Abstract

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.

摘要

适当的心血管调节对于满足运动时骨骼肌的代谢需求是必要的。在运动过程中,交感神经系统在调节动脉血压和血流方面起着至关重要的作用,有几个重要的神经机制负责交感血管运动传出的变化。在运动过程中,不活动肌肉的交感血管运动传出(即肌肉交感神经活动:MSNA)的变化取决于运动方式(静态或动态)、强度、持续时间以及各种环境条件(例如,热和冷环境或缺氧)。1991 年,Seals 和 Victor [6] 综述了小肌肉量的静态和动态运动对 MSNA 的反应。本综述提供了一个关于运动时 MSNA 反应的更新的综合概述,包括大肌肉、动态腿部运动,例如,双腿骑自行车,以及其在健康人中的调节机制。
