本研究旨在探讨耐力运动训练是否会改变外周血管对跨壁压改变的反应。健康男性受试者（训练组; n = 6）进行耐力运动训练，包括自行车测力计运动5 d.周-1和30 min.d-1，持续8周。外周血管对人手指跨壁压改变的反应的变化通过差分数字光电容积描记图（DeltaDPG）和手臂被动运动到相对于心脏水平的不同垂直手位置期间的血压来测量。经过8周的耐力训练后，训练组中DeltaDPG相对于心脏水平的百分比变化显著增加（平均值+/- SD，-48.1 +/- 7。3至-58.7 +/- 9.3%，在降低位置，46.1 +/- 13.4至84.6 +/- 8.8%，在升高位置，p<0.05）。同样，训练组的动脉顺应性指数（根据DeltaDPG-P波振幅和动脉脉压计算）在8周内也发生了显著变化（5.6 +/- 1.3至2.7 +/- 1.6 mV。V-1.s-1.mmHg-1，在降低位置，30.0 +/- 12.4至54.4 +/- 18。9mV.V-1.s-1.mmHg-1）。训练组的最大摄氧量（V.O2max）显著增加。另一方面，对照组（n = 6）在8周内所有参数均无显著变化。因此，这些结果表明，耐力运动训练诱导外周血管反应的增加，以改变跨壁压在人的手指。
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 (DeltaDPG) 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 DeltaDPG 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 DeltaDPG-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 54.4 +/- 18. 9 mV.V-1.s-1.mmHg-1 at the elevated position ). Maximal oxygen uptake (V.O2 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.
