Abstract

Exercise intolerance and dyspnea are the major symptoms of patients with chronic heart failure (CHF) and are associated with a poor quality of life. In addition to impaired central hemodynamics, symptoms may be attributed to changes in peripheral skeletal muscles. This study aimed to evaluate the effects of aerobic interval training (AIT) combined with inspiratory muscle training (IMT) on cardiac and skeletal muscle function and on functional capacity and dyspnea in patients with CHF and inspiratory muscle weakness.

Left ventricle ejection fraction was improved significantly after AIT and AIT & IMT with a high percentage of amelioration (17%, P < 0.042) in the combined group compared to the control group. Therefore, we showed a significant improvement in maximal voluntary isometric force, isometric endurance time, root mean square, and frequency median in both strength and endurance manipulations in the aerobic and combined group; however, the improvement was superior in the combined group compared to the control group. Significant amelioration was proved in functional capacity and dyspnea after all types of training but was performed at 18% higher in 6 minutes' walk test and 43% lower in dyspnea for the combined group compared to the control group.

Combining AIT to IMT had optimized exercise training benefits in reversing the cardiac remodeling process and improving skeletal muscle function, functional capacity, and dyspnea in patients with CHF.

慢性心力衰竭患者进行有氧间歇训练和吸气肌联合训练后的肌电图功率谱和心功能变化

运动不耐受和呼吸困难是慢性心力衰竭（CHF）患者的主要症状，与生活质量低下有关。除了中枢血流动力学受损外，症状还可能归因于外周骨骼肌的变化。本研究旨在评估有氧间歇训练（AIT）联合吸气肌训练（IMT）对心肌和骨骼肌功能的影响，以及对慢性心力衰竭合并吸气肌无力患者的功能能力和呼吸困难的影响。因此，我们发现有氧组和联合组的最大自主等长力、等长耐力时间、均方根以及力量和耐力操作的频率中位数都有明显改善；然而，与对照组相比，联合组的改善效果更好。在所有类型的训练后，功能能力和呼吸困难都得到了显著改善，但与对照组相比，联合组在 6 分钟步行测试中提高了 18%，在呼吸困难方面降低了 43%。
