Dynamics of
regulatory systems activity, caused by cold - hypoxi - hypercapnic influence
The work was done on the
base of biological - geographical
faculty of E.A.Buketov Karaganda State
University within the limits of the cooperation agreement with biological -
soil faculty of St.Petersburg State University. The technique of cold - hypoxi - hypercapnic influences (CHI)
has been kindly given to the laboratory for introduction by authors of the
patent [1].
40 students took part in research, at the age of 17 - 22 years which do
not have expressed infringements in a health state. Students were divided into
2 groups: 1st group -
students from ecologically safe area (South – East part of Karaganda), the 2nd group - the students constantly living in
Temirtau where the powerful industrial complex "Mittal Steel
Temirtau" located in city boundaries.
Students were investigated on the type of regulatory systems response on
diving reaction under CHI.
Diving represents a difficult complex of one-stage influence on an
organism of several factors - hypoxia, hypercapnia, colds. The major point of diving reactions is
a reflex bradycardia. The latent period of a bradycardia is defined first of
all by a threshold of tactile sensitivity and temperature receptors of nasal
meatus and face, and also size of sympathetic influences on heart at the moment
of immersing. Essential influence on this parameter the emotional factor can
cause [2].
On the data received during carrying out CHI it was found out that the
17 % of students from the 1st
group belong to high reactive type of response, among students of the 2nd
group - 64 %. 66 % of students from control group belong to reactive type, and
from Temirtau - only 18 %. Accordingly equal percent of students, about 17 %
and 18 % of investigated 1st and 2nd groups belong to
areactive type of response.
For people with high reactive response type, and such ones were more in 3,5 times in group 2 in comparison with the control, fast
development of a bradycardia, but not high duration of apnoea is characteristic. The short
latent period of development and high speed of bradycardia increase testify to
a low threshold of activation tactile and cold receptors of the face and nasal
meatus that is characteristic for activization of a sympathetic link of
vegetative nervous system and is an indirect indicator of intensity regulatory
systems.
For reactive type the gradual development of bradycardia and rather long
apnoea are typical. The
long latent period of development of a bradycardia and gradual character of its
development testify to a high threshold of tactile and cold skin receptors, and
as a whole about stability of an organism to a cold and less expressed
intensity regulatory systems.
The areactive type of response
meeting enough seldom, representing by
absence of any changes in reply to CHI and characterised by a high threshold of
activation cold face skin receptors, chemoreceptor of vascular channel and low
sensitivity to the raised concentration of coal acid. In our research the
similar type of reaction was marked in both groups of students in small percent
of cases.
Proceeding from the received data, it is possible to assert, that the
students in experimental group (of Temirtau) have high reactive reaction type,
the intensive regulatory systems
apparently caused by negative factors of environment are observed. It was the basis
for carrying out training by means of CHI. After carrying out the training
following results have been received. In the group of students from
ecologically unsuccessful regions the distribution by the type of reaction had
some changes and had following type: the quantity of students with reactive
type has increased in 2 times and has made 36 %. The number of students with
high reactive type remained without changes. Students with areactive type of
reponse after 3 weeks of CHI trainings
were not found out.
In control group the distribution on types of reaction after training
process also had essential change. So, the number of students with high
reactive response type decreased for 7 % from initial and made 10 %. The number
of students with reactive type of response made 90 %, that 24 % more than
reference value. As well as in skilled group, in the control after trainings
the students with areactive type of reaction were not found.
Thus, long training process
improves a condition of functional systems and reduces an activation threshold
of cold receptors of a face skin and nasal meatus that explains absence of
students with areactive type and their transition in group with reactive type
of reaction. Thus, efficiency of training by CHI is more expressed at students
from safe region.
