Электофизиологические корреляты точности выстрела у лучников разной квалификации

The purpose of this study was to establish electrophysiological markers of archers’ shot accuracy by correlations between performance and electroencephalogram (EEG) power parameters in athletes of different ranks compared. Materials and methods. The research involved 20 archers shooting the classic bow, who were divided into two groups of 10 subjects each by sports rank: Candidate for Master of Sport and First-Class Sportsman. EEG was recorded using the Encephalan-EEGR-19/26 device (Medikom MTD, Taganrog) in 19 leads according to the 10–20 system. Reference electrodes were placed on the earlobes. Results. It was found that shot accuracy of high-level archers (Candidate for Master of Sport) is marked by an increase in alpha and theta EEG power in the occipito-temporal-frontal regions of the left hemisphere during the preparatory phases of the exercise, and then, by the dissociation of the powers of these frequency ranges while aiming. In contrast, shot accuracy of lower level archers is characterized by a decrease in the power of the main rhythm in the left temporal lead during the first phase of the shot. In the total sample of athletes (regardless of rank) no significant correlations were found in any of the 3365 cases of evaluation of this analytical parameter. Thus, the electrophysiological markers of bow shot accuracy differ between Candidates for Master of Sport and First-Class Sportsmen. The sevenfold greater number of significant correlations (p < 0.05) between EEG parameters and shot accuracy of Candidates for Master of Sport compared to First-Class Sportsmen indicates a high level of development of the Bow Shot functional system of purposeful movements as the skill improves, as well as testifies to the synergism of physiological processes when performing the exercise by Candidates for Master of Sport. The established facts will expand coaches’ physiological understanding of the mechanism of purposeful movements in order to objectively predict sports results.

Features of Special Physical Training for Female Athletes in Cossack Fight during Different Phases of a Specific Biological Cycle

Background. The training methods for female athletes’ special physical training are considered to be a crucial aspect of the overall preparation system for competitive activity, which requires correct planning and implementation. Objectives. The study aimed to determine the impact of special preparatory exercises on female athletes engaged in Cossack Fight, depending on the characteristics of the body’s functioning in different phases of a specific biological cycle. Materials and methods. The study involved 20 female athletes aged 17-24 years who participated in Cossack Fight, and were divided into experimental and control groups. The qualification levels of female athletes in the experimental group were as follows: 1 – Master of Sports of Ukraine; 2 – Candidates for Master of Sports of Ukraine; 7 – 1 sports category. The control group comprised: 1 – Master of Sports of Ukraine; 2 – Candidates for Master of Sports of Ukraine; 7 – 1 sports category. The training program lasted for ten weeks and took place at a special preparatory and control-preparatory stage of the preparatory period. Results. The findings showed that the variability of training loads, depending on the phase of the ovarian-menstrual cycle, had a statistically significantly greater impact on the indicators of special physical fitness in the female athletes’ experimental group compared to the control group. Thus, after ten weeks of special physical training, the experimental group demonstrated a significant increase in the number of direct punches on the punching bag in 4 seconds (t=4.07; p<0.001) and 15 seconds (t=3.62; p<0.001), throwing a medicine ball weighing 3 kg (t=2.92; p<0.05), repeated circular kicks on the punching bag to the torso level for 15 seconds (t=4.22; p<0.001), direct punches on the punching bag for 1 minute (t=4.23; p<0.001), repeated circular kicks on the punching bag for 1 minute (t=4.49; p<0.001), and jumping rope after exercise (a 3-minute punching bag workout) for 1 minute (t=3.55; p<0.001). Conclusions. The implementation of an experimental program for special physical training of female athletes, in accordance with the phases of the ovarian-menstrual cycle, into the general system of preparation for competitive activity, leads to a statistically reliable improvement in key indicators of physical fitness.

