M.Reverter-Masia, J.Munguía-Izquierdo, D.Cardiac troponin i release after a basketball match in elite, amateur and junior playersART-2016-93432Background: Available scientific data related to cardiac troponin I (cTnI) release after intermittent exercise is limited. It is also of interest to determine what personal or environmental factors mediate the exercise-induced release of cTnI. This study had two objectives: 1) to examine the individual release of cTnI to a basketball match; and 2) to establish the influence of athlete status as well as biological age on cTnI release. Methods: Thirty-six basketball players (12 adult elite PBA]: 27.3±4.1 years, 12 adult amateur ABA]: 29.6±2.9 years, and 12 junior elite JBA]: 16.6±0.9 years) participated in a simulated basketball match with serial assessment of cTnI at rest, immediately post-and at 1, 3, 6, 12, and 24 h post-exercise. Results: The basketball match increased cTnI levels (pre: median range]; 0.006 0.001-0.026]; peak post: 0.024 0.004-0.244] µg/L; p=0.000), with substantial individual variability in peak values. PBA and JBA players showed higher baseline and post-exercise cTnI values than ABA (all p<0.05). Peak cTnI exceeded the upper reference limit (URL) in the 26% of players (3 PBA; 6 JBA). Conclusions: The current results suggest that intermittent exercise can promote the appearance of cTnI and that this is potentially mediated by athlete status.2016http://zaguan.unizar.es/record/6203710.1515/cclm-2015-0304http://zaguan.unizar.es/record/62037oai:zaguan.unizar.es:62037info:eu-repo/grantAgreement/ES/MICINN/DEP2010-16767Clinical Chemistry and Laboratory Medicine 54, 2 (2016), 333-338All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
