Figure 2. The free radical scavenger activity (FRSA) of saliva collected from (a) male and (b) female athletes at various time points.

Figure 2

FRSA (%)  =  ((Ac - As) ÷ Ac) ×100, whereas Ac and As represents the absorbance with the addition of PBS and saliva samples from either ingestion of water (white bar) or green tea (slashed bar), respectively. Significant difference between each sampling time and the initial condition (BT) was set at # P<0.05. BT, before training; AT, after training; Rec, 30 min of recovery after ingestion of water or tea.
