Abstract

The purpose of this study was to clarify whether peripheral vascular response to alteration of transmural pressure is changed by endurance exercise training. The healthy male subjects (training group; n=6) performed endurance exercise training that consisted of cycle ergometer exercise 5 d·week^-1 and 30 min·d^-1 for a period of 8 weeks. Changes in the peripheral vascular response to alteration of transmural pressure in the human finger were measured by a differential digital photoplethysmogram (ΔDPG) and blood pressure during passive movement of the arm to different vertical hand positions relative to heart level. Following 8 weeks of endurance training, percent changes in ΔDPG from heart level in the training group increased significantly (mean±SD, −48.1±7.3 to −58.7±9.3% at the lowered position, 46.1±13.4 to 84.6±8.8% at the elevated position, p<0.05). Similarly, the arterial compliance index, which was calculated from ΔDPG-P wave amplitude and arterial pulse pressure, also significantly changed in the training group over the 8 weeks (5.6±1.3 to 2.7±1.6 mV·V^-1·s^-1·mmHg^-1 at the lowered position, 30.0±12.4 to 54.5±18.9 mV·V^-1·s^-1·mmHg^-1 at the elevated position). Maximal oxygen uptake (VO_{2 max}) was significantly increased in the training group. On the other hand, the control group (n=6) showed no significant changes in all parameters for 8 weeks. Therefore these results suggest that endurance exercise training induces an increase in peripheral vascular response to alteration of transmural pressure in the human finger.
