Blažek, Dušan ; Šťastný, Petr (advisor) ; Vágner, Michal (referee) ; Farana, Roman (referee)
Title: The effect of breathing technique on intra-thoracic pressure, kinematics of barbell, and muscle activity during bench press exercise. Objectives: The main aim of this study is to determine relationship between breathing technique and bench press exercise. Furthermore, determine which breathing modification leads to overcoming highest resistance and how each individual breathing techniques (Valsalva maneuver (VM), Hold breath (HB), Lung packing (PAC), "reversed breathing" (REVB)) affects kinematics of barbell, and muscle activity, during different intensity (1 RM, 4RM, 8RM, 12RM). Methods: Experiment of cross-sectional character, with usage of our-calibrated sensor, for intrathoracic pressure measurements, 3D kinematics with passive markers and surface electromyography. For measuring anthropometric measurements was further used goniometer, digital scale, and measuring tape. Comparisons of the breathing techniques was done by analysis of covariance ANOVA, while particular parameters were compared by Pearson correlation. Results: Except of REVB technique, which indicated significantly lower load, there was no significant difference between techniques in lifted resistance. Similar effect was observed at results of intrathoracic pressure, where REVB technique showed significantly lower pressure,...

Gajdoš, Miloslav ; Jandová, Soňa (advisor) ; Janura, Miroslav (referee) ; Šťastný, Petr (referee)
Title: Influence of gait in high heels on posture, and division of pressure on the contact area level of the feet and the floor Objective: The aim of the dissertation was to verify how walking in high-heeled shoes influences the time and pressure parameters of the step cycle and posture during slow and very slow walking in low experienced wearers. Methods: The research study was an empirical, comparative intra-individual study. Pedar-X® measuring inserts (Novel, Munich, Germany) were used to measure the distribution of plantar pressures and to evaluate time parameters while walking on a conveyor belt at v1 = 0.97 ms-1 and v2 = 0.56 ms-1 in straight shoes and high-heeled shoes. SonoSens Monitor Analyzer® (Gefremed, Chemnitz, Germany) was used to assess posture. The research group consisted of thirty healthy women wearing high-heeled shoes occasionally (age: 21.8 ± 2.09 years, weight: 55.7 ± 4.05 kg, height: 1.66 ± 0.03 m). Anova test and paired t-test were used for statistical analysis, and the Cohen coefficient d was used to calculate material significance. Results: Significant differences in time and plantar pressure variables were found when walking in high-heeled shoes compared to straight footwear. For both types of footwear, walking speed only affected time variables, but not dynamic...

The vital capacity of lungs in novice figure skaters
Hrdličková, Kristýna ; Sedláčková, Marie (advisor) ; Šťastný, Petr (referee)
Title: The vital capacity of lungs in novice figure skaters Aims: The main aims of this study were 1. to compare the forced vital capacity (FVC) at rest between young female figure skaters and girls of the same age; 2. to find how the free skate influences respiratory functions in young female figure skaters. Method: A personal spirometer was used to test the 20 young female figure skaters aged 11-14 years in this empirical research. Data from a festival of sport for kids "Sporťáček" were used to compare FVC among young female figure skaters and athletes from several other sports. Data were analyzed using non-parametric statistic methods. Results: Compared to athletes from other sports, FVC of young female figure skaters was significantly lower, the same result was also found after conversion on FVC index (FVC/BMI). The level of selected respiratory measures did not differ significantly immediately after free skate nor a minute after the performance. However, there was an increasing trend found immediately after free skate compared to the level at rest. Conclusions: Specific training loads in the figure skating may negatively influence FVC. FVC as well as some other respiratory measures may slightly increase immediately after performance. Key words: figure skating, spirometry, breathing, older...
