Summary:
Patients with chronic heart failure face reductions in their quality of life, in strength and in other parameters of cardiopulmonary exercise testing. Aim of this study was to examine which of two rehabilitation programs is best for them. In this study 27 CHF patients participated. They were separated in two rehabilitation programs. The protocol was starting with a “warm-up” phase for 3 minutes at 50% of their VO2peak. Both programs trained for 28 minutes. The aerobic part of programs was consisted of interval training circles. Each circle was consisted of 4 minutes at 85% of VO2peak 3 minutes at 50% VO2peak. The first rehabilitation program (AER) had 4 circles. The second (COMB) had 2 circles and 2 extra exercises for strength training. One exercise for quadriceps and one exercise for biceps femoris for 3 sets of 8-10 repetitions at 60-75% of one maximum repetition. Parameters for evaluation before and after the rehabilitation programs were strength, quality of life, VO2peak, Watt, anaerobic threshold, VE, breathing reserve and VE/VCO2 slope. Strength showed a significant difference in the combined program. Quality of life was significant changed among all patients. No difference was found among the programs. Separating quality of life in two groups similar results were found. In first category, that was about physical activity, significance was found among all patients, but no change was found when groups were compared. In second category, about emotional situation, changes were found in both groups and in combined group separately. No significance was found in aerobic group. As for the parameters of cardiopulmonary exercise testing no significant changes were found between groups in VO2peak, watt, VE, AT, BR and VE/VCO2 slope. Changes were found in VO2peak, watt, VE, and AT in both groups, when compared separately. BR was found significant changed only in combined group. Summarizing, benefits from both groups were similar, but in the combined group we found a significant change in strength too, giving a small evidence about which program is better.
