Reducing cardiovascular responses to stressors may help to reduce one's risk of developing cardiovascular disease. The present study examined the underlying hemodynamic changes that accompany heart rate (HR) response reduction to a stressor following HR feedback training. Twenty-five healthy college males were assigned to either a HR feedback training group (FB+) or a control group (FB--) and were presented with a videogame and mental arithmetic challenge, as HR, blood pressure, and impedance cardiography-derived measures were recorded. During the training sessions, the FB+ group received HR feedback and the FB-- group was not provided with HR feedback while playing the videogame. Results revealed that those in de FB+ group demonstrated significantly lower HR, systolic blood pressure, stroke volume, and peripheral-resistance responses to the post-training compared to the pre-training videogame. Overall, these results suggest that HR feedback training is an effective method for reducing cardiovascular responding to a stressor.
