O objetivo deste estudo foi avaliar os efeitos cardiovasculares agudos do exerc赤cio resistido (ER) em idosas com hipertens o est芍gio I. Participaram 24 hipertensas (63,7 ㊣ 3,7 anos), submetidas a uma sess o de ER, constitu赤da por oito esta es (tr那s s谷ries,12 repeti es, 50% 1 RM). A frequ那ncia card赤aca (FC), a press o arterial sist車lica (PAS) e a diast車lica (PAD) foram mensuradas anteriormente ao in赤cio dos exerc赤cios (A), imediatamente ap車s a quinta esta o (B) e 10 min. ap車s a sess o de exerc赤cios (C). Anova demedidas repetidas e post-hoc Tukey (p %26lt; 0,05) foram utilizados. Os resultados demonstraram aumento significativo na PAS, PAD e FC (p %26lt; 0,05) entre as condi es A e B. Subsequentemente, na condi o C, em PAS e PAD houve decr谷scimo significante em rela o 角 condi o B (p %26lt; 0,05), por谷m somente PAD reduziu significativamente para acondi o A (p %26lt; 0,05). Apesar das modifica es cardiovasculares agudas associadas ao ER, propens o positiva a hipotens o somente 谷 verificada em rela o 角 PAD. The aim of this study was to evaluate the effect of acute cardiovascular responses of resistance exercise (RE) on stage I hypertensive elderly women. Twenty four hypertensive women (63.7 ㊣ 3.7 years) were subjected a session of RE, with eight stations(3 sets, 12 repetitions, 50% 1 RM). The heart rate (HR), systolic blood pressure (SBP) and blood pressure (DBP) were measured before the exercise sessions (A), immediately after the fifth station (B), and 10 minutes after the exercise sessions (C). Repeated measuresAnova and post-hoc Tukey test (p %26lt; 0.05) were performed. The results demonstrated significant increase in SBP, DBP and HR (p %26lt; 0.05) between the A and B conditions. Subsequently, SBP and DBP decreased significantly for the C condition as compared to the B condition (p %26lt; 0.05); however, only DBP decreased significantly for the A condition (p %26lt; 0.05). Although the results demonstrated that acute cardiovascular modifications are associated with RE, hypotensive effects were only verified on DBP.
