Opis:
University education is a period of human life when lifestyles or person’s activity are critical to the development of somatic build, while identification of the somatotype allows for corrections or recommendation of effective physical activity programmes. The main aim of this study was to assess selected features of body build and to identify somatotypes of young people at early stages of education at Jozef Pilsudski University of Physical Education in Warsaw depending on the field of study. The study examined 394 students of physical education (PE) and sport (S). Anthropometric measurements were the main research method used in the study. Physical body build (somatotype) was identified using the Heath-Carter method. The ANOVA/MANOVA analysis of variance was employed to determine the significance of differences in values of anthropometric and somatic characteristics between the groups of students. Students of physical education were characterized by a somatotype with a code of 3.08-4.6-2.62 (endomorphic mesomorph). In students of sport, the somatotype code was 3.0-4.58-2.37 (endomorphic mesomorph). Compared to S students, significantly (p < 0.05) higher values (by 10.5%) of the ectomorphy component were found in PE students. The results revealed the need for more research into the somatic build of students of physical education, taking into account the changes in their living conditions (including socio-economic environment), since graduates are expected to promote physical activity in the future. It is also necessary to carry out identical research at the end of studies in order to evaluate the effect of university curricula on the somatic build of students.

Opis:
The trade−off in case of water transport is captured in ecological theory by the safety vs. efficiency concept. As the efficiency of transport of water depends mainly on the dimensions of the con− ductive elements in wood, this paper presents the survey on some methods that allow to quantify the tracheids and vessels attributes including their diameter (tangential/radial, hydraulic), length as well as arrangement (axial, radial). Each trait of conductive elements is briefly described and formula for its calculation is given. Moreover, the usefulness of measurable traits for calculating the meso− and xeromorphy index is presented. Given the fact that the structure of pits and com− plexity of perforation plate (scalariform, ladder−like) are important factors in wood hydraulic resistance, the following parameters were additionally characterized: the pit membrane diameter, pit membrane thickness, pit chamber depth and the number of bars per perforation plate between the adjacent vessel elements.
