Abstract Aim: To investigate the hypothesis that the resistance exercise (RE) may be safer if the blood pressure (BP) is properly controlled through antihypertensive pharmacological treatment in hypertensive middle-aged women. Methods: The final sample was comprised of 19 hypertensive women, with an average age of 58±5 years and a body mass index of 29±5 Kg/m2. They were divided into three groups: controlled (n=6), uncompensated (n=8), and untreated (n=5). The subjects from all groups were submitted to a test of maximal strength on extensor chair and held a session of RE (knee extension, 3x12 to 60% 1RM) and the cardiovascular response (BP and heart rate) was monitored continuously by photoplethysmography during exercise and until five minutes after exercise (recovery). Results: Systolic BP (SBP) and diastolic BP (DBP) responses were lower in the controlled group compared to the other groups (p<0.05). The heart rate was not different between groups, while the double product was lower in the controlled group compared to the untreated group (p<0.05). The SBP and DBP peaks were lower in the controlled group compared to the other groups (p<0.05). Conclusion: The BP increases significantly during RE when the hypertension is not controlled. Pharmacological control was shown to be effective in preventing the increase of BP during the performance of the RE.

O objetivo deste trabalho foi comparar a biometria de frutos e sementes, a embebição e germinação de duas populações de Erythrina velutina coletadas na região semiárida do Estado de Pernambuco, nas áreas de caatinga (Alagoinha) e no brejo de altitude (Poção). Os frutos e as sementes foram avaliados quanto ao comprimento, largura, espessura (cm) e peso (g). Com relação às sementes, foram analisados o número por fruto, o volume (cm³) e a embebição, bem como a germinação com e sem escarificação mecânica, na presença constante de luz a 25 ºC. Os frutos e sementes do brejo apresentaram os valores assim discriminados: 9,65 x 1,57 x 1,22 cm, 1,43 g e 1,34 x 0,92 x 0,78 cm, 0,46 g; e na caatinga: 6,85 x 1,19 x 1,03 cm, 0,21 g e 1,06 x 0,63 x 0,63 cm e 0,26 g. O número de sementes e o volume no brejo e caatinga foram de 2,33 e 1,38 cm³ e 1,40 e 0,23 cm³, respectivamente. Todas as sementes escarificadas apresentaram maiores valores de embebição e porcentagem de germinação. Quanto à velocidade de germinação, foi maior na caatinga. Esses resultados indicam que as condições ambientais do brejo de altitude favorecem o desenvolvimento dos frutos e das sementes.

The objective of this study was to compare the biometry of fruits and seeds, the imbibition and germination of two populations of Erythrina velutina collected in semi-arid region of Pernambuco state, in areas of caatinga (Alagoinha) and brejo de altitude (upper land swams) (Poção). The fruits and seeds were evaluated for length, width, thickness (cm) and weight (g). Regarding the seeds, it was analyzed the number per fruit, volume (cm³), embebition and germination with and without mechanical scarification at the presence of constant light at 25° C. The fruits and seeds from the swamp presented the following values: 9.65 x 1.57 x 1.22 cm, 1.43 g and 1.34 x 0.92 x 0.78 cm, 0.46 g; and the ones from presented the following values: 6.85 x 1.19 x 1.03 cm; 0.21 g and 1.06 x 0.63 x 0.63 cm and 0.26 g. Number of seeds per fruit and volume in the swamp and Caatinga were 2.33 and 1.38 cm³ and 1.40 and 0.23 cm³, respectively. All scarified seed from both places presented the highest values for embebition and percentage of germination. Germination rate was the highest in seeds from Caatinga. These results indicate that the environmental conditions of the upper land swamp favored the development of the fruits and seeds.
