Study design. All participants were studied during four experimental test days (≥1 day apart and ≤2 days per week) within a time frame of one month. The responses to four different protein drinks were examined according to a randomized cross-over design. Time points t = −20, −10 and 0 min were used to analyze postabsorptive protein metabolism. Postprandial protein kinetics were measured by using the time points t = 0 −240 min in order to calculate the area under the curve between 0 and 4 h.
