The study makes an attempt to response to the three following questions: (1) What are the leading contributors (countries, research institutions, authors and source titles) to research production in the field? (2) What are the core references? (3) What are the leading thematic areas / research fronts?</p> <p><em>Material and Methods:</em> We used the Scopus database as a source of bibliometric data for the research sampling process and employed a combination of bibliometric methods, including research profiling and selected science mapping methods, i.e. co-word analysis and direct citation analysis, in order to achieve the aim of the study and provide responses to the study questions. Science mapping processes were supported with VOSviewer software.</p> <p><em>Results:</em> Research profiling indicates that the main contributors to scientific output on physical activity in the COVID-19 context are scholars and research institutions from countries, which have been heavily affected by the pandemic such as: the United States, the United Kingdom, Italy, Spain, Brazil. Certainly, the reports from China, which was the first nation to suffer from COVID-19 and associated epidemic restrictions, constitute an important input, too. The core references in research on physical activity in the COVID-19 context may be grouped into three categories aimed at: (1) investigating the consequences of pandemic restrictions on physical activity, (2) analysing the outcomes of physical activity for other variables, and (3) providing recommendations for practising home-based physical activity during COVID-19 confinement. Science mapping of the research field conceptual structure indicates the following thematic areas / research fronts in research on physical activity in the COVID-19 context: (1) ‘pandemic and its outcomes’, (2) ‘physical activity during self-isolation’, (3) ‘health behaviour’, (4) ‘food habits’, (5) ‘mental health’, (6) ‘adults and the pandemic’.</p> <p><em>Conclusions:</em> The study contributes to development of physical activity theory by profiling and mapping research conducted in the context of the COVID-19 pandemic. Through mapping the scientific output, the paper points out the leading contributors and core references, and makes an attempt to identify leading thematic areas / research fronts. Discovering the main signposts may be useful for all the researchers planning and designing research within the field. Moreover, mapping research fronts indicates them the topics attracting attention of the academia and potential research gaps.</p> Mateusz Tomanek Andrzej Lis ##submission.copyrightStatement## https://creativecommons.org/licenses/by/4.0/deed.en 2021-06-30 2021-06-30 25 3 136 148 10.15561/20755279.2021.0301 The effect of acute dehydration on agility, quickness and balance performance in elite wrestlers https://sportedu.org.ua/index.php/PES/article/view/1419 <p><em>Background and Study Aim.</em><em>&nbsp; </em>The aim of this study was to investigate the effect of acute dehydration on agility, quickness and balance performance in elite wrestlers.</p> <p><em>Material and Methods.</em> A total of 12 male elite wrestlers, who were student at Selçuk University Faculty of Sport Sciences, whose mean age was 21.58±1.44 years, the mean height of 176.67±5.87 cm, mean body weight of 74.25±17.79 kg, and the mean age of sports 8.92±1,44 years have participated the study voluntarily. After taking the height measurement of the wrestlers participating in the study, their masses were weighted before the training; and body mass index, body fat percentage, muscle mass, and total body fluid were taken with Tanita Bc 730 and agility, quickness (5 m) and balance performance tests were performed. Then, by limiting the fluid intake of the athletes, after losing weight by training, the same tests that were applied before the training applied to the athletes after the training. The study was conducted in accordance with the pre-test and post-test model. T test was used for agility performance measurement of the athletes and 5 m test was used for quickness performance. Dominant foot was determined for balance test and measurement was made via Biodex Balance System. Balance measurements were performed eyes open (EO) and eyes closed (EC), overall stability index (OSI).</p> <p><em>Results.</em>&nbsp; In this study, body weight, body mass index, total body fluid, agility, quickness and balance with eyes open mean values were found to be statistically significant (p&lt;0.05), and muscle mass, body fat percentage, balance with eyes closed found not to be statistically significant (p&gt; 0.05).</p> <p><em>Conclusions. </em>It is believed that acute dehydration negatively affects agility, quickness and balance performances in wrestlers.&nbsp;</p> Sevilay Kaplan Ali O.

For students with poor health, high emotionality of classes and intense rivalry between teams can lead to undesirable consequences for health. Purpose of the research: assessment of the effectiveness of the game method to increase the motivation of students to engage in elective disciplines in physical culture and sports.</p> <p><em>Material and Methods. </em>The study involved first-year students of Sochi State University (Russia) (n=25), with different experience in physical culture and sports. The training sessions (6 hours a week) lasted two academic semesters (9 months) and included outdoor games. A daily «scan» of the current functional state of the students was carried out by heart rate, express scales («Emotional excitement and physical fatigue» and «Well-being-Activity-Mood»). The indicators of general physical fitness of students were registered. The results were analyzed in Microsoft Excel 2010 computer programs. The significance of the change was determined by the Wilcoxon test using the significance level р£0,05.</p> <p><em>Results. </em>The use of a large number of outdoor games and relay games in the classroom contributed to the increase of students' motivation to engage in elective disciplines in physical culture and sports. Which led to almost 100 % of class attendance and improved agility, flexibility and endurance indicators among students (p&lt;0.05). There was a decrease in the indicator in the test «pulling up on a high bar» among young men (p&lt;0.05).</p> <p><em>Conclusions. </em>The study showed new prospects for using the game method in the classroom not only with homogeneous groups of students, but also with students with different levels of physical fitness and health. By manipulating the composition of the playing teams, each of the participants was regularly provided with strong and varied emotions. That increased the interest in students attending classes. The use of the «Express-control» system for the current functional state of the trainees (primarily for students with weakened health) ensured prompt correction of the intensity of physical activity.</p> Inna N.
