Zooplankton response to a change of water chemistry and amount of food during the recovery of lakes from acidification
Bartošíková, Martina ; Stuchlík, Evžen (advisor) ; Šorf, Michal (referee)
Anthropogenic acidification has affected assemblages in thousands of lakes in North America and Europe. It turned out that, during the acidification, the number of zooplankton changed and also the species composition of their assemblages, at some sites there was also the total disappearance. The main reason was a decrease of pH, wash out toxic aluminium and a change of trophic status. The rate and extent of biological recovery after restoring the pH in acidified lakes varies considerably across regions. Recovery of aquatic communities is significantly lagging behind the recovery in chemistry. Some zooplankton species are nonetheless able to quickly colonize recuperating ecosystems and in many acidified lakes again started to appear native species that have disappeared during acidification. The return of indigenous species, however, can be blocked acid-tolerant occurrence of species after species extinct occupied empty niches. Zooplankton can be affected by water chemistry directly, but also indirectly by the quality and quantity of food. An important factor is the possible spread of colonizing species. However, the relative roles of these factors in regulating recovery may be difficult to determine. Key words: zooplankton, acidification, water chemistry, aluminium toxicity, phytoplankton

Škoda, Jan ; Baláš, Jiří (advisor) ; Hojka, Vladimír (referee)
Title: The influence of water temperature on the rate of recovery during repeated isometric exercise. Objectives: The aim of this thesis is to assess the effect of water temperature on immersion of forearm to water for the sake of speeding up the recovery process during repeated isometric performance. Methods: Five male subjects from the students of FTVS (average age 22 ± 3 years) underwent three meaurements with repeated exercise to exhaustion with various kinds of rest periods. The exercise was represented by three series of intermittent isometric contraction of the finger flexors until exhaustion with 20 minutes rest period. The rest period was represented by the immersion of forearm into cold water (8řC; 15řC;) as well as by a passive rest. Sturation O2 of saturated hemoglobin (SmO2) was monitored by the spectrometer throughout the entire measurements at flexor digitorum profundus. Results: The reliability of measurements was rel=0,79 with standard deviation SD= 27,3s and standard measurement error SEM= 12,5s. The least effective method of recovery was passive recovery. Decrease in the time between the first, second and third contraction respectively was 35s, 34s respectively. Immersion in 15 ř C water under recovery phase led to improvement in the second contraction by 43s and by 27s in the...

Title: Effect of the load and recovery time on a physiological response in sport rock climbers Objectives: The main purpose of this study was to assess the inluence of various types of climbing loads on a physiological response in sport rock climbers. Methods: Seven experienced (8 to 9+, UIAA - Union Internationale des Associations d'Alpinisme) sport climbers (age 25,4 ± 7 years, body 64,8 ± 6 kg, height 175,8 ± 5,3 cm) were subjected to climbing test until exhaustion, which involved three excercises that included various types of load: continuous, intermittent with 30s load and 30s rest periods (test 30/30) and intermittent with 90s load and 90s rest periods (test 90/90). All subjects refrained from exercising at least 48h between each testing. The monitored variables were performance of climbing steps, heart rate (HR), oxygen consumption (VO2), minute ventilation (VE), energy expenditure (EE) and blood lactate (LA). Results: Peak values of monitored variables show that a climbing intensity was similar among all tests (HRpeak 168 ± 11 to 172 ± 7 bites/min, VO2peak 35,2 ± 4,7 to 40,3 ± 5,3 ml/kg/min, LA 4,1 ± 1,1 to 4,9 ± 1,4 mmol/l). EE was in average 9,0 to 9,8 kcal. Subjects climbed longest (4min 45s ± 37s) in the test 30/30 (six climbers achieved maximum defined time 10 x 30s), whereas total...

Effect of two active recovery methods on repeated bouts of finger flexor isometric performance
Psohlavec, Lukáš ; Baláš, Jiří (advisor) ; Malý, Tomáš (referee)
Title: Effect of two active recovery methods on repeated bout of finger flexors isometric performance. Goals: Compare two methods of active recovery - global and local, during repeated isometric performance and learn the difference between active and passive recovery. Method: Ten recreational athletes in average age 30,4 ± 5,9 years performed in a random cross-over desing 3 sessions with 3 repeated isometric intermittent contraction. The effect of active global recovery, active local recovery and passive recovery between repetions was monitored. Results: More effective type of recovery was active recovery. There was no difference between both active recovery methods. Performed decrease in active global recovery was activleast effective method of recovery was passive recovery. Decrease in the time in active global recovery was 21,7s (29,77%) and in active local recovery 20,8s (30,1%). The least effective was passive recovery. There was decrease 24,6s (35,34%). Key words: recovery, active recovery, local recovery, finger flexors, interrmitent, isometric contraction.

