Abstract
The aim of this study was to examine the effect of extreme climatic conditions (particularly cold) on levels of cardiac biomarkers after moderate- to high-level physical performance in members of the 6th and 7th Czech Antarctic Scientific Expeditions during their field work in Antarctica. A study evaluating performance-related changes in levels of cardiac biomarkers in extreme conditions of Antarctica. A total of 35 venous blood samples were collected and analyzed from 17 subjects. The first series of blood samples were collected prior to physical performance, the second 8 to 12 hours post-exercise. The third series of samples were collected only in those subjects where pathological values were detected previously. In 1 subject (12.5%), an increase in NT-proBNP level lasting 24 hours was present after physical performance. Interestingly, none of the individuals had a rise in TnT and DD blood levels following physical exertion. We didn’t find changes in TnT and DD blood levels comparable with changes reported in athletes after a marathon. In only one subject, transitional elevation od NT-proBNP was present. This finding might be due to protective effects of cold on cardiac cells. The effects of physical performance and of work in polar regions should be better investigated in future studies.
