Q:"Regarding use of the Tanita TBF-410GS body composition scale
: If I switch between "standard" and "athletic" modes when taking measurements, what changes will occur in the readout?"
Answer: The standard adult and athletic modes refer to the person's degree of physical fitness. An athlete has more lean muscle mass and less fat than the average person. So when you change the modes, the standard adult who weighs the same as the athlete will show a significantly higher amount of body fat. Bioelectrical impedance increases with body fat. And that is how the Tanita scale measures body composition.
The body fat composition scales by Tanita use leg to leg bioimpedance analysis. A barefoot person stands on two footpad electrodes on the scale platform. The body fat monitor/analyzer automatically measures weight and then impedance. Computer software (a microprocessor) imbedded in the scale uses the measured impedance, the subject's gender, height, fitness level, and in some cases age, (which have been preprogrammed), and the weight to determine body fat percentage based on equation formulas. Tanita's reference method is DEXA. Through multiple regression analysis, Tanita has derived standard formulas to determine body fat percentage. Tanita's equations are generalized for standard adults, athletes, and children.
