Influence of postural stability changes on respiratory muscle strenght
Dařinová, Jitka ; Bitnar, Petr (advisor) ; Čakrt, Ondřej (referee)
The presented thesis is focused on the influence of postural stability changes on respiratory muscle strength. The aim of this thesis was to determinate whether the respiratory muscle strength will change during the increased demands on postural stability, and if so, then how exactly. The theoretical part summarized the findings about the diaphragm and its postural stabilizing function, about the connection between breathing and postural control as well as about the influence of body position on respiratory muscle strength. In the practical part of the thesis, the values of the maximal respiratory mouth pressures were measured (PI max and PE max) on 21 healthy subjects ranging from 20 to 26 years of age using the spirometer in three postural situations - standing, standing on the balance surface and standing on the balance surface with no visual control. Throughout the whole group, there were no significant statistical differences ( p ≥ 0,05 ) in the outcome values of the measured postural situations. Two trends were observed in the changes of values of PI max and PE max. During the increased demands for postural stability the value of PI max was higher for 29% and lower for 71% of the measured individuals. The value of PE max was higher for 33% and lower for 67% of the measured individuals. This...

Objective: The goal of the thesis "Monitoring of the Respiratory Functions in patients after the Rib Cage Surgery according to Nuss" was to confront the present knowledge about respiratory functions and the strength of respiratory muscles of patients with inherited pectoral deformity pectus excavatum, to compare it with my own measuring and to find out about their development after the surgical correction according to Nuss. Methodology: There were 15 patients being monitored (13 men and 3 women), who underwent spirometric and bodypletysmographic examination and the occlusal mouth pressures were determined before the surgery. The same pulmonary function tests were run in the course of 4 to 10 months (7.1 months on average) on all the patients, the control determination of mouth pressures is available for 13 of them. Results: In the entry tests, compared to adequate values the patients in this file had increased residual lung capacities (RV 142%, p=0.001; ITGV 116.2%, p=0.004; RV%TLC 133.8%, p=0.002; ITGV% 116.1%, p=0.001) at the expense of statistically lower vital lung capacity (VC 81.9%, p=0.0004) and inspiratory reserve capacity (IC 84.2%, p=0.0003), while the total lung capacity remained unaltered (TLC 99.7%, p=0.877). The obstructive parameters of these patients were significantly altered (FEV1 95.7%,...
