Hypotensive response after swimming practices in paused or long training
Abstract
The physical exertion of swimming is an important factor in reducing blood pressure, showing an effect of hypotension after the session, an important factor for normotensive, hypertensive and even pre hypertensives, one aspect of acting as a non-pharmacological aid and even, beyond to prevent other cardiac diseases. The objective of this study is to compare the post-exercise hypotension in normotensive adolescents during interval and continuo trainning. Methods: 15 normotensive female and male underwent two experimental sessions on different days, the first session was 30 minutes of continuous swimming and the second session were 5 shots 50m intervals of 5min. BP was measured at rest pre-exercise period and and 1 in 1 hour after exercise recovery. Results: A repeated measures ANOVA showed significant reduction after 60 min of measuring post training in both sessions. No significant interaction between time of measurement and exercise in DBP was observed. For SBP, higher values at the start of the interval trainning, consequently there was a more pronounced fall in blood pressure. Conclusion: According to our sample, the swimming exercise with continuous and interval training was effective in reducing blood pressure during the first 60 minutes, after these values remained standard, however there was a decrease in heart rate during the 3 hours evaluated.
