Access to test selection in children’s athletics – Prediction of reaching maximum speed level and result in sprint based on dynamickinematic parameters, speed-strength abilities and morphological characteristics

Running speed in the form of sprinting is one of the most important abilities that can significantly define performance success in many sports. From the perspective of genetically inherited motor functions, running speed can be classified as a primary phylogenetic human movement, manifested in the form of a “threesegment model” consisting of speed, power, and coordination. By comprehensively analyzing the general and partial predictive contributions of dynamic-kinematic parameters of running, speed-power abilities, and morphological characteristics, on a sample of 80 boys aged 10-12 years, it can be concluded that regardless of the choice of criteria, achieved maximal speeds (KVMAX) or results in children’s athletic sprint over 50 meters (KT50m), the same or related predictor variables contributed to the explanation. The variable running time for 20m from a flying start (KTLS20m) has the greatest predictive contribution (β=0.83, p<0.001) to explaining both criteria, which may indicate the importance of conducting this test in the identification and selection for athletic sprint. Additionally, the selection of tests to assess speed-power abilities is extremely important for the identification and selection for athletic sprint. It can be concluded that tests of horizontal and vertical jumps are significant for identification, as well as tests for assessing neuro-muscular excitation. Tests for assessing continuous horizontal jump are also important, although there is an impression that, in boys aged 10-12 years, coordinatively simpler tests should be used. In the analysis of morphological characteristics, variables that significantly contributed to the explanation of criteria at a partial level were body height, back skinfold, and ankle diameter, indicating that in the identification of talented individuals, it should be considered that elite sprinters are characterized by light bones, optimal muscle mass, and low levels of subcutaneous fat tissue.

Development of strength abilities of high school students by means of health fitness

The article highlights the problem of developing strength abilities in high school students by means of fitness in a physical culture and health center. It is emphasized that one of the most effective means of maintaining the proper psycho-emotional and physical condition of schoolchildren in the conditions of war in Ukraine is regular physical activity. In this regard, the improvement of the entire system of physical education, in particular, of high school students, is one of the directions for improving their health, increasing motivation for physical education both in educational institutions and in physical culture and health facilities. Іt is noted that strength fitness classes are popular among high school students, which includes a large number of various training programs that differ in their structure, content, and implementation methods. Thus, the purpose of the study is to highlight the theoretical and methodological features of strength fitness classes for high school students in a physical education and health center. Attention is focused on the fact that the method of using strength exercises in health fitness is significantly different from that in strength and speed-strength sports, since the main task of the classes is not the maximum development of strength qualities, but the improvement of the physical condition of the participants. The basic principles of strength training include the correct selection of strength exercises, repetitions, sets (approaches), the pace of exercises and the amount of weight, rest intervals. The authors defined the means and methods of developing strength abilities, the requirements for planning a fitness program for young men aged 15-17, outlined the criteria for the effectiveness of strength fitness classes, and developed methodical recommendations. Therefore, the technology of developing strength abilities includes: analysis of age, sex, and individual characteristics of the development of strength and speed-strength abilities; implementation of the principles of physical education in the process of strength development; methods of strength development (means and methods of strength development; load and rest; programming, forms of organization of classes); pedagogical control over the development of strength abilities. Means of recovery of working capacity should also be used: massage, vitaminization, rational nutrition.

