Efficiency analysis of the speed turns in the crawl stroke swimming.
... точному виконанні усіх елементів повороту. Savchenko M.I., Novyzkiy V.Y. Efficiency analysis of the speed turns in the crawl stroke swimming. Contemporary approaches to improving technique of the speed in the crawl stroke swimming, namely roll-forward turn were considered in the paper. The performance efficiency is defined by the time covering 15 meter distance. ... level of turns performance, the attention should be paid to the exact performance of all the elements of the turns. плавання, швидкісні повороти, кроль на грудях, дослідження. swimming, speed turns, crawl stroke, research. Введение.1 В научной и методической литературе существенное внимание уделено поиску оптимальных вариантов стартов и скоростных поворотов.
Proteomic and carbonylation profile analysis of rat skeletal muscles following acute swimming exercise.
... case they managed to float remaining motionless. The duration of exercise was 30 min. It was previously shown that swimming is an endurance type of exercise and that 30 minutes of swimming are very exhausting for untrained rats . Moreover, swimming is the only kind of exhausting exercise we were able to devise since untrained rats refuse to run on a ... control (C) group and five for the acute swimming exercise group (ASE). Rats in this last group were individually placed in a deep basin (40 cm deep, 50 cm diameter) filled with lukewarm water (3762uC) and devoid of holding devices, so that they were compelled to swim. They were constantly watched and forced to resume swimming in case they managed to float ... is present and well tolerated in mammalian cells. The aim of this investigation was to study skeletal muscle protein carbonylation patterns in rats following acute swimming exercise (ASE). Swimming exercise has been widely used to study biochemical changes associated with forced physical activity in rodents and may help to understand the mechanisms evoking
Sport swimming characteristics in the light of ideas and principles of modern classifications of sports
... сотрудничество, «чувство воды». Kachurovs’kyy D.O. Sport swimming characteristics in the light of ideas and principles of modern classiﬁcations of sports. The known classiﬁcations of modern authors are considered. The criteria of grouping of types of sport are certain in classiﬁcation. The place of the sporting swimming is indicated in different classiﬁcations.
Ultrastructural comparative analysis on the adhesive papillae of the swimming larvae of three ascidian species
... often fixed to the walls of harbours, to the keels and sides of boats and ships. The adult stage is preceded by a larval stage, during which the larvae are free swimming in the marine environment (swimming larvae). This stage lasts from 10 to 12 h, after which the ascidian larvae adhere to a substratum by means of adhesive material. The adherence process ... pasteurized and filtered sea water. Hatching started 18 h after fertilization, at 18 °C. The swimming larvae (6-8 h after hatching) were withdrawn with a pipette and utilized for optical and electron microscopy investigations. Scanning electron microscopy (SEM) A. malaca swimming larvae were fixed in PAF (picric acid-formaldehyde) 1200 mOsm pH 7.5. The fixed ... Institute Press, pp141- 148, 1984.

Srairi, L. Saidi, F. Djeffal and M. Meguellati Abstract— This article deals with the study of a new swimming microrobot behavior using an analytical investigation. The analyzed microrobot is associated by a spherical ... thrust force. Fig.11 shows the distribution of velocity field along the channel containing the swimming microrobot. It is clearly that the high flow velocity appears to be concentrated around the active joint because this latter presents the actuator of the swimming microrobot. In the case of the hybrid tail’s deflection is positive the velocity seems ... Drag force F [nN] D Figure 12. Pareto-optimal solutions of the swimming microrobot design.
