“…In general, supervised CR programs are successful in increasing physical fitness, cardiovascular performance, quality of life and reducing mortality [5][6][7][8][9][10][11][12][13][19][20][21][22][23][24].However, there are indicat ions that only 11% to 30% of those who need CR have access to specialized centers [6,22,23,25].Taking these facts into consideration, there has been an increase in the number of programs, whether supervised or not. The effectiveness of these programs has been well documented, revealing broad benefits [19,23,[26][27][28],although other studies have failed to observe positive effects, especially those regarding quality of life [29].In the present study, patients with HF in both groups demonstrated improvement in cardio respiratory fitness and in functional capacity during the 60 intervention days, as verified by other authors [19][20][21]23,[26][27][28].Nevertheless, only the supervised CR group showed quality of life imp rovement along the 60 CR days.…”
