Schematic representation of used animals in the present study. From 40 heart failure (HF) animals, n = 12 were assigned to sedentary (Sed) condition and n = 28 were assigned to exercise training (EX). From Sed animals, n = 6 were allocated to anesthetized experiments and n = 6 to non-anesthetized preparation. From HF + EX animals, n = 17 were classified as HF tolerant (HF + EX-T) animals and n = 11 were classified as HF intolerant (HF + EX-inT) rats. From total HF + EX-T animals, n = 7 were allocated to anesthetized experiments and n = 10 to non-anesthetized preparation (n = 4 to carotid body ablation and n = 6 to chemoreflex test at 8th weeks). From HF + EX-inT rats, n = 5 were allocated to anesthetized experiments and n = 6 to non-anesthetized preparation.
