简要总结
Heart failure is a clinical syndrome that is the common end of several cardiac diseases with symptoms such as muscle fatigue, dyspnea and reduction of quality of life. To improve respiratory and general functional capacity of these patients, there are strategies that can be used such as inspiratory muscle training and peripheral muscle training (dynamic resistance training).
详细描述
After agreement with the written informed consent, 35 subjects with severe heart failure were included in this study. They were randomized in three groups: controls, low-intensity and moderate-intensity group. All volunteers were assessed at Baseline and 8-weeks intervention. Cardiac events were registered following two years from baseline. The present study aimed to assess the effects of a combined program of inspiratory and peripheral muscle training on respiratory and general functional capacity and quality of life in patients with chronic heart failure.

研究组 & 干预措施
Control group
patients awaiting for evaluation to cardiac rehabilitation or transplantation
干预措施: control (Other)
moderate-intensity group
Patients will be submitted to a 8-weeks training program, with inspiratory muscle trained at 30% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with upper and lower exercises (50% of the 1-maximum repetition test).
干预措施: moderate-intensity group (Other)
low-intensity group
Patients will be submited to a 8 weeks training program, with inspiratory muscle trained at 15% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with exercises of upper limbs and lower limbs (0,5 Kg each).
干预措施: low-intensity group (Other)
结局指标
主要结局
Change in respiratory muscle strength (in centimeters of water)
时间窗: Before and after 8-weeks
Inspiratory and expiratory muscle strength was assessed by using a pressure transducer (MVD-300 Microhard System, GlobalMed, Porto Alegre, Brazil).
次要结局
- walking distance(Before and after 8-weeks)
