The other mechanism is based on the effects of peptides produced by cardiomyocytes and endothelial cells on pacemaker cells of the sinoatrial node. The mechanisms responsible for exercise-induced reductions in baseline heart rate (HR), known as training bradycardia, remain controversial. Univ., 1995. 73, part 1, p. 197. 45, p. 621.

Thus, increased venous return stretches the heart and causes increased force of contraction (and a moderate increase in heart rate), resulting in a corresponding increase in cardiac output.
