The purpose of this study is to investigate the effects of recumbent bicycle ergometer exercise on cerebral blood flow velocity (CBFV), ankle brachial index (ABI) and rate pressure product (RPP). In a randomized, balanced crossover study, seventeen young male volunteers (20.2±1.5yrs) were asked to perform the incremental bicycle ergometer exercise three times in the upright, 65° recumbent (R), and 30° postures with a week interval, respectively. Exercise intensity was set initially at 50W and increased by 25W every 2 minutes to 150W. CBFV in middle cerebral artery (MCA) and arterial stiffness were measured at rest, 5 minutes, 10 minutes during exercise and 10 minutes recovery using transcranial-Doppler sonography and arterial stiffness devices. All data were analyzed using two-way ANOVA with repeated measures. The results of this study are as follows. 1) CBFV in 65°R and 30°R was significantly higher than in upright posture at 5 minutes (75±14, 76±8 vs. 63±12cm/s, p<.05) and 10 minutes during exercise (87±20, 88±18 vs. 69±19 cms/, p<.05). 2) TABI in 65°R was significant higher than in upright posture at immediately afte rexercise (1.03±0.08 vs. 0.94±0.11 ml, p<.05). 3) RPP in 47°R and 15°R was significantly lower than in upright posture at immediately after exercise (10988.0±1406, 10765±2362 vs. 11960.7±1592 mmHg×beat/min, p<.05). These results suggest that the bicycle ergometer exercise in recumbent posture has some hemodynamic benefits and safety, and therefore can be recommended for heart disease patients.
