STROKE PARAMETER ANALYSIS PERFORMING A COMPETITION DISTANCE (200 M) ON WATER
Get PDFCanoe sprint is a water sport (under natural conditions, it takes place on water); therefore, for the most part, research is carried out under laboratory conditions, when the load is performed on various special exercise machines (ergometers) that try to simulate natural conditions as closely as possible since doing research in natural conditions is very challenging. However, technological development and recently available specific devices allow to go forward and overcome these challenges. The aim of the research is to provide information on stroke parameters for a 200 m distance with maximum effort in natural conditions of the sport – on water, provided by the only device currently available on the market that measures the power and force applied to the stroke, and result comparison with similar research done by other authors. Dynamometry was used as the primary method to obtain indicators on power and force applied to the paddle, using a specialized device – canoe sprint power meter (One Giant Leap, Nelson, New Zealand). The average force value to the brace in a 200 m distance between all 87 braces was found to be 456.2 ± 8.7 N
COMPARISON OF COMPETITIVE ACTIVITY INDICATORS AT 100 M DISTANCES OF LATVIAN AND EUROPEAN SWIMMERS
Get PDFThe research aimed to study the performance characteristics of male and female finalists at a 100m distance when swimming at the Latvian swimming championships in a period from 2018 to 2020 (in the 50m pool). 262 final heats got analyzed. The results of the 3 best Latvian swimmers, males=36, and females-36, at each 100m distance (freestyle, breaststroke, backstroke, and butterfly) at championships in 2018, 2019, and 2020 have been analysed. The parameters for overcoming competitive distance: competitive result in the 100-meter distance; the start reaction time; time for the 15 meters mark; speed to the 15 meters mark; the time of the turn 5 meters up to the wall and 15 meters after the turn; underwater distance and time after the start and after turning; time of “clear” swimming. The obtained results were compared to the characteristics of overcoming the same competitive distance by the finalists of the European Championship 2016. As a result of comparative analysis, statistically, significant differences were found in such parameters of competitive activity as the overall result, overcoming of starting and turning parts, and the distance covered under water after the turn and start. Statistically significant differences were not found in the reaction time to the start signal and in the speed of “clear” swimming. The comparative analysis of the performance characteristics of the European Championships finalists showed possibilities for further improvements of Latvian swimmers. The aim: is to determine the performance parameters of the Latvian best swimmers and compare them with the same parameters of the finalists of the European Championship 2016.
PROFESSIONAL SELF-CONCEPT OF NURSES AND WILLINGNESS TO REMAIN IN THE PROFESSION
Get PDFThe professional self-concept of nurses, who make up the majority of medical practitioners and who participate in the implementation of public health policy, plays an important role in job satisfaction, productivity, which leads to patient satisfaction and development of the profession. Whereas, nurse job satisfaction affects nurse\u27s future plans related to willingness to remain in the profession. Nursing self-concept is shaped and influenced by many different factors, one of them global self-esteem. The aim of the study is to investigate the relationship between the factors forming the professional self-concept, self-esteem and willingness to remain in profession of practicing nurses. The results revealed that there are statistically significant links between some groups of socio-demographic data: age and self-esteem, level of education and self-esteem, as well as the desire to remain in the profession. Statistically significant differences have been identified between respondents\u27 answers according to age group, education level, length of service and certificate in relation to different sub-scales of self-concept.
PERFORMANCE AND TRAINING PROGRAM CHARACTERISTICS IN ELITE YUNIOR FEMALE ROLLER SKIER FROM 2021 SEASON: A CASE REPORT
Get PDFThe purpose was to evaluate the training program, body mass composition, aerobic performance laboratory and field test results, blood hormone concentration in elite junior female roller skier in successful competition season. Methods. Totally 206 training sessions (278 training hours) were analysed during six months (from April till September). Athlete wight and body fat changes were monitored, laboratory tests on a treadmill and field tests were performed and concentration of hormones in the blood was detected. Results. A polarised training intensity distribution was observed. The highest volume of training workloads (70 training hours per month) was achieved in the last month before start of World cup season, this change corelated with change in blood testosterone levels. Heart rate decreased by 7.51% at the anaerobic threshold load intensity and by 10.1% at lower intensity loads. Peak oxygen uptake (VO2max) of 49 ml/kg/min was reached in laboratory test. Increase of lean body mass by 2.4 kg was observed. The progress in 3000m running race time was detected from 14:30 minutes in the beginning of April to 13:16 minutes in June. Conclusion. VO2max in junior elite female roller skier is low in comparison with cross-country skiers, but the training workload intensity and volume are comparable with skiers. This research shows insight in top junior level female roller-skiers physiology and training, but specific values determining the success of this athlete are still to be determined if compared to traditional cross-country skier.

