Somatotypes in sport

Tóth T., Michalíková M., Bednarčíková L., Živčák J., Kneppo P.

The submitted article deals with the evaluation of the somatotype of persons and determination of a suitable somatotype for se-lected sports. In the introduction the method for determining and evaluating a somatotype according to Carter and Heath is characterised. The processes used for calculating the individual components – endomorphy, mesomorphy, ectomorphy – are presented as well as a de-scription of these elements. The calculated components are subsequently put into a somatograph. The evaluation of a somatotype is of great benefit and offers a guideline with the selection of sporting activities; it subsequently helps assign athletes into a suitable posi-tion where they will be able to best develop their talents in view of their bodily construction. In this work two types of sports are evaluated – basketball and bodybuilding. With each sport the measurements which give the prerequisites for the given sport are presented. The selec-tion of the presented sports was made with regard to the different requirements and demands in the scope of bodily constitution. The aim of the presented paper is to assess physical parameters of subjects groups in relation to selected sports (basketball and bodybuilding). Based on the body constitution to determine the conditions for developing the physical condition and success in the appointed sports. Another objective is to compare the rating form and equation methods for somatotype determination. The sample consist 32 subjects with age between 22-28 years of both sexes, who are dedicated to basketball, or bodybuilding at amateur level.

Risk Elements' Input into the Food Chain in Old Loaded Localities

The aim of this work is to evaluate the potential influence of three various sources on soil hygiene and plant production in their vicinity. In the soil of the first observed area in the vicinity of the former Nickel Smelter in Sered, the contents of Cd, Ni, Cu and Co were higher than the background values. Agricultural production grown in this area does not pose any risk to human organism with the exception of Cd in barley grain grown in one locality. The soil of the second observed area in the yicinity of Iron Ore Mines in Rudnany in loaded area of Middle Spis, can be evaluated as highly contaminated with As, Cu and Hg. Potatoes are at the highest risk in this area, but determined contents of risky metals in cereals are also higher than the legislatiye limits of the Food Codex (FC) of the Sloyak Republic. In the third observed locality, Zahorska Lowland, in the yicinity of 5 municipal landfills, the determined total Cu, Cd and Ni soil contents were higher than the background yalues and the metal contents in grain of cereals were higher than the legislatiye limits. The results suggest that the old loaded localities present potential danger of risky elements input into the human food chain.

Celem pracy było zbadanie wpływu trzech różnych źródeł zanieczyszczeń na jakość gleby oraz produkcję roślinną. Zaobserwowana została zwiększona zawartość Cd, Ni Cu i Co w glebie w okolicy byłej huty niklu. Uprawy rolne na tym terenie nie stanowią jednak zagrożenia dla zdrowia ludzi z powodu stosunkowo małej zawartości metali ciężkich. Wyjątek stanowiło ziarno jęczmienia zawierające wysoki poziom kadmu. Na drugim badanym stanowisku - Kopalnia Rudy Żelaza Rudnany, Środkowy Spisz -stwierdzono dużą zawartość As, Cu i Hg w glebie. Największą ilość metali na tym terenie kumulowały ziemniaki. Ponadto w ziarnach zbóż przekroczone zostały obowiązujące w Republice Słowackiej normy zawartości metali ciężkich. Ostatni z badanych terenów to Nizina Zahorska. Na obszarze tym zbadano zawartość metali w glebie pól położonych w pobliżu pięciu składowisk śmieci. Uzyskane wyniki wskazały zwiększoną zawartość Cu, Cd i Ni w glebie oraz przekroczone limity dla zawartości tych metali w ziarnie zbóż. Przeprowadzone badania wykazały, że dawna emisja metali ciężkich do środowiska nadal stanowi źródło zanieczyszczenia żywności.
