Opis:
The aim of the paper was to evaluate the digit ratio between groups of sporting and non-sporting women and men, and attempt to determine a value typical for athletes of each gender. Additional-ly, the aim was to evaluate relations of the digit ratio with both the somatic structure and motor fitness, which could then be used to improve on sports selection criteria. The research material comprised 22 anthropometric measurements together with results of four motor fitness tests of students active in various sports disciplines. The control group comprised students who had never practiced sport. The sporting students showed significantly lower digit ratios compared to the control group of non-sporting students. Correlations between the digit ratio and features of the body structure were low. Both sexes recorded significant nega-tive correlations between the digit ratio and handgrip strength, as well as with the long jump length. Those with a lower value of the digit ratio had better predispositions to practicing sports.

Opis:
Specific characteristics of sport disciplines require their performers to meet certain demands, also those related to body build. A success is conditioned, among other things, by the morphological structure of competitors. For this cause, their somatic features should be taken into consideration in the selection process. The aim of this research was to describe the level of morphological development and body proportions of swimmers in comparison to their non-practicing peers. What is more, different methods were used to evaluate body tissue composition. The research was based on the measurements of 33 swimmers and 36 non-practicing sport males as a control group, with the average training period of 9 years. The subjects ranged from 18 to 23 years of age. The anthropometric features were examined. Two methods, anthropometric and bioelectrical impedance, were used to estimate the amount of body fat. Athletes performing swimming are characterized by the significant body height, long trunk, wide range of arms and highly developed shoulder girdle. Directed and systematic training has an influence on a great development of the upper part of the trunk and a slight decrease in body fat. The observed differences indicate that depth, circumference and mobility of the chest developed in swimming have a positive influence on the respiratory system. Poor differences observed in the amount of fat in the athletes and non-practicing subjects may result from the fact that the body accumulates fat tissue, used as a good thermal insulation.

Opis:
The aim of the study was to determine if changes in the body build of judo athletes over a time span of 20 years are in line with trends described in the literature. Anthropometry of 60 male and 46 female judokas was performed. Data was collected from two cohorts: the first involved 30 males and 23 females measured in 1994–1995 and the second 30 males and 23 females in 2013. Anthropometric profiles included measurements of skinfolds, height, weight, and body and segment lengths, breadths, and girths. Although relatively identical heights and weights were found between the cohorts, significant differences were detected for body proportion measures. Males in 1994–1995 showed a significantly longer trunk, wider shoulders and hips, and more subcutaneous adipose tissue than the 2013 cohort. Females in 1994–1995 showed a shorter trunk, larger diameters of the trunk in relation to body height, and significantly lower skinfold thicknesses than the 2013 cohort. The direction of changes in the physical characteristics of judokas should be taken into consideration by coaches during training. Combat techniques should be adapted to the morphological traits of the athletes to achieve success and minimize the risk of overloading or injury.

