Variance analysis (ANOVA) was used for body fat variability. Statistically significant differences in the sample’s body fat were found to exist between June and September, and June and December (p<0.001), but not between September and December, with a body fat increase of 4.72% during the non-teaching period and 0.41% during the teaching period.
