Integrated MPS: myofibrillar protein synthesis considering the first 48h (i.e., 0 to 48h) after a single resistance exercise bout; T1: first week, T2: third week, T3: last week of training. MPS data from Damas et al. [10].
*Significant (P < 0.05) correlation. Bold numbers indicate high correlation between variables.
