Comportamento agudo de variáveis hemodinâmicas de hipertensos sedentários, em diferentes intensidades de treinamento resistido

Abstract

The objective of this study was to analyze and compare the acute hemodynamic behavior of hypertensive sedentary, subjected to different intensities of resistance training. Study participants were hypertensive (GH, n = 10) of both sexes, mean age 54.8 ± 7.2 years, height 160.6 ± 7.4 cm, body mass of 78.7 ± 14 Kg and BMI of 30.5 ± 5.5 Kg/m², and normotensive (GN, n = 5) of both sexes, mean age 54 ± 3.5 years, height 175.6 ± 4 cm, mass body of 84.8 ± 13.8 Kg and BMI 27.5 ± 4.3 Kg/m². Both were submitted to two protocols of resistance training, 50% and 70% intensity in the bench press exercise machine, leg press 45, pulled triceps and knee extensor. For statistical analysis we used the Wilcoxon test with a significance level of p <0.05. Significant differences for the variables HR, SBP and DP when both groups were submitted to training intensity of 50% and for HR and DP when the intensity was 70%. The results suggest that there was less when applied hemodynamic overload protocol higher intensity and a lower volume. Furthermore, no significant difference when comparisons were between groups in both resistance training protocols, resulting in similar responses on hemodynamic variables for GH and GN, the same age and fitness level.
