Validity of commercially available smartwatches when estimating energy expenditure
Kopecký, David ; Pokorný, Jan (referee) ; Řehák Kopečková, Barbora (advisor)
Metabolic rate is an energy quantity. Its value is a key input not only in thermophysiological models, but also in the calculation of heat stress indices or complex models predicting a person's thermal sensation. With the dynamic development of technology, sporttesters are able to estimate energy expenditure, among other things. It is a non-invasive method of estimating energy expenditure, or metabolic rate, using associated body functions to predict it. This work deals with the validity of the accuracy of metabolic rate estimation using the Garmin Fenix 6X Pro sporttester in comparison with indirect calorimetry. The accuracy of the metabolic rate estimation was tested for the activities of lying down, administrative work and cycling with regulated mechanical resistance of 100 and 150 W. 15 male subjects aged 28 ± 5 years, with a weight of 83.2 ± 13.5 kg and a height of 180 ± 7 cm participated in the study. In terms of the results, it is possible to observe a lower accuracy of prediction of metabolic rate for low-intensity activities, with the resulting MAPE being around 19-43 %. On the other hand, for activities with moderate activity, the prediction of the metabolic rate by the used sporttester proved to be sufficiently accurate, with a resulting MAPE in the range of 6–8 %.

Verification of metabolism prediction based on performed activity
Kopecký, David ; Pokorný, Jan (referee) ; Kopečková, Barbora (advisor)
Nowadays, metabolic rate or energy expenditure in general is one of the most discussed topics, especially in connection with a healthy lifestyle. Nevertheless, the metabolic rate can be used as a relatively accurate indicator of physical or thermal load as well. Usually, the value of metabolic rate is used as input into various physiological models. These models estimate the body’s thermal stress, for instance when working in a protective suit. The thesis deals not only with tabulated values of metabolic rate, but it also focuses on the accuracy of estimated metabolic rate using simple measuring devices. The Apple Watch Series 4 smartwatch, the Garmin Fenix 6 Pro Glass sports tester, and the Fitbit Inspire smart sports bracelet were used for the measurements published in the thesis. The results of the measurements show that contemporary sports testers are still inappropriate for use in healthcare or elite sports.

The effect of the compensation program on the reduction of muscle imbalances for football players U17 and U19
Kopecký, David ; Hráský, Pavel (advisor) ; Kaplan, Aleš (referee)
Title: The effect of the compensation program on the reduction of muscle imbalances for football players U17 and U19 Objectives: The objective of this study is to design and test the effect of a set of compensatory exercises for U17 and U19 soccer players that will lead to a reduction in muscle imbalances. Methods: The theoretical part used content analysis of documents and other scientific publications discussing muscle imbalances in football players. In the practical part, an entrance diagnosis was performed to detect muscle imbalances. In the practical part of the study 38 players (boys) of the U17 and U19 category of the MFK Chrudim football club were included. Both categories (U17 and U19) were divided into two groups, the intervention group and the control group. The probands were tested with a standardized protocol according to the muscle test according to Janda (2004). The rating scales were also taken from these tests. Furthermore, the testing was completed with tests according to Kolar (2009), focusing on the deep stabilization system (diaphragm test, intra-abdominal pressure test) and joint mobility of the lower limbs in the form of a deep squat test. Other tests used were the Thomayer test, deep- seated forward bending according to the test battery: the Unifittest (6-60), and an...

Case study of physiotherapic care of hemorrhagic stroke patient with right-sided hemiparesis
Kopecký, David ; Reckziegelová, Petra (advisor) ; Vrbický, David (referee)
Author: David Kopecký Title: Case study of physiotherapic care of hemorrhagic stroke patient with right-sided hemiparesis Objectives: The purpose of this thesis was to to summarize the theoretical information on CMP with a focus on the hemorrhagic type and to elaborate a case report of physiotherapeutic care of a patient after hemorrhagic CMP with right-sided hemiparesis hemiparesis Methods: The content of the theoretical part is drawn from professional articles, textbooks and studies. The case study consists of anamnesis, initial kinesiological analysis, short-term and long-term therapeutic plan, 8 therapeutic units, output kinesiological analysis, evaluation of the effect of therapy and final discussion where I compare the effect of my therapy with studies. Results: The most significant changes in the patient's condition include a decrease in the painfulness of the affected shoulder, an increase in the passive range and the onset of active movements. Progress was also noted in gait stereotype and ADL. Conclusion: This thesis contains theoretical background on stroke and in a special section is described a case study of a patient with this disease. The case report was prepared in the ÚVN Prague in the period from 13th January to 26th January under the supervision of Bc. Eva Hankovcova. Keywords:...

Sources of variation in the genus Anthoxanthum L.
Chumová, Zuzana ; Trávníček, Pavel (advisor) ; Mano Loureiro, Joao Carlos (referee) ; Kopecký, David (referee)
The genus Anthoxanthum (sweet vernal grass, Poaceae) represents a taxo- nomically intricate polyploid complex with a large phenotypic variation and still poorly resolved evolutionary relationships. The thesis deals with Anthoxanthum sect. Anthoxanthum in Europe, which comprises five traditionally recognized perennials (A. odoratum, diploid and tetraploid A. alpinum, A. maderense and A. amarum) and three annuals (A. gracile, A. aristatum and A. ovatum). Combination of different methods (DNA flow cytometry, sequencing of nrDNA ITS and two plastid regions, fluorescence and genomic in situ hybridization, climatic niche characterization and spatio-temporal modelling) was used to investigate ploidy and genome size variation of the genus across its European range, and to clarify the species origin and phylogeny of its members. Eight taxonomic groups that predominantly corresponded to traditionally recognized species were delimited on the basis of genome size values and phenotypic variation. While our data supported the merger of A. aristatum and A. ovatum, eastern Mediterranean populations traditionally referred to as diploid A. odoratum were shown to be cytologically distinct and may represent a new taxon. Genuine intraspecific variation in genome size was detected within the genus and the evidence for...

Development of movement preconditions focusing on children of younger school age in football.
Kopecký, David ; Bunc, Václav (advisor) ; Buzek, Mario (referee)
Title: Development of movement preconditions focusing on children of younger school age in football. Objectives: Designing adequate exercises for the development of movement skills for players in youth categories in football. Methods: In this thesis was used analysis of documents and other professional publications related to children's sports training in young age. The thesis focuses on children of younger school age especially on children aged 6 to 12. I was based on literature that deals with the approach in youth training, the collected data were used in creating a stack of exercises and recommendations for youth training. Literature was selected by key words: children, football, youth, development, training. I searched the literature using a database Sportdiscus a PubMed. Results: The result is a stack of exercises for the development of individual movement prerequisites and recommendations that summarizes, what the coach has to know if she/he wants to conduct training designed for the category from U7 to category U12. Furthermore, the recommendation describes how to develop individual movement preconditions in training. Key words: children, football, youth, development, training