ANALYSIS OF THE DYNAMICS OF PROSTATE CANCER DIAGNOSIS IN THE REGIONAL HOSPITAL DURING THE PERIOD 2018 – 2022
Get PDFProstate cancer is a serious medical problem around the world. In many parts of the world, prostate cancer is the leading cause of morbidity and the second leading cause of death immediately after lung cancer. The largest proportion of cases of malignant prostate tumors is in men aged 60-80 years. The Latgale region has the highest proportion of seniors in the population (22.1%). The aim of this research was to evaluate the dynamics of primary diagnostic results over 5 years period in Daugavpils hospital patients. Objects of the study are 546 patients (men) aged from 47 to 88 years who had a PSA marker and prostate biopsy results (histological responses) collected in the period from 1 January 2018 until 1 July 2022. For quantitative evaluation of histological data, the Gleason score was used, as well as its derivative GRADE (degree of malignancy). To assess the dynamics of the quality of diagnostics of prostate cancer over 5 years, the correlation coefficient between the data on the Gleason score of newly diagnosed cancer and the 5 years period of the study was used. Relationships between PSA values, Gleason scores and patient age were also assessed. The SPSS data Statistics program was used for calculation. Difficulties in diagnosis in older patients were discussed

ADAPTATION PECULIARITIES OF HIGHER EDUCATION STUDENTS IN CRISIS CONDITIONS
Get PDFDramatic events related to the Russian-Ukrainian war shook up not only Ukraine, but the entire civilized world. The war exacerbated not only economic, political, and demographic problems, but also defined as priority tasks the physical rescue of a person, the preservation of his life and health, comprehensive assistance in migration, arranging life and living in critical conditions, overcoming fear and hopelessness. Russia broke all the rules of life on the planet and distinguished itself by atrocities, murders of civilians, looting, and rape. Ukrainians, who are faced with the challenges of life and death today, are looking for ways to preserve not only their territories, above all, their language, culture, education, and authenticity. Our desire for global and European values requires not only the support of the Armed Forces, but each person in his place to work to the best of his ability to support public life in all its dimensions. Education also requires new approaches to content, values, psychological and pedagogical principles, organizational forms, and tools to overcome the challenges facing Ukraine today. In the center of attention of the higher school now is the student whose life, in addition to traditional challenges, has been complicated by war, uncertainty about the future, confusion, despair, a difficult economic situation, the lack of an opportunity to provide basic needs, distance learning, etc. All this, as evidenced by our survey of students of higher education, often leads to maladaptation, depressive states, disappointment, apathy, anxiety, etc. Therefore, the stated situation actualizes the problem of finding optimal ways of adaptation of higher education students in crisis conditions, which will be outlined in our research. In order to identify the peculiarities of students` adaptation to crisis conditions, we conducted a study related to various aspects of their life. It included the possibility to receive psychological support during a crisis period. It is associated with a pandemic and war; awareness and understanding of external and internal factors of crisis conditions that influence student life; the process of adaptation to distance learning in crisis conditions; elucidation of the reasons that negatively influence/influenced the distance learning process in crisis conditions; determining positive potential of distance learning in crisis conditions; evaluation by students of educational process effectiveness in crisis conditions.

THE CONCEPT OF LEARNING TO LEARN IN THE CONTEXT OF MUSIC EDUCATION
Get PDFIn the context of lifelong learning, the importance of learning to learn is increasingly emphasised. There have been different views on defining the concept of learning to learn and the final definition has not been available yet. Researchers have made attempts to define and explore this concept in different areas. Sometimes they come from quite different epistemological and logical backgrounds. Learning to learn has been extensively analysed in the scientific literature and has been described in various ways. Using a literature review approach, this article presents a theoretical analysis on how the concept of learning to learn is understood in general music education, with the aim of discovering the specifics of learning to learn in this context. The role of planning, collaboration, reflection, and self-assessment in music education has also been identified in the study.
