Comparison of near-infrared light spectroscopy, bioelectrical impedance and tritiated water techniques for the measurement of fat-free mass in humans.

Fat-free mass (FFM) was measured with three different methods: near-infrared spectroscopy, bioelectrical impedance and tritiated water technique, in 76 (39 females/37 males) subjects (age 47 +/- 2 [SEM] years, BMI 26.8 +/- 0.6 kg m-2). From bioelectrical impedance measurements FFM was calculated with manufacturers formula and a formula developed by… CONTINUE READING