Features of the development of speed skills in football players

This article examines the issues of speed training, training speed in football players aimed at increasing running speed and "transferring" this speed to running with the ball. This process of "transferring" speed abilities is more effective when an athlete in normal running emphasizes the frequency of movements, but not the length of running steps, that is, he overcomes training segments with slightly shortened steps, which in their rhythmic structure are similar to steps in running with m' cell. Speed training falls, in fact, on the pubertal phase of the body development of young athletes, when puberty is accompanied by a rapid increase in muscle mass, glycogen reserves, and an increase in the level of secretion of adrenaline and gonadal hormones. At this time, optimal biological prerequisites are created for the development of anaerobic capabilities, maximal strength, power endurance, and speed-power qualities. The volume of loads should increase at the fastest pace in the development of strength endurance, which reaches its maximum values by the end of the stage. Gradually, exercises with maximum efforts, performed in overcoming, yielding and isokinetic modes, are included in the training.
 Speed abilities are very difficult to develop. The possibility of speed increase in locomotor cyclic acts is very limited. In the process of sports training, an increase in the speed of movements is achieved both by influencing the actual speed abilities, and in another way - through the development of strength and speed-strength abilities, speed endurance, improvement of the technique of movements, etc., i.e. improvement of those factors that significantly depend on the manifestation of certain qualities of speed. Numerous studies have shown that the aforementioned types of speed abilities are specific. Direct positive transfer of speed takes place only in movements that have similar semantic and programming aspects, as well as motor composition. The specific features of speed abilities are noted, so they require the use of appropriate training tools and methods for each of their varieties.

Comparative Analysis of the Efforts of Highly Qualified Elite Armwrestlers with Different Strength Abilities

Study purpose. Determination of the peculiarities of the manifestation of strength in competitive exercises of highly qualified armwrestlers with different strength abilities. Materials and methods. The study involved the 4 best armwrestlers in the world weighing from 80 to 100 kg (m = 87.50 ± 2.47 kg) in 2017–2020. Four power test exercises have been identified that ensure the performance of a competitive action in armwrestling: flexion of the fingers, stretch with a hammer, hook and bending the hand. Strength indicators in all test exercises were measured with an FL1K 0.5N, 1000N electric strain gauge dynamometer, Kern & Sohn GmbH (China), fixed on the armwrestling table using an author’s block device. Results. The results of the correlation analysis of the relationships between the studied indicators confirm the presence of a difference in the direction and strength of the relationships between the strength and time characteristics of the efforts of athletes with different strength and speed-strength abilities. Thus, out of 36 correlation indicators, the data of armwrestlers 1 and 2 have 11 modules with very high connection strength (r = 0.926–0.999), of which 7 modules are with time and 4 modules are with force characteristics of efforts. Athletes 3 and 4 also have 3 modules with very strong connections (r = 0.916–0.948) and 8 modules with strong connections (r = 0.739–0.886), of which 7 modules are with strength indicators and 4 modules are related to time characteristics. But the other correlation indicators have very weak (r < 0.29) and weak (r = 0.3–0.5) levels of relationships. Conclusions. Analysis of the time and force characteristics of the manifestation of force in the process of achieving boundary resistance allows us to clearly establish the genetically determined speed and strength abilities of the explosive, fast and slow force of armwrestlers.

Development of speed-strength abilities of 11-12 year old rugby players using a set of special exercises

Purpose: to select and experimentally test the effectiveness of complexes of special exercises for the development of speed-strength abilities of rugby players at the stage of preliminary basic training. Material of the study: the study involved 24 young athletes aged 11–12 years who trained at the stage of preliminary basic training. Research methods: indicators of speed-strength abilities of 11-12 year old rugby players were determined using the following tests: 30 m run from a high start, standing long jump, triple jump, 30 m run with a ball, shuttle run (3x10 m), passing the ball in pairs. Results: a different degree of correlation was established between the indicators of test exercises that were used to determine the speed-strength abilities of 11-12-year-old rugby players: between the results of tests of running 30 meters from a high start, standing long jump, a triple jump from a place and running to 30 meters with the ball, and between the 30 meters run with the ball and the shuttle run 3 x 10 meters - a significant relationship (r=0,712-0,817). Between the results of standing long jump, a shuttle run of 3 to 10 meters and the number of ball passes on the spot in pairs, there is a low degree of manifestation (r = 0,309-0,455). Between the indicators of other test exercises that were used in our study, a moderately pronounced relationship was established (r=0,499-0,674). Conclusions: the effectiveness of the use of complexes of special exercises for the development of speed-strength abilities of rugby players at the stage of preliminary basic training has been proven. Significant differences between the test results of the control and experimental groups were established: 30 m run, standing long jump, triple jump, 30 m run with the ball, passing the ball in pairs.

