A: If you are an adult who has approximately 10 hours of intense physical activity and have a resting heart rate of approximately 60 beats per minute or less, you probably need to use the Athlete Mode.
Tanita uses a mathematical formula to determine body fat percentage based upon these variables: height, weight, gender, age group and resistance (impedance). The Athlete Mode uses a mathematical formula that is different than that used in the Adult Mode. The Athlete Mode was designed through population studies of individuals meeting the above criteria.
At this time, populations of professional athletes and body builders have not been studied to establish a separate mode for this unique group. Professional athletes and body builders are advised that since the models have not been designed with them specifically in mind, they may obtain a higher than normal body fat reading. Despite this fact, many of these elite athletes have used the Tanita Body Fat Monitor/Scales successfully to gauge their progress of losing body fat. The great repeatability of the product enables one to establish a baseline and use the product for “trending purposes” to assess loss or gain in body fat over time.
