The Claim
In healthy older men, lower baseline levels of maximal voluntary contraction strength, rate of force development, and type II muscle fiber size are associated with greater relative improvements in muscle performance following heavy resistance training, although baseline values do not fully account for the inter-individual variability in training response.
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.
Older men who start out weaker or with smaller fast-twitch muscle fibers tend to get bigger gains from heavy weight training, but even knowing how weak they were at the start doesn’t fully explain why some people improve more than others.

What the research says
1 studyThe study found that older men who started out weaker or with smaller fast-twitch muscle fibers tended to improve more after weight training, but even that didn’t explain why some people improved way more than others — just like the claim says.
