Effect of BTE vs PLA on plasma GSH:GSSG ratio at baseline, 0, 30, and 60 min post exercise. Data were normalized via log10 transformation. BTE had higher GSH:GSSG ratio at 30 and 60 min post exercise compared to PLA. § represents (P < 0.001) difference from baseline within condition. * represents (P < 0.01) difference between conditions within time.
