- The influence of morphological signs on the level of physical fitness has not been sufficiently
studied.
Systematic physical exercises increase the adaptive reactions of the body, cause its proper
functioning. Reactions to physical activity do not go unnoticed: they are accompanied by specific
trace shifts (trophic processes), on the basis of which there is an increase in the structural,
energy, and therefore functional resources of the body. This is an important factor in increasing
the reliable functioning of the physiological systems of the body, which, naturally, becomes
especially important during the development of age-related changes. Provides structural and
functional improvement of blood circulation and enhancement of the trophic functions of the
nervous system, the creation of a sufficient supply of energy, an increase in the capillarization of
the skeletal and cardiac muscles.
The functional reserve increases, adaptation to loads, accelerates recovery. The faster the
recovery, the more the body has the strength to perform the subsequent work, therefore, the
higher its functionality and efficiency, i.e. the operating time is increased and the operating time
is shortened. When doing physical exercises, positive emotions affect the neuropsychic tone,
which, in turn, affects the heart rate. In adolescents engaged in physical exercises, there is a
decrease in the resting heart rate, because As a result of training, there is an addiction, adaptation
of the body to physical activity, respectively, the depth of breathing at rest will be greater, and its
frequency is less frequent, which indicates an increase in VC. The psychomotor function
develops (speed and accuracy of movement). As a rule, those involved in sports are ahead of
their peers in physical development.
In sports practice, the effectiveness of an athlete's technique is monitored and evaluated by its
effectiveness, stability, variability, and economy; minimal tactical information content for the
opponent. The effectiveness of the technique is determined by its compliance with the final
results, compliance with the level of all aspects of preparedness. The stability of the technique is
associated with its opposition to the unaccounted for objective and subjective factors,
independence from external conditions and the athlete's functional state.
It should be borne in mind that modern training and especially competitive activity is
characterized by a large number of confounding factors (fans, judges, etc.). The ability of an
athlete to maintain the basis of the structure of sports equipment in extraordinary conditions is
the main sign of stability and determines the level of technical skill.
The variability of the technique determines the athlete's ability to operatively correct motor
actions, depending on the conditions of the competition. Scientific analysis and sports practice
show that the desire of athletes to maintain the temporal dynamic and spatial characteristics of
movements, that is, the stabilization of the technique does not lead to high results.
Consequently, the purposeful variability of the athlete's technique provides a decrease in the
effect of hindrances to stabilize the result, and this also increases the reliability of the exercise.
From this point of view, it is fair to talk about the variability that stabilizes the athlete's
technique. It has been established that the variability of technique is of greater importance in
sports with an acyclic nature, when a technical action is used in a shortage of time, active
counter-action of opponents, etc.
The efficiency of the technique is characterized by a reserve of energy, that is, by the
recuperation of energy when performing the technique of physical exercises, by the expedient
