Just got a new garmin index today. Does anyone know why there is such a hugh difference in muscle mass readings between the garmin index and other Tanita scales I own?
My Tanita BC-1000plus reading of Skeletal Muscle Mass is 155 lbs the Garmin Index reading is 85.7 lbs which is a hugh difference. I went out to try to understand why it may be different and this is what their definition of Skeletal muscle mass is:
The Garmin Index Smart Scale will measure and record skeletal muscle mass. Skeletal muscles are made up of voluntary muscles that contract upon command from conscious thought. Skeletal muscle mass does not include cardiac or smooth muscle, which contract without conscious thought. Some examples of muscles that do not get measured by the scale include: the heart, arteries, veins, and intestines.
Tanita - Muscle mass includes the skeletal muscles, smooth muscles such as cardiac and digestive muscles and the water contained in these muscles.
So It looks like Tanita includes cardiac and digestive muscles and the water contained in these muscles where Garmin states it does not include cardiac or smooth muscle, which contract without conscious thought.
