  • Between-group comparisons evaluated using independent samples t-test and ANCOVA.

  • BMD and BMC values adjusted for age and FFM.

  • BMD Z-score values adjusted for FFM.

  • *Total body BMD and BMC values represent total body less head.

  • BMC, bone mineral content; BMD, bone mineral density; FFM, fat-free mass.
