Cardiovascular Fitness Improves Cardiac Interoceptive Accuracy
Abstract
. Many of the sensory receptors encoding touch, temperature, pain, and visual or auditory cues are known; these exteroceptive receptors allow us to respond to external threats. The interoceptive sensory receptors that identify stimuli within the internal milieu, e.g. changes in our heart rate, gastric fullness, or breathing difficulty are not known. We postulated mechanosensitive piezo channels in the heart are responsible for cardiac interoception. We found that individuals with lower resting heart rates and resting rate‐pressure products, and higher heart rate variability and stroke volumes have greater interoceptive accuracy. These characteristics often result from exercise training.
