The reduction of exercise capacity with early occurrence of fatigue and dyspnea is a hallmark of heart failure syndrome. There are objective similarities between heart failure and muscular deconditioning. Deficiencies in peripheral blood flow and skeletal muscle function, morphology, metabolism, and function are present. The protective effects of physical activity have been elucidated in many recent studies: training improves ventilatory control, skeletal muscle metabolism, autonomic nervous system, central and peripheral circulation, and heart function. These provide the physiologic basis to explain the benefits in terms of survival and freedom from hospitalization demonstrated by physical training also in heart failure.
运动能力下降并伴有早期疲劳和呼吸困难是心力衰竭综合征的一个标志。心力衰竭与肌肉失健之间存在客观相似之处。存在外周血流以及骨骼肌功能、形态、代谢和机能方面的不足。近期许多研究已阐明体育活动的保护作用：训练可改善通气控制、骨骼肌代谢、自主神经系统、中枢和外周循环以及心脏功能。这些为解释体育训练在心力衰竭患者中所显示的生存获益和减少住院率提供了生理基础。
