Blood concentrations of glucose (a), insulin (b), urea (c) and creatine kinase (d) following intake of 20 g milk protein, WPC-80 or native whey immediately after a bout of heavy leg resistance exercise. Arrows indicates time point of protein supplement ingestion. Values are mean ± SD (only shown for highest and lowest values). n = 12 in the milk group and 10 in the WPC-80 and native whey group. Black symbols are significantly different from resting values. # native whey greater than milk at the same time point; & native whey greater than WPC-80 at the same time point, p < 0.05
