Effect of Training Load on Post-Exercise Cardiac Troponin T Elevations in Young Soccer Players.

Training load (TL) metrics are usually assessed to estimate the individual, physiological and psychological, acute, and adaptive responses to training. Cardiac troponins (cTn) reflect myocardial damage and are routinely analyzed for the clinical diagnosis of myocardial injury. The association between TL and post-exercise cTn elevations is scarcely investigated in young athletes, especially after playing common team sports such as soccer.

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

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.
