Introduction
he corporal composition is considered as a component of the physical aptitude related to health, due to relations existent between the quantity and the distributions of body fat with alteration in a physical aptitude level as well as in the people health state [1]. The aim of this work is to study how those anthropometric indicators relate to the metabolic variables: blood pressure and heart rate in pre-effort and effort situation.

Methods
This work was carried out with 69 individuals of both sex (33 male and 36 female) ages between 28 to 57 years old. The test was realized in a treadmill and the modified Bruce protocol was applied. It was analyzed the metabolic variables: blood pressure and heart rate before and after the test. It was also analyzed the anthropometrical evaluation in order to analyze the Body Mass Index (BMI), the body fat percentage (% BF), and the index of waist-rip ratio (W/R) of the individuals. In order to analyze the association between the anthropometrical and metabolic variables, an statistical analysis was carried out using the "Statistical" software, version 5.0, used to analyze the correlation index through the determination of the Pearson correlation coefficient "r", with test of statistical significance (p < 0.05)

Results
The female group presented the highest index of correlation between blood pressure and the BMI, not showing the same results with the correlated between this metabolic variable and the (W/R), due to fact that the distribution of female fat (ginoide) do not relate with the values of blood pressure of these group. The levels of the blood pressure of the male group were more dependent on the high concentration of fat in the central region of the body, as compared to the female group [2].

Discussion / Conclusion
Information related to BMI were those given more association with the systolic and systolic blood pressure, with similar statistically values for both sex, with a substantial impact of overweigh in the blood pressure levels [2]. The Maximum Time Test on treadmill, presented correlation only to the fat percentile but in a negative form, i.e., the higher the fat percentile the smaller the duration of the test. These data is in accord with similar data reported by McArdle et. al. [3], who states that that epidemiological evidences suggest an inverse association between physical activity and the corporal weight .
