Energy expenditure in Zumba
Řehořková, Michaela ; Baláš, Jiří (advisor) ; Bunc, Václav (referee)
The main objective of this study was to assess the energy demand of Zumba. The energy demand was determined by the indirect calorimetry. Four middle-ages women experienced in zumba participated in the study. A walking test untill the individual maximal exhaustion was performed on a treadmill to determine the relationship between heart rate, pulmonary ventilation and oxygen consumption. The energy expenditure of zumba was undertaken during 3 lessons, which took place at intervals of 3-5 days. We found an average oxygen consumption of 25,73 ± 0,95 ml.min-1 .kg-1 , which corresponded to the energy expenditure of 0,55 ± 0,03 kJ.min-1 .kg-1 . Therefore, we consider Zumba as the activity with high energy demand.

The energetic cost of middle aged women during zumba lesson measured by indirect calorimetric method
Řehořková, Michaela ; Strejcová, Barbora (advisor) ; Bunc, Václav (referee)
Title: The energetic cost of middle aged women during zumba lesson measured by indirect calorimetric method Objectives: The aim of this study is to assess energy cost of the middle aged women during zumba exercise. Methods: A group of 6 women (age range 27-37 years) volunteered to participate in this study. To assess the maximal oxygen consumption, we used the running test to individual maximum. Each subject took part in six lessons of zumba in commercial fitness gym. Each subject was measured during 60 min long lesson. Results: The oxygen consumption of the whole zumba exercise was 19,5±2,2 ml.kg-1 .min-1 that is 68,4 % of the maximal oxygen consumption 40,1±7,4 ml.kg-1 .min-1 measured during running test. That exactly means a caloric expenditure 404,8 kcal (or 1692,2 kJ) during one lesson of zumba. The intensity of whole class reported by HR was covered by 67,5 % from HRmax and by Borg's rates of perceived exertion (6-20) with rates 14±2 from 18±2 immediately after the maximal running test. The highest energetic cost (336, 3 kcal, resp. 1405,9 kJ) was during the main part of the lesson. Zumba can be classified as moderately challenging type of exercise, which is good for fat burning; this statement is based on values of the heart rate measured during lessons of zumba. Key words: zumba, energetic...
