Interaction of peripheral reflexes in cardiovascular regulation during exercise

在本研究中，1)我们建立了量化人体动态运动中肌肉代谢性反射特征的实验技术。此外，2)我们发现在肌肉代谢性反射激活过程中，动脉压力感受性反射介导的外周血管收缩作用增强。这种外周反射的相互作用可能有助于运动过程中的心血管调节。这些发现有助于阐明运动过程中的心血管调节机制，并将为考虑运动的安全性和运动训练促进健康的有效性提供重要的理论依据。

In this study, 1) we established experimental technique to quantify the characteristics of the muscle metaboreflex during dynamic exercise in humans. In addition, 2) we found that during activation of the muscle metaboreflex, the arterial baroreflex-mediated peripheral vasoconstriction is enhanced. Such interaction of the peripheral reflexes could contribute to the cardiovascular regulation during exercise. These findings advance elucidation of mechanisms of cardiovascular regulation during exercise, and will be a significant academic base in considering the safety of exerciseand the efficacy of the exercise training in promotion of health.