Gender peculiarities of cortisol, testosterone and vitamin D blood levels in athletes

Objective. To assess the gender characteristics of the concentration of cortisol, testosterone and vitamin D in blood serum in athletes, and to analyze the correlations between vitamin D levels and the hormonal status of athletes. Materials and methods. 52 athletes (32 men and 20 women) were examined, their age was 17-23, their sports specialization was cyclic sports (kayaking) and acyclic sports (gymnastics, martial arts), and qualification – candidates for master of sports, masters of sports. Venous blood was taken in the morning on an empty stomach before training loads. Determination of total testosterone and cortisol concentration and assessment of vitamin D level by determination of its metabolite 25(OH)D (25-hydroxyvitamin D) in blood serum was performed by immunochemiluminescent method. Results. In male athletes with vitamin D deficiency, serum testosterone concentration and anabolic index were significantly lower (p = 0.0093 and p = 0.0015, respectively) compared to the same indices in the group of athletes with normal vitamin D content. Correlation analysis in male athletes revealed a positive correlation between serum 25(OH)D (25-hydroxyvitamin D) content and testosterone concentration (r = 0.36; p < 0.05), as well as between 25(OH)D content and anabolic index (r = 0.42; p < 0.05). The group of female athletes with vitamin D deficiency showed significantly lower serum testosterone concentration compared to athletes with normal vitamin D levels (p = 0.0112). No significant relationships were found between vitamin D levels and cortisol concentrations in both male and female athlete groups. Conclusion. The study results can be the evidence of modulation effect of vitamin D on testosterone levels in male athletes, indicating the importance of controlling and correcting vitamin D content in the dynamics of the training process.

Динаміка показників техніко-тактичної підготовленості дзюдоїстів 19-21 років середніх вагових категорій під впливом запропонованих моделей підготовки

Purpose: to investigate the dynamics of indicators of technical and tactical preparedness of judokas of 19-21 years old of middle weight categories under the influence of the offered models of training. Material and methods. Methods of the research: analysis and generalization of scientific and methodical literature; timekeeping; analysis of protocols and video recordings of fights of judokas of 19-21 years old of weight categories up to 60 kg, up to 66 kg; pedagogical experiment; methods of mathematical statistics. The pedagogical experiment was attended by 20 judokas aged 19-21 years (Candidate for Master of Sports, Master of Sports of Ukraine), who were divided into control and experimental groups of 10 athletes each. We analyzed 60 fights of sportsmen of the experimental and 60 fights of the control groups. Results: after the pedagogical experiment, the number of fights that ended early increased in the judokas of the experimental group (the beginning of the experiment - 66 %, the end - 77 %) and the number of fights within the allotted time and in additional time decreased. This suggests that the fights of the athletes of the experimental group are quite dynamic, and the use of combinations and counterattacks allows to finish the fight before the allotted time. Also, the number of counterattacks and combinations of techniques during fights increased statistically significantly. Thus, the number of application of the combination technique increased from 18 to 23 (t=3,61; p<0,05), and the counterattacking from 21 to 31 (t=5,73; p<0,05). Also, the increase in the total number of real attempts to perform technical actions from 104 to 138 was established. A more detailed analysis showed that in the stand position sportsmen of the experimental group performed a smaller number of real attempts to perform technical actions in comparison with the beginning of the experiment (beginning - 103, the end - 97). Also, there is an increase in the effectiveness of technical actions (beginning - 24 (23 %), end - 35 (36 %)) estimated by judges as a half-victory (beginning - 12, end - 20) and as a pure victory (beginning - 12, end - 15). In the ground position, an increase in the number of real technical actions is observed. Thus, at the beginning of the experiment this indicator was 30 attempts, at the end - 38. Due to this the total number of real attempts of technical actions increased. Also, there is an increase in the effectiveness of technical actions (beginning - 14 (47 %), end - 19 (50 %)) evaluated by judges as half a victory (beginning - 5, end - 8) and as a pure victory (beginning - 9, end - 11). Conclusions. It is established that under the influence of the offered models of technical and tactical preparation the use of combinations and counterattacks during a fight which allows to finish it earlier than the allotted time in sportsmen of the experimental group increased. The increase in the total number of real attempts to perform technical actions, as well as certain actions (throw with the emphasis of the lower leg in the thigh, picking up under one leg, turning with hands), their effectiveness was established. Also, there is a decrease in the number of throws from the knees in a fight and an increase in its effectiveness. Keywords: competitive activity, judo, training, weight categories, indicators, modeling, models.

