Kozel, Jakub ; Jelen, Karel (advisor) ; Heller, Jan (referee)
Title: Biomechanical reflection of the cervicocranial part during frontal impact Objectives: The aim of the work was to analyze in which parameters differs ATD from human participant during frontal impact. Characterize the head movement, compare maximal post impact head speed between ATD and human volunteers and defereneces between volunteer with eye control and without. Methods: Measuring was done with 8 volunteers and ATD (Manikin, 50th percentile man). For each volunteer were done two measurements, first without eye control and second with eye control. ATD was measured twice. It was recorded by Qualisys system, specifically by three optical cameras, on crash simulator. Results were processed in Qualisys Track Manager. There were tracked three markers, two on the body - forehead, shoulder and one on the sledge. Results: Results showed that speed of the head depends on eye control. Volunteer without eye control had higher post impact speed of head (4,94 m/s) than ATD (3,67 m/s) and volunteer with eye contact (3,19 m/s). Quite the same result was observed in change of distance between head and sledge after impact. There was higher value for volunteer without eye contact than for ATD. Keywords: Whiplash, frontal impact, Qualisys, crash simulator, cervicocranial part

Title: Physical profile of judo athletes and its changes due to body weight reduction Aim of work: The aim of this study was to determine the effect of intensive pre-competitive body weight reduction on body composition, anthropometric parameters, postural stability, reaction time, maximal isometric muscle strength and biochemical parameters in the blood of elite judo athletes. Methods: The work compares the results of laboratory testing at the beginning and at the end of body weight reduction. Nine male judo athletes (age 22.3 ± 2.4 years) from the Czech national team participated in the research. For laboratory testing we used bioelectrical impedance analyser InBody 720, anthropometric equipment, pressure plate FootScan, dynamometer and apparatus for measuring reaction times of Biomedical laboratory UK FTVS and equipment for the collection of capillary and venous blood. We created a survey to gather more information about pre-competitive weight loss, attended by 53 competitors (37 men and 16 women, mean age 23.7 ± 3.2 years) who practise judo, wrestling Greco-Roman and freestyle, boxing, kickboxing, thaibox, taekwondo or karate. Results: We found a statistically significant (p<0.01) reduction of body weight, average weight loss was 4.6 % (on average 3.4 ± 1.6 kg). This reduction was reflected in...

Exposure of children to atmospheric aerosol in school gyms
Šafránek, Jiří ; Braniš, Martin (advisor) ; Holcátová, Ivana (referee) ; Heller, Jan (referee)
Research into indoor environment has shown that schools are buildings with high- levels of particulate matter concentrations. This is especially the case of schools situated in high-density traffic or in industrial areas. Several studies have also proven the impact of PM on the teenage generation's health. So far no detailed study has been performed to cover the environment of school gyms where the PM dynamics are different from other indoor microenvironments. This different dynamics relates to the gym environment heterogeneity and to the human activities taking place in it. Due to higher pulmonary ventilation, the exposure of the exercising pupils can reach levels possibly noxious to their health. Size resolved mass concentrations of aerosol were measured in three elementary Schools in Prague. One school was situated in the city centre with high traffic density. The second school was situated on a plateau on the periphery with a medium level traffic. The third school can be found in Prague south-western suburbia, in an open landscape, with low traffic density. PM concentrations were measured simultaneously in naturally ventilated gyms and outdoors ajacent to the particular school building. Two pairs of monitors were used throughout the study: A DustTrak Aerosol Monitor and a Personal Cascade...
