Efeito hipotensivo do treinamento de força utilizando diferentes intervalos entre as séries Hypotensive effect in resistance training using different rest intervals between sets

Introduction: The rest interval between sets and exercises is usually related with pressure responses after resistance training (RT). Objective: To compare the changes in systolic blood pressure (SBP) and diastolic (DBP) with different intervals. Methods: Ten subjects were divided by the crossover design into two protocols: T1 – bench press, leg press, lat pull down, leg curl and biceps curl (three sets of ten repetitions at 90% 10RM) with one min interval, T2 – similar protocol, but was adopted three minutes intervals. Results: For SBP, a significant reduction was observed after ten minutes during T1, and between 15 and 20 minutes during T2. For DBP, there was a reduction in T1 between 5 and 40 minutes. For T2, a significant reduction was observed between 15 and 20 minutes. Conclusion: The findings indicate that rest intervals between one and three minutes promoted acute hypotensive effect after a session of RT.
