The Claim
Pre-training strength level is inversely associated with subsequent absolute strength gains following resistance training, explaining 10.6% of the variance in improvement.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who are already stronger before starting resistance training tend to gain less absolute strength over time compared to those who start weaker, and their initial strength level accounts for about 10.6% of the differences in how much they improve.
See the scientific wording
Pre-training strength level is inversely associated with subsequent strength gains after resistance training, with individuals who start stronger gaining less absolute strength, accounting for 10.6% of the variance in improvement.
When someone is already strong, their muscles and nerves are already working close to their maximum capacity, so adding more training doesn't create as much extra strength. Their muscles can't grow much bigger, and their nerves can't fire much more forcefully than they already do, so the gains are smaller.
What the research says
1 studyPeople who are already strong before starting weight training tend to get weaker gains in absolute strength than beginners because they’re closer to their physical limits — this study proved that pre-training strength explains about 10% of why some people improve less than others.
