Blood biomarkers in male and female participants after an Ironman-distance triathlon.

Background: While overall physical activity is clearly associated with a better short-term and long-term health, prolonged strenuous physical activity may result in a rise in acute levels of blood-biomarkers used in clinical practice for diagnosis of various conditions or diseases. In this study, we explored the acute effects of a full Ironman-distance triathlon on biomarkers related to heart-, liver-, kidney- and skeletal muscle damage immediately post-race and after one week's rest. We also examined if sex, age, finishing time and body composition influenced the post-race values of the biomarkers.

[Biochemical changes after strenuous exercise – data from the Kalmar Ironman].

Biochemical changes after strenuous exercise - data from the Kalmar Ironman Strenuous and prolonged exercise like marathon, ultra running and triathlon can lead to changes in biomarkers of cardiac, muscle and kidney functional damage. We present the data of 30 (15 men, 15 women) participants of the Kalmar Ironman 2015. Pre-race electrocardiograms and echocardiograms showed a high frequency of abnormalities.
