When you set up a user profile on most Tanita Body Composition Monitors and Tanita Body Fat & Hydration Monitors, you may notice that it asks you if you are an athlete. There is a very important reason for this, and it is important to select the correct setting based of your lifestyle.
Why is there a separate Athlete mode feature on Tanita Body Composition Monitors?
Athletic body types are physiologically different than standard adult body types, due to muscle mass and hydration level differences. Athletes tend to have greater muscle mass and tend to be more dehydrated. These differences would skew the body fat reading high, when taken with the standard Adult mode.
