Description
Martin Bonnevie-Svendsen and co-authors present a 2026 study of heart stress markers in extreme triathletes. Troponins, proteins that leak from heart muscle, are the standard test when doctors suspect heart disease. Yet hard exercise also raises them, and recent work hints the rise may itself predict future disease.
The team sampled 93 finishers of the Norseman Xtreme Triathlon before the race, within an hour after, and again the next day. Both troponin I and troponin T jumped sharply after the race and stayed high a day later. Their ratio spiked at the finish, then fell below baseline by the next day. Three athletes stood out with very high troponin I. The patterns may help separate harmless exercise effects from true heart trouble.
