The aim of this study was to analyze the acute responses of blood pressure (BP) to a high intensity interval training (HIIT) session on a treadmill in adolescents with excess body weight. This is a study with crossover randomized design the sample consisted of 11 male adolescents aged 15 to 18 years. The volunteers performed two experimental protocols: HIIT and control. The HIIT protocol consisted of five series at 85 to 95% of VO2peak for one minute, interspersed by three minutes of recovery at 40 to 50% of VO2peak. Before and after the exercise protocols, hemodynamic parameters were obtained using an automatic ambulatory monitoring equipment (SpaceLabs model 90207), programmed to perform measurements every 20 minutes from 12:00 to 22:00 hours. A significant difference in systolic blood pressure (SBP) was only observed between the control and HIIT protocols (131.90 ± 7.93 vs 124.18 ± 7.56 mmHg, respectively) for the first hour after exercising. Comparisons of pre- and post-session (10 hours) hemodynamic measures between conditions (HIIT vs. control) demonstrated that HIIT promoted a significant reduction in mean blood pressure compared to pre-session values. In conclusion the HIIT protocol resulted in a low magnitude hypotensive effect on post-exercise hemodynamic measures with respect to SBP.