THE IMPACT OF HEALTH-IMPROVING TECHNOLOGY ON ELEMENTARY SCHOOL CHILDREN

The well-being of a child reflects their ability to withstand challenging and harmful factors, and their stability is determined by achieving a balance in key physiological functions during their development. According to the Ministry of Health of Ukraine, approximately 90 percent of children exhibit various health deviations, with over 59 percent experiencing poor physical condition. The health of children can be viewed as a dynamic and functional state, serving as an indicator of their everyday effectiveness. Furthermore, it can provide insights into their lifestyle choices and personal interests. Physical education in the field of education is guided by established educational standards that are approved in accordance with the law. These standards aim to provide scientifically-based guidelines for physical activity for children and young people, taking into account their health status and level of physical development. Health is a fundamental aspect of an individual’s well-being and greatly influences their overall quality of life. Currently, Ukraine is experiencing a high level of morbidity, particularly among children and adolescents. Specifically, during the schooling years, there is a significant decline in the number of healthy children from the first to the eleventh grade, with a decrease of 3-4 times. The inadequate level of physical fitness among young Ukrainians can be attributed, to a large extent, to the lack of significant incentives for the promotion of sports culture among the younger generation. Consequently, the preservation and enhancement of students’ health, the promotion of physical activity, and the development and improvement of fundamental physical attributes become the primary objectives of physical education for elementary school students. These objectives also represent priority areas for the overall development of our society. To achieve these goals, physical education sessions for elementary school students should address health improvement, pedagogical aspects, and educational objectives in a comprehensive manner. Only through a holistic approach can we effectively exert a multifaceted influence on the development and growth of elementary school students. The aim is to investigate the impact of the developed technology on physical fitness levels of 8-9-yearold students. Material: 8- to 9-year-old students took part in the research. Out of the four surveyed classes four homogeneous groups were formed. Experimental groups consisted of 20 boys and 16 girls; control groups consisted of 19 boys, and 17 girls who were classified into the main medical group for health condition. Results. The process of physical education should be organized in a rational manner, aiming for the comprehensive and balanced development of motor qualities. Achieving high levels of physical fitness serves as a functional basis for expanding the repertoire of motor skills and abilities, while significantly enhancing the functional capacity of the body’s systems. Motor tests are widely used as a common and accessible method of pedagogical assessment. The subjects’ physical preparedness was evaluated through pedagogical testing, which assessed their level of basic motor qualities, including flexibility, strength, endurance, speed, and speed-strength abilities. An increase in the indicators of physical fitness was found in experimental and control groups. But in the experimental groups (boys, girls) - the indicators improved by 46.11%, in the control groups (boys, girls) the indicators improved by 29.76%. Conclusions. The obtained results testify about the effectiveness of technology developed by us, which consisted of two blocks with the priority use of health-improving exercises, as a new tool for the formation of a healthy lifestyle.

In general, aerobic and anaerobic endurance, speed-strength abilities, speed, flexibility, coordination, and technique of movements are important aspects of specific physical training for most types of martial arts. Different types of martial arts may have their own peculiarities depending on their specifics, so it is important to study these aspects for each specific type of martial art. Conclusions. Іt has been established that scientists in their research on the peculiarities of physical training of martial artists paid attention to such aspects as modeling, based on which practical recommendations were given regarding the use of means and methods of physical training in the training process; conducted comparative analysis to identify the peculiarities of the level of development of physical qualities; established the relationship between physical qualities and other types of preparedness; proposed sets of exercises to improve both general and specific physical training.

