MEDIANO, Mauro Felippe Felix et al. Subacute behavior of the blood pressure after power training in controlled hypertensive individuals. Rev Bras Med Esporte [online]. 2005, vol.11, n.6, pp. 337-340. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922005000600006.
Several studies have shown a benefic effect of the power exercise on the reduction in the post-exercise blood pressure (BP), but there are insufficient researches involving hypertensive individuals. Thus, the present study has as main purpose to compare the BP responses on medicated hypertensive individuals after two sessions of power exercise with different training volumes. For this, it was studied 20 individuals of both genders (61 ± 12 years) with their hypertension controlled through medication, and who participated in an exercise program, but with no experience in power training. The study was performed in three non-consecutive days. First, it was determined ten maximal repetition load in each exercise of the sequence (straight supine, horizontal leg-press, stand-up-rowing, and triceps curl). In the remaining days, the same exercises were performed in one (SER1) or three (SER3) series. The BP measurement was performed through the auscultatory method in the pre-exercise period, immediately after each session, and within 60 minutes after ending the exercises. The repeated ANOVA measurements has identified in both sessions that the systolic (SBP), and diastolic blood pressure (DBP) values measured right after ending the exercises were higher (p < 0.05) than in the pre-exercise. The 60 minutes follow-up after the SER1 showed a reduction in the SBP only in the 40th minute, while it was found no reduction in the DBP. After the SER3, it was noted a fall in the SBP levels that lasted for the whole monitoring period. As to the DBP, it was found reductions in the 30th and 50th post-exercise minute. It can be concluded that a power training session can promote reductions in the levels of the SBP on medicated hypertensive individuals, and it seems to be necessary a higher training volume for that effect to occur.
