Values are presented as mean±standard deviation unless otherwise specified.

0-min: before soccer match was kicked off, P45-min: immediately after the end of the first half during soccer match, half time: 15-minute break time between the first half and the second half during soccer match, P90-min: immediately after the end of the second half during soccer match, Con: control group, CWI: cold water immersion group, IL: interleukin, TNF: tumor necrosis factor, VEGF: vascular endothelial growth factor.

Significant difference to 0-min (*p<0.05, **p<0.01, ***p<0.001), to P45-min (p<0.05, ††p<0.01, †††p<0.001), and to P90-min (p<0.05, ‡‡‡p<0.001). §Most of samples were read as a minimal detectable range.
