The objective of this study was to compare the release of cardiac troponin T (cTnT) after a football 7 match between two cohorts of children and adult players. Thirty-six male football players (children = 24, adult = 12) played a football 7 match, and cTnT was measured before, and 3 h after exercise. Concentrations of cTnT were compared between groups and time, and correlated with participants' characteristics, as well as internal and external exercise load. Cardiac troponin T was elevated in all participants ( < 0.001), and exceeded the upper reference limit for myocardial infarction in 25 (~70%) of them. Baseline concentrations were higher in adults ( < 0.001), but the elevation of cTnT was comparable between the groups ( = 0.37). Age ( < 0.001), body mass ( = 0.001) and height ( < 0.001), and training experience ( = 0.001) were associated to baseline cTnT values, while distance ( < 0.001), mean speed ( < 0.001), and peak ( = 0.013) and mean ( = 0.016) heart rate were associated to the elevation of cTnT. The present study suggests that a football 7 match evoked elevations of cTnT during the subsequent hours in healthy players regardless of their age. However, adults might present higher resting values of cTnT than children. In addition, results suggest that the exercise-induced elevations of cTnT might be mediated by exercise load but not participant characteristics.
本研究旨在比较两组儿童和成年足球运动员在一场 7 人制足球比赛后肌钙蛋白 T（cTnT）的释放情况。36 名男性足球运动员（儿童=24 名，成年=12 名）参加了 7 人制足球比赛，在运动前和运动后 3 小时测量了 cTnT。比较了两组和不同时间点的 cTnT 浓度，并与参与者的特征以及内部和外部运动负荷相关联。所有参与者的 cTnT 均升高（<0.001），其中 25 名（~70%）超过了心肌梗死的参考上限。成年人的基线浓度较高（<0.001），但两组的 cTnT 升高程度相当（=0.37）。年龄（<0.001）、体重（=0.001）和身高（<0.001）以及训练经验（=0.001）与基线 cTnT 值相关，而距离（<0.001）、平均速度（<0.001）、峰值（=0.013）和平均（=0.016）心率与 cTnT 的升高相关。本研究表明，无论年龄大小，7 人制足球比赛后健康运动员在随后的几个小时内都会引起 cTnT 的升高。然而，成年人的 cTnT 基础值可能高于儿童。此外，结果表明，cTnT 的运动诱导升高可能是由运动负荷介导的，而不是参与者的特征。
