A descriptive statistical analysis, One-way ANOVA with Tukeys' post-hocs and independent sample t-tests were used to compare differences in mean anthropometric and performance scores among three groups of tactical officers. In addition, a discriminate analysis with stepwise linear regressions was used to predict group membership.
