The Claim
Inter-individual variability in response to heavy resistance training in healthy older men is substantial and exceeds measurement error for key outcomes including maximal voluntary contraction strength, rate of force development, and type II muscle fiber hypertrophy.
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.
When older men do heavy weight training, some get much stronger and build more muscle than others—even when they do the same workout—and those differences are bigger than any mistakes we might make when measuring them.

What the research says
1 studyThe study showed that when older men lift heavy weights, some get much stronger and bigger muscles than others—even when they follow the same program—proving that people respond very differently, and it's not just because of measurement mistakes.
