members of the society and it could be expressed as a morality, ethics or
a popular opinion and behaviour. Existence of the high culture of health
and education turns the individual into more useful for the society and
for itself, helps it to develop itself and to become perfect in harmony
with the environment and with the requirements of its own nature.
The physical development
includes the processes of growth,
development and maturing and is determined by the condition of the
structure, morphologic and functional characterizations of the organism,
which are in the basis of the development of the age of the individual.
There are two groups used as indicators to measure and evaluate it:
1)
anthropometric
- on their part are divided into somatoscopic,
somatic and physiometric and
2)
biological age
indicators including: dental and bone age
indicators and virility indicators.
The physical growth is determined by the influence of internal factors
inheritable, innate, hormonal,
metabolic, and by extraneous factors of
feeding, engaging in sports, etc.
An important regulator and stimulator of the physical
development is the
systematic motive activity and engaging in sports of
the growing up.
The motive activity is a physiological need of the
organism as well as the air, nutrition and water. The positive effects for
the organism in result of the systematic motive activity and engaging in
sports are outlined in three directions:
generally developing effects,
recovering strengthening and educational
.
For example,
the energetic
motive action leads to considerable changes of the support-motive
system the bone growth rate and the constructing of bone
microstructure, there are higher height indicators, bodily mass, mass of
the skeleton muscularity etc. Concerning the heart system the positive
effects consists of improvement of the heart blood irrigation at the
expense of the capillary network, increased heart mass, the percussive
capacity, the values of the pulse frequency and of the maximum arterial
blood pressure are lowered which leads to
more effective and frugal
heart activity.
The above mentioned norms for twenty-four-hour motive activity
ensure to the growing up organism above all strong and harmonious
body development, emotional equability, high efficiency and good
health. If the implementation of the norms is under 50 % then the
condition of motive deficit occurs. When the latter becomes chronic and
151
is accumulated in the organism,
a hypodynamya condition occurs,
considered a pre-morbid one and a significant risk factor for many
diseases. It consists in low steadiness and resistance of the organism,
getting fat, degraded functional possibilities of the organs and of the
systems of the organism, low resistance, adaptive and protective
abilities,
anxiety and depression, decreased activity, general condition
and mood of the individual, etc.
