Background and Study Aim. In the basis of the boxer's power qualities is the ability to perceive and process external information. Therefore, in order to ensure the proper training of qualified boxers, there is a need to monitor the functional state of the boxer’s organism. The relationship between cognitive functions and special working capacity of elite boxers were studied. Material and Methods. The level of special working capacity was studied by the test of punching a boxer for 8 s at maximum speed. Cognitive functions (verbal and nonverbal intelligence, and word memory) were studied using the "Multipsychometer-05" hardware-software. 26 elite boxers, aged 18-24, were tested. Results. The research results showed that groups of boxers with different levels of special working capacity differ in terms of accuracy and efficiency when performing a cognitive task with verbal stimuli. The resulted that the high level of special working capacity of elite boxers is provided by the manifestation of verbal intelligence. Besides, the special working capacity is related with activation of mental functions of attention, speed of visual perception, operational and logical thinking. At the same time, significantly higher values of decision latency in this group of boxers indicate a slowdown in the processing of nonverbal information in boxers with a high level of special working capacity to work. It can be noted that the special working capacity of boxers has a direct relationship with quality and inverse relationship with the speed of information processing. The speed of memorizing verbal information is better in boxers with a high level of special working capacity. This fact indicates the importance of the verbal factor for the assimilation of special information in the training of boxers. The best values of accuracy and efficiency indicate the relationship of special working capacity in skilled boxers with the quality and volume of memorized verbal information. Conclusions. The special working capacity of elite boxers has a direct relationship with quality and inverse relationship with the speed of information processing. The elite boxers with a high level of special working capacity have a better speed of verbal information memorizing.

Background and Study Aim: Special physical preparedness of wrestlers is one of the main factors for achieving the highest possible results in competitive activity. Physical qualities can differ significantly among wrestlers of the same skill level, but different individual styles. In this regard, this study is aimed at improving the methods of special physical training of qualified wrestlers, taking into account individual styles of wrestling. Material and Methods: The study involved 30 wrestlers of middle weight categories (72 kg, 77 kg, 82 kg). The participants were divided into two groups: control group - 15 athletes, average age (18.96±1.09) years, average weight (76.27±5.58) kg; experimental group - 15 people, average age (19.07±0.95) years, average weight (75.87±5.68) kg. All participants belonged to athletes of a high level of skill. Training tasks were developed to improve the methodology of special physical training of wrestlers, taking into account the styles of wrestling. The proposed program was tested in a pedagogical experiment that lasted one year. Significance of differences between groups was assessed using nonparametric signs (z) and Rosenbaum (Q) tests. Results: during the experiment, the increase in the results of special physical preparedness among the wrestlers of the experimental group is much higher in all tests and it is in the range from 6% to 14%, and in the control group it is lower - from 2% to 3%. Also, these results were confirmed by a non-parametric criterion of signs. So, the wrestlers of the experimental group at the end of the experiment showed an improvement in performance. A significant increase in the results in the «Pull up» test was shown (z=1; p<0.01). The time to complete the tests significantly decreased: «10 back arch throws» (z=0; p<0.01), «10 suplexes» (z=0; p<0.01), «Flips on the gymnastic “bridge”» (z=0; p <0.01), «Running on the wrestling “Bridge”» (z=0; p<0.01), «10 forward somersaults» (z=0; p<0.01), «Three series of 15 back arch throws» (z=3; p0.05), «Push-up in 20 s» (z=4; р>0.05). Conclusions: The fulfillment of the developed training tasks by the wrestlers of the experimental group made it possible at the end of the experiment to show significantly better results in terms of special physical fitness than the athletes of the control group (p<0.05-0.01). Such results testify to the effectiveness of the proposed methodology and the possibility of its implementation in the training process.

