PEREIRA-RODRIGUEZ, Javier Eliecer et al. Functional capacity, strength and quality of life after a heart failure training program. Randomized clinical trial. Rev. virtual Soc. Parag. Med. Int. [online]. 2021, vol.8, n.1, pp.11-24. ISSN 2312-3893.


Heart failure is considered the millennium pathology, whose mortality is increasing and its effects are reflected in the quality of life.


To identify changes in functional capacity, strength and quality of life after a training program in patients with heart failure.

Methods and materials:

Randomized controlled trial over a period of 3 years with a sample of 920 patients with heart failure distributed in 3 groups (only aerobic exercise, aerobic exercise plus training for MMSS, aerobic exercise plus MMII training). Aerobic capacity, maximum heart, anthropometry, depression and anxiety (HADS Test), clinical and hemodynamic parameters measurements and the Minnesota Living with Heart Failure Questionnaire and the New York Heart Association were performed. The tests were performed before and after 24 60-minute training sessions, 3 times a week for two months.


In the prehensile force the GE1 had a great improvement compared to the GE2 (31±6.4 vs 28±5.0; p= 0.001) and GC (31±6.4 vs 24±9.2; p=0.001) and the quality of life improved significantly in the experimental groups compared to the control group (GC:49.1±8.8 vs. GE1:40.5±4.5; p=0.000) (GC:49.1±8.8 vs. GE2:34.5±6.9; p=0.000) (G1:40.5±4.5 vs. GE2:34.5±6.9; p=0.000). In addition, variables such as functional capacity, depression, anxiety, anthropometry and ejection fraction were improved.


In patients with heart failure, the use of muscular strength exercises is recommended, which increase functional capacity, quality of life and improve associated variables such as depression and anxiety.

Trial registration: NCT03913780.

Keywords : physicalexercise; heart failure; cardiac rehabilitation; muscular strength.
