    by Kateryna Mulyk, Aleksander Skaliy, Andrzej Ostrowski, Przemysław Ostrowski

    Background and Study Aim. Modern preschool education focuses on developing not only cognitive skills but also social and emotional competence – key factors determining a child's readiness for successful adaptation and social interaction. Swimming lessons are considered a promising means of developing soft skills, as they combine physical activity, emotional release, and interpersonal interaction. Previous studies demonstrate the positive impact of aquatic environments on communication, emotional regulation, and children's psychoemotional state. However, empirical studies aimed at comprehensively studying the relationship between swimming skills and the development of soft skills in preschoolers are lacking. The purpose of this study was to determine the impact of systematic swimming lessons on the development of soft skills in preschool children and to quantify the relationship between the level of development of swimming skills and the components of soft skills. Material and methods. The study involved 40

    Background and Study Aim. In the modern educational space, active forms of recreational and health activities are becoming increasingly important, promoting physical development, health promotion and the formation of a healthy lifestyle among student youth. Cycling tourism is one of the types of active tourism based on travel using a bicycle as the main means of transportation. It combines recreational, educational and sports aspects, promoting the harmonious development of the individual. This type of tourism has a number of specific features that determine its popularity, in particular among student youth. The purpose of the study is to identify the impact of sports and recreational hiking with bicycles on the state of the cardiorespiratory system of Chinese students. Material and Methods. The study involved 12 male students from Boai County Vocational College, China (the average age of the study participants was 18.9±2.83 years). Students took part in a sports and recreational tourism hike with bicycles, which lasted 8 days from October 20 to October 27, 2024. The study involved monitoring the well-being and functional state of the cardiovascular system (in terms of heart rate) and respiratory system (in terms of vital capacity) of students while participating in a sports and recreational cycling trip. During the hike, heart rate and vital capacity of the lungs were measured every morning and evening (after completing the daily stage), and self-monitoring diaries were kept by each of the hike participants. Results. The analysis of the results of sports and recreational hike with bicycles showed a positive effect of physical activity on the functional state of students. It was found that in the first days of the hike there was a gradual increase in heart rate, which indicates adaptation to physical activity. After a day of rest, heart rate indicators stabilized, and vital capacity of the lungs tended to increase at the end of the hike, which indicates an improvement in the functional reserves of the cardiovascular and respiratory systems of the participants. Thus, cycling tourist hike are an effective means of physical development and health improvement for young people, which confirms the need for their regular implementation in the practice of physical education. Conclusions. It has been established that the cycling sports and health hike has a positive effect on the functional state of the cardiorespiratory system of students. In the first days of the hike, a gradual increase in heart rate was observed, which indicates the body's adaptation to physical exertion. After a day of rest, the heart rate indicators stabilized, and the vital capacity of the lungs (VC) had a tendency to increase at the end of the hike, which indicates an improvement in the functional reserves of the cardiovascular and respiratory systems of the participants.

    by Tomasz Zalewski, Alexander Skaliy, Kateryna Mulyk, Tatiana Skaliy, Andrzej Ostrowski, Witold Kowalski, Maria Adamczyk

    Purpose: evaluate the impact of the implementation of the project “Polish-Kazakh Regional Center for Training, Safety and Rescue” within the framework of the “RITA - Region in Transition” program on the level of knowledge, skills and abilities in the field of medical care. Material and methods. The study involved 646 participants in the first aid training using the BLS algorithm based on the Non-Profit Joint Stock Company “K. Zhubanov Aktobe Regional University.” The study involved: determining the level of stress in the event of being in a situation where it is necessary to provide assistance to a person who has lost consciousness; assessment of the Basic Life Support (BLS) algorithm of actions; assessing the effectiveness of chest compressions on the Laerdal Little Anne QCPR manikin. Results. It was revealed that after completing the BLS training, the project participants’ stress level, if they find themselves in a situation where it is necessary to provide assistance to a person who has lost consciousness, has decreased significantly. Based on the results of testing the assessment of the BLS action algorithm, it was found that the level of knowledge and skills in providing first aid improved by 75,9%. It was found that the efficiency of pressing on the chest of the manikin improved by 53,3% after training. Positive changes in all indicators indicate that BLS training using the KISS (keep it short and simple) methodology is accessible, understandable and effective for all project participants. It was found that indicators of stress level, BLS action algorithm and QCPR effectiveness both at the beginning and at the end of the study have a correlation dependence. Reduced stress levels occur due to increased preparedness among participants and contributes to more effective care delivery. The reliable nature of the connections confirms the assumptions made and gives grounds to assert that the goal of the project has been achieved. Conclusions. The results obtained prove the effectiveness of the implementation of the project “Polish-Kazakh Regional Center for Training, Safety and Rescue”. Thanks to the events carried out, a large number of voters approved the formation of comprehensive competence to provide first aid in the case of Sudden Cardiac Arrest. As a result of the trainings, participants acquired practical skills in carrying out resuscitation measures, mastered the algorithm for providing assistance, and increased the level of confidence in their own theoretical knowledge and practical skills. This project proves that social activism and collaboration between scientists can be very effective and lead to systemic change. In Kazakhstan, where high rates of Sudden Cardiac Arrest are recorded, thanks to the implementation of international projects, a number of events and trainings have already been introduced, largely popularizing the ability to provide first aid, which will further influence the activities of governmental and non-governmental organizations. The results obtained allow us to recommend similar projects for implementation in other countries

    by Kateryna Mulyk, Aleksander Skaliy, Nurlan Mukazhanov, Andrzej Ostrowski, Volodymyr Paievskyi, Anatoliy Abdula

