![]() In other words, both groups showed improvement in lower limb flexibility during the same time interval. From comparison of the mean age between the groups, it was concluded that there were no significant differences regarding the mean age of the subjects in each group (p = 0.169), thus showing age homogeneity in the whole sample. ![]() RESULTS AND DISCUSSION The mean age of the sample analyzed was 21.23 ± 2.07 years, with the minimum being 18 years and the maximum being 27 years. All the tests utilized in this research used a value of 0.05 for statistical significance and a confidence interval of 95%. ![]() Inferential statistics were utilized to compare the means of the groups by means of ANOVA for repeated measures, which compared lumbar flexibility before and after application of KT, as well as the means of the control, KFC, and KST groups. Analysis of variance (ANOVA) was used to assess the independent sample and found the mean age between the groups. Only the value of BMI showed an abnormal distribution (p = 0.01), and to check the difference between the average positions of BMI groups, the Kruskal-Wallis test was used the Mann-Whitney test with Bonferroni correction significance was applied for the differences between pairs. To verify the normality of the distribution of scalar variables, the Shapiro-Wilk test was utilized, and for all the variables that had a normal distribution, a parametric test was applied.
