The present study was designed to investigate the effect of using respiration as a strategy on voluntary control of the heart rate (HR) and also to examine the feedback effect under such a condition. 40 normal undergraduates were randomly assigned to one of 4 groups : 1) Respiration-Feedback (R-F) group 2) Respiration-No Feedback (R-NF) group 3) No Respiration-Feedback (NR-F) group 4) No Respiration-No Feedback (NR-NF) group While R-F and R-NF groups were allowed to use the respiration to control the HR, NR-F and NR-NF groups were instructed not to change the respiration. After 5-minute adaptation period, each subject was given two training sessions for increasing and decreasing the HR and one final test session. During training sessions, feedback groups were provided with the HR feedback (meter flactuation and digital presentation). In the test session, all groups tried to control the HR without any feedback. All groups showed increasing and decreasing the HR in training and test sessions, and there was a main group effect in test session. For increasing the HR, the changes were greater in respiration groups than no respiration groups. However, there were only small changes (within 4 bpm) in all groups for decreasing the HR. The present results indicated that : 1) The Respiration facilitated the HR increase. 2) But it didn't give such an efiect on the HR decrease. 3) The HR increase was correlated with the increase of respiration rate. 4) There was no significant difference between feedback groups and no feedback groups. 5) It was suggested that the respiration amplitude effected the HR change. 6) Individual differences in respiration groups must be examined more precisely.