    Background and Study Aim. Based on research results, it has been established that various types of sports games and sports and health tourism are the most popular among schoolchildren and students. Various movements and actions in volleyball have great health benefits. They help strengthen the musculoskeletal system, improve overall metabolism, increase the activity of all organs and systems of all organisms and are a means of active recreation. In the conditions of hiking trip, a particularly important role is played by the high adaptive abilities of the body, based on the reactivity and lability of functional systems. The purpose of the study was to determine the influence of volleyball and sports and health tourism on the physical, mental and social health of schoolchildren and students. Material and Methods. The study involved 60 schoolchildren and 60 male students. Schoolchildren and students were divided into two groups (30 people in each group), who were engaged in volleyball and sports and health tourism sections. The study used methods to assess physical, mental and social health; level of satisfaction with quality of life; well-being, activity and mood. Results. The best indicators for physical health among schoolchildren and students were obtained in favor of those involved in sports and health tourism (p<0,05-0,01). The best level of mental and social health was found among students who spent a year studying in sports and health tourism sections (p<0,05-0,01), while schoolchildren, on the contrary, had the best results obtained from those who were involved in team sports. Conclusions. The results of the study indicate that playing sports games (volleyball and basketball) and sports and health tourism have a positive effect on the physical, mental and social health of schoolchildren and students. These studies indicate that school-age children are characterized by team sports, which are more emotional and serve as an effective means of physical education for this age category. Students are more interested in organizing classes in sports and health tourism, which include participation in competitions in various types of tourism and weekend trips held in the fresh air. Thus, it can be stated that the influence of sports games and sports and health tourism on the psychological sphere of schoolchildren and students contributes to positive changes in their psyche, creates a persistent, cheerful, active state, generating positive emotions and ensures increased satisfaction with life in general, which in turn affects the health of children and youth.

    by Alexander Skaliy, Kateryna Mulyk, Zhijing Ban, Andrzej Ostrowski, Olena Anosova

    Background and Study Aim. In the conditions of hiking trip, a particularly important role is played by the high adaptive abilities of the body, based on the reactivity and lability of functional systems. Of particular importance is the assessment of the functional state of the cardiovascular system of students when participating in a mountain hike. The purpose of the study is to evaluate the effect of physical activity on the state of the cardiovascular system of students in the process of overcoming a mountain hiking trip. Material and Methods. The study involved 30 students aged 18-22 years old who were involved in various sports at the amateur level. The hiking trip lasted six days and covered 114 km. Canyon SportMaster hand-held heart rate monitors were used to determine the power of the students' cardiovascular system. When overcoming climbs during a mountain hike, the rate of heart rate recovery after physical activity was determined (heart rate indicators were recorded before the climb, at the end of the climb, and two minutes after the climb). Results. Analysis of the data obtained showed that the power of the cardiovascular system changed during the hiking trip. The third day turned out to be the most difficult day; the level of power of the cardiovascular system on this day was 76% of the maximum. In all subsequent days, the tourists’ cardiovascular system coped with the stress much better. The indicators obtained on the last day of the hike indicate the adaptive changes that occurred in the athletes’ bodies. Conclusions. It was found that on the first day of the hike the cardiovascular system worked at a sufficient level. In the next two days, there was a decrease in recovery rates and a deterioration in the performance of the cardiovascular system. This is explained by fatigue after the first day, and the fact that the body has not yet had time to work and adapt to unusual loads. Analysis of the last three days of the hike clearly indicates that the body systems have adapted to the stress and environment. Heart rate recovery indicators went up sharply, and the heart rate system worked at only 65% of maximum power. Also, important factors that also need to be taken into account: the weight of the backpacks, the length of the distance, weather conditions, temperature conditions, the psychological atmosphere in the group, equipment, etc.

    Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

    Background: Ju-jitsu training has to be comprehensive in terms of training intensity, developing a wide range of physical fitness and learning multiple technical skills. These requirements result from the specificity of the competition characteristic of the sport form of this martial art. The aim of this study was to evaluate the aerobic capacity and special physical fitness of ju-jitsu athletes at the highest sports performance level and to determine the relationships between special fitness and the indices of technical and tactical skills. Methods: In order to determine the current level of special fitness of the athletes, a set of karate fitness tests were used, namely, the Special Judo Fitness Test and the Kickboxer Special Physical Fitness Test. Furthermore, maximal oxygen uptake (VO2peak) was measured using a graded exercise test in a group of 30 sport ju-jitsu athletes at the highest level of sports performance. To evaluate the level of technical and tactical skills, an analysis of recordings of tournament bouts was carried out, and, based on the observations, the indices of effectiveness, efficiency, and activeness of the attack were calculated. Results: Individuals with higher fitness were more active and effective in the attack. The special efficiency indices showed significant correlations with the technical and tactical parameters. Better fighting performance was dependent on the speed of the punches, kicking range, and the results of the special fitness tests. Conclusions: To achieve greater efficiency and effectiveness of sport ju-jitsu, the training process should be based on comprehensive motor development and an optimal level of special fitness.
