چکیده
Introduction: Available scientific data related to cardiac troponin I (cTnI) release after intermittent exercises is limited. It is also of interest to determine the concentration of troponin in the runner of track and field. This study had two objectives: evaluate the level of troponin in professional and amateur runners after endurance exercises.
Methods: Thirty runners (15 professional adults 27.3±4.1 years, 15 amateur adults 29.6±2.9 years) participated in a protocol of endurance exercises that consists of the distance exercises with principles of interval and distance exercises.
Results: After endurance exercises cTnI levels increased (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. Findings showed that professional runners had higher baseline and post-exercise cTnI levels than amateur runners(p<0.05). Peak cTnI exceeded the upper reference limit (URL) in the 26% of players.
Conclusions: The current results suggest that endurance exercises can increase the level of cTnI, which is mediated especially by professional runners.
