How does muscle growth actually progress over time?
Our new systematic review and meta-analysis, posted as a preprint (DOI:10.51224/SportRxiv.910), pooled 3,237 observations from 480 studies to model the trajectory of resistance training-induced muscle growth.
As expected, muscle growth follows a curvilinear trajectory.
Gains occur relatively rapidly during the early stages of training and then progressively slow as training continues. At 10 weeks, the model estimated an average increase in muscle size of approximately 7%.
It will be really nice if we get to a point where a generic starter routine can be derived, such that the response to the routine can provide insight into responsivity to training and help people know how to change the stimulus productively over time. Yesterday
