Suitability: Why are some of the Tanita Monitors unsuitable for athletes?

People who do large amounts of aerobic exercise will have different body types to those who don't. Their hydration levels will be different, and the composition of their muscle tissue may differ too. If such individuals use the Standard Adult mode on the Tanita Body Fat Monitor, their reading may well be overestimated. The Athlete mode, included on several of the Body Fat Monitors, takes into account these differences to give a more accurate measurement of body fat % in such individuals.
