Human Height
By Alisha of Jobslover.com
Human is the of a human being. It is highly variable, but normally falls
with a certain range (bell curve). The average for male adults in America is about 5'9"
to 5'10" (175-178 cm). For male teenagers the average is from 5'4" to 5'9" (163-175 cm).
This probably indicated that most adults obtain their full around the late teens. For
female adults in America, the average is 5'3" to 5'8"(160-173 cm). For female teenagers
the average is from 4'11" to 5'6" (150-167 cm).
Human can be changed by many factors. Since the development of modern medicine and
plentiful food in the developed world average has increased dramatically. Nutrition is
the most important factor in height, and records from military records and other
documents can be used to quite accurately compare nutrition in various eras. Evidence has shown
that decreased in Britain in the early nineteenth century, before beginning its long
increase around mid-century. Increase in has not been constant, however. The European
Dark Ages were an era of considerable with men of above six feet (183 cm) considered
unremarkable. In Europe human reached its nadir at the start of the nineteenth century.
The average in Napoleon's army was about five feet (152 cm). Until the general rise in
human health the general trend was as urbanization increased declined.
Americans were far taller in the nineteenth century, the tallest in the world. However since
the Second World War the of Europeans have grown to surpass Americans by a fair margin,
and has shown no sign of slowing. For instance the Netherlands was in the late nineteenth
century a land renown for its short population, but today it has one of the tallest averages in
the world with men averaging 6'2" (187 cm) tall. The average in East Asian nations has
been growing even faster and is likely to pass that of the United States in the near future.
Japanese, once known in the west for shortness, are expected to be taller than Americans within
a decade. Average in impoverished Vietnam and North Korea remains very small (5'4"/162.5
cm and 4'11"/150 cm respectively, for young men), especially in contrast to the extreme growth
occurring in surrounding Asian populations with higher standards of living (young South Koreans
are about a foot taller than their North Korean counterparts, on average).
Height has important social ramifications. For men shortness is often a disadvantage with women
finding short men less attractive and other men less likely to respect them. For instance taller
politicians have a tendency to win elections. Studies have found taller men marry earlier and
earn higher wages. It is almost the opposite for women where great can be seen as
unattractive.
Height can also play a role in sports. For most sports, is useful as it affects the
leverage between muscle volume and bones towards greater speed of movement. It is perhaps most
valuable in basketball where extreme is a great advantage. In some sports such as horse
riding and gymnastics a compact frame is far more valuable.
The study of human growth is known as auxology. Growth and have long been recognized as
a measure of the health and wellness of individuals, hence part of the reasoning for the use of
growth charts. Genetics is a major factor in determining the of individuals, though it is
less influential in regard to populations. Average is increasingly used as a measure of
the health and wellness of populations.
This is attributed as a significant cause for the trends
of increasing for egalitarian populations where medical care and proper nutrition are
more equally distributed. Diet, exercise, fitness, pollution exposure, sleep patterns, and
climate are other possible factors.
The relationship between genetics and environment is uncertain. Certainly there are substantial
relationships in the general heights of biological families; and the heights of parents and
family are a fairly good predictor for the of their children. However, as cited, there is
strong environmental influence as well. Asian populations were once thought to be inherently
shorter, though it now seems that humans as a species probably have a similar genetic
potential, and it is clear that genotypic size has not yet been realized.
