Key result
Attempting to alter HR produces greater HR changes than merely tracking it.
Why the study?
Does attempting to increase and decrease heart rate with or without visual feedback improve heart rate changes compared to merely tracking heart rate in college students?
Population
30 college students classified on the basis of cold-pressor blood pressure responses
Comparison
Attempting to increase and decrease heart rate… vs Merely tracking a visual analog display of heart…
Design
RCT, Randomly assigned to one of three treatment groups

Active HR modulation outperforms passive tracking with or without feedback; extends biofeedback research on voluntary autonomic control in young adults.

Does attempting to increase and decrease heart rate with or without visual feedback improve heart rate changes compared to merely tracking heart rate in college students?
Individuals can voluntarily control their heart rate with or without visual feedback, and high cold-pressor reactors demonstrate greater capacity for heart rate control.
Lott et al. (1978) reported an RCT. Heart rate control with or without visual feedback vs. Tracking visual analog display of heart rate was evaluated on Heart rate changes. Attempting to increase and decrease heart rate, with or without visual feedback, produced significantly greater heart rate changes than merely tracking heart rate.