Achieving optimal physical fitness and health safety in 19-21 year old judo athletes

Background and Study Aim. Physical fitness is crucial for the success of athletes in competitive sports. However, often the impact of physical exertion on athlete health is overlooked. The study aims to investigate the relationship between the level of physical fitness and competitive performance of judokas aged 19-21. Material and Methods. Judo athletes (n=30) participated in the study. The study used video recordings of competitive bouts of 30 judokas aged 19-21 in different weight categories. The athletes were tested for various physical fitness indicators, including strength endurance, coordination abilities, speed-strength abilities, endurance, speed abilities, and flexibility. The SPSS 22 program was used to conduct correlation analysis. Results. The study showed that throws Ippon Seoi Nage, Seoi Otoshi, Kо soto Gake, O Uchi Gari and Ko uchi gar, Ko Soto Gari were the most commonly used techniques across all weight categories. Lighter weight categories favored a throw over the head (Sumi Gaeshi, Tomoe Nage) with an emphasis on speed and coordination, while heavier weight categories favored bending throws (Ura nage) that required strength and flexibility. Conclusions. Based on the study findings, a list of recommended technical judo techniques for each weight category has been proposed. These recommended techniques are closely related to the athletes' level of physical fitness, and coaches can use them to optimize training programs for young judokas.

Changes in Indicators of Special Physical Preparedness in Badminton Players Aged 10–11 under the Influence of Specially Selected Exercises

Study purpose. The study purpose was to determine changes in indicators of special physical preparedness and speed of attacking strokes in badminton players aged 10–11 under the influence of specially selected exercises. Materials and methods. The study participants were young badminton players aged 10–11 (12 boys), whose sports experience was 2-3 years. The study lasted 3 months and included: testing of special physical preparedness and assessment and analysis of the speed of attacking attacking strokes of young badminton players. Results. Analysis of the results of the study showed positive changes in the results of special physical preparedness, accuracy and speed of attacking strokes. The complex development of the speed-strength abilities of young badminton players was determined by the exercises of throwing a ball weighing 1 kg, triple long jump and jumping rope. This was manifested in the execution of attacking strokes from the place and in jumping and moving, but there was a significant increase in results in the triple jump and jumping rope. The development of speed endurance determined the 4-point center-to-center movement exercise, but the results did not change significantly over the course of the study. Accuracy indicators of attacking strokes significantly increased by an average of 2,58%. The results of the speed of attacking strokes also had a significant increase by an average of 29.41%. The use of complexes for training the accuracy of attacking strokes along with targets with a gradual complication of exercises increased the results of test exercises for accuracy and speed of execution. The indicators of the speed of attacking strokes on the left and on the right correlate with each other. The accuracy results of the right hand strokes along the line significantly correlate with right hand strokes along the diagonal and the triple long jump from a place. This indicates the connection of speed-strength abilities with the performance of attacking strokes by young badminton players. Indicators of a triple long jump from a place, jumping rope for 1 min. and throwing a ball weighing 1 kg are significantly correlated with each other, which indicates the complex development of the speed-strength abilities of young badminton players. Conclusions. The presented complexes of special preparatory exercises had a positive effect on changes in the indicators of special physical preparedness, accuracy and speed of the attacking strokes, which makes it possible to recommend them to 10–11-year-old badminton players in the training process.

Proposes the author's method of using the squat as an element of an applied nature, and as a means of developing speed-strength qualities.