Зміни самомотивації українських кікбоксерів 13-15 років в умовах пандемії коронавірусу та воєнного стану

Purpose: to assess the level of self-motivation of Ukrainian kickboxers aged 13-15 in the context of the coronavirus pandemic and martial law. Material and methods. Theoretical analysis of scientific and methodological literature, questionnaires, pedagogical research, methods of mathematical statistics. The theoretical analysis of scientific and methodological literature was carried out throughout the study. The next stage is the beginning of the pedagogical research, within which the control and experimental groups were selected. The selection of groups was realized on the basis of the results of an online survey conducted in May-June 2022 and covered 42 respondents (kickboxers aged 13-15 years old, qualified as 1st category and candidates for master of sports, representatives of the martial arts club «Athlete» (Kyiv), training program, age, qualifications of which correspond to the curriculum of sports schools in kickboxing). The survey was conducted online using a Google form according to the methodology of identifying the level of self-motivation of athletes to achieve high sports results. The questionnaire contained 14 statements. The reliability of the results and the determination of the homogeneity of the groups were carried out according to the Mann-Whitney criterion. Results: a thorough analysis of the scientific and methodological literature allowed us to state that the conditions in which sports in Ukraine found itself after the introduction of martial law prompted the search for new ways to overcome the motivational crisis among athletes in unfavorable social and social circumstances. The study showed that the level of self-motivation of skilled kickboxers was recorded mainly within the low and medium range. The results of the survey indicate that only 9,5 % of the surveyed kickboxers were able to maintain a high level of self-motivation in competitive activities. Despite the crisis conditions they are currently facing. Instead, 23,8 % of respondents are at a low level of self-motivation in competitive activity, which encourages an active search for ways to solve these problems. Conclusions. The analysis of special scientific and methodical literature revealed insufficient data and methodological developments aimed at increasing the level of self-motivation of kickboxers in preparation for competitions. Thus, the introduction of new scientific approaches to the formation of motivation and self-motivation for competitive activity in the training of kickboxers living under martial law is currently a very relevant area of research.

Effect of the identical training process on the functional state of high-level sprint swimmers of both genders

Purpose: to study the effect of an identical training process on the functional state of high-level sprint swimmers of both genders.
 Material and methods. The heart rate variability indices, central hemodynamic parameters and PWC170/kg measurements were compared between 86 male and 42 female swimmers with sports qualifications from first-class athlete to Master of Sports International Class, and separately, – between 38 males and 9 females (Masters of Sports and Masters of Sports International Class), 28 males and 16 females (Candidates for Masters of Sports), and 22 males and 17 females (first-class athletes).
 The results. In the general group (86 males vs. 42 females) only the greater value of PWC170/kg in males by 12.64 % (p<0.001) was revealed, without any differences in heart rate variability and central hemodynamics. Masters of Soprts and Masters of Sports International Class, as well as Candidates for Masters of Sports, didn't have gender differences in all indicators studied. In first-class athletes, there were no gender differences in heart rate variability and central hemodynamic parameters, except for PWC170/kg, which in males was greater by 11.27 % (p=0.036).
 Conclusions. A comparison of 86 male and 42 female swimmers with sports qualifications from first-class athlete to Master of Sports International Class, who differed by age and training experience, showed no significant differences in HRV and central hemodynamic parameters except for PWC170/kg, which was 12.64 % higher in males (p<0.001). There were no significant differences between all studied indices in 38 male and 9 female swimmers with sports qualifications Master of Sports and Master of Sports International Class, with no differences in age or training experience. Comparison of 28 male and 16 female swimmers with sports qualification Candidate for Master of Sports, not differing by age and training experience showed no significant differences in HRV and central hemodynamic parameters, except for PWC170/kg, which was greater in males by 11.27 % (p=0.034). In 22 male and 17 female swimmers with sports qualification first-class athlete, not differing by age (males have greater training experience) there were no differences between all studied indices.

