title: Individual variability of high-sensitivity cardiac troponin levels after aerobic exercise is not mediated by exercise mode.
abstract: 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.
