A Cycle Ergometer Exercise Program Improves Exercise Capacity and Inspiratory Muscle Function in Hospitalized Patients Awaiting Heart Transplantation: a Pilot

Abstract

ObjectiveThe 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.MethodsPatients 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.ResultsBoth 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).ConclusionStationary 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.

Effects of inspiratory muscle training on walking capacity of individuals after stroke: A double-blind randomized trial

“…Studies with cardiac patients with respiratory muscle weakness have shown that aerobic exercise increases maximal respiratory pressures. 20 Probably the mechanism responsible for the increase in respiratory muscle strength related to aerobic exercise is the improvement of respiratory muscle perfusion, with improvement in oxidative capacity, similar to what occurs in peripheral muscles. 21 Improvement in maximal respiratory pressures is also described as increased in weightlifters when compared with sedentary individuals, and in bodybuilders when compared to endurance athletes.…”

“…10 Increased RMS may contribute to improved dyspnea and exercise tolerance, in order to delay diaphragmatic fatigue. 23 In this context, other studies have demonstrated that there is a direct relationship between the increase in RMS and peripheral muscle strength. 23,24 Thus, the present results suggest that the RMS improvement may also have contributed to improved peripheral muscle strength.…”

A intervenção do fisioterapeuta no pré e pós-operatório de cirurgia cardíaca: uma revisão integrativa

“…Deste modo corroborando com os estudos de um estudo randomizado e controlado (Forestieri et al, 2016), em dois grupos: 1) Grupo de controlo (n = 11) -protocolo convencional; e 2) Intervenção grupo (n = 7), estacionário cicloergômetro exercício de formação (Cavenaghi et al, 2011;Forestieri et al, 2016).…”

“…Entre tanto, a fisioterapia é de suma importância, visto que previne complicações respiratórias e motoras devolvendo ao paciente sua capacidade funcional integra. Desta forma, mais estudos clínicos são necessários para uma melhor compreensão voltados para intervenção, criando protocolo terapêuticos para auxiliar na conduta terapêuticas como prática baseadas em evidência na população estudada (Cerqueira, 2018;Forestieri et al, 2016;Winkelmann et al, 2015).…”
