Abstract:
The article presents the results of a study of the dynamics of growth of functional components of special
indicators in 15-16-year-old volleyball players. The purpose of the study was to determine the effectiveness of a
specially developed training method aimed at developing functional endurance, coordination and strength. The
study was conducted for 12 months with the participation of 60 athletes divided into control and experimental
groups. Analysis of the results showed a significant improvement in the performance of athletes in the
experimental group compared to the control group. Quantitative data confirming the effectiveness of the
developed program are presented.
Keywords:
Volleyball, special performance, young athletes, functional components, physical training, endurance.
Introduction:
In recent years, it has become a tradition
to attract young and teenage players (from 15-16 years
old) with high physical and technical-tactical training to
professional volleyball sections. In most cases, such
problems arise that children involved in professional
volleyball, although talented and possessing high skills,
cannot withstand intense loads due to insufficient
physical and functional readiness, as a result of which
both talent and skill are tested. Therefore, it is
advisable to study such problems in annual training
cycles using current research and eliminate them based
on the results obtained.
METHOD
According to the conclusions of leading experts and
scientists who have conducted many fundamental
studies on the theory and methodology of sports
training and created scientific and theoretical concepts
and methodological laws within the framework of
training highly qualified, competitive athletes,
achieving high results in sports practice can be
achieved by using types of training (physical, technical-
tactical, psychofunctional) in a proportional order, in an
integrated direction, increasing the volume and
intensity of loads in accordance with the possibilities,
and taking measures to restore and strengthen working
capacity
in
a
timely
manner.
[1,2,3,4,5,6,7,8,9,10,11,12,13,14].
These authors argue that failure to comply with the
above-mentioned methodological laws, procedures
and principles is likely to “destroy” existing technical
skills. Therefore, even if technical and tactical methods
are improved with the help of appropriate exercise
sets, if their effectiveness or indicators (accuracy,
number of repetitions, speed, etc.) fall below model
indicators and normative requirements for a certain
period of time, then it is possible to assume that the
traditional training or appropriate exercise sets used do
not have sufficient impact value.
RESULTS AND DISCUSSION
According to our physiologists (Khalilov E.Kh.,
Zaynabiddinov A.E., Khushmatov Sh.S. 2020. -330.),
hereditary factors affect the level of development of
physical qualities. Due to the strong influence of
heredity on the div's agility, flexibility, speed-
strength qualities, they develop slowly. Some
physiological indicators, including maximum oxygen
consumption, anaerobic capacity, maximum heart rate,
increased lung capacity, etc., depend on heredity [15].

1. Heart rate (beats/min): experimental group (tg): the
rate of high short-term speed performance decreased
from 69 to 66.8 beats/min (-2.2 beats/min, p<0.05).
This probably reflects changes in the intensity and
pattern of training, aimed at optimizing the div's
energy expenditure. Control group (ng): this indicator
decreased from 68.5 to 67 beats/min (-1.5 beats/min,
p<0.05), a statistically significant decrease was also
observed in this group, but the degree of decrease was
not as great as in the experimental group.
2. Systolic pressure (mm/s.u.): Experimental group
(TG): Systolic pressure decreased from 125.6 mm/s.u.
to 123.4 mm/s.u. (-2.2 mm/s.u., p<0.05). This change
may be related to blood pressure regulation and the
div's adaptation to intense physical exercise. Control
group (CG): In this group, systolic pressure decreased
from 125.8 mm/s.u. to 124.4 mm/s.u. (-1.4 mm/s.u.,
p>0.05), this change is not statistically significant.
3. Diastolic pressure (mm/s.u.): Experimental group
(TG): Diastolic pressure decreased from 68.3 mm/s.u.
to 66.1 mm/s.u. decreased to (-2.2 mm/s.u., p<0.05).
This result indicates an improvement in the general
condition of the div and a decrease in vascular
resistance. Control group (NG): Diastolic pressure
decreased from 68.6 mm/s.u. to 67.1 mm/s.u. (-1.5
mm/s.u., p>0.05), this change is not statistically
significant.
4. Respiratory rate (noch) (times/min.): experimental
group (tg): respiratory rate decreased from 14.3 times
to 12.1 times (-2.2 times/min., p<0.01). This result
indicates the efficiency of breathing and aerobic
adaptation of muscles. control group (ng): respiratory
rate decreased from 14.3 to 12.9 times (-1.4
times/min., p>0.05), these changes were observed to
be statistically insignificant.
5. Barbell test
–
deep breath and breath hold (sec.):
experimental group (tg): the accumulated breath hold
time in the barbell test increased from 37.7 sec. to 42.8
sec. (+5.1 sec., p<0.001). This change indicates an
improvement in muscle endurance and respiratory
control. control group (ng): this indicator increased
from 37.1 sec. to 38.8 sec. (+1.7 sec., p>0.05), but this
result is much smaller than in the experimental group
and is not statistically significant.

6. Genchi test
–
deep breath and breath hold (sec.):
experimental group (tg): breath hold time in the Genchi
test increased from 24.1 sec. to 27.9 sec. (+3.8 sec.,
p<0.001). This indicates a significant improvement in
respiratory capacity and physical endurance. control
group (ng): this indicator increased from 24.2 sec. to
25.8 sec. (+1.6 sec., p>0.05), but this change is very
small and not statistically significant.

times in total) in the zones 1, 6, 5 (a circle is drawn every 2 meters, the center of the
maximum circle is taken as the target) before and after the experiment in the control
and experimental groups.
The above results show that the athletes in the
experimental group showed significant positive
changes in physical and physiological indicators after
training. For example, high short-term speed and
respiratory indicators improved significantly, and
positive changes were also observed in systolic and
diastolic pressure. This indicates the effectiveness of
the training of the experimental group. Although there
were changes in the control group, they were not
statistically significant, which indicates that the
changes in the experimental group were at a much
higher level.
According to the author, physical exercises or sports
training that are standardized and applied based on a
clearly developed methodology, depending on the
capabilities and conditions of the participants, have
been shown to lead to stability in the norm and growth
in sports. On the contrary, the study showed that the
application of unproven load norms and exercises that
do not take into account the requirements of the norm,
the functional and physical conditions of the athlete,
and the risk of unnecessary risks for the sake of the
result, can lead to athletes who have not yet fully
developed to a state of maximum development, to a
cold from sports, and to an early farewell to sports.
CONCLUSION
The conducted studies have shown that the above
results indicate that the athletes in the experimental
group showed significant positive changes in physical
and physiological indicators after training. For example,
high short-term speed and respiratory indicators
improved significantly, and positive changes were also
observed in systolic and diastolic pressure. This
indicates the effectiveness of the training of the
experimental group. Although there were changes in
the control group, they were not statistically
significant, which indicates that the changes in the
experimental group were at a much higher level.