Study of the psychomotor abilities of athletes in cyclic sports, martial arts and esports

Purpose: to conduct a comparative analysis of psychomotor abilities in athletes of cyclic sports (short track), martial arts (karate, taekwondo) and esports (CS:GO). Materials, participants and methods: The study involved athletes of percussion martial arts (n=10, age 18,9±0,12, candidates for master of sports), elite players of semi-professional CS:GO teams (n=10, age 19,2±0,50), short track speed skaters (n=10, age 19±0,09, masters of sports). The choice reaction time, the frequency of local movements (60-second tapping test), and the reaction time to a change in the size of the object (Size-test) were determined. Research results. Esports athletes have the best reaction time of choice and tapping test compared to other athletes. The wrestlers showed the best reaction to distinguishing the size of an object in the Size-Test. Skaters have high rates of complex reaction time and frequency of movements. The duration of the tapping test has a likely inverse relationship with the frequency of tapping. Conclusions. It was found that esports athletes have a significantly better choice reaction time (p<0,05) than martial arts athletes. The results of short track skaters do not have significant differences with martial arts and esports athletes (p>0.05). The results of the tapping test in terms of the total number of movements and the average number for 5 s in esports athletes tend to be higher compared to short track speed skaters and martial arts athletes. The fastest response time to a change in the size of an object in the Size-test was shown by martial arts athletes, the slowest by short-track skaters. This reflects the trend towards better results of this type of reaction in martial arts athletes compared to short track speed skaters and esports athletes.

Changes in the reactivity of the vertebrobasilar arteries when using glucose-electrolyte drink with antioxidant plant extracts during submaximal exercise test

The aim. To assess the effect of glucose-electrolyte composition with plant extracts having antioxidant activity on the hemodynamic parameters of vertebrobasilar system during the incrementally increasing submaximal exercise test.Materials and methods. The study included 12 athletes (6 candidates for master of sports and 6 masters of sports) aged 18–22, who have been engaged in orienteering for 10 years and more. Time of aerobic exercise – 2 hours a day, five days a week. The study subjects performed an incrementally increasing submaximal exercise test and also submaximal exercise test with the preventive intake of a glucose-electrolyte composition with plant extracts having antioxidant properties. To assess the hemodynamic parameters in all study subjects we used Doppler ultrasound of the cerebral vessels, evaluating vertebrobasilar system blood flow, exercise gas test in the modification of hypo- and hyperventilation, and also positional test.Results. A single intake of glucose-electrolyte drink under conditions of incrementally increasing exercise test contributed to the manifestation of a homeostatic effect in hemodynamic parameters of the vertebrobasilar arteries. It is evidenced by the approximation to the pre-exercise level of maximum systolic velocity and average blood velocity in the breath-holding test, of the diastolic blood velocity in the hyperventilation test, and of the pulsatility index in the torsion test, as compared to the isolated submaximal exercise test which caused the change in both velocity indicators and calculated indices during the functional tests.The article considers the main mechanisms underlying the change in arterial hemodynamic parameters caused by incrementally increasing load, as well as describes the proposed mechanisms arising from the combined effect of an incrementally increasing load and the intake of a glucose-electrolyte composition with plant extracts having antioxidant activity.Conclusion. It was shown that using glucose-electrolyte drink contributed to the restoration of hemodynamic parameters of the vertebrobasilar arteries after an incrementally increasing submaximal exercise test.

Heart rate variability in cross-country skiers with different level of maximum oxygen consumption

