Panská, Šárka ; Jelen, Karel (advisor) ; Pokorný, Jan (referee) ; Radvanský, Jiří (referee)
Title: Influence of Hyperkinetic Load on Selected Mechanical Changes of Human Axial System. Objectives: The main aim of this thesis is to determine the influence of hyperkinetic load on the change of selected mechanical properties of the rhythmic gymnastic axial system based on the sophisticated use of the Transfer Vibration through Spine (TVS) method. Methods: The following experimental methods were used to identify changes in rheological properties of AS and to assess load intensity: 1) TVS method; 2) software for evaluating and analyzing vibration tests of heterogeneous systems; 3) kinematic and dynamic motion analysis using:  2D motion video recording,  QUALISYS 3D motion analysis system,  KISTLER, to analyze dynamic human-surroundings interactions. Results: Pilot studies and the main experimental part of the thesis have shown that the use of the TVS method can identify both short-term and longitudinal changes of AS mechanical properties. Due to the hyperkinetic load, the selected mechanical properties of the rhythmic AS are changed. The gymnastic apparatus reacts to the training load by reducing the rheological parameters, especially the damping coefficient b and the viscosity µ. After regeneration, which is on the following day, the parameters return to the default values. The impact load...

Title: Effect of cold water immersion on intermittent isometric forearm flexor contractions to failure in rock climbers Objectives: The aim of this study was to determine the effect of cold water immersion on intermittent isometric forearm flexor contraction to failure in rock climbers. Methods: Thirty-two climbers (15 male and 17 female) completed three intermittent trials to failure, on a climbing-specific handgrip dynamometer, on three separate visits to the laboratory. For each visit a different recovery strategy was employed: passive recovery (PAS), cold water immersion at 8 řC (CWI 8) or 15 řC (CWI 15). The force time integral (FTI - time of contraction multiplied by the force of contraction) was determined to assess intermittent performance. The tissue saturation index (TSI) and total haemoglobin (tHb) during isometric contractions from near-infrared spectroscopy (NIRS) were determined to assess hemodynamic changes. Differences between repeated trials and three recovery protocols, derived parameters NIRS, were assessed using repeated measures ANOVA with Bonferroni corrections. Results: There was no significant difference between conditions after trial one. In response to the PAS recovery condition there was a 10% and 22% decrease in FTI in the second and third trials, respectively. The PAS...
Integration of walking intervention combining activity monitor and online application into preventive care in general practice: pilot randomised controlled study
Větrovský, Tomáš ; Bunc, Václav (advisor) ; Sigmund, Erik (referee) ; Radvanský, Jiří (referee)
4 Abstract Background: Insufficient physical activity is one of the leading modifiable risk factors responsible for numerous chronic diseases and for premature death. Walking can be considered as the most natural form of physical activity and can be easily incorporated into many activities of daily living. Interventions aimed at promoting walking could substantially contribute towards increasing physical activity levels of the most sedentary individuals; within these interventions, pedometers are commonly used as effective motivational instruments to increase walking in healthy adults and across a range clinical conditions. Additional counseling provided in regular intervals throughout the intervention period can positively influence patients' adherence and help patients overcome certain psychological or lifestyle barriers, ultimately increasing physical activity. Objectives: The main objectives are: (1) To evaluate the feasibility of a pedometer-based walking intervention supplemented with a counseling component in a pilot randomized controlled trial. (2) To assess the preliminary efficacy of the intervention on PA levels and health-related outcomes, including measures of mental health and health-related quality of life. (3) To qualitatively explore the views of patients participating in the intervention....

