It is widely used internationally because it has a lot to do with the amount of fat contained in the body. Judgement standard:
Thin Standard Overweight Obesity WHO evaluation criteria BMI18.5 18.5BMI25.0 25.0BMI30.0 BMI30.0 2.Body fat percentage (BFR):
The body fat percentage is the proportion of body fat in body weight. It should be judged from the body fat rate whether it is obese or not, not only based on body weight. Principle of parameter acquisition: BIA (bioelectrical impedance analysis) is used to measure the impedance value of the human body, and then the fat content is calculated. The tissue that is easily conductive in human tissues is water-rich tissues (such as muscles and blood vessels), and the adipose tissue is almost non-conductive. It is the use of different electrodes to send a weak current to the human body, and then to measure the body resistance, using the difference in impedance between the body's fat and non-fat tissue, to calculate the body composition. Excessive body fat can cause: cancer, diabetes, high blood pressure, cardiovascular disease and other diseases.

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. Male Female Height Muscle mass Height Muscle mass Less than 160cm 160 - 170cm 170cm or more 38.5 - 46.5kg Less than 150cm 21.9 - 34.7kg 44 - 52.4kg 49.4 - 59.4kg 150 - 160cm 32.9 - 37. 5kg 160cm or more 36.5 - 42.5kg 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). Male Female Body weight Bone mass Less than 60kg 2.5kg 60 75kg 75kg or more 2.9kg 3.2kg Body weight Bone mass Less than 45kg 1.8kg 45 60kg 60kg or more 2.2kg 2.5kg 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. 11 Body composition index Male Standard weight(Kg) 64.7 67 62.5 56.7 BMR 1550 1500 1350 1220 Age 18-29 30-49 50-69 Over 70 Female Standard weight(Kg) 51.2 54.2 53.8 48.7 BMR 1210 1170 1110 1010 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. Normal range of body water Male 45---------60 Female 50--------65 12 Body composition index 10.Visceral fat grade (VFR): The fat attached to the visceral gap in the abdominal cavity is called visceral fat. Visceral fat is generally expressed in grades, and level 10 is equivalent to a visceral fat area of 100 square centimeters. Excessive visceral fat can lead to high blood lipids, arteriosclerosis, hypertension, myocardial infarction, cerebral thrombosis, cerebral hemorrhage, diabetes, fatty liver and other lifestyle-related diseases. Determination Health
(1---4.5) Warning
(5---9.5 ) Slightly more
(10-14.5) Dangerous
(15 or higher) Don't worry now, you should continue to maintain a balanced diet and moderate exercise. To exercise the right amount of exercise, control the amount of calories ingested and work toward standard visceral fat levels. To strengthen the amount of exercise, pay more attention to control diet, reduce the intake of calories. It is necessary to actively participate in exercise and reduce calorie intake. Please consult a doctor for medical diagnosis. 11.Body composition score (Score): A score (0-100) based on a comprehensive evaluation of each component of the body. BMI (40%), fat percentage (40%), and muscle rate (10%) were the main scoring factors (other factors accounted for approximately 10%). The higher the score, the better the physical condition and the closer to the healthiest body. Principle: The main parameters of physical condition assessment are BMI, body fat percentage, muscle mass and other parameters, assuming 100 points for the most standard range of each parameter, then the scores exceeding and below the standard range are decremented accordingly (set the decreasing gradient), then The weight is set according to the influence degree of each parameter on the physical condition, and the comprehensive score is the final score. 12.Protein content (PM): Protein is an important component of all cells and tissues in the human body. Protein is related to life phenomena. Protein content is strongly correlated with muscle mass. Protein acquisition is obtained by the following relationship: muscle = water content + protein content.

Normal range Overnutrition 13.Lean body mass (LBM): The weight of the body that removes fat. It is inversely proportional to the amount of fat. Principle of parameter acquisition: Calculated according to the relationship between lean body mass and body weight and fat: LBM (lean body weight) = Wt (body weight) -