AIM: This research aimed to study heart rate variability (HRV) in cross-country skiers with different levels of maximal oxygen consumption (VO2max).
 MATERIALS AND METHODS: HRV analysis was carried out using the Ecosan-2007 (Medical Computer Systems, Russia) complex in 52 cross-country skiers from the Komi Republic team (candidates for master of sports and master of sports of Russia). The Oxycon Pro ergospirometric system (Erich Jaeger, Germany) was used to calculate VO2max. To identify the HRV patterns in individuals with different levels of VO2max, volunteers were divided into two groups: with VO2max up to 4400 ml/min (n=27) and over 4400 ml/min (n=25). The MannWhitney U-test was used to ascertain whether the differences between groups were statistically significant. A Spearman correlation test was used to analyze the relationship between the VO2max and HRV.
 RESULTS: Athletes with different levels of VO2max showed significant differences in several HRV indicators as follows: absolute values of LF and VLF waves, the relative value of HF waves, LF/HF, and IC indices. Correlation analysis indicated the presence of a significant negative correlation between the absolute values of VO2max and MxDMn, MxRMn, LF/HF, IC, power of LF, and LF%. VLF waves. Furthermore, a positive correlation was observed between VO2max and HF%. The relative values of the VO2max/kg showed a significant negative correlation with MxRMn, TP, LF, VLF, LF/HF, and IC; and positive with HF%.
 CONCLUSION: In cross-country skiers, a significant correlation was identified between VO2max and HRV parameters. Compared to Athletes with lower VO2max, those with higher VO2max had a more efficient mode of heart rate regulation.

Day's periodicity of vegetative functions for swimmers taking into account the phases of days-long biorhythms

In this work we studied day's periodicity of indexes of cardiovascular and respiratory systems for swimmers depending on the phases of physical multi-day biorhythms at the beginning of the competitive stage of preparation. In a sports camp 5 girls and 11 young men age 15-17 masters of sports and candidates for master of sports at swimming, took part at scientific research. The presence of two peaks of sizes of indexes of vegetative functions which are observed after the first and third training is educed. According to the level of functional readiness, the subjects were divided into 3 groups: with a good functional state, with its deterioration as a result of an acute respiratory disease or overwork, and with a satisfactory state. An assessment of the functional state of each athlete was made at the beginning and end of the training camp. Health status, sleep, well-being assessment, etc. about swimmers was taken into account in the analysis of the material. During the exchange of rest, the indicators of vegetative functions most fully reflect the state of the athlete on the day of the examination.

Indicators of implementation standards of the candidate for master of sport and the first rank by athletes in game sports of ivano-frankivsk region during 2018-2021

One of the results of the work of subjects of physical culture and sport in the athletes’ preparation is the criterion of evaluation for implementation of certain ranks requirements. According to the section of sports ranks at three levels: mass ranks, reserve, sports ranks, it is necessary to plan the analysis of the state of work on them. This can be done within individual regions. Purpose: to establish indicators of implementation standards of the candidate for Master of Sport and the first rank by athletes in game sports in the Ivano- Frankivsk region during 2018-2021. Methods: theoretical analysis and generalization of data of scientific and methodical literature, analysis of documentary materials, methods of mathematical statistics. The content of the orders "On the assignment of sports ranks" of the Sport Department of the Ivano-Frankivsk Regional State Administration for the period 2018-2021 (in total 31 documents) was studied. Results. Reserve sports are mostly characterized by sport ranks of the candidate for Master of Sport and the first rank. During 2018−2021, there is a significant variability in the number of athletes in game sports who met the requirements of sports ranks of the candidate for Master of Sport and the first rank. Higher values are inherent for 2018 and 2020 (126 and 169 people) and much less for 2019 and 2021 (43 and 59 people). The shares of representatives of game sports had significant differences over the years and ranged from 27.92 to 52.65% of the total number of those who met the requirements of sport ranks of the candidate for Master of Sport and the first rank. In the structure of game sports athletes who met the requirements of the sport ranks of the candidate for Master of Sport and the first rank during 2018-2021, the largest share is occupied by football (44%). The second position is occupied by rugby representatives (17%). Then a group of sports with approximately the same contribution of 9-10% (basketball, table tennis, volleyball, futsal). Conclusions. According to the indicators of the requirements for the awarding of sport ranks of the candidate for Master of Sport and the first rank in Ivano-Frankivsk region revealed the existence of a prominent leader among the sports – football and a certain core, which includes five other sports (basketball, table tennis, volleyball, futsal, rugby).

