Fig. 3. Changes in (A) pH, (B) HCO3–, (C) PO2, (D) PCO2, (E) oxygen saturation, (F) hematocrit (Hct), (G) hemoglobin (Hb), (H) glucose, (I) lactate, (J) sodium, (K) potassium, (L) calcium concentration following CWI and Con. Significant difference to 0-min (main effect of time, *p<0.05, **p<0.01, ***p<0.001), P45-min (†p<0.05, ††p<0.01, †††p<0.001), P90-min (‡p<0.05, ‡‡p<0.01, ‡‡‡p<0.001). Significant difference from Con (main effect of group, §p<0.05, §§p<0.01, §§§p<0.001). Significant difference to P45-min and P90-min (&&&p<0.001). Values were expressed by means (standard deviation). Con: control group, CWI: cold water immersion group, 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.
