P for multivariate analysis used the GLM program with sex as a fixed factor

Comparison of means within sex subgroup using t-test:

^aP < 0.05;

^bP < 0.001

SEM, standard error of the mean; NS, not significant; TBN, total body nitrogen; NI, nitrogen index, %BFat, percentage body fat; FM, fat mass; TBW, total body water; BMI, body mass index; TBK, total body potassium; TBK/Ht, total body potassium/height; LBM, lean body mass
