKO and their wild-type controls were studied for 2 months, from 3 to 5 months of age. Mice were random...

The decreased oxygen uptake during progressive exercise in ischemia-induced hea...
Rolim,N.P.L.; Mattos,K.C.; Brum,P.C.; Baldo,M.V.C.; Middlekauff,H.R.; Negrão,C.E.We tested the hypothesis that the inability to increase cardiac output during exercise would explain the decreased rate of oxygen uptake (VO2) in recent onset, ischemia-induced heart failure rats. Nine normal control rats and 6 rats with ischemic heart failure were studied. Myocardial infarction was induced by coronary ligation. VO2 was measured during a ramp protocol test on a treadmill using a metabolic mask....

Loss of resting bradycardia with detraining is associated with intrinsic heart ...
Evangelista,F.S.; Martuchi,S.E.D.; Negrão,C.E.; Brum,P.C.The mechanisms underlying the loss of resting bradycardia with detraining were studied in rats. The relative contribution of autonomic and non-autonomic mechanisms was studied in 26 male Wistar rats (180-220 g) randomly assigned to four groups: sedentary (S, N = 6), trained (T, N = 8), detrained for 1 week (D1, N = 6), and detrained for 2 weeks (D2, N = 6). T, D1 and D2 were treadmill trained 5 days/week for 60...
Swimming training increases cardiac vagal activity and induces cardiac hypertro...
Medeiros,A.; Oliveira,E.M.; Gianolla,R.; Casarini,D.E.; Negrão,C.E.; Brum,P.C.The effect of swimming training (ST) on vagal and sympathetic cardiac effects was investigated in sedentary (S, N = 12) and trained (T, N = 12) male Wistar rats (200-220 g). ST consisted of 60-min swimming sessions 5 days/week for 8 weeks, with a 5% body weight load attached to the tail. The effect of the autonomic nervous system in generating training-induced resting bradycardia (RB) was examined indirectly af...
Duration-controlled swimming exercise training induces cardiac hypertrophy in mice
Evangelista,F.S.; Brum,P.C.; Krieger,J.E.Exercise training associated with robust conditioning can be useful for the study of molecular mechanisms underlying exercise-induced cardiac hypertrophy. A swimming apparatus is described to control training regimens in terms of duration, load, and frequency of exercise. Mice were submitted to 60- vs 90-min session/day, once vs twice a day, with 2 or 4% of the weight of the mouse or no workload attached to the...