Взаимосвязи гормонального статуса и показателей красной крови с кардиореспираторной выносливостью у спортсменов и нетренированных юношей

The aim of this paper was to study red blood cell parameters and levels of thyroid-stimulating hormone (TSH), free thyroxine (FT4) and cortisol, as well as their correlations in young male athletes and non-athletes, depending on their cardiorespiratory endurance. Materials and methods. The study involved 18 athletes (weightlifting, kickboxing) with the ranks ranging from First-Class Sportsman to Candidate for Master of Sport and 38 non-athletes. Hormone concentrations in the blood (cortisol, TSH, FT4) and blood parameters (haemoglobin, red blood cell count (RBC), their mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) and haematocrit (НСТ)) were determined. The subjects’ physical endurance was assessed by calculating the cardiorespiratory index (heart rate divided by the respiratory rate). Results. In young men not involved in sports, no statistically significant differences between red blood cell parameters and hormonal status depending on the cardiorespiratory index were observed. At the same time, athletes with low exercise tolerance had statistically significantly lower MCV, MCHC, FT4, and TSH as well as elevated cortisol levels compared to endurance athletes. In young male non-athletes, we established an inverse correlation of TSH with RBC (r = –0.27) and HCT (r = –0.31) as well as of FT4 with RBC (r = –0.35), HCT (r = –0.28) and cardiorespiratory index at rest (r = 0.29). In athletes, cortisol correlated with exercise tolerance (r = 0.74), while FT4 correlated with cardiorespiratory index after exercise (r = 0.69). Thus, a decrease in thyroxine and an increase in cortisol blood levels in athletes correlate with lower cardiorespiratory endurance and exercise tolerance, while in non-athletes, with the activation of the erythropoietic function.

Secular Trend of Body Dimensions in Highly Qualified Wrestlers

The purpose of the paper was to study the physique of highly qualified martial art athletes engaged in different types of wrestling, and to perform a retrospective analysis of the morphological characteristics of wrestlers examined since the early 1920s. The materials of the anthropometric survey of 48 athletes engaged in different types of wrestling with qualification from the candidate for master of sports and above were used for this purpose and compared to the "control group" of young men (N = 97) who were not engaged in sports (similar to the group of athletes by age, ethnicity and percentage of individuals with different weight categories). A set of morphological traits was established that contributed to the successful achievements in sports. When comparing the physique of modern athletes with that of the wrestlers surveyed in the early and mid-20th century (the 1920s and 1960s), it has been shown that the secular trend towards increase in height typical for modern population, was expressed in athletes to a much lesser extent. Striking similarities were revealed for absolute and relative dimensions characterizing the skeletal body proportions of the wrestlers, which pointed to the secular stability of this sports morphotype. The obtained results can be used as additional morphological criteria for sports selection, professional orientation and prediction of competitive success.

Эпохальный ретроспективный анализ показателей телосложения у спортсменов-единоборцев высокой квалификации

Introduction. The purpose of the paper was to study the physique of highly qualified martial art athletes engaged in different types of wrestling, and to perform a retrospective analysis of the morphological fea-tures of wrestlers examined since the early 1920s. Materials and methods. Anthropometric data of 48 male athletes who were engaged in martial arts (different types of wrestling) for many years and reached high qualifications (from a candidate for master of sports and above) were used in this study. Athletes were 18-31 years old (mean age – 20.62±0.43), almost all of Russian ethnicity, permanent residents of Moscow. For comparative analysis, the materials of the anthro-pometric survey of young men – students of different Moscow universities were taken (N = 97). The stu-dents were not involved in sports, were of the same age (20.19±0.29), of Russian ethnicity and represented with different weight categories. They were used as a "control group". Results. On the materials of the anthropometric survey of athletes engaged in different types of wrestling, in comparison with the so-called "control group", a set of morphological features was established contrib-uting to the successful achievement in sports. When comparing the physique of modern athletes and wres-tlers surveyed in the early and middle of the last century (1920s and 1960s), it is shown that the trend of the secular increase in height typical for modern population, is expressed in athletes to a much lesser extent. Striking similarities are revealed for absolute and relative dimensions characterizing the skeletal body pro-portions of the wrestlers, which indicates the secular stability of this sports morphotype. Conclusion. The obtained results demonstrate the patterns of formation of morphological features and secular stability of the morphotype of highly qualified athletes involved in different types of wrestling. Re-vealed complex of somatic features can be used as additional morphological criteria for sports selection, professional orientation and prediction of competitive success.

