Abstract
The aim of this study was to compare the consumption of two combinations of beetroot juice and ibuprofen before exercise on muscle damage indicators after a session of isotonic resistance exercise. The samples of this research consisted of 24 young women (20-34 years old) who were randomly divided into two groups of beetroot juice (n=12) and ibuprofen (n=12). The beet juice group received 4.5 ml of natural beet juice per kilogram of body weight about 150 minutes before the activity, and the ibuprofen group received 30 mg of the drug 24 hours before the activity in three meals before the activity. they received. Both groups performed resistance activities including 6 movements of the upper body and lower body in 3 times of 15 to 20 repetitions with 60 to 70% of the maximum strength, and at the end, in two stages, the levels of creatine kinase and blood myoglobin were evaluated. The data were analyzed using the independent t-test at an error level of p ≥0.05. The results showed that although the serum creatine kinase and myoglobin levels in both groups showed a significant increase compared to pre-activity (p=0.0001), no difference was observed between the groups (p=0.094 and p=0.211). Also, while the increase in plasma interleukin-6 concentration in the beetroot juice consumption group had a significant increase compared to before the activity, the concentration of this variable in the ibuprofen consumption group had a slight change (p=0.001). These results show that ibuprofen reduces the inflammation caused by these exercises to some extent.
