Groups	Number	Experimental design
WBx (x = 0, 5, 12, 19, 26)	6 × 5 groups	Additional weight-bearing groups with additional weight bearing at x% of the individual body weight, backpack for 15 min/day with no weight bearing or treadmill exercise at other times.
EBx (x = 0, 5, 12, 19, 26)	6 × 5 groups	Exercise groups combined with additional weight bearing at x% of the individual body weight, treadmill exercise with backpack for 15 min/day with no weight bearing or treadmill exercise at other times.
