Abstract:
The hypothesis tested in chronic heart failure patients with inspiratory muscle weakness demonstrates that the Resistance Training results in further improvements compared to control in terms of dyspnea, cardiac, skeletal and inspiratory muscle function and quality of life. Twenty patients with ejection fraction ≤45% and inspiratory muscle weakness described by maximal inspiratory pressure <70% predicted, had undergone 3 exercise training sessions per week for 12 weeks. Patients were randomly allocated to one of two groups: RT group or control group. RT performed at 60% of 1 repetition maximum. Control group patients had no training at all. At the beginning and the end of the study, patients underwent pulmonary function test, respiratory muscle function test, echocardiography, exercise test, skeletal muscle function test, 6 minutes’ walk test and were evaluated for their quality of life using the Minnesota living with heart failure questionnaire. RT showed significant positive effects on ejection fraction, exercise test variables, functional capacity, respiratory muscle function, skeletal muscle strength and endurance as well as dyspnea and quality of life. Resistance training was superior to control in all parameters assessed, and most importantly in exercise time (68% versus 27%, P=0.008), respiratory muscle function (Maximal inspiratory pressure, 60% versus 14%, P=0.001; Sustained maximal inspiratory pressure, 71% versus non-significant improvement in resistance training group, P=0.022) and skeletal muscle endurance. However, no significants improvements were detected in control group patients. Resistance training has been applied to improve respiratory muscle strength in chronic heart failure patients. In addition, the resistance training was safe and resulted in additional benefits in cardiac, respiratory muscle and skeletal muscle function compared to the control.
