The Effect Aerobic Maximal Workload exercises on cardiac damage biomarkers of Irain football primier league players

Given the prevalence of heart attacks and sudden deaths in sports, it is very important to study the effects of various sports activities on such factors in identifying the causes of heart injuries caused by sports. The aim of this study was to investigate the Effect Aerobic Maximal Workload exercises on cardiac damage biomarkers of Irain football primier league players.The present study was a quasi-experimental study. The statistical population of the present study was the players of the Iranian Football Premier League in the ۲۰۲۰-۲۰۲۱ season. From this community, ۲۰ football players were selected as available samples. Evaluation of aerobic activity was incremental to maximal by implementing the Bruce protocol. Before the protocol, blood samples were taken immediately after the end of the protocol and after ۲۴ hours of the second blood draw. Blood samples were sent to special laboratories for analysis of cardiac biomarkers. To test the hypotheses and compare the dependent variables in different groups, analysis of variance in repeated measures was used and Bonferroni test was used to compare between blood sampling steps. The collected data were analyzed using SPSS۲۵ software.According to the results, no significant difference in the amount of galactin-۳ was observed between the pre-test stage and immediately and ۲۴ hours after the test (P = ۰.۰۸۹). The results also showed that there was a significant difference in CTnI and CTnT before and after the test (P = ۰.۰۰۰), CTnI and CTnT levels increased significantly immediately after the test and then returned to baseline ۲۴ hours later. Also, a significant difference in Brain Natriuretic Peptide (BNP) was observed in the pretest, immediately and ۲۴ hours after exercise (P = ۰.۰۰۱). Cerebral natriuretic levels increased significantly immediately after the test and decreased significantly ۲۴ hours later and ۲۴ hours later and Returned to the original levels.It can be concluded that increasing aerobic exercise 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.
