Increased levels of clinical significance were seen at the finish line of the Norseman in white blood cells count (WBC) (14.2 109/L, p < 0.001), creatinine kinase (CK) (2450 U/L, p < 0.001) and NT-proBNP (576 ng/L, p < 0.001). Blood samples were collected before, immediately after, and the day following the Norseman Xtreme Triatlon (n = 98) and Oslo Olympic Triathlon (n = 15).
To aid clinicians treating patients and medical teams in such events we have studied common biomarkers after at The Norseman Xtreme Triathlon (Norseman), an Ironman distance triathlon with an accumulated climb of 5200 m, and an Olympic triathlon for comparison. Occasionally, competition athletes need medical assistance and hospitalisation during prolonged exercise events. Prolonged exercise is known to cause changes in common biomarkers.