Using the Yo-Yo test in football in the category U 12
Janoušek, Adam ; Frýbort, Pavel (advisor) ; Kokštejn, Jakub (referee)
Title: Using the Yo-Yo test in football in the category U 12 Objectives: Aim of this work is to compare the results of my research with other research, which also used the same type of yo - yo test at ages younger pupils. Methods: Group monitored the players consists of 26 probands in category U 12 who play in the elite team of high level. Players warm up before the test completed. Then it passed to the actual testing, which consisted of 2 x 20 meter runs and was interspersed with short recovery breaks until the player was able to meet the test requirements. For each player after removal from the test are enrolled elapsed distance. Results: The average elapsed distance from my research is 305.23 meters, while the Japanese footballers result is 286.2 meters. From the results it is obvious that the players of the research group achieved better results than the players playing the Japanese league, and despite the fact that they have a lower average age. Key words: football, yo - yo test, recovery, performance, level.

The Developmental Typology of the Fastest Growing Portion of the Metropolitan USA in the Decade from 2000 to 2010
Kohl, Ondřej ; Jeleček, Leoš (advisor) ; Ouředníček, Martin (referee)
This text was written as a diploma thesis of master's degree study course "Regional and political geography." It focuses on the development between the last two censuses, of the fastest growing metropolitan areas in the United States. The economic crisis of the late 2000s has been a major turning point of the decade. The goal of the research was to create a developmental typology of the fastest growing metros. The text analyzes "classifiers" data in order to decide what developmental types have been among the metros. A major factor contributing to high population gains in the fastest growing metros was the migration induced by the housing bubble.

Strejcová, Barbora ; Süss, Vladimír (advisor) ; Pavlů, Dagmar (referee) ; Pyšný, Ladislav (referee)
Title: The effect of active recovery and hydroterapy on the subsequent short-term and medium-term muscular performance Objective: The aim of the study was to compare the effect of two recoveries (ice pack, passive recovery) on the subsequent short-term and three recoveries (active recovery, cold water immersion, passive recovery) on the medium-term knee strength in the extension and flexion. Methods: Fourteen athletes in an average age of 26,6±4,4 years performed, in a random cross-over design, 2 sessions with 5 repeated short-term isokinetic tests and 3 sessions with 3 repeated medium-term isokinetic tests. The effect of ice packs and passive rest and the effect of active recovery, passive rest and cold water immersion were assessed by the 5x2 (time x recovery) and 3x3 (time x recovery) repeated-measure ANOVA, respectively. Results: The ice packs did not have any effect on peak torque, total work and average power during short-term performances. The average heart rate was significantly lower during measurements with the ice packs than during the passive recovery (125±15 vs. 135±20 tepů. min-1 ). We stated significantly lower changes in knee extension for the peak torque after the active recovery (↑ 0,9 N.m) than after the cold water immersion (↓ 14,6 N.m) or the passive recovery (↓ 13,9 N.m).

Niemiec, Iveta ; Bělina, Miroslav (advisor) ; Pichrt, Jan (referee)
Title: Leave Legislation in Czech Republic, Slovakia and Poland Author: Iveta Niemiec Abstract: There are three neighbouring states in the spotlight of this thesis: Czech Republic, Slovakia and Poland. Approach of the annual leave legislation in those countries and mutual comparison could be defined as a main goal. Adumbration of annual leave as a significant part of labour law legislation and its purpose definition, which consists mainly in creating space for recovery and longer rest, is followed by short excursion into the history of legislation development. In this regard the year 1918 is found to be a breakthrough, which opened up the possibility of own legislation in Czechoslovakia and Poland. Getting closer to the leave legislation of particular states is preparation for a comparison of particular institutes and sub-institutes of leave of each labour code. Subsequenlty stated judicature provides an overview of application of legal rules related to the leave. Investigation is concluded by impact of the EU legislation on the particular institutes of the leave. The thesis is finalized by adumbration of inspirational parts of slovak and polish leave legislation. Key words: labour code, leave, recovery, leave entitlement, comparison, inspiration
