The primary finding of the present study is that despite similar changes in plasma EAA responses, adding a novel amylopectin/chromium-containing complex to a suboptimal dose of whey protein magnified the increase in MPS from protein intake and resistance exercise (assessed four hours post-ingestion). A key strength of our study design is the randomized, counter-balanced, within-subject crossover approach we used to examine the potential differences between the two experimental conditions.