Нелинейная зависимость показателей моторного развития от ИМТ у мальчиков-школьников 7–12 лет

Introduction. Childhood and adolescent obesity are associated with impairment of motor skills. However, studies assessing effect of underweight on motor skills as well as the relationship between body mass index (BMI) and motor skills are limited. The purpose of the study was to evaluate relationship between motor skills and BMI in the group of school-aged boys (7–12 years). Material and methods. The data were collected from 7–12-year-old boys (1–5th grade) in the 38 Russia's federal constituent entities of eight federal districts. Height and weight were measured, BMI was calculated. Physical education teachers conducted the testing: endurance 6-minute run test (meters), 3x10 m shuttle run test (seconds), long standing jump (centimeters), forward bend test (centimeters), and 30-m sprint run test (seconds). The dataset contained 54 381 observations. The linear, quadratic and general additive models were built to check relationships between the motor skills and BMI. Results. It was identified that high values of BMI are associated with impaired results of endurance and speed-strength abilities. Male children with a low and normal BMI values did not differ in motor skills. Despite a low level of explained variation of proportion of motor skills, a significant relationship between of motor development and BMI are noted. In the group of 7-year-old male children, the relationship was not identified. Whereas in the group of 8–12-year-old children it has a curvilinear relationship. Conclusion. The relationship between motor skills and BMI is curvilinear (quadratic) in the group of 8–12-year-old boys. Hereafter, the modeling of non-linear relationship between motor development and BMI with other predictors might help identifying the optimum zone of body composition where the adaptation potential will be the highest. It is also allowed to compare this zone in the groups of different ages and sexes.

The Comparison of Unilateral and Bilateral Training Effect to Changes in Speed and Speed-Strength Abilities in Preadolescence Athletes

Introduction: The aim of the study was to compare the effectiveness of unilateral and bilateral training program on changes in the level of speed and speed-strength abilities. Methods: Experimental group 1 (EG1) consisted of 8 young athletes (age = 12.76±1.55 years) and experimental group 2 (EG2) consisted of 8 athletes (age = 12.51±1.59 years) who regularly participate in the training process at a frequency of three times a week. All of our athletes had more than 4 years experiences with regular athletic training 3 times per week prior to this study. During a period of 8 weeks in the preparatory period, such exercises were applied which were performed unilaterally in EG1 and bilaterally in EG2. To determine the effectiveness of take-off training on change in the level of speed and speed-strength abilities, the following tests were performed: relative strength index (RSI), squat jump (SJ), countermovement jump (CMJ), standing long jump (SLJ), 20 m run from standing start. Results: We found out that in the posttest, the athletes of both groups achieved an improvement in the explosive strength of the lower extremities as well as in the acceleration speed. A significant improvement (p<0.05) was recorded in EG1 in SLJ and in EG2 in RSI. The effect size coefficients showed a large effect in RSI in EG2 and in SLJ in EG1. Conclusion: The results clearly did not confirm a higher effect of the unilateral program in comparison with the bilateral program, but indicated a higher efficiency, especially in the take-off explosiveness of athletes with a unilateral training program.

Conclusions. The physical training plays an important role in improving motor skills in sports. In the order to achieve high sports results, the level of physical fitness of an athlete in accordance with the features of specialization is of primary importance. The special physical training of sprinters should include comprehensive education of strength, speed-strength abilities and speed endurance.

Physical fitness of young Greco-Roman athletes under the restrictions of the COVID-19 pandemic

Background and Study Aim. The physical training of young athletes is the basis for future success in competitions. Its effectiveness depends on many factors, among which safe conditions for life support stand out. In the context of the COVID-19 pandemic, there are significant restrictions on the training of young athletes. The aim of the study is the physical training of young Greco-Roman wrestlers in the context of the COVID-19 pandemic.
 Material and Methods. The study involved young athletes (boys, n=20, age 5-7 years (Kharkiv, Ukraine). The experimental group of initial training (n=10) consisted of young athletes of the first year of study (children's sports school). The control group (n=10) consisted of children in the first year of primary school education. The study was conducted for 12 weeks. At the beginning and at the end of the study, a final testing of the level of physical fitness of boys was carried out. Tests were used to determine strength abilities, speed-strength abilities, coordination readiness and flexibility development. The study included all students whose parents agreed to participate in the study. This study was conducted by the Declaration of Helsinki and approved by the Ethics Committee of University.
 Results. Positive changes in the experimental group were observed in tests characterizing the level of development of coordination abilities. During repeated testing, the experimental group was much better oriented in space when performing three rolls. This was manifested in a reduction in the time of their implementation (t=4.091; р˂0.001) and a longer balance in static conditions (t=4.11; р˂0.01). In tests for the manifestation of strength and coordination abilities, there is a tendency to positive changes. However, there was no confirmation of a likely difference between pre-test and post-test (p>0.05). In tests for flexibility, the result remained almost unchanged and even deteriorated slightly. There were very slight positive changes in other studied indicators.
 Conclusions. For the formation of basic physical fitness, it is effective to provide a greater variety of training means and to maximize the focus on the game method of training. The process of training wrestlers of this age should be directed mainly to the development of coordination abilities.

