ABSTRACT

Introduction: the use of muscular resistance training on patients with chronic heart failure and reduced ejection fraction of the left ventricle (IC-FED) has been controversial. Therefore, it was decided to evaluate the effect of a physical aerobic training of muscular strength resistance oh these patients.
Method: A longitudinal, prospective experimental was made with 56 patients devided into groups of 28: one control and the other a study group. A six-month tracing was applied with the assessment of variables referred to morphofunctional, life quality related to health with or without the presence of complication during the investigation.
Results: According to the varianza analysis (ANOVA) there was a statistical mean increase (p<0,001) of peak oxygen consumption (VO2 peak) in both groups:14,3-18,5-19,3 ml/kg/min in the control group and 19,3-18,6-21,2 ml/kg/min in the study group. The ejection fraction of the left ventricle got better statistically meaningfull the both groups, although not in every evaluating stage as indicated by the HSD Tukey test. In the study group there was a statistically meaningfull increase of the magnitude of the working weight in the muscular groups evaluated: Biceps 4,8-6,7-9,6kg; Triceps 4,0-6-1-9,0 kg and Cuadriceps 11,2-14,7-18,6kg. The safety variables for this training range normal. There was statiscally meaningfull bettering of the life quality realted to health in both groups.
Conclusions: The combination of physical aerobic training with resistance of muscular strength improves the morphofunctional parameters, of life quality related to health without riks of generating complications.
