Efeito do treinamento em cicloergômetro no consumo máximo de oxigênio e força muscular em idosos portadores de ICC: uma revisão da literatura

Abstract

Introduction: Chronic Heart Failure (CHF) is a complex clinical syndrome that can lead to dyspnea, fatigue, and exercise intolerance. This condition is prevalent in the elderly population, which is continuously growing in Brazil. The cardiovascular rehabilitation in CHF includes aerobic exercises, with particular emphasis on cycle ergometer training, aiming to improve functional capacity and control metabolic factors. Objective: To assess the effects of cycle ergometer training on maximal oxygen consumption (VO₂max) and muscle strength in elderly individuals with CHF. Methodology: A narrative literature review was conducted using scientific databases and the CAPES Portal, applying the following inclusion criteria: studies involving elderly individuals with CHF and the use of lower limb cycle ergometer as the main intervention. Exclusion criteria included: studies with a mean age below the elderly threshold (60 years) and those using the cycle ergometer as a secondary intervention. Results: The search strategy yielded 67 articles. After the selection process, 8 studies were included, most of which were randomized clinical trials. Conclusion: Significant improvements were observed in the analyzed parameters, such as VO₂max and muscle strength, with the use of the cycle ergometer in the elderly population with CHF, with good ease of use and dissemination of applied methods.