The Effectiveness of a CrossFit Training Program for Improving Physical Fitness of Young Judokas: A Pilot Study.

The aim of this pilot study was to examine the effectiveness of a CrossFit-based training program to enhance the general and sport-specific physical fitness of 10–12-year-old judokas. The study was conducted between September 2021 and February 2022. The pedagogical research experiment was designed to be one complete, annual macrocycle (September–June). The current study presents mid-point data. Twenty male participants (3 years average sports experience; age = 11 ± 0.64 years) were randomly assigned to one of two groups: CrossFit-based training (experimental, n = 10) and traditional training (control, n = 10). Baseline testing was conducted by the researcher and included tests for motor skills and general physical fitness domains including Sweden wall pull-ups and leg raises, push-ups, long jump, squats, burpees, shuttle run, and forward rolls. Judo-specific tests included O Soto Gari and O Goshi throws. CrossFit-based training was implemented twice per week for 15–20 min in the experimental group after usual training. The control group completed traditional methods of physical fitness training for judokas with the same training load regarding time. Experimental group participants significantly improved on leg raises (p < 0.01), push-ups (p < 0.05), and shuttle run (p < 0.001); the control group improved their shuttle run (p < 0.001). Only the experimental group improved on the O Soto Gari (p < 0.01) and O Goshi throws (p < 0.05). Results showed that the use of CrossFit-based trainings had a positive effect on 10–12-year-old judokas’ speed-strength abilities, speed-strength endurance, and muscular strength.

ASSESSMENT OF THE RELIABILITY AND VALIDITY OF TESTING THE SPEED-STRENGTH ABILITIES OF FOOTBALL PLAYERS WITH INFANT CEREBRAL PALSY ON THE MONARK BICYCLE ERGOMETER

In football, including handicapped football, effective play requires players to be able to handle the ball at high speed and perform multiple "explosive" high-speed movements. In disabled football, the problem of developing and evaluating the speed-strength abilities of football players with cerebral palsy is relevant. At present, in the period of active digitalization of education and sports, it is necessary to master and implement digital technologies in sports practice. The study was conducted on the basis of the Zenit football club for the disabled in the city of Izhevsk on an experimental group of 10 football players with cerebral palsy aged 15-18. The article substantiates the necessity and proves the possibility of using the test "bicycle ergometry on MONARK 894E" to measure the speed-strength abilities of football players with cerebral palsy. The basic requirements for tests are considered. Standardization is ensured by testing in the laboratory on the same bicycle ergometer. To check the validity, control motor speed-strength tests were chosen: “Long jump from a place with a push with two legs” and “Run for 30 meters”. Correlation analysis showed a strong statistical relationship between control motor tests and experimental one - "testing on a bicycle ergometer" (multiple correlation coefficient R XYZ =0,87 ). As an indicator of reliability, we took the Bravais-Pearson Correlation coefficient for two measurements on the MONARK 894E bicycle ergometer, which showed a strong relationship between them (r xg=0,99) . On the basis of the GTO standards, a “five-point” interval rating scale was developed according to the indications “maximum alactate power in W” for the experimental test. The conclusions on the conducted research are formulated.
