4.Muscle mass (SLM):
Muscle is a tissue that maintains body temperature and body movements, as well as maintains
heart beats and creates energy. It plays a very important role. The muscle mass includes values of
skeletal muscle, smooth muscle (viscera, etc.) and water content.
Principle of muscle mass acquisition: BIA (bioelectrical impedance method) is used to measure the
body impedance value. Muscles are composed of water and protein, and muscle and bone mass
are combined to be non-fat. The calculation formula for the muscles is derived from the difference
in conduction resistance between the weak currents in the muscles due to age and gender. From
the statistics, people will grow until they reach the age of 20, and then they will gradually decrease
after the maintenance period.
5.Bone mass (MSW): The human bones continue to metabolism, through the intake of calcium to
maintain bone growth and development. The relationship between bones and muscles is very
close. Too thin or underactive will result in a decrease in bone mass. The principle of bone mass
acquisition is a statistically estimated value based on the correlation of non-fat mass (tissue other
than fat). Namely: MSW (bone mass) = LBM (degreasing body weight) - SLM (muscle mass).
6.Basal Metabolic Rate (BMR): Basal metabolism (BM) refers to the minimum energy requirement
required by all organs of the human body to sustain life. The basal metabolic rate refers to the
energy metabolism rate of the human body when it is awake and extremely quiet, and is not
affected by muscle activity, environmental temperature, food and mental stress.
Basal metabolism is determined by the amount of muscle in the individual and is determined by
how much muscle is consumed. That is, the basal metabolic rate can be derived from the content
of human muscle. Usually, the basal metabolic rate accounts for about 70% of the total energy
consumed in one day, and the activity metabolism is added to the basal metabolic amount during
exercise (including daily housework). The basal metabolic rate is determined by how much energy
is consumed by the individual's muscle mass. People with less body fat and more muscles have
higher basal metabolism and consume more energy. Exercise muscle can increase basal
metabolism. People with high muscle mass and high basal metabolism will not have a tendency to
become fat. Conversely, low basal metabolism tends to accumulate fat and become a cause of
obesity. When people are chronically hungry or malnourished, the basal metabolic rate will be low.
