The data collection technique consists of three parts: First, the initial test with SCQ; Second, treatment with movement modification; and third, the final test with SCQ. The treatment lasted for 16 training sessions, one training session per week, and 120 minutes per session. The training program consisted of warm-up, exercise, and cool-down. Data analysis techniques used, namely normality test, homogeneity test and hypothesis test. Based on the Paired Samples Test output, the Sig.

Its didactic application in various educational contexts allows for many pedagogical uses, which is why the BAPNE method structures and teaches it in a novel way through Neuromotricity. Throughout the years, the learning process of blues and jazz music has been based mostly on imitation with the objective of acquiring knowledge and skills for its correct execution. In this publication we creatively propose activities structured in a specific way to ensure the learning process through sequences that focus on the independence of the lower and upper limbs and the voice. For this reason, we offer in this article specific pedagogical resources to understand and work on the basics of this musical genre with multiple activities created from the 12-bar blues form based on coordination, dissociation and laterality processes among many other aspects.

Materials and methods. The program includes psycho-training practical sessions to develop psychological well-being, stress resistance and psychological harmony, and health fitness training sessions to improve the body's functional state. The program integrates physical and psychological aspects of health. Forty-four female students of the 1st-2nd years of the Yuriy Fedkovich Chernivtsi National University of the Faculty of Physical Culture and Human Health took part in the pedagogical experiment. Results. We found that the program for correcting the physical and psycho-emotional state of female students, which included psycho-training practical classes and health fitness training classes, contributed to a decrease in the values of body weight, waist circumference, hip circumference and pelvic circumference (p<0.05; p<0.001). The results showed statistically significant differences (p<0.05; p<0.001) between the initial and final stages of the study. After using the developed program, we observed statistically significant changes (p < 0.05) in situational and personal anxiety levels. The percentage of female students with a high level of situational anxiety decreased from 27.3 % to 0.0 %, and the average level decreased from 54.5 % to 15.9 %. Personality anxiety also reduced from a high of 43.2 % to 0.0 %, and the intermediate level decreased from 54.5 % to 20.5 %. Conclusions. The results of our study confirm the effectiveness of the author's program “Correction of the physical and psycho-emotional state of female students working with migrant children” in improving the physical development, functional state of the cardiovascular and respiratory systems, and psychological well-being of the participants.

Introduction: Judo is an unarmed martial art characterised mainly by the need to grapple, throw and immobilise the opponent. Over the years it has become increasingly popular, hosting elite competitions, making it necessary to know what injury situations can occur and thus be able to avoid them. Objective: To know the most current scientific evidence on the epidemiology of injuries in elite judo and, secondarily, to study differences between weight categories, sexes and modality.

Results: 11 articles published in the last 10 years with a good methodological quality were included. Conclusion: Elite judokas have a higher incidence of injury in competition compared to training. The knee and shoulder were the most frequently injured joints.
