국문 초록

Purpose : The purpose of this study is to compare cardiopulmonary exercise parameters during recumbent cycling(RC) and upright cycling(UC) in healthy subjects. Methods : The study population consisted of 12 healthy volunteers(male=7, mean age 29.7±5.7, female=5, 25.4±2.9 years old). Each subject was randomly assigned to perform RC or UC, and started workload at 10 watt and increased by maximal pedaling(to 100 watt). After taking a rest during 1 week, they performed cycling vice versa. Results : Baseline parameters including heart rate(HR), systolic blood pressure(SBP) and rate pressure product(RPP) are comparable between RC and UC group. Submaximal SBP(138.1±10.8 vs. 151.3±15.9 mmHg, p=0.027), submaximal RPP (15244.2±1860.8 vs. 17698.8±3325.4, p=.036), and maximal RPP(25328.3±3032.9 vs. 28443.8±3139.4, p=.022) in RC group were significantly lower than those of UC group. Peak VO 2 in RC group tends to be lower than UC group(27.2±3.6 vs. 29.5±2.8 mL/kg/min, p=.087). Conclusion : With similar exercise intensity, RC showed less cardiopulmonary stress compared with UC. These results provide the feasibility of RC based cardiac rehabilitation program in patients with heart failure or in elderly.
