Nutrition of astronauts
Žabová, Anna ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
This non-experimental diploma thesis is focused on nutrition in space and all aspects associated with it. The first part deals with human physiology in microgravity. These are changes affecting the musculoskeletal, cardiovascular, digestive, immune and central nervous systems, but also the consequences of long-term isolation, confined space and cosmic radiation in terms of the nutritional profile of space mission participants. The second part describes the spacefood system and maps the Soviet (later Russian) and American past, present and future in terms of the development of space nutrition and food. The third part focuses on the functioning of space medicine and dietetics, together with interesting projects and programs that have helped or continue to help improve space food systems. Thanks to these programs, the future settlement of the universe will become more realistic. keywords: nutrition, nutrition in space, spacefood, cosmonaut, astronaut, space

The practical part is divided into two researches. The first research is carried out in the form of a quantitative questionnaire, in which the respondents provide information on dietary habits and their presence in the weight category. The second research focuses on five light-weight rowers, whose body composition information is compared in the non-competitive and competitive period. The questionnaire has been filled in by 103 competitors from 9 different sports with weight categories. Some outputs are quite worrying, or even alarming. Only less than one third of the respondents races in their category without major weight fluctuations or greater dietary restrictions. Comparing the data from both measurements of the body composition of the athlete (out of season and before the race) turned out as expected with only...
