Abstract: (1041 Views)
Introduction: The purpose of this research was to explain the protective effect of quercetin on cardiac fatigue caused by exercise in skyrunning runners.
Methods: 26 professional sky running athletes voluntarily and purposefully participated in this race. Random people were placed in 2 groups: quercetin (13 people) and placebo (13 people). The race was held in the central Alborz mountains, the total distance traveled was 21 km and 200 meters, the altitude of the starting point was 1650 meters above sea level, the maximum altitude was 3150 meters above sea level. Before and immediately and 1 hour after the end of the race, blood was taken from the subjects. In order to check the changes of the studied variables, the independent T-test was used at the significance level of alpha 0.05.
Results: The amount of cardiac troponin T decreased significantly immediately and 1 hour after the end of the race in the quercetin group compared to the placebo group (P < 0.05). No significant difference was observed between the two groups of quercetin and placebo in the pre-test, immediately after the test and 1 hour after the test (P>0.05).
Conclusion: It seems that the increase of free fatty acids after the competition and long-term sports play an important role in reducing cardiac inotropic during the same period. Skyrunning competitions cause an increase in heart damage indices in professional athletes, despite this, quercetin supplementation reduces the increase in cardiac troponin T and can have a protective effect on the athlete's heart
