TBFP = total body fat percentage; SFT = skinfold thickness; HC = hip circumference; CaC = calf circumference; ThC = thigh circumference; BSFT = biceps skinfold thickness; ThSFT = thigh skinfold thickness; SISFT = suprailiac skinfold thickness. r = correlation coefficient, R2 = determination coefficient, and SEE = standard error of estimate. Weight in kg, height in m, circumference in cm, and SFT in mm. Correlations were significant at <0.001 level.
