Comparison of methods of basal metabolism determination
Kosková, Martina ; Coufalová, Klára (advisor) ; Hráský, Pavel (referee)
Title: Comparison of individual methods of basal metabolism determination Objectives: The aim of the work is to compare the individual methods of basal metabolism. These values were measured by indirect calorimetry, plethysmography, bioelectric impedance and predictive equations. Methods: The research was attended by 31 people, including eight men and twenty-three women. All participants of my research were aged 21-30 years. None of the participants was a professional athlete, they were all healthy and none of the women were pregnant or had menstruation. The indirect calorimetry, bioelectronics impedance device Tanita MC - 980 and BOD POD were used to collect the data. Basal metabolic rates were calculated from the prediction equations by Harris & Benedict, Fleisch's equation and Schofield's equation using measured anthropometric values. Results: The results of the methods that have been used for this group of people vary, but the difference is not significant. If we choose as a reference method indirect calorimetry, we can't replace it by any other method. The results for other methods are not significantly different, so we can replace one method with another, except indirect calorimetry. From calculations, we also found out that fat free mass greatly influences the results of basal metabolic rate...
