Protein: So, when you get that protein content number, I usually start with explaining to clients that nitrogen makes up anywhere from 16%-32% of the structural weight of amino acids, and contribute directly to formation of nucleic acid- all major components of protein synthesis and in extension building of muscle tissue. Consuming a diet rich in protein is the number one way of increasing nitrogen content and achieving a positive nitrogen balance which is needed during a phase of caloric deficits to maintain lean mass or a caloric surplus if muscle gain is the goal.
So, if they are scanning in an ideal state (rested, hydrated, relaxed, and recovered from their previous training), and following nutritional advice on protein recommendations this measurement should be “High”, classically those clients that under eat, struggle with recovery, or are plant based this measurement will be lower. This number essentially shows how much amino acid is being stored in the muscle cells at the time of the scan. More amino acids typically indicate a higher chance of protein synthesis.
