Data are presented as mean ± SD or median (IQR). F, female; WC, waist circumference; WHR, waist to hip ratio; WHtR, waist to height ratio; MRI, magnetic resonance imaging; VAT, visceral adipose tissue; CSA, cross-sectional area; DXA, dual-energy X-ray absorptiometry. Body fat (%), android fat (kg), and android fat (%) were calculated using dual-energy X-ray absorptiometry. , for pre-post intervention within group difference.
