Intervention / Behandlung |
|---|---|
|
Sonstiges: Control group
patients awaiting for evaluation to cardiac rehabilitation or transplantation
|
No intervention during the 8-weeks period of the study because of awaiting evaluation for cardiac rehabilitation or transplantation
|
|
Experimental: 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).
|
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) + peripheral muscle trained with exercises of upper limbs and lower limbs (50% 1 RM, increased every 2-weeks).
|
|
Aktiver Komparator: 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).
