Biofeedback may transiently modulate exercise hemodynamics in healthy volunteers; hypothesis-generating and requires confirmation before any clinical consideration.
Does cardiovascular feedback (interbeat interval and pulse transit time) decrease cardiovascular activity during exercise in healthy volunteers?
Cardiovascular biofeedback using the product of interbeat interval and pulse transit time can modulate physiological responses during exercise, though the effect does not persist when feedback is removed.
Lo et al. (1984) studied this question.
