Background. The influence of different strength training interventions on strength and competitive performance has been insufficiently examined in elite junior judokas. This study aimed to investigate the impact of different strength interventions in precompetitive training process of elite junior male judokas. Material and Methods. Fifty-three elite judokas (age: 17.22±1.37 yrs, height: 176.34±5.47 cm, body weight: 78.46±6.22 kg, judo training experience: 4.52±0.89 years) performed two different 8-week strength training interventions. Group 1 (n=27) were performed “strength” intervention, group 2 (n=26) were performed “CrossFit®” intervention about 5.3-6.0 hours per week. The base training exercises were as follows: bench press, barbell bench pull and lat pull-down, clean & jerk, snatch, squats and knee flexion curl, pull up. The handgrip strength test, the one-repetition maximum tests, pull up test and competitive performance evalution, were in this study. Results. In post-intervention period, were found that bench press and back squat findings were significantly (p≤0.05) higher in judokas (group 1) as compared to judokas (group 2). There were significantly (p≤0.05) higher pull upfindings in judokas (group 2). No significant differences were observed among the groups with regard to competitive performance values within 3.5 months after post-intervention. Conclusions. This study demonstrated that 8-week of different strength training interventions are not equally effective to increase performance of junior male judokas in specific strength tests and not to change competitive performance of athletes within 3.5 months after strength intervention. The final decision for the particular strength training intervention (“strength” or “CrossFit®”) can be decided according to an judoka's individual challenges during the competitive season.

Aim. The paper aims to justify the use of CrossFit training for improving special physical fitness of judokas. Materials and methods. Male judokas aged from 19 to 20 years (n = 23) who have an experience of at least 6 years were engaged in CrossFit training for 12 weeks. Their physical fitness was assessed using the following methods: SJFT, blood lactate concentration, load test (60 Ippon-Seoi-Nage). The results obtained were compared with the data of recent scientific studies of domestic and foreign experts. Results. Significant (p < 0.05) differences in the results of special judoka tests after 12 weeks of CrossFit training were revealed. A significant decrease in the recovery time of athletes was found. Blood lactate concentration in athletes significantly (p < 0.05) increased. Conclusion. The results of the study prove the effectiveness of regular CrossFit training sessions for judokas. The positive dynamics of the results of special tests indicates an increase in special physical fitness of athletes.

Background: Many methodological problems associated in a sports and fitness environment based on a differentiated approach remain beyond the interest of researchers and developers. The aim of the study was to differentiate physical education classes in school in terms of the individual body mass index of schoolchildren and experimentally prove the effectiveness of its implementation for the harmonious development of youth. Study participants: schoolchildren 15-17 years (n = 64). All the schoolchildren were divided into four groups using the method of body mass index (BMI). Interventions: Pedagogical research was carried out for 7 months at school. The study used tests "Ready for work and defense", BMI, body health indicator and cognitive rate. Main outcome measures. In schoolchildren from the groups (EG1 and EG2), differentiated by BMI for physical education classes, the results on physical qualities improved: endurance and dexterity (p < .05). In CG1, where there was no differentiation, during the experiment 3 schoolchildren with overweight added. Thanks to the experimental intervention in EG1, the schoolchildren kept their initial BMI normal. Separate education of schoolchildren has a positive effect on the cognitive abilities of schoolchildren: comparison of EG1 and CG1 (p < .01), comparison of EG2 and CG2 (p < .05). Findings. The study showed the effectiveness of the BMI in differentiating of youth into groups. If the differentiating physical education at school to indicators of BMI, it will significantly improve the performance of physical and cognitive abilities schoolchildren 15-17 years old and reduce obesity of youth.

Background: During the spread of COVID-19, the need for scientifically based methodological assistance to students when walking and running was most evident in order to improve optimal body functions and maintain health. The aim of the study was to develop a program for monitoring students' walking and running according to the system " 10,000 steps a day " during the spread of COVID-19 and to prove its effectiveness through improving body mass index and improving physical health. Study participants: students regardless of gender (n = 114). Interventions: The pedagogical research was carried out for 4 months. During the experiment, the students of the experimental group (n = 71) carried out self-monitoring of aerobic physical activity, consisting of walking and running, using the author's program according to the principle of " 10,000 steps per day " in daily, weekly and monthly cycles. The study used diagnostics of general physical health, the level of functional readiness to perform loads and body mass index. Main outcome measures. The effectiveness of the implementation of the author's program for monitoring aerobic physical activity of students is statistically significant at p < .01 and p < .05. The implementation of the author's model of independent walking and running is effective only under the condition of systematic fulfilment of aerobic physical loads. Findings. The obtained research data showed that during the period of the spread of COVID-19, an active lifestyle of students, including daily walking and running, is possible and effective for physical health and the prevention of overweight.

