Biochemical blood parameters in serum.

LDH: lactate dehydrogenase (U/L); CK: creatine kinase (U/L); ALT: alanine aminotransferase (U/L); AST: aspartate aminotransferase (U/L); HEMO: hemoglobin (mg/DL); TPROT: total proteins (mg/DL); mg/DL; UA: uric acid (mg/DL); mg/DL. The effect of 9 days of dietary whey protein (WP) and whey protein hydrolysate (WPH) on the serum homeostasis parameters of sedentary and exercised (in treadmill) Wistar rats, the control group receiving the standard diet with casein (CAS, n = 8). The AIN93-G WP and WPH diet was made by substituting the casein (standard diet) for whey protein (WP, n = 8) or whey protein hydrolysate (WPH, n = 8). Different superscript lowercase letters indicate significant differences between the groups. ANOVA was used and the means compared (Duncan test), adopting the value of p<0.05 as the criterion for statistical significance.
