The Claim
Twelve weeks of whole-body resistance exercise training performed three times per week increases one-repetition maximum leg extension strength by 38% in adults aged 65–75 years and by 46% in adults over 85 years, with no statistically significant difference in strength gains between the two age groups, indicating that maximal strength improvements from resistance training are preserved in the oldest-old population.
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 adults, even those over 85, can gain just as much leg strength as younger seniors from 12 weeks of regular weight training — and some even gain a bit more!

Twelve weeks of whole-body resistance exercise training three times per week increases one-repetition maximum leg extension strength by 38% in adults aged 65–75 years and by 46% in adults over 85 years, with no statistically significant difference in gains between age groups, suggesting that maximal strength improvements from resistance training are preserved even in the oldest-old.
What the research says
1 studyThe study looked at the exact same type of strength training and age groups mentioned in the claim, and found that both older and very old adults gained similar amounts of leg strength.