Состояние кардиореспираторной системы биатлонистов и лыжников-гонщиков Республики Коми при велоэргометрическом тестировании

The purpose of this paper was to compare the physiological parameters of the cardiorespiratory system at rest and during the bicycle ergometer test to exhaustion in biathletes and cross-country skiers to identify the difference in the aerobic performance of athletes of two closely related winter sports. Materials and methods: 18 biathletes and 28 male cross-country skiers aged 17–21 years, all with the rank of the Candidate for Master of Sport, were examined. Bicycle ergometer testing to exhaustion was used (Oxycon Pro, Germany), cardiorespiratory parameters were analysed, maximal oxygen consumption (VO2 max) was determined, and the physiological cost of a unit of work was calculated. Results. At rest, a statistically significantly higher level of fitness was revealed in crosscountry skiers compared with biathletes according to such haemodynamic parameters as systolic blood pressure, pulse pressure, and double product. At maximal load, an increased degree of fitness was found in cross-country skiers in terms of power and duration of bicycle ergometer exercise, cardiac and pulse cost per unit of work, as well as gross and specific VO2 max. The body of cross-country skiers under the test to exhaustion (according to oxygen pulse value) functions more efficiently than the body of biathletes. Thus, higher level of fitness among cross-country skiers of the Komi Republic is manifested in the economization of cardiorespiratory functions both at rest and at maximal ergometric loads, as well as in the value of specific physiological cost per unit of work. Increased functionality (or reserves) of cross-country skiers is indicated by such parameters as systolic blood pressure, pulse pressure, double product, respiratory minute volume, oxygen consumption, and energy expenditure. It can be assumed that the aerobic performance of biathletes is lower than that of cross-country skiers as the former receive less training in cross-country skiing.

Model characteristics of competition performance in terms of athletes’ functional fit-ness

Introduction. Nowadays, the theory of sports does not contain clear criteria for assessing sports fitness, which would reflect the model characteristics of competition performance. The article presents the research results on the functional state of athletes with different training process specifics as model characteristics of competition performance. The aim of the research is to identify and describe the model characteristics of competition performance as the main criterion for evaluating sports training in the theory of sports. Materials and Methods. Energy component of athletes’ functional fitness was studied in 80 qualified athletes (Candidates for Master of Sports, Masters of Sports, International Masters of Sports), specializing in running short, medium and long distances during the period of training for competitions. The study of the energy component was conducted using the inventory developed by B. F. Vashlyaev et al. (‘A method for evaluating physical performance based on minute volume of breathing dynamics ratio to increasing load power’). This method allows to identify which source of energy is used by the athlete while taking a cycle ergometer testing. Results. The authors identified the model characteristics of functional fitness in athletes with different training specifics, based on the energy component. The study provides physiological grounding from the point of view of appropriate interaction of energy supply systems. The key regulatory mechanisms associated with the metabolic reactions activation of adenosine triphosphate molecules production are described. Conclusions. Model characteristics of athletes' competition performance, obtained in this research, can be used by coaches in order to manage sports training effectively. Moreover, the identified model characteristics can be used as the main criteria for evaluating sports training in sports theory.

An analysis of effective adaptation, fitness variability, normal limits, stable and premorbid health states, overtraining and overwork is proposed.

