TREINOS “FOR TIME” E “AMRAP” DE CROSSFIT INDUZEM A HIPOTENSÃO PÓS-EXERCíCIO

RESUMO Objetivo: Avaliar as respostas hemodinâmicas de adultos saudaveis durante e apos duas sessoes de treinamento de CrossFit®, utilizando diferentes metodos. Metodos: 14 individuos do sexo masculino, normotensos, fisicamente ativos, com idade entre 25 e 35 anos, residentes no Distrito Federal, formaram a amostra. Os protocolos For Time e AMRAP foram aplicados. Foi mensurada a pressao arterial sistolica (PAS) e diastolica (PAD) e frequencia cardiaca (FC) 15 minutos antes do inicio dos treinos. Entre cada bloco, houve intervalo de 3 minutos para mensuracao da PAS, PAD e FC, que tambem foram mensuradas apos 15, 30, 60 e 120 minutos. Resultados: Na analise da PAS, houve diferenca significativa quando os treinos For Time e AMRAP foram comparados com o controle nos momentos de stress pre, com 15 e 30 minutos apos as intervencoes. Com 45 e 60 minutos apos as intervencoes, houve diferenca significativa apenas do treino For Time em relacao ao controle. Conclusao: O treinamento de CrossFit, realizado com os metodos “ For Time ” e “ AMRAP ”, foi eficiente na atenuacao da PAS e PAD em homens normotensos verificados durante o transcorrer de 2 horas apos a realizacao dos treinamentos.

ABSTRACT Objective: To evaluate the hemodynamic responses of healthy adults during and after two CrossFit® training sessions using different methods. Methods: 14 physically active normotensive male individuals, aged 25 to 35 years, residing in the Federal District, formed the sample. The For Time and AMRAP protocols were applied. Systolic (SBP) and diastolic (DBP) blood pressure and heart rate (HR) were measured 15 minutes before the beginning of training. Between each block there was an interval of 3 minutes to measure SBP, DBP and HR, which were also measured after 15, 30, 60 and 120 minutes. Results: In the SBP analysis, there was a significant difference when the For Time and AMRAP training were compared with the control moment in the pre stress, 15 and 30 minutes after the interventions. At 45 and 60 minutes after the interventions, there was a significant difference only for For Time training in relation to the control moment. Conclusion: CrossFit training, performed with the “ For Time ” and “ AMRAP ” methods, was efficient in attenuating SBP and DBP in normotensive men verified during 2 hours after the training. Key words: arterial hypertension, exercise, CrossFit®, hypotension pos-exercise. Figshare DOI:  10.6084/m9.figshare.11196389
