Having the Heart to Exercise Control: Cardiac Interoception Influences Self-Paced Exercise Regulation.

ABSTRACT: The aim of this study was to examine the role of cardiac interoception on self-regulated (Experiment 1) and externally prescribed (Experiment 2) exercises. Cardiac interoception was assessed using heartbeat tracking and discrimination tasks in both experiments. Based on heartbeat discrimination performance, participants were partitioned into groups demonstrating GOOD and POOR cardiac interoceptive accuracy. In Experiment 1, 20 participants completed two self-regulated 20-min cycling tasks at two intensities (light rated physical exertion [RPE on Borg Scale = 10] vs. hard-to-very hard, RPE = 16). During self-regulated exercise, the POOR cardiac interoception group showed lower differences in their exercise work rates and physiological responses between light and hard-to-very hard intensity
