There are 2 processes that keep a muscle cell more anabolic:

1) Muscle protein synthesis
2) Muscle protein degradation

Whey has been shown to  help increase muscle protein synthesis and spikes blood amino acid levels, but because it is fast digesting its benefits are not prolonged.

Casein has the capability of keeping blood amino acid levels elevated for a prolonged period of time, when compared to whey protein. This reduces muscle protein degradation by allowing the body to use amino acids in the blood for more important functions than muscle building.
