Group	LA (mmol/L)	IL-10 (ng/L)	IL-10/TNF-α
C	5.90 ± 0.97	72.51 ± 8.65	0.56 ± 0.08
E	19.07 ± 3.34**	85.47 ± 11.82*	0.52 ± 0.07

Group C was a sedentary control group, Groups E+TP and Group E performed a single exhaustive swimming test; all groups had normal diets, but Group E+TP was supplemented with tea polyphenols. ** p < 0.01, * p < 0.05 vs. control group; ## p < 0.01, # p < 0.05 vs. exercise group. LA: lactic acid; IL-10: interleukin-10; TNF-α: tumor necrosis factor-α.
