Heart failure (HF) is a multisystemic disease leading to exercise intolerance and fatigue. Supervised physical training improves functional capacity, quality of life and reduces hospital admissions in HF patients. In this way, home physical training may be a good alternative to patients who, for any reason, cannot perform supervised training. Objective: To asses the effects of a home-based training program on functional capacity, sedentary lifestyle and quality of life of patients with chronic HF compared to supervised training.
After agreement with the written informed consent, subjects with heart failure (left ventricle ejection fraction bellow or equal 40%) will be included in this study. They will be randomized in two groups: Home-based and Supervised exercise groups. The two groups will be submitted to a twelve-week combined exercise program of aerobic and peripheral muscle training. All volunteers will be assessed at baseline and after twelve weeks of intervention. Peripheric and respiratory muscle strength as well the 6MW analyses were assessed also at 4 and 8 weeks after baseline.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Home-based exercise rehabilitation | Experimental | Patients will be submitted to a 12-weeks training program, with walking at 60-70% of heart rate reserve monitored by a heart rate monitor (30 minutes/session for 5 days/week) and peripheral muscle training including upper and lower limbs (50% of the 1-maximum repetition test) |
|
| Supervised exercise rehabilitation | Active Comparator | Patients will be submitted to a 12-weeks training program, with sessions (3 days/week) supervised by a physiotherapist, including cycling at 60-70% of heart rate reserve and peripheral muscle training of upper and lower limbs (50% of the 1-maximum repetition test) |
