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. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.849 2019 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 32 / 170 = 0.188 2019 Q1 T1 ENVIRONMENTAL SCIENCES 105 / 265 = 0.396 2019 Q2 T2 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 58 / 193 = 0.301 2019 Q2 T1 0.739 2019 Health, Toxicology and Mutagenesis 2019 Q2 Public Health, Environmental and Occupational Health 2019 Q2 Pollution 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-2644-9386 Legaz-Arrese, A.
