Resumo(s)
A rigidez arterial tem efeitos negativos no sistema cardiovascular aumentando o risco de
desenvolver doenças cardíacas, sendo considerada um preditor independente de
morbilidade e mortalidade associada à doença. Objetivo: O presente estudo teve como
objetivo analisar a resposta aguda da rigidez arterial ao exercício de força muscular
dinâmica em pessoas com doença das artérias coronárias (DAC).
participantes do programa de reabilitação cardíaca da Faculdade de Motricidade
Humana (FMH) com DAC foram avaliados em condições experimentais. O protocolo
de recolha dos dados do modelo agudo teve a seguinte ordem: (i) uma avaliação da
carótida e da componente central 15 min antes do exercício, (ii) seguindo-se a sessão de
força muscular (6 exercícios a 70% de 1 repetição máxima) e (iii) reavaliações
efetuadas inicialmente aos 5, 15 e 30 min subsequentes ao exercício. Resultados: Não
fooram observadas diferenças significativas nas variáveis de rigidez central/aórtica,
comparativamente com o baseline, para qualquer um dos pontos medidos após a sessão
de exercício de força muscular dinâmica. Conclusão: Aparentemente, o exercício agudo
de força muscular dinâmica não afeta as variáveis centrais de rigidez arterial em
indivíduos com DAC
Arterial stiffness has negative effects on the cardiovascular system, increasing the risk of developing heart disease and being considered an independent predictor of morbidity and mortality associated with the disease. Purpose: The aim of this study was to explore the effects of acute resistance training on arterial stiffness in patients with coronary artery disease (CAD). Methods: Ten participants with CAD included in the cardiac rehabilitation program of the Faculty of Human Kinetics were tested under experimental conditions. The protocol of data collection of the acute model had the following order: (i) an assessment of the carotid and central component 15 min before exercise, (ii) followed by the resistance training session (6 exercises at 70% of 1 maximal repetition) and (iii) revaluations initially were carried out again at 5, 15 and 30 min after the exercise. Results: There were no significant differences in central/aortic stiffness variables compared to the baseline for anytime point measured post- exercise. Conclusion: Apparently, acute resistance training does not affect the central variable of arterial stiffness negatively in individuals with CAD
