Key result
Sixty minutes of high-intensity swimming, cycling, and running resulted in similar peak hs-cTnT levels among well-trained triathletes, with no significant difference between exercise modes.
Why the study?
Does the mode of aerobic exercise (swimming, cycling, running) affect the magnitude and kinetics of high-sensitivity cardiac troponin T release in healthy triathletes?

p-value: p=0.503
High-sensitivity troponin T elevations are common and similar across different modes of intense aerobic exercise, representing a transient physiological response rather than pathology.
Troponin rises after intense aerobic exercise appear mode-independent in athletes; leaves open mechanisms and relevance beyond triathletes.
We compared the response of high-sensitivity cardiac troponin T (hs-cTnT) after 60 min of swimming, running and cycling in well-trained triathletes. The maximal increase in hs-cTnT was similar in all exercise bouts (swimming 453%, cycling 349% and running 471%) although there was substantial individual variability in peak hs-cTnT. The post-exercise kinetics for hs-cTnT was consistent. The change in hs-cTnT was correlated between trials. In all trials, hs-cTnT had largely returned to baseline levels 24 h post-exercise. In summary, an increase in hs-cTnT was apparent in all triathletes independent of exercise mode and despite variable peak data the consistent kinetics over 24 h post-exercise would suggest this represents a physiological phenomenon.