Study aim. The specialists note that the latest changes in the rules of judo have a negative impact on the quality of competition between the athletes representing the Russian Federation and the CIS countries. In connection with this the goal of the research was to search for the objective and informative criteria for assessing the level of preparedness of the judoists in Russia and Kyrgyzstan for conducting competitive fights. Another purpose of the research was to analyze the readiness level of the elite judo athletes from Russia and Kyrgyzstan to conduct competitive attacking fight in conditions with the significant changes of the rules of judo competitions based on the selected criteria. Methods. The total number of the judoists – n = 176. The athletes competed in categories less than 60, 66, 73 and up to 81 kg. The time period for the research is 6 years (from 2010 to 2015). The level of the athletes’ readiness was determined by comparing the competitive coefficients (CC) of the judoists. The authors attribute to the significant CC of the number of won and lost technical actions, activity in a duel and time intervals between the attacking actions. CC values ​​were determined by the method of analyzing the competitive judo matches. For the analysis, the specialists were involved: the high-level coaches and international judges – n = 16. The number of the studied judo competition – 4032. Results. Comparative analysis of the CC showed that the athletes of all weight categories reliably (P

Background: The implementation of daily and weekly self-control of individual motor activity, consisting of various speed modes, is not a systematically studied issue. The aim of the study was to develop an individually-differentiated system of self-monitoring of daily physical activity of athletes to increase their motor regime and prove its effectiveness by increasing the level of physical development and health of participants in the experiment. Study participants: Thirty-two subjects from 18 to 25 years of age, engaged for 12 weeks at the Sports Club “Progress”(Glazov, Russia). Interventions: self-monitoring by the participants of this research on a ranking system for diverse types of physical exercises by their correlation to one ordinary step or author's motor unit. Main outcome measures: the author’s self-monitoring system contributes to lowering the body mass index of athletes and developing their endurance. However, its implementation is effective in increasing the level of physical health only among athletes, stably, systematically and without significant deviations in the level of weekly physical activity performing physical activity. The results of the study. the implementation of daily monitoring of motor activity of young people in various motor modes stimulates respondents to increase their motor daily, weekly and monthly activity. Findings. The author’s recommendations for the implementation of continuous self-monitoring will provide feedback to the user of the programme, increase motivation for setting individual goals of amateur athletes and strategies for their further achievement.

Background: The training process to develop the strength of athletes on street exercise simulators with a variable load for powerlifting is not a systematically studied problem. The aim of the study was to analyse the impact of systematic training on street simulators with a variable load on the strength indicators of women and men in powerlifting. Study participants: athletes from 20 to 35 years old (n = 48), engaged in powerlifting at least four times a week, divided into groups: women (n = 24) and men (n = 24). Interventions: Implementation of systematic exercises for women and men in powerlifting on street exercise simulators with variable load for five months. For the performance diagnosis, the powerlifter coefficient (Pl) was applied: (bench press + sed + deadlift) / athlete's mass in kilograms. Main outcome measures: the experiment revealed a positive result in increasing the strength of men (p < .05) and did not reveal a reliable result (p > .05) in increasing the strength in women between the control and experimental groups. Based on an individual comparison of each participant in the experimental group, it was revealed that the implementation of the street training process is significantly (p < .01) more effective in increasing strength in men with a Pl coefficient below the average (< 3.53). Findings. The data obtained are especially valuable in the condition of the activation of street fitness among women and men in the conditions of the closure of gyms caused by the regime of self-isolation during the spread of COVID-19.

Background: In home conditions population of Russian Federation do not have an opportunity to do optimal physical activities during the period of spreading COVID-19. The aim of the study was to develop a system of realization step exercises in home conditions using the independent calorimetry during the period regime of self-isolation and to prove its effectiveness on the indicators of body mass index of the people. Study participants: 62 women and men between the ages of 18 and 45 who have problems with being overweight. Interventions: The study was being conducted in home conditions during 60 days. During the experiment the participants independently carried out the calorimetry, taking into account the consumed calories during the day and burning kilocalories while doing step exercises and another physical activity. For carrying out the calorimetry during the day a formula was developed due to available and simple counting: «N = 0.00168 - 0.098/P», where N - the amount of burning kilocalories per one heartbeat per one kg of body mass, P - heart rate per minute. Main outcome measures: It is defined out that the introduction of step exercises in home conditions with the use of independent calorimetry to the author's system has made a significant impact (p

Today, the key disadvantage of the content of higher education is the underestimation of the role of physical education in the professional development of a future technical specialist. The purpose of this study was to develop a program to develop coordination qualities and abilities, as some of their key physical professional competencies, graduates of technical specialties. The participants of the present study, randomly selected students of higher educational institutions or technical departments of various educational institutions of Russia (n = 386). To determine the effectiveness of the implementation of the author's program, a set of diagnostic procedures were used for coordination and professional-applied indicators. Mathematical-statistical data processing was performed using Student's t-test at p = 0.01 and p = 0.05. Physical exercises on the author's program were presented as components of balance and two main types. Static in the isometric mode of the muscles, causing certain static manifestations to maintain balance, and dynamic, where the balance is maintained in motion. Its application to the development of coordination qualities in an academic lesson in physical education at the university allowed us to statistically prove its more reliable effectiveness compared to the training process for improving other motor skills. The study proved that by means of physical education, it is possible to complement the formation of students' key professional competencies for future professional activities. Such as increasing the efficiency of working at a personal computer, concentrating and switching attention in technical activities and increasing the orientation indicators of the subject in professional activity in a numerical and verbal test. The presented practical experience in the implementation of physical education classes on the development of student coordination can be used in the professional activities of a physical education teacher in a Russian or foreign university on pedagogical interaction with students in a technical college.
