ResumoABSTRACT The effects of verbal instructions, interbeat interval feedback, and feedback of the product of interbeat interval and pulse transit time in enabling subjects to decrease cardiovascular activity during exercise were studied in 36 healthy volunteers cycling a modified bicycle ergometer. During the 4 training sessions subjects given product feedback showed smaller decreases in interbeat interval and pulse transit time during exercise than did subjects receiving only verbal instructions. Subjects receiving interbeat interval feedback fell between the other two conditions. On the fifth session, during which feedback was not provided, no differences were found among the three conditions. The use of feedback of the product of interbeat interval and pulse transit time to control the sympathetic input to the heart and in the treatment of angina pectoris is discussed.
