The Effect Aerobic Maximal Workload exercises on cardiac damage biomarkers of Iranian football premier league players

The aim of the present study was to investigate the effect of increasing to maximal aerobic training on biomarkers of heart damage in Iran's Premier Football League players.The present study was a semi-experimental research. From among this society, 20football players were selected as available samples. The assessment of incremental aerobic activity to the maximum was by implementing the Bruce protocol. In order to test hypotheses and compare dependent variables in different groups, analysis of variance test was used in repeated measures, and Bonferroni test was used to compare between blood sampling stages. The analysis of collected data was done using 25SPSS software.According to the results, there was no significant difference in the amount of galectin-3between the pre-test phase and immediately and 24 hours after the test. Also, there was a significant difference in CTnI and CTnT in the pre-test and after the test. CTnI and CTnT levels increased significantly immediately after the test. and then returned to the initial state 24 hours later. Also, a significant difference in brain natriuretic peptide (BNP) was observed in the pre-test, immediately and 24 hours after the exercise. Brain natriuretic levels increased significantly immediately after the test and decreased significantly after 24 hours and returned to the initial levels 24 hours later. It can be concluded that aerobic exercise increasing to the maximum may lead to an increase in cardiac specific troponin I and T and brain natriuretic peptide. However, the increase appears to be temporary and does not cause heart damage.
