The present study employs a crossover design. In total, 12 healthy young male subjects will be included in the study. Subjects will be randomly assigned to consume minced beef or milk during trial one. During the test day, subjects will perform leg extension exercise and immediately afterwards consume 35 g of protein either as minced beef or milk. Approximately, two weeks later subjects will return to the laboratory for the identical experimental procedures as trial 1, which includes exercise that is worked-match to trial 1 and consumption of alternative protein source that was not consumed in trial 1.
