Present study tested the effects of discrete posttrial verbal feedback information on self control of an increase and a decrease in heart rate (HR). Sixteen volunteer male subjects were divided into two groups, in which they received either verbal feedback (VF) or no feedback (NF). All subjects were asked to increase and then decrease their HR relatively to their pretrial base HR levels, keeping their respiratory activities as much stable as possible during the tasks. Results showed that subjects in VF group achieved better HR control than ones in NF group, especially, in HR decrease sessions. Respiratory activities, however, could not account for these differences of HR. Therefore, it was suggested that the subject's internal strategy influenced the HR control. The relationship between HR control and verbal feedback information as the calibrator of the amount of HR changes was discussed.
