Body Composition Measurements
Body composition was measured using the OMRON
Fat Analyzer Model HBF-3ed (Model HB-300,
Omron Healthcare, Vernon Hills, Illinois). The analyzer
required the subject to enter data for height,
weight, age, and gender. Once these data were
entered, the subject lightly gripped the device with one
hand placed on each of 2 handles and with arms in
full extension for approximately 30 seconds. The
device returned calculated body fat percentage and
body mass index. The OMRON was chosen because
of ease of use and its use of prediction equations
encompassing upper-body impedance, age, gender,
height, weight, and activity level. The OMRON has
lower predictive errors than do other such tools in the
market.27
