Abstract in Portuguese
Recomenda-se o exercício resistido para hipertensos, entretanto, sua segurança não esta estabelecida. Investigamos o efeito do exercício resistido na pressão arterial (PA) de hipertensos estágio I.Cinco hipertensos (HT) e 6 normotensos (NT) realizaram exercício de extensão de joelhos até a exaustão em 3 intensidades: 1 série em 100% e 3 séries em 80% e 40% de 1 repetição máxima (1RM) com medida intra-arterial da PA. Nos 2 grupos PAS e PAD aumentaram na 1ª série nas 3 intensidades. Nos HT, o aumento da PAS em 40 e 80% 1RM foi maior que em 100% 1RM, mas o da PAD foi semelhante. Durante as 3 séries de exercício em 80 e 40% da 1RM, PAS e PAD aumentaram de forma semelhante nos NT. Nos HT, PAS aumentou mais em 40 que em 80% da 1RM, mas PAD foi semelhante.O exercício resistido de extensão de joelhos até a exaustão promove elevação da PA em HT e, contrariamente ao esperado, esse aumento é maior no exercício de menor intensidade. Esses resultados sugerem que a indicação desse exercício nessa população deve ser feita com cautela

Blood pressure in mild hypertensives during different intensities of resistive exercise

Abstract in English
Resistive exercise has been recommended to hypertensives. However, little is known about its safety. This study had investigated the effects on blood pressure of resistive exercise.Five mild hypertensives (HT) and 6 normotensives (NT) performed knee extension exercise to exhaustion in 3 intensities: 100% one maximum repetition (1RM) and 3 series at 80% and 40% 1RM. Blood pressure was obtained by intrarterial measurement.SBP and DBP increased in 100% 1RM and in the 3 series of the 80% and 40% of 1RM in both groups. In HT, SBP increase in 80% and 40% was greater than in 100% 1RM but the DBP rise was similar. During the 3 series of 80% and 40%, SBP and DBP increased similarly in NT. In HT the SBP increase was higher in 40% than in 80% 1RM, but DBP elevation was similar in the 2 intensities.Knee extension resistive exercise performed to exhaustion provokes expressive blood pressure elevation in HT and, unexpectedly, this increase is greater in the low intensity exercise. These results suggest that this exercise should be recommended with caution in hypertensives
