In BMD, there was a significant differencebetween the two groups in BMD lumber spine(LS). In BMD-femur, there was a significant difference in the group (p<0.01) and time(p<0.05). In body composition, there was no statistically significant difference between body mass, body mass index, body fat massand muscle volume.
