Antropometrické metody používané
v biologické antropologii
Pavel Bláha
Anthropometrical assessment is
a scientific specialization concerned with the
application of measurement to appraise
human size, shape, proportion, composition,
maturation and gross function.
It is a basic discipline for problem-solving in
matters related to growth, exercise,
performance and nutrition.
The area has been defined as the quantitative
interface between anatomy and physiology.
It puts the individual athlete into objective
focus and provides a clear appraisal of his
or her structural status at any given time,
or, more importantly, provides for
quantification of differential growth.
There are plenty of methods used in distinguished
countries. Martin-Saller method (Lehrbuch der
Antropologie,1957) is mostly being used in middle
Europe and other countries.
Anthropometry appears deceptively simple.
Mastery, however, is somewhat analogous to
playing a musical instrument with style and grace.
With some formal training and persistent practice,
it can be easy and enjoyable and can produce
amazingly accurate data. The development of an
anthropometrist’s touch is seldom achieved without
extensive practice.
It varies from individual to individual, but most
seem to achieve reasonable competence after
triple-measurement and spot-checking for
systematic error with criterion anthropometry
measures on 100 or more subjects.
A “criterion anthropometrist”, by definition,
is one who purportedly does not make systematic
errors from a prescribed technique.
In assessing individual status with respect to a particular
norm, it is necessary that a high level of precision
and accuracy be attained by the measurer.
Precision is a matter of how consistent a measurer is
with him or herself (intra-observer reliability) or with
other measurers (inter-observer reliability).
Accuracy is a matter of how closely obtained measures
conform to true or ideal measures. In the measurement
sequence, only right side values of the subject are taken
in surveys. When there is a question of bilateral
asymmetry, however, both sides should be taken.

Methods of classical anthropometry hold and
important place in common routine practice
because they are non-invasive, relatively
cheap, saving time and suitable for field work.
We use two basic ways of anthropometric
measurement of living persons:
cephalic parameters
body parameters
a) Hlavové rozměry jsou důležité pro posouzení růstu
hlavy, především v období od narození do 6 let věku dítěte.
Využití: plastická chirurgie, stomatologie, stomatochirurgie.
b) Tělesné rozměry jsou důležité pro monitorování
růstu, stanovení komponent tělesného složení
(Matiegkovy rovnice, metoda Drinkwatera-Rosse),
stanovení somatotypu (Heath-Carter method),
posouzení proporcionality jednotlivce (např. Z-score,
Percalovy indexy, vypracování referenčních standard).
Využití: pediatrie, endokrinoloige , obezitologie,
ortopedie, ergonomie, sportovní antropologie atd.
Segment lengths
General technique: The segmometer housing is held
in the right hand throughout all the direct
length measurements. The lengths are measured with
the tape parallel to the long axis of a bone
or body segment. The tape is held so the ends of the
cotter pins are in contact with the marked sites at
the end of each segment or length and the reading is
taken at the edge of the housing end cotter pin,
at the side to which the bevel runs upward,
to the nearest 0.1 cm.
Selected cephalic points
GLABELLA (g)
Glabella is the most prominent midline point
above the nasal root, on the lower part of the
forehead between the eyebrows.
NASION (n)
Nasion is the point in the midline of the
nasofrontal suture. The slight ridge on which
it is situated can be felt by an observer’s
fingernail.
EURYON (eu)
Euryon is the most prominent lateral point on
each side of the skull found on the parietal or
temporal bones. It is identified by measuring
the greatest width of the head.
GNATHION (gn)
Gnathion is the lowest median point on the
lower edge of the mandible in the most
anterior position. It is identified by palpation
from below.
OPISTHOCRANION (op)
Opisthocranion is the point situated at the midline
of the occipital bone which is most distant from the
glabella.
ZYGION (zy)
Zygion is the most lateral point of each zygomatic
arc. It is identified by measuring the greatest width
of the face.
FRONTOTEMPORALE (ft)
Frontotemporale is the point on each side of the
forehead, on the linea temporalis most forwards
and closest to the midline, in the place where the
lineas temporalis are closest together.
GONION (go)
Gonion is the most lateral and interior point on the
mandibular angle.

