Olah et al. have recently shown adverse effects of exhaustive exercise on the heart in a murine model. The authors showed elevated plasma levels of cardiac troponin T and creatinine kinase after exhaustive exercise, compared to controls, along with elevated nitro-oxidative stress, myocardium enhanced apoptotic signaling and dysregulation of the matrix metalloproteinase system [1]. In this line, Legaz-Arrese et al. have investigated the influence of a mild endurance training program (14 weeks running, 3–4 days/week, 120–240 min/week, 65–85% of maximum heart rate) on exercise-induced increase of high-sensitivity cardiac troponin T (hs-cTnT) in humans, showing that both baseline and post-exercise hs-cTnT values after training were higher compared with pre-training and the response of the control group (P = 0.008).
