Efeito hipotensivo de uma sessão natação em adultos fisicamente ativos

Introduction: Non-drug interventions have been indicated as a form of prevention and treatment of cardiovascular diseases. However, investigations are needed to elucidate hemodynamic responses in swimming. Objective: To verify the effect of a swimming session on the blood pressure (BP) of physically active adults. Material and Methods: Fifteen active and swimming men (26.79 ± 4.10 years) were submitted to a continuous swimming session during 30 ', with intensity between 7 and 8 of the modified Borg scale. PA measurements occurred at rest (REP), immediately after exercise (PE), and 30 'and 60' after exercise (30'PE and 60'PE). The Shapiro-Wilk normality test and the One-Way ANOVA followed by the Tukey post-hoc test were performed. The study admitted a level of p <0.05 for statistical significance. Results: systolic BP elevation at PE moment compared to REP (121 ± 3.26 vs. 153.3 ± 9.32 mmHg), and reduction at 30'PE compared to REP (121 ± 3.26 vs. 96.6 ± 2.24 mm Hg). Regarding diastolic BP, there was reduction only in 30'PE compared to PE (81.6 ± 4.03 vs. 76.3 ± 4.29 mmHg). Conclusion: a swimming session was able to induce the post-exercise hypotensive effect in active adults.
