Why is Athlete Mode necessary in a Body Fat Scale?

It was found that body fat estimation using bioelectrical impedance analysis (BIA) can overestimate the body fat percentage of adult athletes. The physiological variations of athletes are said to account for the difference in body composition compared to the average person with a moderately active lifestyle. Such variations include higher bone density and hydration levels in athletes. Therefore, to get the most accurate measurement results, adult athletes should turn on Athlete Mode in the Renpho app.
