Key result
Repeated sprint training significantly increased cardiac troponin T levels compared to moderate intensity continuous training, with 5 of 13 participants exceeding the clinical limit of normal.

p-value: p=<0.01
Short-duration repeated sprint training can induce physiological elevations in cardiac troponin T and CK in healthy young males without impairing cardiac function, which should be recognized to avoid false-positive diagnoses of myocardial injury.
Weippert et al. (2016) conducted an RCT in Healthy (n=13). Repeated sprint training (RST) vs. Moderate intensity continuous training (MCT, 60 minutes at 70% HRpeak) was evaluated on Cardiac troponin T (cTnT) release (p=<0.01). Repeated sprint training significantly increased cardiac troponin T levels compared to moderate intensity continuous training, with 5 of 13 participants exceeding the clinical limit of normal.
