About

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).

Full description

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.

Enrollment: 30 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• chronic heart failure (functional class from NYHA II and III),

---

30 participants in 3 patient groups

Control group

Other group

Description:

patients awaiting for evaluation to cardiac rehabilitation or transplantation

Treatment:

Other: control

moderate-intensity group

Experimental group

Description:

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).

Treatment:

Other: moderate-intensity group

low-intensity group

Active Comparator group

Description:

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).

Treatment:

Other: low-intensity group
