Data were normalized via log10 transformation. A time main effect for IL-6 occurred across both conditions. No significant differences in IL-6 levels between conditions were observed. § represents (P < 0.001) difference from baseline

within condition. Discussion Results of the current study indicate that, in comparison to the placebo, supplementation with BTE resulted https://www.selleckchem.com/products/Cediranib.html in increased baseline antioxidant status, reduced oxidative stress response to anaerobic exercise, improved HPA axis recovery, greater average peak power and average mean power across nine WAnT intervals, and lower DOMS ratings 24 and 48 hours after anaerobic exercise. These findings may hold practical significance for physically active individuals or athletes involved in training that requires high intensity, acute bouts of anaerobic exercise. It is possible that the antioxidant benefits from black tea may translate beyond disease and can have potential

for improving recovery of oxidative stress and inflammation after exercise. The reduced oxidative stress response observed with BTE supplementation may be due to the antioxidant effects of the theaflavin component of the BTE supplement, or to the ability of the BTE supplement to increase endogenous HM781-36B in vivo antioxidants such as GSH. Consistent with the oxidative stress results, the high intensity anaerobic exercise with BTE supplementation also elicited a lower cortisol secretion. Possible explanations include blunting of the activation of HPA axis or potentially the recovery HMPL-504 cost from HPA axis activation was more enhanced. It is important to note that oxidative stress occurred post-exercise under both conditions (supplementation with BTE or PLA). Elimination of this response would be undesirable as it is essential for muscle repair and hypertrophy [1, 10, 12]. The oxidative marker results reveal that oxidative stress was initiated to similar degrees across conditions

yet the recovery was more pronounced with BTE supplementation. Previous research has revealed that IL-6 is the most responsive cytokine to exercise [22] and its appearance in the blood not only precedes the other cytokines but is also more distinct [15]. In this selleck kinase inhibitor study, plasma IL-6 significantly increased post-exercise and remained elevated through 60 min of recovery in both BTE and PLA. Though, graphically, the response appeared to be slightly blunted for BTE, this result was not significant. It is likely that the previously demonstrated anti-inflammatory effects of BTE [19] were overpowered by the sheer intensity of the anaerobic exercise testing protocol used in the current study. The magnitude of the CORT and oxidative stress responses serve to reinforce this notion. It is also possible that any anti-inflammatory effects of BTE appeared later in the recovery period after assessments were completed at 60 min post.
