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).

Extensive Reading on Postgraduate Students' Perceptions and Its Effects on Reading Comprehension

Several studies have shown the effectiveness of extensive reading (ER) in English as a second language (ESL) and English as a foreign language (EFL) classrooms. This study aimed to explore students' perceptions of ER and its benefits on reading comprehension. Extensive reading is considered to be a useful reading technique to arouse students' reading abilities. Data were collected from 36 participants who are master's candidates at a university in Southern Vietnam through a 3-Likert scale questionnaire and a semi-interview on study issues. The findings of the study claim that students applied ER to their reading processes through free reading, free topics, and non-pressure on reading tasks. Students believe that ER activities help to improve reading competence and unconsciously build up a reading habit for readers. From the results of the study, ER proves its advantages by what students gained, such as the ability to comprehend reading passages and to make inferences or predictions. The researcher suggests further studies should focus on factors that affect ER processes and conduct experimental research to evaluate ER advantages.

Time Characteristics of Technical Readiness of Female Triple Jumpers of High Qualification

Background. The relentless growth of sports results and the lack of comparative analysis of a set of indicators of technical readiness of female triple jumpers of various qualifications indicates the viability of research in this regard.
 The study purpose was to specify the time characteristics of technical readiness of female triple jumpers of high qualification.
 Materials and methods. We used the following research methods: theoretical analysis and generalization of data from scientific and methodological literature, pedagogical observation, instrumental methods (video recording) and methods of mathematical statistics. The study was conducted on the basis of investigating the time characteristics of the technical readiness of skilled triple jumpers. The pedagogical experiment took place during the competitions of the Cup of Ukraine and the Championship of Ukraine in Athletics. The study involved 9 female triple jumpers (average age 25.3 ± 5.1), including two masters of sports of international class of Ukraine, four masters of sports of Ukraine, and three candidates for masters of sports of Ukraine. 
 Results. In the course of the study, we found that the indicators of the duration of the reference periods of the last 6 steps of the run in the triple jump by female jumpers of high qualification are characterized by a low level of variability. In terms of flight duration, the highest variability was observed in the 3rd, next to last and last steps of the run. According to the results of the study of rhythmic-tempo characteristics of a triple jump of high qualification, it was established that the highest indicators of the pace of the running step are at the last step of the run and reach 4.67 ± 0,03 st./s. The correlation between such time characteristics as the duration of the flight period of the next to last run step (r = -0.85), the rate of the next to last (r = 0.60) and last step (r = 0.78), and the rate of intensity (r = 0.76) with a sports result. In the triple jump by female jumpers of high qualification, indicators of the duration of the phases of “jump”, “step”, “jump”, their total duration and the average speed of the jumping phases are characterized by a low level of variability. The duration of the “hop” is 0.66 ± 0.06 s. The longest phase is the “jump” phase (0.78 ± 0.06 s), and the shortest is the “step” phase (0.51 ± 0.04 s).
 Conclusions. It was established that due to the reduction of the duration of flight periods in the last steps of the take-off, there is an increase in the take-off speed of high-skilled jumpers. The variability of the contrast between the growth rate of 31.90% and the rate of mobilization of 35.12% indicates that high-skilled jumpers use different options to combine takeoff and repulsion. Analysis of the rhythmic structure of the triple jump technique shows that all jumps are dominated by the phase of “jump” (40.05%), and the shortest is the phase of “step” (26.30%). It was found that the following time characteristics: the duration of the flight period of the next to last run step (r = -0.85), the pace of the next to last step (r = 0.60), the pace of the last step (r = 0.78), and the pace intensity (r = 0.76) have a statistically significant relationship with sports results (p < 0.05).

Generation of a chromosome-level genome assembly for Pacific halibut (Hippoglossus stenolepis) and characterization of its sex-determining genomic region.

The Pacific halibut (Hippoglossus stenolepis) is a key species in the North Pacific Ocean and Bering Sea ecosystems, where it also supports important fisheries. However, the lack of genomic resources limits our understanding of evolutionary, environmental and anthropogenic forces affecting key life history characteristics of Pacific halibut and prevents the application of genomic tools in fisheries management and conservation efforts. In the present study, we report on the first generation of a high‐quality chromosome‐level assembly of the Pacific halibut genome, with an estimated size of 602 Mb, 24 chromosome‐length scaffolds that contain 99.8% of the assembly and a N50 scaffold length of 27.3 Mb. In the first application of this important resource, we conducted genome‐wide analyses of sex‐specific genetic variation by pool sequencing and characterized a potential sex‐determining region in chromosome 9 with a high density of female‐specific SNPs. Within this region, we identified the bmpr1ba gene as a potential candidate for master sex‐determining (MSD) gene. bmpr1ba is a member of the TGF‐β family that in teleosts has provided the largest number of MSD genes, including a paralogue of this gene in Atlantic herring. The genome assembly constitutes an essential resource for future studies on Pacific halibut population structure and dynamics, evolutionary history and responses to environmental and anthropogenic influences. Furthermore, the genomic location of the sex‐determining region in Pacific halibut has been identified and a putative candidate MSD gene has been proposed, providing further support for the rapid evolution of sex‐determining mechanisms in teleost fish.

