O objetivo deste estudo foi analisar o comportamento da pressão arterial (PA) em adolescentes com excesso de peso após uma sessão de high intensity interval training (HIIT) na esteira ergométrica. Trata-se de uma pesquisa com delineamento cross-over aleatorizado, a amostra foi formada por 11 adolescentes do sexo masculino, 81,81% com obesidade e idade entre 15 e 18 anos. Os voluntários realizaram dois protocolos experimentais: controle e HIT. O protocolo HIIT foi constituído de cinco séries de 85 a 95% do VO2pico por um minuto, intercalados por três minutos de recuperação de 40 a 50% do VO2pico. Antes e após os protocolos, os parâmetros hemodinâmicos foram obtidas por meio de um monitor automático (SpaceLabs 90207), programado para realizar medidas a cada 20 minutos no período das 12:00 às 22:00 horas. Foi observado diferença signifi cativa entre as médias da pressão sistólica nos protocolos controle e HIIT somente na primeira hora após o fi nal do exercício (131,90±7,93 vs 124,18±7,56 mmHg). A comparação entre os protocolos e as medidas hemodinâmicas pré-sessão e média pós-sessão (10 horas) demonstrou que o HIIT promoveu uma redução signifi cativa na pressão arterial média em comparação a pré-sessão. Em conclusão, o protocolo HIIT empregado promoveu efeito hipotensor de baixa magnitude sobre as medidas hemodinâmicas pós-exercício no que diz respeito a PAS.
