Body Mass Index BMI

The body mass index (BMI) is a measure that sets the weight in relation to the square of the body size. The BMI is a rough guideline because it covers neither stature nor weight distribution. Since the early 1980s, the BMI is also used by the World Health Organization. The interpretation of the calculated BMI value is based on the comparison with the tabulated average values of the population. That the normal range corresponds to the average in the population at the time of the survey.

Measurement of the waist:

Find the top of your hipbone and the bottom of your ribs. Exhale normally. Place the measuring tape in the middle between these points and wrap it around your waist.

Body Shape Index ABSI

The Body Shape Index (BSI) or more precisely the A Body Shape Index (ABSI) can be considered as a refinement of the Body Mass Index (BMI). The ABSI differs essentially from the BMI by considering the waist circumference in addition to weight and height. The calculated ABSI says something about the body schema distribution. The higher the ABSI, the higher the percentage of belly fat in relation to other parts of the body such as muscles or subcutaneous fat on the arms, legs or upper body.

Ponderal Index

The Ponderal Index, also called Rohrer Index, is a measure of body weight (physically correct body mass) in relation to height, similar to body mass index. In contrast to this, however, the mass m is divided by the third power of the body size l, that is to say referred to a (fictitious) volume instead of an area.

Broca Index

The Broca Index is a measure of the normal weight of a person. The Broca index only allows a rough assessment and is best for the mid-height range; with very large and very small body sizes, the BMI is a bit more accurate.

Waist-size ratio

Measurement of the hip circumference:

Your waist is the narrowest part of your torso. The hips are underneath and they are usually wider than your waist. The measurement of the hip includes the buttocks. The hip measurement should be measured where your hips are widest. The hip represents the largest circumference in your lower body.

Measurement of the neck circumference:

Wrap the measuring tape around your neck and start about three centimeters before the meeting of neck and shoulders. This can also coincide with the lower part of your Adam's apple. Come completely around the neck and do not leave any space between neck and band. Do not over tighten to create unnecessary tension, just so that you get a true measurement. Make sure the tape is horizontal and not held at an angle.

Body fat percentage KFA

Calculation of body fat percentage using the Navy and YMCA methods.

Here, a body fat content may be indicated when e.g. from a body fat measurement a more accurate value than the calculated one is known. By default, the calculated KFA is used according to the Navy method.

Fat-free mass index FFMI

The Fat Free Mass Index (FFMI) is an index that goes beyond the simple BMI. The BMI does not consider how the weight comes about, whether through muscle or fat. The FFMI is more meaningful here, as it takes into account the body fat percentage. A high FFMI signals a good state of training so a high muscle content. The upper limit for the FFMI is 25 for men and 22 for women. Thus, one can read off the potential that can be achieved through training and nutrition in one's own FFMI. Men should aim for a FFMI over 20 and women over 17.
