Protein and Amino Acid Supplementation Does Not Alter Proteolytic Gene Expression following Immobilization

Table 2

Dietary values assessed prior to the three testing sessions for placebo (PLA) and protein/amino acid (PAA) groups. All data are presented as mean ± standard deviation. Results indicated a significant difference between groups at days 14 and 28 for total protein and relative protein (𝑃<0.001) and a significant change from baseline over time for the PAA group (𝑃<0.001). *Denotes a significant time effect and ^†denotes a significant difference between groups.
