The parameters are grouped as directly measured properties (body mass, body height, average skin fold thickness, skin fold-corrected circumferences of extremities) and calculated properties (BMI, SM, %BF) as used for the multiple regression analysis.
BMI, body mass index; C, circumference; SF, skin fold thickness.
Values are given as mean (SD).
