Oviposition behaviour of the soil mite Veigaia cerva (Acari: Veigaiidae).

Abstract: We observed the oviposition behaviour of the soil mite Veigaia cerva (Kramer) (Acari: Veigaiidae) using continuous video-monitoring. Five phases could be recognized. Phase I involved inspection of the substrate. In phase II the female rhythmically moved her gnathosoma and first pair of legs. After an inactive phase III, the soma was raised (IV), and the egg was laid (V). In the actual egg laying three sub-phases could be distinguished: internal egg movement, placing the egg in front of the gnathosoma, and depositing the egg using the chelicerae. The palps and first pair of legs were used to position the egg between the chelicerae. The whole process took on average 333 ± 22 s.

Detailed analysis of a 240-second cycle ergometric test in middle-distance runners aged 16-19

Abstract: Introduction. Middle-distance runs are endurance events that include the distances from 600 m up to 1609 m. The objective of the research is to determine work capabilities in acid and lactic conditions, measured by means of a 240-second test in young junior (16-17 years of age) and junior (18-19 years of age) runners at middle distances and to compare maximum lactate concentrations and maximum heart rate after 60-second and 240-second tests of the subjects. Methods. The research included 20 competitors aged 16-17 and 12 competitors aged 18-19. During the test period all subjects were training in the Kujawsko-Pomorskie province sport clubs. In order to determine work capabilities in acid-lactic conditions, a 240-second cycle ergometric laboratory test was applied. The obtained results were worked out using basic descriptive statistics: arithmetic average (M), standard deviation (± δ), minimum (min) and maximum values and coefficient of variation (V%). Results. The results obtained made it possible to characterize the subjects in terms of work capabilities at a high level of lactic acid in blood during middle-long effort. An in-depth investigation of the collected material might prove useful when planning training loads for work on special stamina. Conclusions. A set of criteria presented in the paper, detailing work and power obtained during a 240- second cycle ergometer might be used by trainers in a sport training process to assess individual function predisposition.
