Appropriate cardiovascular adjustment is necessary to meet the metabolic demands of working skeletal muscle during exercise. The sympathetic nervous system plays a crucial role in the regulation of arterial blood pressure and blood flow during exercise, and several important neural mechanisms are responsible for changes in sympathetic vasomotor outflow. Changes in sympathetic vasomotor outflow (i.e., muscle sympathetic nerve activity: MSNA) in inactive muscles during exercise differ depending on the exercise mode (static or dynamic), intensity, duration, and various environmental conditions (e.g., hot and cold environments or hypoxic). In 1991, Seals and Victor [6] reviewed MSNA responses to static and dynamic exercise with small muscle mass. This review provides an updated comprehensive overview on the MSNA response to exercise including large-muscle, dynamic leg exercise, e.g., two-legged cycling, and its regulatory mechanisms in healthy humans.

运动时肌肉交感神经活动。


适当的心血管调节对于满足运动期间工作骨骼肌的代谢需求是必要的。交感神经系统在运动过程中动脉血压和血流的调节中起着至关重要的作用，并且几种重要的神经机制负责交感血管舒缩流出的变化。运动过程中不活跃肌肉的交感血管舒缩流出量（即肌肉交感神经活动：MSNA）的变化因运动模式（静态或动态）、强度、持续时间和各种环境条件（例如冷热环境或缺氧）而异。 。 1991 年，Seals 和 Victor [6] 回顾了 MSNA 对小肌肉量静态和动态运动的反应。这篇综述提供了 MSNA 对运动的反应的最新全面概述，包括大肌肉、动态腿部运动，例如两腿骑自行车，及其在健康人类中的调节机制。
