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. The objective of this study was to assess the relationship
between TL measurements during a small-sided soccer game and the subsequent increase in cTn in
young players. Twenty male soccer players (age 11.9 ± 2 years, height 151 ± 13 cm, weight 43 ± 13 kg)
were monitored during a 5 × 5 small-sided game and had blood samples drawn before, immediately
after, and 3 h after exercise for a posterior analysis of high-sensitivity cardiac troponin T (hs-cTnT).
Internal, external, and mixed metrics of TL were obtained from the rating of perceived exertion (RPE),
heart rate (HR), and GPS player tracking. The results show that the concentration of hs-cTnT peaked
at 3 h post-exercise in all participants. The magnitude of hs-cTnT elevation was mainly explained by
the exercise duration in the maximal heart rate zone (Maximum Probability of Effect (MPE) = 92.5%),
time in the high-speed zone (MPE = 90.4 %), and distance in the high-speed zone (MPE = 90.45%).
Our results support the idea that common metrics of TL in soccer, easily obtained using player
tracking systems, are strongly associated with the release of hs-cTnT in children and adolescents.