Purpose: to conduct a comparative analysis of the indicators of competitive activity at the world championships among wrestlers of different age groups. Material and methods. The analysis of protocols and video recordings of the world championships (WC) among adults in Belgrade (Serbia) and U-23 in Tirana (Albania) was conducted. A total of 614 matchеs were analyzed: at the U-23 World Championship (n=243) and at the World Championship among adults (n=371). The initial data of the athletes' performances were taken from the website of the international wrestling federation UWW. The analysis of competitive activity was carried out using the internet platform (Performance Data Analysis - PDA). Statistical analysis of the data was carried out using licensed Excel spreadsheet packages. For categorical data, the results were expressed in absolute numbers (number of times) and percentages (%). To compare the indicators of the wrestlers' competitive activity, the Student's t-test was used, the extraction was considered reliable at (p0,05) are observed in all effective TTАs performed by wrestlers at the 2023 World Championships among adults and U-23. It was established that the number of points scored is higher in the standing position than in the ground position and the number of technical points is higher than non-technical at both world championships. It is worth noting that the percentage of technical points is higher at the U-23 World Championships (71,83 %) than at the Adult World Championships (66,98 %), but this difference is not significant (p>0,05). It was determined that the largest number of points scored falls on the second minute of the match, and the smallest – on the sixth minute of the match, both at the U-23 World Championships and the Adult World Championships. It is worth noting that older wrestlers have higher performance in the fourth and fifth minutes of the match, but this difference is not significant (p>0,05). The average number of points scored per match is significantly higher (p<0,05) for wrestlers at the U-23 World Championships. This indicator significantly increases the spectacle of Greco-Roman wrestling. Another important indicator that determines the spectacle of the match is the success index. It is also the largest at the U-23 World Championships and this difference is significantly better (p<0,05).Conclusions. The conducted studies indicate some similarities and differences in the indicators of competitive activity of Greco-Roman wrestlers at the adult and U-23 world championships. Similarities: conducting simple (one-point, two-point) technical and tactical actions; a large number of matchеs that ended with a score of 1:1; many stops in the match (challenge, violation of the rules). This negatively affects the spectacle. Differences: the average number of points scored in matchеs and the success index are significantly higher (p<0.05) in wrestlers at the U-23 World Championships. It was determined that Greco-Roman wrestling requires adjustment of the competition rules.

Purpose. To study the main causes of functional overstrain in military personnel with musculoskeletal injuries of the limbs during long-term rehabilitation while applying standard physical therapy protocols. Material & Methods. 56 military personnel who had sustained musculoskeletal injuries of the limbs 16 months earlier as a result of mine-explosive and gunshot wounds were examined. During the previous 10 months of long-term rehabilitation, standard physical therapy protocols were used according to the specific nosology. The participants were divided into groups and subgroups according to their nosology and type of heart rhythm regulation. Test load 1 was developed for servicemen with upper limb injuries, and test load 2 – for military personnel with lower limb injuries. To assess the adaptive and compensatory responses of the participants to the test loads, indicators of heart rate spectral analysis and blood biomarkers (creatine phosphokinase, lactate dehydrogenase, testosterone, and cortisol) were used. Monitoring of possible adaptive changes was carried out before and after 15 days of using physical therapy protocols under the supervision of rehabilitation specialists. Results. At the beginning of the study, regardless of the nosology, a shift in autonomic balance was simultaneously observed toward both sympathetic and parasympathetic activity. In 50% of the examined participants, an enhancement of the central contour of sinus rhythm regulation was observed along with decreased cortisol concentration and increased LDH activity in the blood. Such adaptive-compensatory responses to a stress stimulus indicate low muscle glycogen reserves and an insufficient level of resistance, reflecting a state of non-functional overstrain and a risk of adaptive failure. Other study participants had a decrease in the influence of the central contour, accompanied by opposite changes in the LF/HF ratio. CPK levels increased significantly, and blood cortisol concentration almost reached the upper limit of normal, indicating a state of functional overstrain. The results obtained after 15 days of using the prescribed physical therapy protocols under the supervision of rehabilitation specialists showed almost identical changes in HRV indicators and blood biomarkers as those observed at the beginning of the study. Such prolonged changes in biomarkers indicate a continuously progressing depletion of adaptive reserves due to compensatory reactions triggered by excessive stress stimuli. Conclusions. Using inpatient rehabilitation services by military personnel over the previous 10 months led to the development of a state of non-functional overstrain in 50% of the examined individuals. A re-examination conducted over 15 days in inpatient conditions, concerning the influence of physical therapy protocols recommended by physical rehabilitation specialists on the neuromuscular system readaptation, confirmed the previous results. The study results allowed for a clear identification of the main problems causing the FOR and NFOR state development in military personnel with these nosologies, and the necessity of using a wide range of biomarkers to assess their adaptive and compensatory responses to physical load.
