Values are unadjusted mean ± standard deviation or percentage (n). Matching superscript letters represent significant differences (p < 0.05) between age-adjusted baseline and follow-up values for each activity group, based on Tukey post-hoc analyses. BMI, body mass index; FM, fat mass; CFM, central fat mass; AFM, appendicular fat mass; VAT, visceral adipose tissue; SAT, subcutaneous adipose tissue.
