New lifters might grow more from stretching muscles than experienced lifters, but we don’t know for sure because most studies use beginners.
Scientific Claim
The hypertrophic response to training at longer muscle lengths may differ between untrained and trained individuals, but current evidence is insufficient to determine this due to limited data in trained populations.
Original Statement
“Much of the research we have involves varying levels of training experience as well as small sample sizes. The new study was conducted on previously untrained individuals and a number of other studies across the categories were also conducted on previously untrained individuals. Thus, it's impossible to be confident about whether certain things are more beneficial for untrained or trained individuals.”

This study found that even people who already lift weights can get slightly more muscle growth by training with their muscles stretched out, which means we now have proof that trained people respond to this kind of training — something we didn’t know much about before.
Does longer-muscle length resistance training cause greater longitudinal growth in humans? A systematic review
This study looked at whether lifting weights with muscles stretched more leads to bigger muscle growth, but none of the studies compared people who are new to lifting versus those who are experienced — so it agrees that we just don’t know enough yet about how trained people respond.
