The Claim
In healthy young men, higher pre-training strength is associated with smaller relative strength gains following 12 weeks of isometric resistance training, accounting for 10.6% of the variance in individual improvements.
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.
If you're already strong before starting isometric training, you won't get as much stronger compared to someone who started weaker — and this pattern explains about 1 in 10 of the differences in how much people improve.

Higher pre-training strength is associated with smaller relative strength gains after 12 weeks of isometric resistance training in healthy young men, explaining 10.6% of the variance in individual improvements.
When someone is already strong, their muscles and nerves are already working close to their maximum capacity, so there's less room for improvement when they train. Training makes nerves fire more strongly and muscles grow bigger, but if those systems are already highly active or large, the extra boost from training is smaller.
What the research says
1 studyIf you're already strong before starting this type of strength training, you won't get as much stronger as someone who started weaker — and this study proves that your starting strength explains about 1 in 10 of why people improve differently.
