the best prediction formulas for the ffm from body impedance and anthropometric variables were 1 ) ffm ( kg ) = ( 0.671 x 10 ( 4 ) x h2/r ) + 3.1s + 3.9 where h is body height ( m ) , r is resistance ( omega ) , and s is gender ( females , 0 ; males , 1 ) ( r = 0.94 ; see = 3.1 kg ) and 2 ) ffm ( kg ) = ( 0.360 x 10 ( 4 ) x h2/r ) + 0.359bw + 4.5s - 20t + 7.0 where bw is body weight ( kg ) and t is thigh circumference ( m ) ( r = 0.96 ; see = 2.5 kg ) .
