Purpose. The study aims to determine the effect of plyometric exercises performed with minimum ground contact time on the maximal power output of the legs and jumping ability. Basic procedures. This study sample comprised 44 non-training students of physical education. Following randomization, the experimental group performed plyometric exercises for six weeks, whereas the control group participated only in lectures. The subjects performed counter movement jumps (CMJ), depth jumps (DJ) and a five-hop test. Main findings. After the completion of plyometric training, an increase in the relative maximal power output (p ≤ 0.001) in CMJ and DJ was observed, whereas the center of mass elevation and the five-hop test distance length did not change significantly (p>0.05). Additionally, the rebound time in DJ was significantly shorter and the range of counter movement in the knee decreased (p ≤ 0.01). Conclusions. Depending on the aim of programme, plyometric training should determine the ways of performing exercises. Methodological guidelines in plyometric training aimed at increasing the maximal power output may be different from indications concerning jumping ability.

Based on the literature, the state of air pollution research in Lublin is presented in historical terms – from the mid-20th century. Due to the lack of developed research methods, there were not many publications of that type in the 20th century. Progress in the study of air pollution in Lublin did not appear until the beginning of the 21st century. In the paper, three main groups of works have been distinguished: 1) on inorganic particulate pollution; 2) on gaseous pollution; 3) on bioaerosols. Among the factors affecting air quality in Lublin and spatial differentiation of pollution concentrations are not only local and incoming emissions from municipal and domestic sources (occurring during the heating season) or all-year emissions from communication routes (local and transit road transport) and industrial sources, but also unfavorable meteorological conditions (e.g. occasional low wind speed and low temperature in winter), hypsometric diversity and building density of the city.

Na podstawie literatury przedstawiono stan badań zanieczyszczenia powietrza w Lublinie w ujęciu historycznym – od połowy XX w. Głównie ze względu na brak wypracowanych metod badań prace tego typu w XX w. były nieliczne. Postęp w badaniach zanieczyszczenia powietrza w Lublinie zaznaczył się dopiero na początku XXI w. W niniejszym opracowaniu wydzielono trzy zasadnicze grupy prac, dotyczące: 1) zanieczyszczeń przez pył nieorganiczny; 2) zanieczyszczeń gazowych; 3) bioaerozolu. Wśród czynników wpływających na jakość powietrza w Lublinie i na zróżnicowanie przestrzenne stężeń zanieczyszczeń istotne znaczenie ma nie tylko lokalna i napływowa emisja ze źródeł komunalno-bytowych (zachodząca w sezonie grzewczym) czy całoroczna emisja z tras komunikacyjnych (lokalnego i tranzytowego transportu samochodowego) i źródeł przemysłowych, lecz także występujące niekorzystne warunki meteorologiczne (np. w okresie zimy występująca czasem niewielka prędkość wiatru przy niskiej temperaturze), zróżnicowanie hipsometryczne miasta i gęstość zabudowy.
