Note: Data were shown as mean ± standard deviation.

¹p: Results of the comparison between Pre and Post test.

²p: Results of the comparison among five approaches (percentages of body weight).

According to pairwise comparisons of repeated measures ANOVA

^aThere was statistically significant difference from %2

^bThere was statistically significant difference from %4

^dThere was statistically significant difference from %8
