Hlavínová, Tereza ; Břečková, Gabriela (advisor) ; Levitová, Andrea (referee)
A B S T R A C T T I T L E The Impact of physical activities in water on joints movements of seniors. O B J E C T I V E The evaluation of the impact of physical activities in water on joint movements of elderly people. From the data available which measures the movements of shoulder and hip joints at the beginning, in the middle and after the training session, we identify whether there are some changes in the range of movements available of the tested joints. M E T H O D The efficiency of swimming program whose duration was 15 weeks was evaluation by measuring the improvement of movements possible of shoulder and hip joints. There were two groups of elderly people tested. The first group consisted of university students taking courses for elderly people, the latter group consisted of elderly volunteers. Both programmes had the same content. R E S U LT S After the swimming program finished, there were measurable changes in the range of joint movements all participants could perform. In majority of cases these changes were positive (i.e enlargement of the range available), in some case the rotation of the joint in certain movements remained same but there were some elderly people whose range of joint movements was reduced. Overall, the range enlargement was estimated to be higher by 5 - 10ř. K E Y W O R D S...

Habitat shifts to aquatic environment and back to dry land in the evolution of Coleoptera
Sýkora, Vít ; Fikáček, Martin (advisor) ; Král, David (referee)
The order Coleoptera (beetles) includes both terrestrial and aquatic species. The whole order as well as for all suborders (Archostemata, Myxophaga, Adephaga and Polyphaga) in ancetrally terrestrial. Habitat shifts occured in all suborders except Archostemata. A single shift to aquatic environment is probable in Myxophaga and Adephaga, multiple independent shifts from aquatic to terrestrial environments took place in Polyphaga. Multiple secondary habitat transitions back to terrestrial life style occured in Adephaga, Myxophaga and Polyphaga. However, phylogenetic relationships and/or detailed habitat requirements of adults and larvae are still unknown for many groups. That is why a reliable reconstruction of the evolution of habitat transitions between aquatic and terrestrial environment is still impossible in many cases. Key words: Coleoptera, habitat shifts, aquatic environment, terrestrial environment, evolution, phylogeny, biodiversity, morphology, adaptation

Effect of water temperature on the electrical activity of muscle
Novotná, Petra ; Pánek, David (advisor) ; Jalovcová, Miroslava (referee)
Title: Effect of water temperature on the electrical activity of muscle Objective: Main objective of this work is to determine the spatiotemporal changes in muscle activation depending on different properties of the environment. All this at a defined muscle power output. Measured by hand dynamometer. Methods: This is a case study. Is processed and analyzed the relationship of the forearm muscles against the aquatic environment (different temperatures - 15 řC, 24 řC and 35 řC) and against dry. Muscular power output is defined and measured by hand dynamometer. Muscular power output was determined as isometric contraction flexors of wrist and fingers of dominant hand. It all in three different modes. The research group were included 5 healthy individuals (3 women, 2 men). As objectivization method was determined surface electromyography. Findings: There is no influence of water temperature (15 řC, 24 řC and 35 řC) on spatiotemporal activation of muscle. It all at a defined muscle power output. There is also no changes on spatiotemporal activation of muscle in aquatic and dry. Keywords: muscle contraction, temperature, water environment, surface electromyography, Water Surface EMG

Evaluation of EMG Activity of the Shoulder Girdle Muscles during Exercises with Thera-Band in Aquatic Environment and on Land
Holländerová, Dita ; Pavlů, Dagmar (advisor) ; Pánek, David (referee)
Title: Evaluation of EMG Activity of the Shoulder Girdle Muscles during Exercises with Thera-Band in Aquatic Environment and on Land. Objective: The main goal of this thesis is to determine a degree of muscle activity of upper trapezius muscle and other selected muscles in the aquatic environment and on land and to compare the values. Furthermore, to determine whether the upper trapezius muscle activates in the aquatic environment later than on land, compared to other selected muscles. Methods: This is the case of study, where the degree of muscle activity and the onset of activation of the upper trapezius muscle and other selected muscle is analyzed and then evaluated during shoulder abduction in two different environments using elastic resistance strength (yellow Thera-Band). As an objectification method surface electromyography had been chosen. To ensure the same set of initial conditions the abduction was performed in sitting position. The same chair was used in water and on land. Four female participants part in the experiment. Findings: The degree of muscle activity of upper trapezius muscle in the aquatic environment significantly decreased. It wasn't confirmed, that the upper trapezius muscle has been activated later in water than on land. Timing of selected muscles in aquatic environment...

Host-parazite coevolution in aquatic environments
Hubová, Jana ; Petrusek, Adam (advisor) ; Votýpka, Jan (referee)
Antagonistic coevolution is a major driving force in the evolution of host and parasite. Parasites create on their host a time delay, negative frequency-dependent selection, which leads to oscillations in both genotypes of antagonists, as suggested by the Red Queen hypothesis derived for coevolution of host and parasite. The most commonly used systems for the study of host-parasite coevolution in an aquatic environment are (thanks to their features): diatom Asterionella and chytrid Zygorhizidium, aquatic snail Potamopyrgus and trematods Microphallus, water fleas Daphnia and their microparasites. Coevolution between host and parasite causes a number of phenomena, such as maintenance of genetic polymorphism, temporal oscillations of genotype frequencies, the persistence of sexual reproduction, parasite local and host adaptations. This thesis summarizes the current knowledge on the coevolution of the above-mentioned three host-parasite systems in the aquatic environment. Key words: Red Queen hypothesis, host-parasite coevolution, negative frequency-dependent selection, aquatic environments, Asterionella formosa, Potamopyrgus antipodarum, Daphnia.

Influence of exercise in aqueous media on obese children
Holinka, Leoš ; Přibyl, Ivan (advisor) ; Hájková, Jana (referee)
The goal of my thesis was to design and realise an active programme for obese children in water surroundings, who underwent five week lasting medical programme in Státní léčebné lázně Bludov. The tested group consisted of 7 children, who took part in an hour long exercise in water surroundings twice a week deliberately. Having used questionnaire methods we discovered the difference between the attitude of obese children to exercise in water and to activities in the gymnasium. Further, we dealt with the influence of activity in water surroundings comparing the input and output values of fat by tested and control group.

Assessment of probable causes of corrosion damage of a glass-shaping mould
Jíša, Jakub ; Pantělejev, Libor (referee) ; Man, Ondřej (advisor)
The aim of this thesis was to characterize briefly the issue of electrochemical corrosion in the aquatic environment with a focus on cast-iron corrosion and then decide whether the observed damage to the glass-forming mold could arise in the course of two days. A simple corrosion experiment was made in which samples of cast-iron were exposed to the shower of water for 48 hours. Corrosion damage under simulated conditions did not reach the level of damage of the mold.

Variability of mercury concentrations in adult and juvenile fish
HOLAŇ, Viktor
The thesis compares variability of mercury concentration among adult and juvenile fish in order to streamline monitoring of water environment contamination. In terms ov thw thesis there were monitored two localities: Labe Děčín and Labe Kozly. Adult fish were caught usingdeep-water electrofishing equipment and juvenile fish were caught using back-pack electrofishing equipment. Two variations of mercury concentration were compared, one in muscle of particular adult fish species, second in whole bodies of juvenile fish. Mercury concentrations were also compared among particular juvenile fish fish species in particular localities. All analyses were performed using spectrophotometer AMA 254. It was proved that analyses of juvenile fish are suitable and more cheaper than analyses of adult fish, when it comes to monitoring.
