a
Weekly total weight lifted is the mean of the sum of the total weight lifted during each week for each participant.
b
Does not include 5-minute warm-up and 5-minute cool down.
c
Step counters were removed during exercise intervention; thus, daily steps do not include steps obtained during intervention treadmill walking.
d
During the weeks of 12 (month 3) and 24 (month 6) the aerobic dose was reduced by one-third.
