Effects of a 90-minute wrestling training on the selected features of the shape of spine and pelvis under load
Get PDFBackground & Study Aim: The ability to transfer vertical load is conditioned, among others, by the symmetry of the spine in the frontal plane and by the optimal values of angles of physiological curvatures in the sagittal plane. The repeatability and intensity of exercise in modern competitive sports require a great deal of “resilience” of the skeletal system, each discipline having a substantial, specific impact on the load-bearing functions of the skeleton. Sports training can result in the development of disorders associated with excessive load, especially concerning young organisms. The aim of the present study is the impact of the 90-minute wrestling workout on some selected features of the shape of the spine and pelvis under the conditions of increased load for reasons of health of young female wrestlers.
Material & Methods: The examinations were carried out in February 2012 among 30 female wrestlers from the Polish National Wrestling Team (mean ± SD, age: 16,8±1,21 years; body height: 163±5,77 cm; body mass: 54,1±9,28 kg). The method was based on assessing angle values and lengths of the spine in three planes, and on evaluating the pelvis in the frontal and transverse planes. The examination was carried out before and after a specialist training. Evaluation of the selected spinal features was carried out using a test stand for computer analysis of body posture (Posturometer M).
Results: High and medium statistically significant changes occurred among the examined population of female wrestlers as an effect of axial load on the sagittal plane. Insignificant changes were found in the frontal and transverse planes. Very significant changes were observed in the inclination angle in the lumbosacral region (Alpha), the total of partial angles (Delta), the total length of the spine (DCK), the length (DKP), height (RKP) and depth (GKP) of thoracic kyphosis as well as the angle (KLL) and height (RLL) of lumbar lordosis.
Conclusions: Training regimes in base training for female wrestlers should incorporate correction of deficits in ranges of motion in hip and shoulder joints, strength endurance of hip extensor muscles and the muscles of upper thoracic part of body trunk. Wrestling training for female wrestlers should focus more on preventing back pain and stimulating a general endurance of the body
Raising territorial awareness of the students from Gorzów Wielkopolski county (Poland) as part of geographical and historical education
Get PDFThis article contains selected results of research on the course of geographical regional
education and the territorial awareness of pupils in Gorzów county (Western Poland),
a region situated on the border with Germany (the Land of Brandenburg). The paper defines
the basic concepts and terms, and describes a research tool. Students' knowledge about their
own region, the source of this knowledge and the means of its acquisition were set as outcomes.
The state of territorial awareness of pupils including its spatial extent and the nature and
strength of ties were established. While analyzing the results, the authors highlighted the
differences between the declared attitudes of the students of each school, differentiating
them due to the stage of education (middle school and high school) and the place (Gorzów
Wielkopolski, Kostrzyn nad Odrą and Witnica). It was found, that lessons on regional issues
implemented within geography lessons and educational trail such as Regional education
– cultural heritage in the region (Edukacja regionalna – dziedzictwo kulturowe w regionie)
play an important role and contribute significantly to the mastery of complex knowledge
about the region. Beside the formal education about the region a family home is of great
importance, especially in terms of shaping forces of territorial ties. Deficiencies in terms of
regional education were also highlighted. Due to the nature of this article and its small size
authors focuses only on the selected parts of research, in particular the analysis of the diversity of geographical and historical knowledge resources of the surveyed students was omitted
BCI-controlled mechatronic devices, systems, and environments
Get PDFUse of BCIs in patients with severe neurological deficits can improve their quality of life (QoL), provide them increased independence, and possibly increase effectiveness, shorten, and reduce cost of diagnosis, treatment, rehabilitation and care. Many publications have shown evidences for efficacy of BCI-based neurorehabilitation so far, including application as output devices mechatronic modules such as robots and active orthosis. The aim of this study was to investigate the extent to which the available opportunities in BCI-based control of mechatronic devices are being exploited, and discuss their perspectives and directions of further research from the engineers’ point of view

Motywy podejmowania aktywności fizycznej, z uwzględnieniem płci, uczniów liceum ogólnokształcącego im. Władysława Orkana w Bieżuniu
Get PDFThe aim of the study was to show the motives for physical activity by students of the High School named Władysław Orkan in Bieżuń. Also determined whether sex differentiates answer questions.
