Effects of moderate- to high-level physical performance on blood levels of cardiac biomarkers in extreme conditions of Antarctica
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 ev...
