Sensorimotor Indicators as Criteria of the Intense Physical Loads Influence on the Athlete's Body

Characterization of the Influence of Physical Rehabilitation Means and Special Physical Exercises of Archery on the Sports Performance of Paralympic Athletes

“…The analysis of the scientific literature showed that the goal of archery training is the formation of stable, stable, controlled depending on the conditions of archery, and motor skills archery shooting [1,3,6,7,13]. Data on the mechanisms of the formation of motor activity -"shooting from a bow" can be used as a convenient model for the analysis of similar processes in other sports with a discrete nature of the result, a complex coordination structure of motor skills, in which the main mechanism for achieving the optimal result is a high muscle articular sensitivity of the upper limbs, a high capacity for afferent synthesis and decision-making in a micro-interval of time sufficient to maintain the "shooter-bow" system in a state that corresponds to hitting the top ten.…”

The essence of the long-term training of archers can be reduced to a short work task: always shoot so as to hit the top ten [1,2,3,6,7]. On the way to the realization of this task, there are functional barriers in the form of natural variability of the functional state of the central nervous system (for example, the phase of alpha waves), different levels of excitability of the neuromuscular apparatus (motor units, neuromuscular synapses) of the heart -vascular and other systems that change their functional state during the repeated repetition of skills both during one day and during many weeks and months of training [2,3,4,5,6,7,9,11].…”

Predicting the direction of these changes, their number, and their impact on the athlete's performance is one of the most important tasks of effective training.…”

Sensorimotor Criteria for the Formation of the Autonomic Overstrain of the Athletes’ Cardiovascular System

“…Determination of sensorimotor function is an important area of psychophysiological features study of the athletes body (Berdychevskaia, Troiskaia, & Fokin, 2009;Craig, 2005), which are essential for the analysis of cognitive processes (Oppenheimer, Gelb, Girvin, & Hachinski, 1992), assessment of the central nervous system (CNS) functional state, sensory sensitivity (Guzii, Romanchuk, & Мahlovanyy, 2020;Noskin et al, 2005), development of motor skills, psychophysiological and neurophysiological parameters of brain functioning (Boloban, 2006;Kuznetsova, Sychov, & Еgоrоvа, 2017). A large number of scientific publications are devoted to the study of simple and complex sensorimotor reactions of athletes, which are aimed at determining the characteristics of the organization of sensorimotor function taking into account the type of sport, gender, training experience, stages of the training process, etc.…”

“…Among the components of the "reaction time", the parameter characterizing the central level of organization of movements is the speed of processing information in the CNS with the decision to respond to a signal. That is why our attention was drawn to the method of estimating the sensorimotor function using the "Computer Motion Meter" (CMM-03), which is distinguished by the indicator of switching central settings (SCS), which characterizes the central level of regulation of movements, namely the time of decision about changing the characteristics of motion (Guzii et al, 2020;Korobeynikov & Korobeynikova, 2014). The aim of the study.…”
