7.Body age:
In vivo age is the body age tendency given by the basal metabolism of body weight. The same
body weight and body composition will vary in age. The amount of muscle is high, and the person
with high basal metabolism is younger, and vice versa.
8.Water content (TF)
Body water refers to blood, lymph, extracellular fluid, intracellular fluid, etc., which contain water in
the body. It has important functions such as transporting nutrients, recycling waste in the body, and
maintaining body temperature. Water content acquisition principle: BIA (bioelectrical impedance
method) is used to measure the body impedance value. When the weak current passes through
the human body, the water conductivity is good, so the formula for calculating the water amount
can be derived from the measured impedance value((Total body water estimation usingbioelectical
impedance:ameta-analysis of the data availablein the literature,Acta Disabetologi-
ca,2003,Vol.2003,vol.40(1),pp.s203-s206)).
9.Body water percentage (TFR): The water rate is higher in men than in women, and tends to
decrease with age. People with more body fat have less water. During the day, the water rate
changes due to water intake, physical activity, and poor health. Algorithmically, height, weight, age,
gender, and impedance all have an effect on moisture content. Body water refers to the body's
water, including blood, lymph, extracellular fluid and other ingredients. It has important functions
such as transporting nutrients, recycling waste, and protecting body temperature.
