The purpose of this study is to investigate the hemodynamic responses based on exercise intensities in patients with cardiovascular disease when exercise was conducted on treadmill and cycle erogometer by turns. The subjects of this study underwent internal procedure due to acute coronary syndrome. As for methodology, exercise intensities of HRR 60% and HRR 85% were obtained through treadmill exercise stress test. The hemodynamic responses were observed during treadmill exercise (A), treadmill and bike exercise (B), bike exercise (C), and treadmill and bike exercise (D). The results of this study showed that, when treadmill and bike exercises were separately conducted at HRR 60% and HRR 85%, systolic blood pressure, diastolic blood pressure, and RPP were significantly increased during bike exercise (p<.001). As for RPP based on the exercise order at HRR 60%, C was significantly higher than A and B (p<.05). As for RPE, C was significantly higher than A and B (p<.05) and D was significantly higher than B (p<.001). As for RPP based on the exercise order at HRR 85%, C was significantly higher than A and B (p<.05) and D was significantly higher than B (p<.05). AS for RPE, C and D were significantly higher than A and B (p<.001). In conclusion, higher RPP and RPE were observed during bike exercise same exercise intensity regardless of the order of exercise. Thus, when exercise intensity is applied to bike exercise, caution may be needed when reaching HRR 85% and it may be appropriate to observed RPE of “somewhat hard.”
