Pressão arterial, frequência cardiaca e estresse oxidativo de individuos sedentários submetidos á treinamento resistido com pesos

Abstract

The purpose of this work was to analyze the behavior of both systolic blood pressure (SBP) and diastolic blood pressure (DBP), the cardiac frequency (CF) during and after the adaptation phase of a weight-resistance training in sedentary individuals and the oxidative stress after this adaptation. The research was done with 15 sedentary adult mans (45,9 ± 3,9 years). The adaptation to the weight-resistance training was done in a period of 6 weeks with 3 weekly sessions. Both blood pressure and cardiac frequency were measured before and just after each weight-resistance training session and the oxidative stress analysis done before the beginning of the training and after the 6 weeks of adaptation to this training. All the collected set of data was submitted to an statistical analysis. To compare the variables of the pretest with the posttest the Wilcoxon test and the Pearson correlation were used. The P value was of 5%. Significative statistical differences were found in the anthropometric profile regarding the isometric power and the fat percentage. In terms of cardiovascular parameters, with exception of the DBP, the other cardiovascular parameters (CF, SBP and DBP) presented significative reduction. With the regard of biochemical parameters, all those presented significative statistical results (TBARS, Tiois, Catalase), with exception of glucose. The results suggested that 6 weeks of weight-resistance training in the adaptation phase caused an important reduction in the CF, SBP and DBP and also promoted significative changes in the oxidative stress in sedentary adult mans.
