When combined with height measurement, weight can be used to calculate body mass index (BMI) which can give an initial assessment of a person’s physical and nutritional status.
Body Mass Index
Body Mass Index (BMI) indicates the ratio between a person’s weight and height. The more accurately weight and height are measured, the more accurate BMI will be. BMI does not allow any conclusions to be drawn about body composition or the distribution of muscle, fat and water in the body.
Fat Mass Percentage
To compensate for the weakness of the BMI, fat mass must be considered in addition to muscle mass. Fat mass, not weight, is the risk factor for diabetes or cardiovascular disease. Percentage-based fat mass indicates the proportion of fat mass making up body weight.
Visceral Adipose Tissue
It is not just fat mass alone, but also the distribution of adipose tissue which plays an important role in assessing the risk of diabetes or cardiovascular disease. The visceral adipose tissue surrounding the abdominal organs, in particular, has a major influence on the body’s resistance to insulin and thus on the development of diabetes. A high level of visceral adipose tissue is therefore a risk factor and should be as low as possible.
Waist Circumference is a simple measured value which allows visceral adipose tissue to be determined more precisely.
Skeletal Muscle Mass
The skeletal muscles are the muscles which are used actively to move the body. Skeletal Muscle Mass is the weight of all the skeletal muscles in the arms, legs and torso. This value allows a statement to be made about the ratio of fat to muscle. All the skeletal muscles of the user are compared to those of people of the same ethnicity, gender, age and BMI.
Segmental Skeletal Muscle Mass
Segmental Skeletal Muscle Mass indicates muscle mass in the arms, legs and torso. These values allow symmetrical or poor muscle distribution to be identified, enabling personalized training programs, as well as individual targets, to be used in such cases.
Body Composition Chart
The Body Composition Chart combines fat mass and skeletal muscle mass in a coordinate system. A distinction is made between the 4 types of body composition: 1) Slender, lean people 2) Muscular athletes and people who practice a lot of sport 3) Active people with obesity 4) Passive people with obesity, known as “sarcopenic obesity”.