Determining the optimal areas of effort in terms of force and force-velocity based on the functional state of the neuromuscular system in the training of elite female judokas.

BackgroundThe evaluation of the functional state of the neuromuscular system (NMS) in elite female judokas according to the muscular activity indices is influenced by the force (F) and force-velocity (F-V) efforts. The implementation of the individual correction plan in the elite female judokas’ process of instruction and training must be based on the accurate determination of the force and force-velocity effort areas throughout the training and competitive periods.MethodsThe research involved 44 elite female judokas, divided in to two experimental groups (A, C) and two control groups (B, D). To diagnose the NMS, 21 elite female judokas were evaluated, belonging to different classification categories, divided into three groups: group I–category I (Cat. I), group II–candidates for Masters of Sports (CMS) and group III—Masters of Sports (MS).The evaluation of NMS was performed at the end of each two-week cycle, using 3 tests: Tmax—time to reach the maximum muscle contraction, (msec); Fy –examination of elasticity indices in different muscles, (Hz); J–explosive muscular strength, (kg/s). Measurements were made for six muscle groups and 9 indices of fitness tests: 5 force tests (F) and 4 force-velocity tests (F-V). The research was carried out during 24 cycles, each one lasting two weeks: 12 training cycles and 12 competitive ones. Each cycle lasted two weeks. During the research, the model plan of training for F and F-V was used, determining the optimal areas of F and F-V training efforts in the preparation and competitive periods. In the experimental groups (A and C), according to the data of judokas’ NMS functional state evaluation, the individual correction of the F and F-V efforts was performed every two weeks. As for the control groups (B, D), traditional methods of training were used.ResultsThe NMS evaluation of the female judokas was made every two weeks and the level of correlation of Tmax, Fy and J indices was determined. The value of the Fy index at F effort is 32% in group I, 30% - in group II, 27% - in group III, 28–30% at the effort of F-V. The total number of corrections in group A: 79 negative corrections and 59 positive corrections, while in group C: 65 negative corrections and 89 positive ones. Within the F-V effort, the number of effort corrections in group A was: 68 negative corrections and 92 positive; in group C - 81 positive and 78 negative corrections. The female judokas’ results in the final stage of EG–A were significantly improved in F indices by 52.15%, F-V by 6.22% and 6.18%. In the EG–C, the F increased considerably by 7.52%, F-V by 5.67% and 7.20%. These results characterize the level of physical training.ConclusionThe functional state of the NMS in elite judokas, determined according to the temporal indices of reaching the maximal muscular contraction, the muscle explosive strength and the muscles elasticity, is subjected to dynamics under the influence of force effort and force-velocity effort.

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.

Prediction and Management of the Quality of Classified Student Training Based on an Improved Neural Network

Personalized teaching and classified training promote each student to develop in the most suitable direction. The studies on classified student training (CST) mainly target the objects of CST, which refers to the classified training of underachievers and achievers, or the classified training of different groups of high-quality talents like doctoral students and master candidates. However, there are few research results on the implementation or quality forecast of CST. To fill up the gap, this paper explores the prediction and management of the CST quality based on an improved neural network. Firstly, a cognitive diagnosis model for CST was established to realize targeted group learning. Thereafter, an evaluation index system (EIS) was constructed for student learning quality. Next, a prediction model was built based on improved backpropagation neural network (BPNN), and the particle swarm optimization (PSO) was called to optimize the weights and thresholds of the neural network. The effectiveness of our model was proved through experiments. The relevant findings provide impetus to the timely update of CST.

Prerequisites for motivating achievements in rhythmic gymnastics

The purpose of the study is to identify the prerequisites for the motivation of achievement in rhythmic gymnastics. To achieve the goal, methods of psychological diagnostics were used: questionnaires "Motivation to success" and "Motivation to avoid failures" by T. Ehlers, the questionnaire "Rational-experienced" by Epstein, diagnostics of emotional intelligence by N. Hall. The sample of subjects consisted of 40 athletes aged 15-21, masters of sports and candidates for masters of sports in rhythmic gymnastics. It was revealed that in the course of the study, differences in the relationships between personal resources of athletes of different qualifications were revealed. The candidates for the master of sports revealed a direct relationship between the motivation for success and emotional awareness, and the masters of sports added the management of their emotions and the use of intuition, which suggests that there is a relationship between the motivation of achievements and the expression of personal resources in gymnasts of different qualifications.