Opis:
Cel pracy. Okres dojrzewania płciowego wyróżnia się dużymi zmianami w cechach morfologicznych i funkcjonalnych ustroju. Jest to również faza krytyczna dla kształtowania się postawy ciała. Celem pracy jest zbadanie zmienności rozwojowej cech posturalnych i składu ciała dziewcząt w wieku 13–15 lat. Materiał i metoda. Wykorzystano ciągłe dane pomiarowe 91 dziewcząt uczęszczających do gimnazjum publicznego we Wrocławiu. Zmierzono masę i wysokość ciała, które posłużyły do wyliczenia BMI. Skład ciała oceniono metodą bioelektrycznej impedancji (aparat BIA 101S fimy Akern, oprogramowanie Bodygram 1.31). W analizie wykorzystano następujące cechy: masa komórkowa, masa pozakomórkowa, masa tłuszczu, masa ciała szczupłego. Na podstawie wielko- ści bezwzględnych wyliczono dwa wskaźniki: masa komórkowa/masa pozakomórkowa i ciało szczupłe/tłuszcz. Ocenę postawy ciała przeprowadzono, korzystając ze sprzężonego z komputerem Posturometru S. Obliczenia przeprowadzono, korzystając z pakietu Statistica 10. Wyniki i wnioski. Odnotowano wzrost masywności sylwetki oceniany wskaźnikiem BMI oraz powiększenie masy komórkowej w relacji do pozakomórkowej. Masa ciała szczupłego w odniesieniu do masy tłuszczu ulega natomiast wyraźnemu zmniejszeniu, co wiąże się z kształtowaniem właściwych dla płci żeńskiej relacji w składzie ciała. Wzrastanie cech posturalnych, takich jak wysokości wyrostków barkowych, dolnych kątów łopatek i wysokości kolców biodrowych tylnych górnych kształtuje się podobnie do zmian w wysokości ciała. Z wiekiem zmniejszeniu ulega nachylenie części krzyżowej kręgosłupa, a powiększa się kąt nachylenia części piersiowo- -lędźwiowej. W kolejnych porównaniach zaobserwowano zwiększenie frekwencji sylwetek kifotycznych (podtyp II), równoważnych (wszystkie podtypy) i lordotycznych (podtyp II). Ponadto odnotowano tendencję do zwiększania się liczby osób cechujących się bardzo dobrą sylwetką. Jedynie w wieku 14 lat zaobserwowano przejściowe zwiększenie czę- stości występowania postaw wadliwych i złych.
Aim. The puberty is distinguished by signifiant changes in the morphological and functional characteristics of the organism’ systems. It is also a critical phase during forming of body posture. The aim of the paper is to examine the variability of development of postural characteristics and body composition of girls aged 13-15 years. Material and Method. There were used the longitudinal measurements of 91 girls attending a public high school in Wroclaw, namely body weight and height, which were then used to calculate BMI. The body composition was assessed by bioelectrical impedance analysis (apparatus BIA 101S produced by Akern, software Bodygram 1.31). In the analysis, the following features were considered: body cell mass, extracellular mass, fat mass, lean body mass. On the basis of the absolute values two ratios were calculated: body cell mass / extracellular mass and lean body/fat. The posture assessment was carried out using a computer coupled with Posturometr S. The calculations were performed using Statistica 10 package. Results and conclusions. There has been noted an increase in the massiveness of body build assessed by BMI and larger body cell mass in relation to the extracellular mass. The relation in lean body mass to the fat was markedly reduced, which is associated with the shape typical for female proportions of body composition. Growing postural characteristics such as shoulder height, infrascapular height and iliospinale superior posterior height is similar to the changes in body height. With age, the slope of sacral part of spine decreases and increases the angle of inclination of the thoraco-lumbar part. In the following comparisons, increasing frequency of kyphotic silhouettes (subtype II), balanced (all subtypes) and lordotic (subtype II) were observed. Moreover, there was a tendency to increasing number of persons with very good body posture. At the age of 14 years, there was noted a transient increase in the frequency of defective and bad posture.

Opis:
In team sports, the varied levels of physical demand associated with different field positions are reflected in the morphofunctional features of the players. The aim of this work was to recognize how the playing position in the team depends on the anthropometric profiles and the strength level of professional handball players. Methods: A body mass, stature, lower and upper extremity length, circumferences and skinfolds were measured in the male professional athletes. The body composition was analysed using a bioelectrical impedance method. Additionally, hand grip and back strength were measured. A statistical analysis was carried out using routinely statistic methods and principal component analysis. Results: Pivot players usually have the most athletic figure in terms of size and weight and relatively short legs. The backs are characterized by the android body type and low subcutaneous fat content, and a large mass of body cells. The backs and pivots have the same strength of back and hand grip. Goalkeepers have relatively long upper and lower limbs and high back and hand grip strength. The wingers are usually slender, have medium length limbs, low body fat percentage, significant extracellular mass and the lowest muscle strength. Conclusions: The results of the multivariate analysis were a notable and valuable addition to the study of morphological and strength differences in a group quite homogeneous like a handball team. The principal component analysis allowed for a reduction of the multidimensional structure to three variables describing body massiveness, strength, and the length and height aspect of the body.
