Experimental models of increased physical activity for cardiovascular research
Ševčíková, Anežka ; Kolář, František (advisor) ; Kašík, Petr (referee)
This thesis provides a critical review of experimental models and protocols of increased physical activity that have been used for various purposes in cardiovascular research in small laboratory rodents. The thesis describes their physiological and pathophysiological effects and evaluates the advantages and disadvantages of using each model to study the adaptive mechanisms and beneficial effects of physical activity on cardiovascular disease. The use of physical activity in cardiovascular patients or people with cardiovascular risk factors is also mentioned. A review of exercise stress tests used to detect the degree of experimental heart failure of various etiologies and specific examples are also included. Key words physical activity, endurance training, stress test, small laboratory animals, heart, hypertrophy, therapeutic effects

The Verification of the Use of the Heart Rate Variability in the Management of Training Process in Adolescent Mountain Bikers
KADLEC, Jakub
Cross-country Olympic (XCO) is one of the endurance sports. The training process of mountain bikers is very demanding because the rider must be complex in endurance and anaerobic skills. Alfa and omega of the training process is a periodization of training load and recovery. Heart rate variability (HRV) can help us assess body's condition and readiness for training. In the practical part of the work, an experiment was carried out, which was attended by eight adolescent mountain bikers. The intervention took place during the training camp. The total intervention time was four weeks. The participants were randomized into two groups. The first experimental group (ES) (n = 4) was a graduated training camp with a heart rate variability guided training load. The second group was a control group that used a classical predefined training plan. For evaluation of HRV training efficiency a VO2max test and 20 minutes time trial (20TT) on an ergometer were used. The results showed an improvement in mean power output during 20TT in the experimental group (PRE 303.5 W; POST 317.5 W) and relative values (PRE 4.58 W.kg-1; POST 4.68 W.kg-1). On the other hand, there were no changes in average power (PRE 308 W; POST 305.7 W) and relative values (PRE 4.20 W.kg-1; POST 4.20 W.kg-1). From a statistical point of view, there was no effect of HRV training on performance indicators (p <0.05). Our experiment failed to confirm the usefulness of HRV training for cyclists.

Use of CrossFit elements to develop the strength and endurance abilities of the general population.
Vácha, Marek ; Bunc, Václav (advisor) ; Vindušková, Jitka (referee)
Title of the thesis: Use of CrossFit elements to develop the strength and endurance abilities of the general population. Objectives of the thesis: Based on literary research and own experience, prepare a design of an interventional movement program with CrossFit elements aimed at affecting the strength and endurance abilities of a group of men from the general population. Methods: The research method of professional literature was used in this thesis, especially collection, sorting and evaluation of relevant information. In proces of searching for information, I drew from professional books, scientific articles, studies or websites dealing with the researched topic. I searched for electronic publications on the following servers: Web of Science, Scholar Google, SportDiscus, PubMed. Results: Based on information from the professional literature, I have come to believe that CrossFit training has the potential to develop both strength and endurance abilities, as well as aerobic fitness or change body composition. The result of the thesis is a theoretical design of a seven-week interventional movement program with CrossFit elements, which is aimed at developing strength and endurance abilities. It is intended for a group of adult males from the general population in the age range of 21-30 years....

Effect of the eight-week intervention training program with the CrossFit system on physical fitness
Crkalová, Monika ; Bunc, Václav (advisor) ; Jebavý, Radim (referee)
Title: Effect of the eight-week intervention training program with the CrossFit system on physical fitness Objective: The aim of the thesis is to examine the influence of an individual intervention CrossFit training program on the development of strength and endurance in a semi-professional, systematically training 21 years old athlete. Methods: The thesis has the characteristics of case study. We firstly carried out a research and followed with an intervention. The theoretical part consists of the research, i.e., the information about fitness and physical condition, CrossFit, strength and endurance training, diagnostics, the effects of the training, periodization of the training and regeneration. The practical part consists of the casuistic of the proband, who went through an 8-week training program. In order to determine the importance of the tests, we had to establish their error rate. To do so, we added up the error rate of the method, that is 1%, and the biological error rate, that is 2%. Thus, the final error rate is 3% of the initial value. We can consider the improvement in the test significant if it is greater than 3%. To evaluate, we applied the methods of analysis and comparison of the first week's results with the final week's results. Results: We observed an improvement in both...

Effects of minimal dose of resistance training on body composition and running performance in female recreational runners
Štohanzl, Michal ; Bunc, Václav (advisor) ; Kučera, Vladimír (referee) ; Kampmiller, Tomáš (referee)
Title: Effects of minimal dose of resistance training on body composition and running performance in female recreational runners Objective: The purpose of this study was to analyse the extent to which minimal dose resistance training would elicit improvements in running performance and body composition for female recreational runners. Methods: Forty-one female recreational runners were randomly assigned to one of three groups (endurance running [V] n=14; combined endurance running and resistance training program once [VR30] n=14 and twice a week [VR60] n=13, respectively). During the 10-week training program, the V group completed 3 hours of continuous endurance running per week; VR30 completed 2 ½ hours of continuous endurance running and 1 x 30 min of resistance training per week, while VR60 group completed 2 hours of continuous endurance running and 2x30 min of resistance training per week. Body composition (FM, FFM, ECM/BCM), standing long jump, running economy, ventilatory anaerobic threshold and maximal endurance performance characteristics were assessed using ANOVA with repeated measures. Body composition was assessed via whole-body bio impedance. Performance parameters were determined during running on a treadmill. Results: Thirty-one female recreational runners completed 10-week...

Endurance Training Individualization in Marathon Preparation
Kadeřábek, Bronislav ; Bunc, Václav (advisor) ; Horčic, Josef (referee)
SUMMARY: Title: Endurance Training Individualization in Marathon Preparation Aim: To compile, compare and summarize present knowledge of endurance training; to apply the gained knowledge to marathon distance; to inform about procedures which can be used to individualize, analyze and lead endurance training to reach the highest possible effectiveness; to confirm the validity of theoretical knowledge in practice; to achieve the required performance in a race. Methods: Literature research based on study of available documents; gathering findings from public experts, articles, publications, written and digital resources; laboratory measurements aimed at finding the initial level, creating individual training programme and carrying out continuous assessment. Results: The thesis results in creating individual training programme to achieve the time 3:30:00 in the first city marathon. Partial results of the thesis have the form of protocols from continuous tests carried out in the Laboratory of Sport Motor Activity at Faculty of Physical Education and Sport and a training diary. The main result is to achieve the time 3:29:48 in the race. Key words: endurance training, marathon, training management, development, individualization