CONTROL OF SPECIAL PHYSICAL TRAINING FOR QUALIFIED FEMALE VOLLEYBALL PLAYERS OF DIFFERENT GAME ROLES

Modern competitive activity in volleyball makes high demands on the fitness of athletes, where the leading role belongs to technical-tactical and special physical. Control and interconnection of technical-tactical and special physical fitness will ensure to provide the effectiveness of the training system for qualified female volleyball players. The aim of the research is to analyze the manifestation of special physical qualities of qualified female volleyball players of various playing roles and their interconnection with the effectiveness of technical and tactical actions. The study has involved 48 qualified volleyball players (including 6 masters of sports of Ukraine, 20 candidates for masters of sports of Ukraine, 22 female athletes of the first sports category). Close correlations were obtained between the absolute and relative indicators of the use of technical and tactical actions with the special preparedness of qualified female volleyball players: for binders - the results of the test of flexion and extension of the arms in the lying position closely correlates (r = 0.78 and 0.84) with the efficiency of the serve; for players of the second temp of attack rate - the results of the shuttle run test (9-3-3-9 m) closely correlate (from r = 0.77 to 0.88) with the serve; for the players of the first temp of attack rate, the performance of the test of raising the trunk in the prone position closely correlates (r = 0.70 and 0.78) with the effectiveness of the ball pass; libero - the highest correlational connections (r = 0.92 and 0.96) are observed when performing the shuttle run test (9-3-3-9 m) and the effectiveness of protective actions. On the basis of the obtained significant correlation coefficients, linear regression models of the relationship between the effectiveness of the application of technical and tactical actions and the results of pedagogical testing were constructed.

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.

Selection of Playing Style in Table Tennis Depending on the Complex of Psychophysiological Indices

The Research Purpose is typological predisposition and psychomotor indices studying directed on the table tennis playing style formation. The Methodology of the Research. 114 male tennis players: 5 Masters of Sports of International Class, 39 Masters of Sports, 38 Candidates for Masters, 32 athletes of the first category have been examined. Typological peculiarities, in particular, strength of nervous system relative to excitation; mobility-inertness of excitation and inhibition, external and internal balance have been studied. The Research Results. An offensive strategy is associated with the following typological features: the nervous system of high and average strength (amid the common to all tennis players’ weakness of the nervous system) as a reflection of their predominance of excitation in the external balance. Defensive strategy players are characterized by a high resistance to monotony, a greater expression of the nervous system weakness, and a predominance of inhibition according to internal balance. Mixed strategy players are distinguished by a relatively higher (than in defenders) strength of the nervous system, balance of excitation and inhibition processes, and greater mobility of excitation and inhibition processes. The offensive strategy players are characterized by higher motion pace and auto pace as compared to those of mixed and especially defensive strategy play. Defensive strategy players` time of simple and complex visual-motor reaction is significantly higher as compared to those who prefer the offensive strategy. Defensive and mixed strategy players have got the deferred reactions tend to dominate during the response to moving object, whereas offensive strategy players – premature responses are observed. In order to adequately perceive the current situation and have more time to decide on the proper response action, they have to move further way from the tennis table than the offensive strategy players. Conclusions: Study has conducted for examination of typological predispositions and psychomotor indices that condition directed formation of table tennis playing style. It is important direction of training.

Model Morpho-Functional Characteristics of Qualified Volleyball Players

The significant influence of somatic and functional characteristics on the sports result makes it advisable to justify the model indices of qualified players who are considered to be ideal models in their sport. The purpose of the study was to determine the model morpho-functional characteristics of qualified male and female volleyball play- ers of the Ukrainian Super League. The study involved 12 female and 13 male volleyball players that were qualified as masters of sport, candidates for masters of sports. Morpho-functional diagnostics aimed at determining the body composition of players (fat, muscle, bone components, total water content). According to the results of the anthropometric measurement and morpho-functional diagnostics of qualified volleyball players, we came up with 18 indicators that characterized the constitution and the body composition of athletes’ weight. The analysis of the obtained data showed a slight skewness in the distribution of fat and muscle components in the athletes’ legs and arms, which was explained by the nature of the volleyball game. The significant potential of Ukrainian volleyball players, the availability of the reserved functional resources was evidenced by their anthropometric indicators, the content of fat and muscle components in the body, which were not significantly different from the similar indicators of the players of the leading national teams and professional volleyball clubs. The results of the research can serve as a guide and facilitate the selection, training and specialization of gifted Ukrainian youth.

Moving to a Virtual Literacy Practicum: Challenges and Solutions

When the university took the unprecedented move to virtual teaching at the start of the COVID-19 pandemic in March 2020, my challenge, as a teacher educator, was to plan a virtual literacy practicum for master candidates. All aspects of curriculum design were considered, from establishing relationships with schools, parents, and students, considering technology platforms, appropriate technology applications, to considering everyone’s emotional state. In this article, I share the many challenging aspects and the solutions that lead to successful experiences for all participants.
