Abstract Objective: The purpose of this study was to evaluate the effect of a cycle ergometer exercise program on exercise capacity and inspiratory muscle function in hospitalized patients with heart failure awaiting heart transplantation with intravenous inotropic support. Methods: Patients awaiting heart transplantation were randomized and allocated prospectively into two groups: 1) Control Group (n= 11) - conventional protocol

and 2) Intervention Group (n= 7) - stationary cycle ergometer exercise training. Functional capacity was measured by the six-minute walk test and inspiratory muscle strength assessed by manovacuometry before and after the exercise protocols. Results: Both groups demonstrated an increase in six-minute walk test distance after the experimental procedure compared to baseline

however, only the intervention group had a significant increase (P= 0.08 and P= 0.001 for the control and intervention groups, respectively). Intergroup comparison revealed a greater increase in the intervention group compared to the control (P< 0.001). Regarding the inspiratory muscle strength evaluation, the intragroup analysis demonstrated increased strength after the protocols compared to baseline for both groups

statistical significance was only demonstrated for the intervention group, though (P= 0.22 and P< 0.01, respectively). Intergroup comparison showed a significant increase in the intervention group compared to the control (P< 0.01). Conclusion: Stationary cycle ergometer exercise training shows positive results on exercise capacity and inspiratory muscle strength in patients with heart failure awaiting cardiac transplantation while on intravenous inotropic support.
