Treinamento intervalado de alta intensidade; adultas idosas; hipertensão arterialResumo
A Hipertensão arterial sistêmica é um problema de saúde pública que acomete grande parte dos adultos idosos. Como forma de tratamento não medicamentoso o exercício aeróbio moderado mostra reduções na PAS elevada, que é conhecida como Hipotensão pós-exercício. No entanto, não sabemos se o mesmo ocorre com o exercício aeróbio intervalado de alta intensidade (HIIT). Objetivo: Analisar a resposta hipotensora de uma sessão de exercício HIIT em mulheres idosas hipertensas. Trata-se de um estudo experimental transversal, com amostra de mulheres adultas idosas, com idade ≥60 anos, hipertensas. Foi aplicado questionário contendo 17 questões para identificar e descrever a amostra. Apenas uma visita ao laboratório foi requerida, onde foi aferida a PA após 10 minutos sentadas em repouso. Logo após, foi aplicado a sessão de HIIT com duração 17,5 minutos, sendo aferida novamente a PA no momento 0 (imediatamente),10, 20 e 30 minutos. A amostra foi constituída por 10 mulheres com idade média de 70,2 ± 6,4 anos. Percebe-se que após o exercício a PAS reduziu significativamente após 20 até 30 min pós-exercício (p<0,05). A PAD demonstrou comportamento distinto se elevando ligeiramente, tendendo cair após 20 min de exercício. Uma sessão de HIIT proporcionou redução da PAS em comparação com o momento repouso (pré) podendo proporcionar melhora no controle pressórico e possíveis reduções na incidência de eventos cardiovasculares.