Definition of anthropological points
(landmarks) Because the body can assume
a variety of postures, anthropometric
description is always in reference to the
anatomical position. This is where the
subject is oriented to a standing position

upper limbs hanging by the sides with the
palms forward, thumbs pointing away from
the sides with fingers pointing directly
downward, and the feet together with the
toes pointing directly forward.

Skinfolds thicknessess
The most often used data from athropometric
measurement is that obtained from skinfolds. It has
been very popular to use the sum of varying numbers
of skinfolds to calculate percentage body fat.
Any combination of skinfolds can be used, but if
a realistic assessment of subcutaneous fat is to be
gained, sites must be chosen from both the upper and
lower body. The most commonly used combination
features six sites – triceps, subscapular, supraspinale,
abdominal, front thigh and medial calf.
Mostly used types of caliper are Best and Harpenden
(this type are much variations).
BICEPS SKINFOLD
The caliper is applied 1 cm
distally from the left
thumb and index finger
raising a vertical fold at
the marked midacromiale-radiale line on
the anterior surface of the
right arm
TRICEPS SKINFOLD
The caliper is applied 1 cm
distally from the left thumb
and index finger raising
a vertical fold at the marked
mid-acromiale-radiale line on
the posterior surface of the
right arm.
SUBSCAPULAR SKINFOLD
The caliper is applied 1 cm
distally from the left thumb
and index finger, raising a
fold oblique to the inferior
angle of the scapula in
a direction running obliquely
downwards in a lateral
direction at an angle
of about 45 from the
horizontal along the natural
fold.
SUPRAILIAC SKINFOLD
The caliper is applied 1 cm anteriorly from the left thumb and
index finger raising a fold 3 cm up the border of the ilium
and a line the spinale to the anterior axillary border. The fold
follows the natural fold lines running medially downwards
at a 45 angle from horizontal.
BODY WEIGHING
Our anthropometric examinations
Matiegka´s Equations
90 years ago, the Czechoslovakian anthropologist
Jindřich Matiegka proposed method for the anthropometric
fractionation of body mass into four main components:
• skeletal mass
• fat mass
• muscle mass
• residual or vital organ/visceral mass (Matiegka, 1921).
WHY TO USE Matiegka´s FORMULAS?
1. They are based on European populations.
2. We have proved their usefulness both theoretically
and for practice.
3. The method is non-invasive, easy to use in the field,
suitable for short-time examination of patients and
relatively cheap in use.
4. Matiegka´s formulas are part of a special
anthropological PC programme ANTROPO,
which makes automatic processing of
anthropometric data possible.

The Heath-Carter somatotype methods
A somatotype is a classification of physique based on
the concept of shape, disregarding size.
The pre-eminent system of somatotype classification is
the Heath-Carter somatotype. This shows the relative
dominance of Endomorphy (relative fatness),
Mesomorphy (relative musculo-skeletal robustness)
and Ectomorphy (relative linearity). Each component is
identified in the sequence endomorphy-mesomorphyectomorphy and, when anthropometrically-derived,
expressed to the nearest one-tenth rating,
e.g. 1.4.-6.0-3.2, an ectomorphic mesomorph,
or ecto-mesomorph. Ratings of 2 to 2.5 are considered
low, 3 to 5 are moderate, 5.5 to 7 are high and 7.5
and above are very high (Carter, 1996). The derivation
equations for each component are as follows.
Endomorphy
-0.7182 + 0.1451*∑SF – 0.00068*∑SF2 +
0.0000014*∑SF3
[where ∑SF = sum of triceps, subscapular and
supraspinale skinfolds multiplied by
(170.18/height in cms)]
Mesomorphy
0.858*humerus breadth + 0.601*femur
breadth + 0.188*corrected arm girth +
0.161*corrected calf girth – height*0.131 + 4.5
Ectomorphy
One of three equations is used depending on the value
of the calculated Height Weight Ratio (HWR)
of the subject. [HWR is height/body mass333].
If HWR is greater than, or equal to 40.75 then
ectomorphy = 0.732*HWR – 28.58
If HWR is less than 40.75 and greater than
38.25 then ectomorphy = 0.463*HWR -17.63
If HWR is equal to or less than 38.25
then ectomorphy = 0.1
