Introduction: Physical activity is one of the essential factors in maintaining health and healthy body weight. As the pandemic of overweight and obesity continues to grow, it is crucial that children follow the recommended standards for physical activity from an early age. Both overweight and obesity are associated with an increased risk of diseases such as diabetes, hypertension and cancer. Excess body weight in childhood favors the maintenance of this problem in adulthood. Purpose of the study: The aim of the study was to evaluate the level of physical activity among school-aged children, to analyze individual components of body composition and to determine the influence of physical activity on maintaining normal body weight. Material and methods: We undertook to assess the physical activity levels of 245 school-aged children (7-15 years). was examined and analyzed the body composition of the study participants, and then the correlation of the level of physical activity with the maintenance of normal individual components of body composition was calculated. Results: Only 61% of childrens were characterized by normal body weight appropriate for their age. In the group of children declaring participation in extracurricular sport activities, the number of subjects with normal body weight was 65%, while in the group of subjects who declared no extracurricular activity of any kind, the percentage was 58%. Conclusions: It turned out that the number of children engaged in physical activity outside of school is alarmingly low. The study showed that children who participated in any extracurricular sport activity were more likely to maintain normal body weight and less likely to be overweight or obese.

Opis:
The objectives of this study were to see if the general performance of kayakers depends on the level of their specific preparation and to identify the parameters of general preparedness that determine specific preparation. The subjects were divided into 3 groups on the basis of the result of a specific test: paddling over a 2000-m distance. Group 2 included kayakers whose paddling time did not exceed ±1 SD for the whole sample, while group 1 included the best athletes with paddling times shorter than –1 SD and group 3 individuals who needed more than +1 SD to cover the 2000-m distance. The study included 55 junior flatwater kayakers, represented various sports classes. All athletes manifested a similar level of endurance running, power and endurance pull and push barbell, 30 m running tests. The only differing characteristic between all groups was the level of asymmetry in distance of ball throw from sitting position of at 29%, 45% and 66% in each group and paddling for 2000 m time. All athletes manifested a similar level of general fitness preparation. The only differing characteristic between all groups was the level of asymmetry in distance of ball throw from a sitting position.

Opis:
This paper presents the Late Glacial stage of the development of the Białe Ługi peatland in the southern Holy Cross Mountains, based on a comprehensive palaeoenvironmental data. A complex analysis of palynology, Cladocera, sedimentology, geochemistry and 14C dating were used. Organic deposition was initiated during the Oldest Dryas. The sedimentary record of the aquatic and terrestrial ecosystems reflects considerable difference between cooler (Oldest, Older and Younger Dryas) and warmer phases (Bølling and Allerød). Periods of intensified interaction between aeolian processes and peatland are related to stages of disappearing vegetation and changes in aquatic invertebrate communities. We therefore suggest that peatlands were created as a result of local lithological-structural, tectonic, hydrogeological and morphological conditions, and the peatland development rate was largely influenced by changing climatic conditions, which determined local vegetation development, intensity of denudation processes and water level changes. The results validate significance of selection and use of several methods, as well as value of biogenic deposits from the Białe Ługi peatland as archives of past climate change in the Małopolska Upland. Relatively stable water conditions and uninterrupted biogenic sedimentation in the Late Glacial that were provided by the geological structure and relief suggest the studied peatland is a leading one in the region.
