The Comparison of Beet Juice and Ibuprofen Consumption on Muscle Damage after a Session of Resistance Exercise in Young Untrained Women

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 ۲۴ young women (۲۰-۳۴ years old) who were randomly divided into two groups of beetroot juice (n=۱۲) and ibuprofen (n=۱۲). The beet juice group received ۴.۵ ml of natural beet juice per kilogram of body weight about ۱۵۰ minutes before the activity, and the ibuprofen group received ۳۰ mg of the drug ۲۴ hours before the activity in three meals before the activity. they received. Both groups performed resistance activities including ۶ movements of the upper body and lower body in ۳ times of ۱۵ to ۲۰ repetitions with ۶۰ to ۷۰% 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 ≥۰.۰۵. The results showed that although the serum creatine kinase and myoglobin levels in both groups showed a significant increase compared to pre-activity (p=۰.۰۰۰۱), no difference was observed between the groups (p=۰.۰۹۴ and p=۰.۲۱۱). Also, while the increase in plasma interleukin-۶ 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=۰.۰۰۱). These results show that ibuprofen reduces the inflammation caused by these exercises to some extent.
