In this thesis we compared strain and effort for the role of Ali in a musical Mamma mia. Then we compared strain and effort between the musical and a 10-kilometer run. Two actresses (30 years, 58 kilograms and 32 years, 61 kilograms), who had the part as alternates or substitutes in the musical, participated in the study. After taken measurements, we analysed the duration of the work load, covered distance, average speed of movement, maximum speed of movement, average heart rate by time segments, maximum heart rate, number of steps per minute and calorie consumption.
The performance (character of Ali) in the musical was an interval workload with 10 intervals, which lasted approximately four minutes and were quite intense. The heart rates of the participants were between 150 and 162. Interval breaks varied from three to twenty minutes. When running 10-kilometers there was an even long-term work load, without changes in the intensity and without intermediate breaks. We discovered, that both strain and effort are very different at both activities.
Both activities were similar in terms of energy consumption. In musical, first measured actress burnt 707 kilocalories and the second measured actress 676 kilocalories. At the 10-kilometer run first measured actress burnt 647 kilocalories and the second one 842 kilocalories.
Based on the results, we prepared an example of training for the actress, which would perform in the role of Ali.
