Effectiveness of Combined Aerobic and Strength Training in Acute and Chronic Adaptations in Patients With Heart Failure

The subjects will perform in ST part, always only 1 set in the 6 machines early mentioned. During the first and second week they will do 12 repetitions at 40% - 50% of 1 RM. In the third and fourth week progress to 10 repetitions at 60%-70% of 1 RM, and in the second and third month, 8 repetitions at 70%-80% of 1 RM. In the AT part the HIIT protocol is based on a ratio 2 min : 1 min. Consisted of 10 interval training periods (2 min of high intensity at 85% - 90% of heart rate reserve (HRreser) and 9 pauses (1 min in passive pause) between interval training periods. During the first week of training will start with a continuous training, in the second week will start with 5 intervals of HIIT, and in the second and third months they are doing the 10 stages of HIIT.