Оцінка рівня функціонального стану і протікання специфічного біологічного циклу велосипедисток та спортсменок вільної боротьби 15-16 років

Purpose: to determine the functioning of the cardiovascular and reproductive system of cyclists and wrestlers 15-16 years under the influence of specific physical activity. Material and methods. 14 athletes took part in the research, 7 of them were freestyle wrestling (3 – I category, 4 – candidates for master of sports) and 7 – Mountain Bike (MTO) races (4 – I category, 3 – candidates for master of sports). Research methods: theoretical analysis and generalization of scientific and methodological literature, pedagogical and biomedical research methods, methods of mathematical statistics. Results: the analysis of educational programs (freestyle wrestling, cycling-MTV) of the age group of 15-16 years showed that in these kinds of sports a different mode of educational and training work during the annual cycle. So, for freestyle wrestling athletes in the age group 15-16 years old, special physical training is planned for 100 hours, psychological training for 20 hours, competitive training for 42 hours, for 70 hours – rehabilitation means for 6 hours – medical control, while female cyclists – MTB is 12 hours more than general physical training, 144 hours more – technical and tactical. After the training year, the analysis of the trainers' plans showed that in freestyle wrestling, the percentage of general physical training has changed and amounted to 16 %, special physical – 24 %, technical and tactical – 33 %, psychological – 4 %, while in cycling general physical training – 19 %, special physical – 25 %, technical and tactical – 34 %, psychological – 6 %. Special and technical-tactical work by 1 % and psychological work by 2 % more were performed by cyclists relative to wrestlers. Comparison of the indicators of the cardiovascular system of female athletes showed a statistical difference in systolic blood pressure (t=3,60; t=8,92; p<0,001), in diastolic blood pressure (t=3,56; t=6,00, p<0,001), in the aerobic metabolic capacity (t=5,08; t=7,07; p<0,001), in the anaerobic metabolic capacity (t=12,20; t=8,14; p<0,001). According to a survey of female athletes, it was determined that in September 2019, 33 % of athletes 15-16 years old had irregular menstruation and 67% – regular, in December 2019 4 3% – irregular and 57 % – regular, in May 2020 50% – irregular and 50 % – regular, in September 2020 57 % – irregular and 43 % – regular menstruation. Conclusions. The analysis of curricula for the chosen sport and training plans of coaches by types of training showed that the specificity of the training process is the specificity of the discipline in which relatively independent types are clearly visible, and the distribution of training and competitive physical loads is interconnected with the stage of training. Comparison of the indicators of the cardiovascular system of female athletes 15-16 years old showed that higher performance in cyclists as a result of training (physiologically athletic heart. At the same time, among wrestlers it was recognized as more optimal indicators of the heart muscle for further improvement of sportsmanship. The negative dynamics of the ovarian cycle at the age of 15-16 years was determined, which amounted to 21 % of irregular menstruation. Keywords: freestyle wrestling, cycling-MTB, specific biological cycle, cardiovascular system.

REFLECTION AS A PROFESSIONAL-IMPORTANT QUALITY OF AN ATHLETE: PROBLEM STATEMENT AND RESULTS

Abstract. The relevance of the study lies in the fact that recently it is possible to notice a trend in the popularity of sports, an increase in the requirements for athletes (high-quality performance of sports activities, functions, the ability to develop potential capabilities), which determine success in sports and competitiveness. The article discusses various factors that affect the effectiveness and success of an athlete: individual psychological characteristics of a personality, his professionally important qualities, motivational sphere, mental states, volitional efforts. Among the listed factors, reflection is of no small importance as one of the professionally important qualities of an athlete. The theoretical analysis of the psychological and pedagogical literature made it possible to conclude that reflection is an activity that must be trained, master its features and use in one's sports activity. It acts as a system-forming characteristic of the cognitive activity of an individual, which allows one to build new patterns of one's behavior, to develop certain knowledge. The study of the problems of reflection in sports has both theoretical and practical significance in sports psychology and pedagogy. The systematic manifestation of reflection by an athlete contributes to the development of reflexivity as a quality. As a result, his recognition of the planned actions on the playing field will allow him to plan his actions in this situation. The article presents a meaningful characteristic of different types and forms of reflection. The aim of the research is to determine the level and types of reflexivity in athletes. The study involved 1545 athletes - students of sports schools of the Olympic reserve, children and youth schools, national teams of the Sverdlovsk region, Masters of Sports, Candidates for Master of Sports, athletes with I, II, III categories at the age of 14-18 years.