Bibliographic identification: ULRICHOVÁ, Michaela. Kineziotherapy And Postural Changes At Very Young Patients With Anorexia Nervosa. Prague: Charles University. 2nd Faculty of Medicine. Department of Rehabilitation and Sports Medicine, 2017. 82 p. Supervisor doc. MUDr. Jiří Radvanský, CSc. Author's first name and surname: Michaela Ulrichová Title of the diploma thesis: Kineziotherapy And Postural Changes At Very Young Patients With Anorexia Nervosa Department: Department of physiotherapy Supervisor: Doc. MUDr. Jiří Radvanský CSc. The year of presentation: 2017 Abstract: There is a number of studies demonstrating the positive effects of supervised exercise therapy on patients with anorexia nervosa. Recent literature suggests that an appropriate physical activity may improve the quality of life during inpatient treatment, increase weekly weight gain, reduce eating pathology and lower relapse rates. The objective of this diploma thesis was to design an exercise program for hospitalised child patients with anorexia nervosa. A sample of 25 female patients was used to prove that this program has no adverse effect on the re-feeding program. The initial kineziological analysis of those patients showed significant patological postural changes which are much more frequent for patients with anorexia nervosa than for...
Assessment of influence of physiotherapy on cardiopulmonary system in children with congenital heart defect
Kopecká, Anežka ; Radvanský, Jiří (advisor) ; Tetřevová, Lenka (referee)
The aim of the study was to compose and realize physiotherapeutic program for children with congenital heart disease to improve their postural-respirational function and to assess the influence of this program on cardiopulmonary functions of the patients. Our group had five patients with mean age of 15,6 years. Each of them underwent initial examination of the motor system, spirometry and spiroergometric exercise test. Physiotherapeutic program consisted of 8 individual therapies and home-based exercise. Therapy was composed from manual techniques, exercise according to Dynamic neuromuscular stabilisation concept and exercise with inspiratory trainer and improvised PEP system. The final examination was performed in the same manner as the initial one. We compared the results of both examinations, but we found no significant improvement after the physiotherapeutic program.
Blood pressure response to dynamic exercise in young healthy adults
Klabanová, Anežka ; Procházka, Michal (advisor) ; Radvanský, Jiří (referee)
Aim: The aim of this study is to observe and describe blood pressure response (BP) to dynamic exercise during the clinical exercise testing on a cycle ergometr in young healthy adults. Methods: Forty subjects (18 men and 22 women) aged 20-29 years took part in this study. All of them completed the laboratory combined maximal exercise testing. The initial workload of 1 W/kg body weight was followed by the next stages with 0,5 W/kg workload increase every 3 minutes. There was the ramp continuous workload increase at the last stage up to a maximum. Blood pressure was monitored by the auscultatory non- automted mercury-free sphygmomanometer, cardiac activity and heart rate were monitored by ECG. Results: Single average rises of systolic blood pressure (SBP) are lower with every workload increase of 0,5 W/kg. In the group of subjects, that completed the highest workload stage (3 W/kg) before continuing the "ramping-up" phase up to maximum, this trend was most obvious. The average rise of SBP does not exceed 30 mm Hg at workload increase of 1 W/kg. The average SBP at the maximum was 199 ± 13,5 mm Hg for men and 186 ± 10,9 mm Hg for women. Maximum SBP does not correlate with the maximum workload according to our results. Exercise SBP is lower in women than in men at all exercise stages. Conclusion: Our...
Physical Activity and Nutrition in Therapy of Metabolic Syndrome
Joachimová, Marie ; Radvanský, Jiří (advisor) ; Illinger, Vojtěch (referee)
INTRODUCTION: Metabolic syndrome is a cluster of risk factors which tend to occur together and belong to the main causes of cardiovascular disease and type 2 diabetes mellitus. In the treatment of metabolic syndrome dominates pharmacotherapy of the individual components. However, this therapy usually addresses the consequences rather than the causes and puts the patient in the position of a passive recipient of drugs. Although a change of lifestyle should be the cornerstone of prevention and treatment of the metabolic syndrome, the vast majority of the general and professional public doesn't know how and to what extent it can help. OBJECTIVES: The aim of this study was to find recommendations on physical activity and nutrition in relation to the prevention and treatment of metabolic syndrome and the mechanisms of action. METHODS: Information was sought in scientific journals, books and websites of healthcare organizations. Review articles and meta-analysis were selected primarily from the journals, general information and recommendations related to the issues discussed were obtained from the books and websites. RESULTS: The available literature confirmed that the modification of physical activity and nutrition can significantly improve all of the metabolic abnormalities associated with metabolic...

Stráníková, Kateřina ; Radvanský, Jiří (advisor) ; Kříž, Jan (referee)
Introduction - This thesis focuses on the reaction of cardiovascular system to Lokomat therapy in patients with lesion of the spinal cord. It observes reaction of the heart rate and systolic blood pressure and compares with the cardiovascular response to the exercise on an upper body ergometer. Methods - We recruited 25 patients with spinal cord lesion under Th 5 and 4 patients with lesion above Th 5. The blood pressure was measured. The heart rate was measured by by ambulatory blood pressure monitor and an auscultatory method using a mercury manometer and a stethoscope a sporttester. Patients were measured during the Locomat therapy and the exercise on an upper body ergometer during the 6-minute arm test. Results - The parameters of systolic blood pressure and heart rate had a tendency to increase with the peak in 25th minute of the therapy. There was no significant difference between the patients with lesion under or above Th5. The parameters of heart rate were significantly higher on the upper body ergometer than on Lokomat. Conclusion - The Lokomat therapy does have a positive influence to cardiovascular system of patients with complete or incomplete spinal cord injury. When using this approach, the most important benefit is the possibility to activate all parts of body. Keywords: spinal cord injury,...
