Net protein synthesis was significantly elevated at all time points. Protein synthesis in muscle tissue can occur for up to 48 hours after a resistance training session. It is important to maintain adequate protein intake during this time to ensure that muscle has the resources to build new tissue. The subjects in this study were untrained. Results may have been different for trained subjects.
More research is needed on trained subjects.
Research also needs to examine the length of the time period that protein synthesis continues at an elevated rate after a resistance training session. In this study, protein synthesis was still significantly higher than resting levels at 48 hours postexercise. Future research should look at a larger time window, i.e. 96 hours and longer. S.E.
