For the sample size calculation was used G * Power 3.1.0 software and the procedures followed the recommendations of studies prévios45. Based on a pilot study of four volunteers, it has adopted a power of 0.95, considering a significance level of 5%, a correlation coefficient of 0.5, and 0.25 effect size for both, It calculated a "n" sample of 15 individuals for each group ("n" sample = 45). This analysis was performed to reduce the chance of Type II error and to determine the minimum number of individuals required for this investigation. Thus, the sample size was sufficient to provide 95.5% statistical power.
