Hána, Petr ; Vostatková, Pavlína (advisor) ; Baláš, Jiří (referee)
Title: Comparison of the physical fitness of an 18-year-old population with the results of an international biology program Objectives: The aim of the work is to compare the physical fitness of the current 18-year-old male population based on VO2max results with data measured within the framework of the International Biological Program (IPB) in the 1960s and 1970s in the former Czechoslovak Socialist Republic. Methods: Comparison of the results of two studies. Results: The data obtained from the study carried out in 2023 and the subsequent comparison with the results of the study from 1970 in the framework of the comparison of values of maximum oxygen consumption per kg of weight (VO2max) testify to a significant decrease in the general physical fitness of the 18-year-old male population. Keywords: International Biology Program, 18-year-old male population, maximal oxygen consumption

Function of systemic right ventricle after atrial correction of transposition of great arteries - longitudinal follow-up and impact on exercise capacity Abstract Maximal oxygen uptake during cardiopulmonary exercise test determines decision about pregnancy, therapeutic measures and timing of surgery and heart transplantation. Atrial correction of transposition of great arteries places right ventricle in the systemic positon. The aim of our work was to assess relation of parameters of function of systemic right ventricle to maximal oxygen uptake. 86 patients after Senning correction were subjected to testing of NYHA class, blood tests of NT-proBNP, Holter monitoring and cardiopulmonary exercise test. Systolic function of right ventricle was assessed semiquantitatively by echocardiography and precisely calculated by heart MRI. Maximal oxygen uptake was not associated with NYHA, NT-proBNP nor systolic function of systemic right and subpulmonary left ventricles. The only parameter associated with VO2max was heart rate reserve. Systolic function of the systemic right ventricle is likely only one integral part of a more complex haemodynamic mechanism of total heart output and its increase during exercise. In the second part of our study we aimed to ascertain long term mortality of all patients after atrial...

Cardiorespiratory and hemodynamic response during incremental climbing test in elite sport climbers
Zaťková, Alžbeta ; Baláš, Jiří (advisor) ; Kodejška, Jan (referee)
Title: Cardiorespiratory and hemodynamic response during incremental climbing test in elite sport climbers. Objectives: The aim of this work is to compare cardiorespiratory and hemodynamic response during incremental climbing test between boulderers and lead climbers. Methods: Five men underwent testing on a climbing ergometer with a submaximal climbing load (6m / min) and an incremental climbing test for the maximum. The cardiorespiratory response was assessed using a metabolic analyzer and tissue saturation of the flexor digitorum profundus by near-infrared spectroscopy. Furthermore, climbers underwent an incremental stress test on a running carpet. Results: Climbers with both lead and bouldering reached on climbing ergometer an average of 95 ± 3% of the maximum heart rate measured on the running ergometer. V'O2 ml·min-1 ·kg-1 had lead climbers slightly lower too on the running ergometer, (81 ± 8%, boulders 89.5 ± 0.5), but at the same time they reached a higher inclination (121, 7 ± 4.7 versus 117.5 ± 2.5) and longer duration (462 ± 73, boulder 443.37). We found the difference in the TSI values, too, but it was not larger than 7.2 for which I did not consider these values to be relevant. Conclusions: Deoxygenation and reoxygenation process showed minimal difference between lead climbers and...

Title Analysis of the endurance indicators in selected tests in relation to continuous and intermittent loading Objectives The aim of this study was to examine the accuracy of the prediction formulas for indirect estimation VO2max from performances in the field tests. The criterion for comparing estimated values were results from laboratory spiroergometry test. Methods Ten physically active males (24,5 ± 2,5 years, 179,5 ± 6,2 cm, 75,8 ± 4,9 kg, BMI 23,5 ± 1,3 kg/m2 ) performed four different test sessions. Laboratory treadmill test was used for the direct measurement of the maximal oxygen consumption (VO2max) and three field tests for indirect estimation of the VO2max (Cooper test, Yo-Yo Intermittent Recovery Test Level 1 and 2). All the performances from field tests were calculated using prediction formulas. Results Directly measured values of VO2max during laboratory testing were in average 58,24 ± 2,77 ml.kg-1 .min-1 . Indirectly estimated values of VO2max from performances in the Cooper test were in average 61,15 ± 3,73 ml.kg-1 .min-1 , in Yo-Yo IRT1 52,46 ± 2,51 ml.kg-1 .min-1 and in Yo-Yo IRT2 53,19 ± 1,56 ml.kg-1 .min-1 . There was found large positive correlation between laboratory testing and Cooper test (r = 0,76). This correlation was the only one statistically significant. The...

The relationship between rest and the maximum spirometric indicators in the triathlon
Kučera, Zdeněk ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Title: The relationship between rest and the maximum spirometric indicators in the triathlon Made by: Bc. Zdeněk Kučera Supervisor: Mgr. Lenka Kovářová, Ph.D., MBA Objectives: The aim of thesis is to analyze the relationship between rest and the maximum spirometric indicators for triathletes, who are members of the SCM. It will be also determined whether the analyzed indicators show statistically significantly better performance of triathletes in the representation compared to other triathletes in the SCM. Methods: Data were collected on basis of standard test, which was attended by triathletes in term of SCM. Data were statistically analyzed based on correlation analysis and unpaired non-parametric test. Statistical significance was assessed at the level of 0.05 or 0.01. Results: In the group of men can be confirmed that between rest and maximum indicators is statistically significant correlation relationship (except for respiratory rate and the economy). Another output is achieved for women, a statistically significant relationship exists mainly between rest spirometric indicators and tidal volume and respiratory rate. Higher values of VO2max is achieved in groups with better performance, this is valid for both group of men and women. Keywords: diagnostics, maximum oxygen consumption, vital...
