Abstract
The purpose of this study was to compare the effects of duration-increased and intensity-increased exercise training programs on peak oxygen consumption (VO2 peak), maximal workload, and quality of life (QOL) for heart failure patients. Factors, which contribute to predict the exercise training outcomes, were determined also. A total of 21 subjects were recurited from two teaching hospitals by purposive sampling and were randomly assigned to either a duration-increased group (n=10) or an intensity-increased group (n=11). Both programs were three times per week for 8 weeks. Data were collected by using questionnairs and treadmill exercise tests and were analyzed by means of Mann-Whitney test, Wilcoxon Signed Ranks test, Spearmen’s correlation, and Multiple regression. The results of the study revealed that the VO2 peak, maximal workload, and QOL improved after 8 weeks exercise training were observed in both groups. However, the improvement in maximal workload was higher in the intensity-increased group than the duration-increased group. Both gender and group variables were significant predictors in improvement of QOL and group variable was a significant predictor in improvement of maximal workload. In conclusions, above two kinds of exercise training programs are beneficial to heart failure patients.
