Definition of Anthropometry

The part of anthropology (study of humans) with measurements of the human body to dedifferences in races, individuals, etc (Webs20th Century Dictionary, 1970).

Anthropometry is a science that deals with tmeasurement of size, weight, and proportionhuman body. It is empirical (experimentally nature and has developed quantitative metho

various physical dimensions.(Chaffin, 1984)

Anthropos

= human

Metron =measure

Type of anthropometric data Structural body dimension

Measure the body dimensions ofsubjects in fixed (static) positions.

Measurement are made from oneclearly identifiable anatomicallandmark to another or to a fixedpoint in space.

Example : height of the poplitealabove the floor.

What are the applications ofstructural anthropometric data indesign?

Functional body dimensio Measure the body dimens

subjects in dynamic posit Measure the movement o

part with respect to a fixereference point.

Example : maximum forwa

of standing subjects. What are the applications

functional anthropometricdesign?

ethnic? By job?)

Measurement

Recording table

Measurement Read the

instructions

carefully!

Person who

measure should

be understand

the standard of

body dimension.

Data Tabulation(1) Re-check the

data (have

followed the

normal

distribution or

not).

Calculate mean

per dimension.

Calculate

standard

deviation per

dimension.

Data Tabulation(2) Select required

percentile factor.

Calculate data

with its percentile

factor.

Data Tabulation(1-2)Frequency distribution of

body height (stature) in

Americans.

About 95% of all males

are between 162 and 188

cm tall, about 2.5% are

shorter, another 2.5%

taller (Kroemer, 1997).

Case Study :Dari hasil pengukuran tubuh manusia Indonesia (dewasa, laki

usia 19 40 tahun) diperoleh data yang berdistribusi normaldengan tinggi rata-rata 170 cm dgn standar deviasi 7 cm.Berapakah ukuran 95th dan 5th percentile?

95th percentile := X + 1,64 SD= 170 + 1,64 (7)

= 182 cm

5th percentile= X 1,64 SD= 170 1,645 (7)

= 159 cm