The high school students are aware that physical activity is an important part of a healthy way of chewing. We are happy to undertake physical activity outside of physical education classes. It has been shown that boys often use forms of organized physical activity, while the girls of the individual. Both boys and girls frequently pointed out that the guiding impetus for making the activity is to improve the health and the desire to improve. For girls desire to achieve a healthy weight was important incentive to undertake physical activity than boys.
The study also confirmed that the lack of desire, lack of time and fatigue are the most common barriers to making physical activity of youth. Replies both boys and girls were mostly questions converge, indicating little relevance to gender in this study.Celem pracy było ukazanie motywów podejmowania aktywności fizycznej przez uczniów Liceum Ogólnokształcącego im. Władysława Orkana w Bieżuniu. Określono również czy płeć różnicuje udzielane odpowiedzi.
Uczniowie liceum mają świadomość, że aktywność fizyczna jest ważnym elementem zdrowego stylu żucia. Chętnie podejmują aktywność ruchową poza zajęciami wychowania fizycznego. Wykazano, że chłopcy częściej korzystają z form zorganizowanych aktywności ruchowej, z kolei dziewczęta z indywidualnych. Zarówno chłopcy, jak i dziewczęta najczęściej wskazywali, iż przewodnim bodźcem do podejmowania aktywności jest poprawa kondycji oraz chęć doskonalenia się. Dla dziewcząt chęć osiągnięcia prawidłowej masy ciała była ważniejszym bodźcem do podjęcia aktywności fizycznej niż dla chłopców
Perception of family relationships and temperament traits in adolescents from transnational families
Get PDFThe aim of this paper is to analyse the differences between perceived family relationships by adolescents from migrant and nonmigrant families and their temperamental traits. In the study 152 adolescents participated, aged 18 years, who formed two groups: criterial and control group in each of them were 46 girls and 30 boys. The following measures were used in the study: Family Relationship Questionnaire (KRR) (Plopa, Polomski, 2008), Buss and Plomin EAS Temperament Questionnaire (Polish adaptation, Oniszczenko, 1997), interview questionnaire prepared by authors to collect demographic data and information about parent's migration. The results of the study showed that girls from migrant families declare higher levels of sociability and fear, while the boys from families of this type are characterized by higher levels of anger. Moreover, results showed gender
differences in perception of family relationships. It was found that girls from families with migrating father perceive a higher level of family communication, cohesion and family identity compared with boys from such families. The above results are not observed in the control group. The results also show the importance of family environment on temperament traits in adolescents from migrant families, which is not observed in the control group (except for the activity)
Formative function of assessment in a psycho-didactical context
No full textThis contribution focuses on the formative function of assessment. The assessment of a student continuously informs about his or her performance, whereby it improves upon his or her learning processes. The formative function of assessment is mainly achieved by feedback resulting from the student‘s performance. This contribution focuses on selected aspects of the formative function of assessment, on the concordance of teaching and assessment goals (and processes) from the perspective of their formulation and the assessment criteria, on the examination of the understanding of the taught subject from the perspective of adopting concepts and their correctness during evaluation, on the didactic approach when working with errors while analyzing the student‘s performance
Variability of indicators of soils' susceptibility on erosion used in the calculation of soil loss from the selected areas
Get PDFIn the predictions of the risks of erosion and protection programs of soil and land from erosion in the aspect of sustainable development of specific areas is increasingly being used an Universal Soil Loss Equation (USLE). However, under specific conditions, in the case of very diversified topography or large diversity of texture of soils, to accurately determine the parameters of this equation can be difficult. In particular because of the putting into service a new classification of soil texture and mineral particles. The paper presents a reference to several field observations mainly in the area of Kujawsko-Pomorskie voivodeship.W przewidywaniach zagrożeń erozyjnych oraz w programach ochrony gleb i gruntów przed erozją w aspekcie zrównoważonego rozwoju określonych obszarów coraz częściej jest wykorzystywane równanie strat glebowych (USLE). Jednak w warunkach szczególnych, w przypadku bardzo urozmaiconej rzeźby terenu albo dużego zróżnicowania uziarnienia gleb, możliwości dokładnego określenia parametrów tego równania mogą być kłopotliwe. Zwłaszcza z powodu wprowadzania do użytku nowej klasyfikacji uziarnienia gleb i utworów mineralnych. W pracy przedstawiono odniesienia do kilkunastu obserwacji terenowych na obszarze głównie województwa kujawsko-pomorskiego
