I’m going to use this page to organize supplement and workout publications that I find. It won’t be the best sorting ever but it shouldn’t be too hard to follow.
Amino Acids
Postexercise net protein synthesis in human muscle from orally administered amino acids
We concluded that ingestion of oral essential amino acids results in a change from net muscle protein degradation to net muscle protein synthesis after heavy resistance exercise in humans similar to that seen when the amino acids were infused.
Glycogen
Effects of depletion exercise and light training on muscle glycogen supercompensation in men
In conclusion, a CHO-loading protocol that begins with a glycogen-depleting exercise results in significantly greater muscle glycogen that persists longer than a CHO-loading protocol using only an exercise taper.
Insulin
Effect of physiologic hyperinsulinemia on skeletal muscle protein synthesis and breakdown in man.
Since phenylalanine is not metabolized in muscle (i.e., its only fates are incorporation into or release from protein) these results strongly suggest that in normal man, physiologic elevations in insulin promote net muscle protein anabolism primarily by inhibiting protein breakdown, rather than by stimulating protein synthesis.
Physiologic hyperinsulinemia stimulates protein synthesis and enhances transport of selected amino acids in human skeletal muscle.
We conclude that insulin promoted muscle anabolism, primarily by stimulating protein synthesis independently of any effect on transmembrane transport.
Euglycemic hyperinsulinemia augments amino acid uptake by human leg tissues during hyperaminoacidemia
The results suggest that insulin, given with sufficient amino acids, may stimulate leg and whole body protein balance by mechanisms including stimulation of protein synthesis and inhibition of protein breakdown.
